How to unscrew the oil filter without a key? 5 ways to choose

Regardless of why you don’t want to go to a car service to change the oil in your car’s engine, the oil will still have to be changed after a certain period of time (mileage). And with it the oil filter. And this filter sometimes gets stuck so that even though you wrap it by hand, it is not possible to unscrew it without special tools. In our article we will offer four effective ways to unscrew the oil filter without a key or a special puller in a regular garage.

What happens to the car if the filter is clogged?

Untimely replacement of the oil filter on Logan can significantly affect the operation of the oil system and the engine in particular.
Chips from friction of the surfaces of parts, dirt and dust from routes - all this passes through filtration along with the engine oil and enters the engine. The operating period of oil filtration is one year. The manufacturer recommends changing consumables every 15-20 thousand kilometers or once every 12 months. At the same time, once every six months you should look into the system and check the condition of the spare part. It is not always possible to follow the manufacturer's instructions - the operation of the filter is influenced by many factors that significantly reduce its service life.

Signs of a clogged filtration:

fuel consumption increased;
the car stalls and moves jerkily on inclines;
engine power and thrust decreases;
oil leakage, which leads to clogging of the element;
slipping at idle;
uncontrolled braking of a vehicle;
difficult to start the engine the first time;
the dynamic characteristics of the engine are reduced.

If you change the filter in a timely manner, as it wears out, you can prevent unwanted global repairs, which are ten times more expensive than the corresponding replacement process. By choosing a high-quality spare part, you can ensure uninterrupted cleaning of the engine fluid from decay products and dirt for a certain service life of both the engine oil itself and the filter device.

The most important failure of a part is damage to the housing or filter cassette. If the cassette is easy to replace, you just need to buy a new one and carry out repairs, but the body itself is difficult to change - due to its inconvenient location, a thorough repair will be required. If you strictly follow the recommendations described in this article, you can easily cope with replacing the oil filter on a Renault Logan alone.

Method 3: Using a leather trouser belt

If you don't have an old timing belt at hand, a regular leather belt will do just fine.

The principle is as follows: the belt is put on in a loop and tightened with force. In this case, the long end of the belt serves as a lever.

Do not forget that the oil filter is unscrewed counterclockwise.

The most important thing is that the filter housing is clean, otherwise the belt will slip. For better contact, the surface of the filter can be slightly sanded.

Everything is very simple here: a deep notch is made on the filter body on the thread side, then a chisel is inserted into it and the filter is torn off the thread with tangential hammer blows.
Next, the filter element is unscrewed by hand. This method is rarely used, since the free space around the filter is limited and there is practically no room for such maneuvers.

The oil filter does not unscrew: what to do?

If you can’t unscrew the oil filter yourself, you can suggest that someone who has more strength try to do it. In most cases, you can unscrew even a strongly “stuck” oil filter without unnecessary tricks. But when you cannot unscrew the element even with outside help, you can use one of the methods described below:

Special wrench for oil filters. In automobile accessory stores you can find a special wrench designed to unscrew oil filters of various diameters. It is enough to hook such a key onto the element and then start rotating. Using it to unscrew the oil filter is not difficult, but not all drivers have such a key, and you must first purchase it;
Creating a lever. In the garage you can always find a lot of unnecessary parts and various tools from which you can build a lever. For example, you can put an old timing belt or generator belt on the key, then tie it around the filter and start rotating. Due to the unique lever and the absence of rubber sliding on the oil filter, unscrewing the element will not be more difficult than using a special wrench;
Screwdriver and hammer. A simple and effective method that is suitable if you are not afraid of getting dirty in oil. It implies that a screwdriver must be driven through with a hammer into the oil filter. When the filter is broken, you can use a screwdriver as a lever, unscrewing the consumable element. It should be understood that if the oil filter is broken, residual oil will flow out of it;

Please note: Some drivers recommend not punching through the filter with a hammer, but rather driving a screwdriver into the area of the mounting location with a hammer. Doing this is quite dangerous, since the screwdriver may accidentally fall off and pierce the engine components.

