How to replace the air filter on a Ford Focus 2: effective methods and detailed instructions

It’s easier to work here than when replacing the Focus 2 dorestyle air filter. As already mentioned, replacing the air filter yourself is not difficult for any car owner. You need to prepare the necessary tools and the filter itself in advance. If we change the air filter, the following tools will be required:

So how do you replace the air filter? First, use a 7mm head to unscrew all 4 mounting bolts. Make sure that the bolts remain in their fastening places, otherwise it will be difficult to put them in place when reinstalling.

When to change and which air filter to install on Ford Focus 2

• Then, unscrew the two mounting bolts of the air duct and disconnect the pipe so that it does not interfere with the removal of the old filter and installation of the new one.

• We will also replace the crankcase ventilation filter in one go.

• Now, install the new filter, make sure that it sits exactly in place in the neck.

After dismantling the filter, assess its condition. If you have followed the recommended interval, and it looks quite dirty on the outside, then you should change the replacement interval. And then the question of how long to change the air filter at the focus will disappear.

Now all that remains is to screw on the pipe and the air filter cover.

An important note is that the driver should not be tempted to blow out the old filter using a compressor and continue to use it. Such purging is practically used in cases of temporary operation of a car in difficult conditions, but if the filter has not yet exhausted its service life.

Before reinstallation, it is necessary to lubricate the seat, the inner ring of the cylinder, using WD-40 lubricant to avoid the application of excessive physical force and not damage the filter. You should put the filter on, turning it slightly, and make sure that the housing fits neatly into the required grooves.

You should tighten the mounting bolts only after you are sure that the cover is firmly in place.

A little trick for an experienced driver is to mark the installation site with a special label where you can record the date and mileage at which the replacement occurred.

It's no secret that if you don't do this, in a year you will only have vague memories of the replacement date.

Replacing the air filter for Ford Focus 2. Photos, instructions on how to change the air filter on Focus 2

Replacing the air filter of a Ford Focus 2 (2009, 1.6 engine, petrol) is a completely routine routine maintenance procedure. You can easily change the air filter yourself. In this case, the original one was replaced with a Simota OFO-010 sports filter.

The frequency of replacing the air filter, which is indicated by the maintenance regulations, is 20,000 km. In severe conditions, it is recommended to check the filter earlier (for example, at 15,000) and clean it or even change it if it is heavily soiled.

In this case, the original one was replaced with a Simota OFO-010 sports filter. Sports air filters are much more expensive than regular ones, but they are of better quality and last longer. They can be washed.

How to change the air filter Ford Focus 2

Replacing the Focus 2 1.6 cylindrical air filter is ridiculously simple. You need to unscrew the 4 bolts around the perimeter of the air filter housing, remove the cover and pull out the filter.

After this, you can inspect the air filter to determine whether it can be cleaned or whether it is better to get a new one . You should also check the housing, perhaps it also needs to be blown out of dust.

Installing a new cylinder air filter is done in the reverse order.

Unscrew the 4 bolts securing the air filter housing cover.

Resonator installation

• use a head wrench to unscrew the mounting bolts - in the direction of the upper radiator transverse frame;
• dismantling the resonator with the air filter housing and muffler - it is necessary to remove the part pipe from the housing;
• Use a head wrench to loosen the air duct mounting clamp and remove the crankcase hose along with the pipe.

Replacing the air filter Ford Focus 2

Since all cars have already expired from warranty, their owners either trust private services that are cheaper than the official ones, and perform many operations themselves.

One of the simplest is replacing the air filter; Ford Focus 2 does not present any difficulties in this regard, and the work does not take up too much time.

Cars of this family were equipped with two types of filters, which were fundamentally different from each other: pre-restyling cars mostly used a compact rectangular filter, which showed an extremely short resource - the 15 thousand kilometers between maintenance declared by the manufacturer were rarely maintained even in average urban conditions, not to mention dusty ones. country roads. Therefore, on most cars, the filter was replaced with a cylindrical one, with a much larger area - for Germany these are cars produced after the end of March 2007, for the Russian assembly - from May 2007 (some cars with a 1.4 engine received old filters until January 2008). After updating the body in 2008, accordingly, all cars were equipped with only cylindrical filters.

Choosing an air filter for Ford Focus 2

Considering the small area of ​​the filter element, it is worth reducing the replacement interval to at least 10 thousand, especially on cars with the largest engine capacity in the series.

The updated cylindrical filter has article number 1708877 (later replaced by the manufacturer with 1848220).

It, like the previous one, was produced by the Mahle concern (non-original - LX1780/3), but there is an unexpected design difference between these filters: the Mahle filter has a small protrusion that makes it easier to center it in the box (the protrusion engages with the groove), The “original” is missing on many cars.

The replacement procedure for cars with “old” and “new” filters is slightly different.