Reasons why the oil filter is not dismantled

To unscrew the old filter, you need to place the car on a pit or lift the car using a lifting device. Then you need to unscrew the old filter, but difficulties may arise here. If it does not come off, this may be due to its sticking. The motor becomes very hot during operation. Because of this, parts that are not very heat-resistant melt. Such components include a rubber gasket, which is included in the design of the oil filter. It can melt and stick to the engine, especially if oil gets on the gasket.

Problems arise when the filter is twisted too tightly. When changing the filter element, you need to tighten it well so that the rubber band is pressed tightly against the motor. In this case, the oil filter is often screwed on too tightly, especially when using a wrench. If you take into account the melting of the gasket, it becomes clear that unscrewing the filter will be enough.

It is important that the oil filter is not located in the most convenient place, therefore, it becomes impossible to exert maximum effort to unscrew it. In addition, when unscrewing, your hands get dirty with oil and slip.

Selection of oils

Now to the question of what kind of oil to pour into the engine of the French Renault Logan car. According to the recommendations of the automaker itself, oil produced by Elf is optimally suited for their cars. They work closely together, which is why only this liquid is indicated in the instruction manuals.

The main recommendations for this car are two oils from Elf from the Evolution series:

Also in demand are:

Turbo Diesel 10W40;
Competition ST 10W40;
Solaris RNX 5W30;
Excellium LDX 5W40, etc.

Elf's line of motor oils includes universal lubricants, fluids designed for specific engines, as well as separate series for automatic and manual transmissions.

If you ask the owners of such cars about what kind of oil they use, the majority is inclined to think that Renault’s recommendations are correct, and the engine works well with these oils. There are also experiences with unsuccessful oil changes.

As for the type of oil, there are 2 options to choose from.

Semi-synthetic. It is better to use it on cars whose mileage is already more than 100 thousand kilometers. Its thicker consistency helps prevent leaks through worn gaskets and seals. Well suited for winter as it easily starts the engine at low temperatures.
Synthetics. Suitable for newer cars. Synthetic lubricants are recommended for use on all modern cars and their engines. Great fluidity and stability of physical and chemical characteristics guarantee protection against overheating, wear and frost.

Therefore, focus on the age and mileage of your Renault Logan when choosing between synthetics and semi-synthetics. Just keep in mind that when changing the oil, be sure to change the following in parallel:

oil filter;
gasket for the drain plug (made of copper).

This will allow the engine to run better with fresh oil and prevent unwanted lubricant leaks.

Inconveniences for the driver

Car modifications have individual principles for attaching the oil filter. What remains common is the lack of space around them, since the layout of the power units is so compact that it is almost impossible to “crawl” in to screw together the oil cup. Difficulties include the adhesion of rubber seals to metal.

Based on the above, they conclude that a specific engine requires “its own” device or universal puller. When developing your own design, you need to focus on factory analogues of oil filter pullers sold in car dealerships.

Changing the oil in the Renault Logan 2 engine

Changing the engine oil is a process that, according to the manufacturer of Renault Logan 2, should be done once every 15,000 km. If the annual mileage is less, then new working fluid is added to the engine once a year. Simultaneously with replacing the engine oil, other elements are also replaced - the oil filter (required) and the drain bolt washers (depending on their condition). The catalog number of the original washer is 110265505R.

The Renault Logan 2 manufacturing plant fills various engines with Elf Excellium LDX 5W40 oil. In the future, when replacing, the following engine oils are recommended:

For engines with eight valves, Elf Evolution SXR oil with a viscosity grade of 5W30 is suitable. The required volume of lubricant for replacement is 3.3 liters.
For 16V (K4M) engines, Elf Evolution SXR is used, with a viscosity grade of 5W40. Here it is advisable to prepare 4.8 liters of working fluid.

If you choose an alternative option, you should pay attention to motor oils that comply with the following API classes - SL, SN and SM, as well as ACEA A5 and A3. When determining the appropriate lubricant viscosity for your engine, you must base it on the temperature that prevails in your region:

When determining the appropriate lubricant viscosity for your engine, you must base it on the temperature that prevails in your region:

At temperatures of 30 degrees below zero and above, it is recommended to use SAE 0W30 or 0W40 oil.
If the thermometer in winter does not fall below 25 degrees below zero, then compositions with the following SAE viscosity are suitable - 5W30, 5W50 and 5W40.
For regions where winter does not get colder than 20 degrees below zero, motor oils with the following SAE viscosity are suitable - 10W30, 10W50 and 10W40

Currently reading: Renault Logan vs Volkswagen Polo Sedan: budget race
Car owners often prefer Excellium NF 5W40 oils, but when choosing this brand, changing the oil to a composition with a W30 viscosity is prohibited. The reason is that a lubricant with a higher viscosity cokes more.

Is it possible to determine the suitability of a filter?

It is impossible to do this by appearance. Mileage won't tell you anything either: the car can be used in different conditions. It would be fairer to take into account not only the number of kilometers traveled, but also the engine hours.

As mentioned above, riding style is also important. Drivers who prefer it are better off focusing on expensive products. This is due to the fact that during sudden acceleration or stopping the engine requires a large amount of lubricant. And expensive filters contain synthetic elements that cope well with high loads, temperatures and quickly remove the lubricant. If you are a fan of a quiet way of transportation, you can purchase less expensive products that have a felt base. The oil in them takes longer, but you don’t need it any faster.

Safety precautions when replacing the oil filter

The vehicle must be securely secured.
Work should be carried out outdoors or in a well-ventilated area due to the flammability of the materials.
You should work in safety glasses, work clothes and household gloves.
The used oil must be completely drained before starting work.
The oil and oil filter are replaced with the engine warmed up to normal temperature. Avoid touching the engine, clutch mechanism, gearbox and structural elements of the exhaust system with unprotected areas of the body.
After the oil is drained, some of it remains in the filter. When carrying out work, you must position yourself relative to the filter in such a way as to prevent hot oil from getting on your body.
Oil and oil filter are environmentally hazardous materials and must be disposed of as industrial waste.

Replacement instructions

Changing the oil on a Renault Logan yourself does not require any special skills or any knowledge. Try to act carefully, consistently and do not forget about safety measures. First, we note that the replacement procedure on 8-valve 1.4 and 1.6-liter engines is slightly different from the 16-valve engine, so we will consider it separately. Let's start with 8-valve engines.

To work, it is better to park the car in a pit. Some people make do with a jack, but this is dangerous and inconvenient. Having placed the car over the pit, place chocks under the wheels and turn on the handbrake on your Logan. It is better to remove the negative terminal from the battery, since there is a high voltage wire near the filler hole.

To make the lubricant flow out faster, increase the fluid fluidity level by warming up the engine a little. This will make the oil change more intensive, plus you will be able to get rid of the maximum amount of old lubricant in the engine. Do not overheat the engine, otherwise hot oil will end up on your skin when drained, causing serious burns.

Up to 50 degrees is enough. Unscrew the plug for filling in fresh oil to eliminate vacuum when draining old lubricant. He finds a drain plug under the car. The cork is unscrewed with a 4-sided tool, the holes for which are usually dirty. So clear them and insert the key

An important feature of these motors is that it is not necessary to remove the engine protection to drain the liquid. There is a special hole for easy access to the neck.

Carefully loosen the plug and turn it 2–3 turns.

Now we substitute an empty container for drainage and unscrew the plug completely. Be careful not to let the oil spill on you. This is why rubber protective gloves are needed. While the grease is flowing out, take the oil puller and remove the old filter.

It is located in the front part near the exhaust manifold. Clean the filter seat and remove the old gasket. Before installing, lightly lubricate the rubber ring on the new filter with oil. Fill 50% of its volume with fresh lubricant inside the filter itself.

When the oil is drained, wipe everything with a rag, be sure to change the copper ring on the plug and screw it into place. Here, too, medium tightening efforts are needed. We begin to fill in fresh engine lubricant. 8-valve engines of 1.4 and 1.6 liters. First add only 3 liters.

We add everything else, following the marks on your dipstick. When it shows the level halfway between o and "Max", close the cap and warm up the engine for 20 seconds. The oil lamp on the instrument panel should go out. 10 minutes after turning off the engine, take the dipstick again and check the level. If necessary, add a little oil.

The procedure is simple, but requires your attention and compliance with safety rules. Replacement is carried out literally in 1 hour.

How to unscrew the oil filter with a special wrench

There are many types of pullers. Here is a description of some of them:

Tape. Handle with a grip in the form of an open ring made of steel tape. One end is attached through a hinge to the handle itself, the second - through a hinge to the movable rocker arm. When you turn the handle counterclockwise, the rocker starts to move, the ring moves together, decreasing in diameter, the tape wraps around the filter body and sets it in motion.
Belt. The principle of operation is very similar to belt ones, but only one end of the belt is attached to a hinge to the rocker arm. The second one is free. The free end is wrapped around the body, passed into the rocker arm, and the belt is “pinched” by turning the handle counterclockwise. Continuing the movement of the handle, unscrew the stubborn element.
Chain. A loop from a chain, similar to that from a timing belt or bicycle, is clamped in a head with a hole for the square of the handle from the set with socket heads. They wrap the filter in a loop, insert a square into the head, and wind the chain around the head until it clamps the housing and turns it.
Ticks. Keys modeled after pliers. They consist of two handles with semicircular toothed girths on a hinge joint. They work like a locksmith's analogue.
Crescent-shaped. With one handle, one movable serrated girth and a fixed short serrated end. A simplified version of the previous key.
End, cup-shaped. Puller heads. For professionals, they are sold in the form of kits for different sizes of oil filters. You can buy only one for a specific car make and type of filter element.
Crabs. They belong to universal end pullers with three movable self-clamping “legs” at an angle of 120° relative to each other. They are activated, like the cup-shaped ones, by a square inserted into the hole at the end of the key.

The vicissitudes of the process

The filter screws in and out very easily. Everything is clear with screwing. We twist it until it stops, then tighten it, clasping it with both hands - and that’s it. Often, with some effort, the filter can also be torn off manually. But those who are wondering how to unscrew the oil filter without a key clearly have problems with the unscrewing procedure. The main thing here is to tear it out of place, that is, turn it once at least a couple of centimeters. And then things will go on their own, he will unscrew it by hand as easily as he screwed it in.

What is the best oil to put into the engine?

The necessary data on the frequency of engine oil changes, the recommended brand and quantity are usually indicated in the user manual or technical passport of the car. Before you start changing the oil, it is advisable to read this documentation.

Despite the variety of motor oils, it is still worth adhering to the recommendations of the car manufacturer. However, this does not mean at all that it is necessary to purchase exactly the officially recommended oil recommended by the Renault concern - it is not the brand of oil that plays an important role, but its specifications.

Renault on its official website recommends ELF oils for warranty and after-sales service.

After determining the manufacturer's recommendations, it is advisable to find out what was poured into the engine before. If the car is just yours, then there will be no problems with this. If the vehicle was bought secondhand, then it is worth checking with the previous owner what brand of motor oil he used.

Constantly changing the oil has a negative effect on your car's engine. Accordingly, it is advisable to select either the brand of oil that has already been filled in, or one that is close in terms of the characteristics indicated on the packaging to the manufacturer’s recommendations. However, there are times when it is still worthwhile to change the oil to another brand - for example, if its consumption is too high.

In such situations, it is better to choose high-viscosity oil. By the way, this or that type of engine oil is indicated not for a specific car, but for the engine installed in it. Accordingly, the oil is selected based on the additives and properties allowed for the engine.

Ideally, you can purchase the required engine oil from an authorized Renault dealer in the city. Of course, this option is very expensive, but it’s still worth asking about prices - official dealers often offer significant discounts to regular customers.

Why does the oil filter need to be replaced regularly?

Over time, the oil filter gradually becomes more clogged as it traps billions of contaminants and carbon dust. A clogged filter reduces the amount of clean oil passing through it and therefore requires regular replacement.

The oil filter is a sealed metal unit, so you can't do a visual inspection to determine when it needs to be replaced. There are no devices, sensors or warning lights to remind you that it's time to change the filter. You won't even notice the impact a clogged or dirty oil filter has on your engine. The effects of a clogged or dirty filter may include some or all of the following:

Lack of engine lubrication.
Premature engine wear.
Internal engine damage.
Reduced oil pressure.

Even though your engine may be experiencing these problems internally, you won't realize it until it's too late and your engine is damaged. For proper operation of the engine, a huge amount of clean oil is required.

To protect against clogging, premium oil filters contain a bypass valve that regulates the pressure directly inside them. If the filter becomes completely clogged, this bypass valve will open and oil will continue to circulate through your engine. However, the oil will be dirty and "unfiltered".

Volume of oil to be filled and checking it

Based on the official factory instructions, the amount of oil poured into the engine depends on the number of valves on the engines and their volume. Therefore, be guided by the following data:

for Renault Logan engines with 16 valves with a volume of 1.6 liters. 4.5 liters of lubricant required;
if it is a 1.4 and 1.6 liter engine with 8 valves, then prepare at least 3.35 liters of lubricant.

The level is checked for preventive purposes during vehicle operation. Some do this almost every day, others use the dipstick to determine the engine oil level only once a month, or even less often. Every car owner is required to monitor the oil level in his engine. It should always be at the optimal value, which guarantees effective lubrication of all components.

If the oil in the Renault Logan engine begins to leak, the level will gradually drop. This should definitely be checked. Almost every motorist knows how to do this. You need to take out the dipstick, wipe it dry, insert it back, twist it a little and pull it out.

You can also take a few drops of oil with a dipstick every 2–3 months when the machine is actively used and drop them onto a white cloth or paper. This way you will see if there are any extra particles, how clean the oil is and whether its color has changed. Such changes indicate premature wear of the lubricant, which should be changed.

Just keep in mind that the loss of a lubricant’s physical and chemical properties ahead of schedule indicates the presence of some problems in the engine itself. Therefore, before pouring several liters of new lubricant, it is recommended to check the condition of the power unit for malfunctions. Otherwise, the same thing will happen with new oil.

Which way to unscrew the oil filter?

When difficulties arise with unscrewing the filter element, the motorist may begin to be tormented by doubts regarding which direction the device should be unscrewed. Remember that the oil filter must be unscrewed counterclockwise (to the left). In the same way, a regular nut or bolt is unscrewed (if you do not take into account fasteners with reverse threads).

If you cannot unscrew the oil filter on your own, ask a stronger person for help. In fifty percent of cases this method works. The main thing is to achieve a breakdown from the starting point. This is easier to do with a warm engine. When the engine cools down, it becomes difficult to unscrew the filter.

For dismantling, you can use one of the following methods:

One of the factory oil filter wrenches

1. Special key. In stores selling car accessories, you can find a wrench that is designed to unscrew the oil filter. It can be one of three types:

chain;
crab;
clamping

Such a tool needs to be hooked onto the filter. After that, start rotating it.

Using a poly V-belt to unscrew the filter

Surely many people have a used drive belt for a generator or air conditioning compressor; this is a rubber belt with longitudinal grooves. A timing belt can also be suitable, which can also effectively wrap around the filter body. Next, unscrew it using several methods.

If the filter can only be accessed from below, like I do, then you can put the belt in regular pliers, wind the free part of the belt around the filter, then rotate the pliers and wind the rest of the belt around the jaws of the pliers, when it gets taut, you can rotate the pliers themselves around the filter, which give more force to unscrew than trying to do it by hand.

This method is discussed in more detail in the video clip, which is located just below all the methods on the topic of belts.

In general, there are a lot of methods associated with unscrewing an oil filter using a belt; it can be inserted into a long head and transmit rotational motion to the head through a wrench, which will provide even greater unscrewing force. To insert the belt into the head, you need to make a slot on both sides with a grinder, into which the strap itself will be inserted.

To fix it, you can use a bolt, but if you do it very carefully and correctly calculate the width of the slot, then the timing belt can be held in it independently due to the teeth. More details about the manufacture of this equipment can be found in the video at the very bottom of this article.

You can insert the belt into a small square tube that will be used as a handle (lever). The released part of the belt is fixed by hand on a “square handle” or in another way (for example, hammering in a wedge), and then the filter is rolled up. But here we also need to take into account that there must be space around the filter.

You can also insert the belt into a closed (spanner) wrench and use it as a wrench to roll the filter from a dead point. This is quite simple to do, but you need to have free space around the filter.

https://www.youtube.com/watch?v=wpOE31kUnjQ

I assembled a video clip from the methods described above for unscrewing the filter using belts. They show more clearly the essence of the solution to the problem that has arisen. Removing the filter with a homemade chain puller Methods associated with reconciling the chain are somewhat more complicated, since, in fact, they require the creation of a more complex device than was used with a belt. Below I will talk about a couple of methods that are available for quick production of equipment, provided the materials are available.

You can take a bicycle chain and a piece of pipe, then drill a hole in the pipe for a bolt or any other object that will serve as a locking pin. The idea is as follows: we put the chain on the filter, insert the remainder into the pipe with the hole, slightly stretch the chain and insert into the hole on the pipe any fixing element that must pass between the chain links for fixation. Next, we apply force to unscrew the filter; the chain links dig into the body of the filter and does not slip even if the latter is stained with oil. You can learn more about the application of this method in this video.

On YouTube, I came across an excellent video on how to independently make pullers of several types from a belt and chain, but making them in a home-made environment will lead to a colossal amount of time, while the output can be obtained with suitable products.

I would also like to say that such factory-made devices are not so expensive and at home it is easier to use homemade devices with a belt or buy a ready-made filter puller.

The production of such pullers is relevant in a car service center, when there are free chains and heads that are no longer useful due to their wear or low quality.

How and with what can this be done?

We suggest you familiarize yourself with the main methods that will allow you to dismantle the filter device with your own hands.

User Andrey Florida in his video explained how to replace the oil filter and what options are available for dismantling it.

Can you twist it by hand?

There are special tools for dismantling the filter device. But you can also unscrew it yourself. If the sticking of the device is strong, a tool or improvised devices will be required for dismantling.

Which way should I unscrew?

The filter is dismantled by turning its housing counterclockwise.

Special key

You can use a special key to unscrew it. This is an effective method, but to implement it you will need to purchase a tool. You will find several key options on sale:

chain;
clamping tool;
tape;
screw puller.

How to use it correctly?

To unscrew it with a chain or other special wrench, hook the filter device with a tool, securely fix it and remove it by turning it counterclockwise.

Chain type dismantling tool

Special wrench with clamp for filter removal

Rope (belt) and screwdriver

To remove the device without a tool, use a belt or rope with a screwdriver:

A screwdriver is used to pierce the body of the filter device, as a result of which the tool is used as a lever. When using a screwdriver, you need to pierce the element right through, this will make twisting more effective.
When using a belt or rope, the dismantling method simulates the use of a special key. The strap should be wide and made of leather or leatherette. A loop is made, after which it is tightened on the device itself counterclockwise. For quick dismantling, give a sharp tug on the rope or strap. The removal process may be difficult due to the strap slipping. Then insert a piece of sandpaper into the loop itself and perform the described steps again.

Hammer and long screwdriver

This method of unscrewing a part is similar to the screwdriver method. Its implementation is relevant if you pierced the filter, but could not move it from its place. Then dismantling the device is possible by applying force from blows with a hammer to the screwdriver handle.

Hammer and chisel

If these dismantling methods do not help or the housing of the filter device is damaged, then use a chisel instead of a screwdriver. Make a small notch on the part for the chisel to rest against. We begin to hit the instrument with a hammer. This usually helps to quickly unscrew the filter.

Homemade instrument

You can change the filter and dismantle the device with a homemade puller. The operating principle of such a tool is identical to a special key.

You will learn about making your own dismantling tool from the video. The material was filmed and made public by the kv3st channel.

You need to build such a device yourself:

You will need a bicycle chain, or rather a section of it. When dismantling the filter in domestically produced VAZ cars, the optimal chain size is 30 links.
The chain is connected into a ring; a lock or rivet is used for fixation.
You will need an unnecessary head from a 19 or 22 socket wrench. You need to make a cut in it that matches the size of the bicycle chain.
Install the extension into the connecting square hole on the head. Use an awl or ratchet. For reliable fixation, the diameter of the extension must be equal to the size of the hole.
Unscrew the filter device by turning it counterclockwise.

Gas key

The use of this method is relevant if there is free space around the device. Hook the oil filter housing with the tool and use its handles as a lever. Be careful not to damage other powertrain components. Be careful as some oil will come out of the filter when removing it.

Replacement process

Replacing the oil filter on a Logan is carried out in several stages: the engine oil is drained, the gasket on the plug is changed and, accordingly, a new filter unit is installed. It is best to carry out the process on an overpass or pit so that you can freely climb under the hood. Operating time: no more than 15-25 minutes.

For repair you will need:

special puller;
container for used motor oil;
new oil element;
hammer and screwdriver;
key for 10 and key for 17;
key for the drain plug;
canister of suitable motor oil.

The location of the part on a Renault Logan car requires the observance of certain precautions: in particular, carry out repairs in overalls and gloves and do not touch other parts if the engine has been preheated.

The process of replacing the oil filter in Renault Logan:

Unscrew the bolts on the filter cover with a wrench;

Loosen the tightening on the drain plug;
place a container under the motor;
wait until the used lubricant is completely released;
Screw the plug tightly with a wrench and screw on the drain plug;
unscrew the old unit. It's better to use a puller. Before unscrewing, clean the attachment point;
We wipe the seat with a rag;
apply new grease to the sealing ring;
Fill the new unit with oil to the middle;
manually tighten the spare part;
pour 3.4 liters of liquid through the filler plug;
tighten the filler plug with a 17 mm wrench;
start the engine and check the special low pressure sensor;
inspect the work site and add lubricant if necessary.

In a short period of time, by performing the repair process, you can extend the life of the oil system on Renault Logan.

What to do next?

When the old filter is removed, before installing a new one in its place, be sure to wipe the mounting area with a rag, pour oil into the filter itself, and do not forget to lubricate the rubber gasket with it. Only after this can the new part be considered ready for installation. Screw it into place (you don’t need to put much effort into this), turn on the ignition and let the engine warm up, while you observe the repair site. If everything is done correctly, oil will not ooze out from under the filter.

Lubrication system for k4m and k7m (k7j) engines

In general, the lubrication system is designed like this: there is an oil pump, which is driven by the crankshaft (timing mechanism), and it transfers oil from the sump to the main line. The first part installed in the line is the oil filter - it needs to be changed periodically.

If there is insufficient oil pressure, the switch contact opens and then the indicator is activated. Parts that allow diagnostics include the control dipstick - it is immersed in the engine sump. On motors K4M and K7M, the dipstick is located at different points: in Fig. 1 it is designated by the number 5, in the second figure – by the number 7.

List of important elements:

Oil filler plug: element 7 (Fig. 1) and 1 (Fig. 2);
Drain plug: located at the bottom of the engine sump;
Oil filter housing: 19 and 6 respectively.

To unscrew the filter, you need a puller. If it is not there, a hole is made in the body closer to the bottom, and then an awl or screwdriver is used as a lever. The filter is dismantled after draining the oil. Before installing a new filter, on the contrary, it is filled with oil.

The drain plug is unscrewed with an 8 square. There will be a washer under the plug. A replacement is allowed - a copper washer with an internal diameter of 18 mm (advice from the magazine “Behind the Wheel”).

The original oil filter is suitable for all engines discussed here. Its number in the Renault catalog is 7700274177. Sellers, moreover, use the designation 7700274177FCR210134. And Renault has a filter 8200768913, which is also suitable. Good luck with your choice.

Method 1: Using a strong, sharp screwdriver and hammer

This is the simplest of all possible options.

The principle is as follows:

Take a large flat screwdriver and use it to punch a through hole in the filter housing (the metal is thin, so this can be done with almost one blow).
Next, you need to grab the handle of the screwdriver and apply force in a counterclockwise direction. Due to the increase in the force arm, the filter breaks off quite easily, after which it can be unscrewed by hand.

Please note that the oil can remain hot for a long time, so safety precautions must be observed.

Oil filter puller. how to do it yourself.

Using the Renault Logan car as an example, it is shown how to make a simple and convenient puller for unscrewing the oil filter in a hard-to-reach place, as well as the procedure for changing the oil.

On a Renault Logan car, the oil filter is located on the front of the engine in a recess, opposite which the generator is located.

You can, of course, do it in a simple way: pierce the filter on the side with a screwdriver and unscrew it. For example, as shown in the photo below. But the engine will be flooded with oil, which not everyone likes.

You can use an oil filter puller from older car models that have fairly easy access to the filter. But to do this, in this car model you will have to remove the protective cover of the exhaust manifolds.

By the way, in order to unscrew the nuts holding the casing on a warm engine, it is advisable to cool them a little with a wet cloth. It will come off much easier.

You can purchase an oil filter puller of a suitable design, but this is also not always possible. One option looks like this:

There is naturally one puller in the package, it’s just shown on both sides. Yes, and also, there is a mistake on the packaging, its diameter is not 46 mm but 76 mm. This has been mentioned on many forums. Such a puller is strictly tied to the size and design of the filter, and if they differ slightly, the puller will not work.

A universal puller for filters with a diameter of 62 to 102 mm can be purchased here at a very reasonable price. It looks like this:

After looking on the Internet for various options for homemade oil filter pullers, I came up with the idea of making my own design. It does not require scarce materials and is quite simple to manufacture. You will need a metal strip with a width of 20 to 50 mm, a length of about 250 mm and a thickness of about 1 mm.

The edges of the strip need to be bent and two handles made of a rod about 10 mm in diameter and 20 mm long must be welded at an angle. If there is no welding, you can attach the handles with screws, having first made slits in the rods with a hacksaw or slightly flatten them with a hammer on the edges that will be attached to the strip. That's all.

The fourth method is a hammer and chisel

Another fairly simple way to unscrew the oil filter without a key. To do this, we don’t need anything else except the chisel itself with a sharpened tip and a hammer. How we do it:

Place the sharp end of the chisel on the rim of the filter bowl on the side adjacent to the engine.
We position it at such an angle that at the moment of impact it could tear off the oil filter, that is, counterclockwise.
We hit the chisel with a hammer. Didn't it break? We move the chisel a centimeter further and hit again.

Eventually the filter will turn and the part can be turned out by hand. If anything remains unclear, watch the video.