On vehicles with a rectangular filter, the air flow sensor is mounted directly on the filter cover. The simplest dismantling option is to remove the connector from the sensor (the ignition must be turned off!), after which the clamp of the rubber corrugation of the air duct is loosened.

Next, the screws (with a bat or a T25 screwdriver) located around the perimeter of the cover are unscrewed, and it rises to the top. The filter itself can be removed without special precautions, since its air intake is at the bottom, and dirt does not enter the intake manifold when removing the filter.

• The new filter is placed in place, and for a tight fit it is advisable to clean the perimeter of the box into which the seal rests.

• Next, the cover is put in place (the screws are tightened crosswise with a little force so as not to deform the plastic), the corrugation is put on the air flow sensor, and the connector is returned to its place.

Assembly

After replacing the coarse filter and the pump itself, you should check the tightness of the wire chip. The glass itself should be securely in place. Next, the element is installed in the tank. Previously disconnected tubes are connected to it. And here the problem arises - how to close the lid? The lid was cut out independently, so we need to figure out how to seal it as tightly as possible. To do this, you can take a plate measuring 30x30 cm and drill holes in the corners with a drill.

Next, we finally cut off the old cover and place the plate on the hole. We will need to drill a couple of holes in the body itself. Then a thread of the appropriate diameter is cut with a tap and the bolts are installed. To fasten the plate, it is enough to use an 8 or 10 mm bolt

When choosing the depth of the hole, it is important not to overdo it, otherwise you may drill through the tank itself. Moreover, this will happen unnoticed, because it is made of plastic, so choose the bolts as short as possible

Replacing the air filter on a Ford Focus 2 with your own hands

Hi all! Today at Ford Master we will talk about how to replace the air filter on a second generation Focus. We have already provided you with reports on how to replace the air filter on a Fusion; we also talked about how to replace this element on a third-generation Ford Fiesta and Mondeo. Today it’s the turn of the Focus... The work is not difficult, as in all of the above cases, everything is done simply and without any problems. The main thing is to have some tools for the job, namely: a screwdriver; a ratchet with an extension and several heads, a new filter, and about half an hour of time, and of course the insatiable desire to do the replacement yourself.

When to change the air filter?

According to the regulations, the air filter should be replaced after approximately 20 thousand kilometers. If you live outside the city or drive on dirty, dusty roads, then from replacement to replacement you should not have more than 10-15 thousand km.

In the interval between replacements, it is recommended to monitor the condition of the filter and the degree of its contamination; if you find mechanical damage, deformation, accumulation of large amounts of dust, sand or other foreign debris on the filter, you should replace it early to avoid all of the above from entering the engine.

Step-by-step photo report on how to replace the air filter on a Ford Focus 2

So, if you have everything you need, you can get to work.

1. We turn off the engine, let it cool, then lift the hood.

1. Using the “7” socket, unscrew the 4 bolts securing the housing cover under which the filter itself is located.

1. Next, take a ratchet, a small extension and proceed to unscrew the two right screws located on the right

1. Pull the housing cover towards you and set it aside. Under it you will see an old, unusable filter, which we will actually change.

1. Using a TORX T-25 wrench (asterisk), unscrew the two screws marked in the photo; they secure the air duct. We do this in order to simplify the process of dismantling the old and installing a new filter. If there is no “star”, use the “8” head.

1. Next, move the pipe aside and take out the old filter. We assess its condition, take out a new filter and install it in place of the old one. Before installation, I recommend vacuuming out dust and sand in the air blower housing, if there is any. It also doesn’t hurt to check the condition of the crankcase gas filter, which is a small piece of foam rubber. In my case, this “filter” turned out to be dirty, so there were two options: either wash the old one or cut out a new one. I chose the first option.

1. Assembly is performed in reverse order.

The work is done, all that remains is to assemble the tool and test run the motor. As you understand, there is no point in entrusting such work to service station workers, since it is uncomplicated and can be easily done with your own hands, and besides, such “amateur work” will ultimately save time and money.

Compression check

After checking the compression, you can breathe a sigh of relief or worry, since the cost of the repair depends on the result.

Impaired compression often causes the presence of oil in the VF, and also causes a number of other problems.

Compression check

To work you will need:

• Compressometer;
• A rag in oil, which you will use to determine the compression stroke;
• Adapter for spark plug holes. It is used when checking the combustion chamber for leaks;
• Compressor.

Now let's start checking.

1. Warm up the engine to operating temperature, then turn off the fuel supply.
2. In the case of a carburetor, you need to remove the hose, clamp or squeeze it with something, or lower it into a container.
3. If you have an injector, remove the fuel pump fuse, start the engine and let it run. As soon as the fuel in the fuel rail runs out, it will stall on its own.
4. Disconnect the ignition system by removing the center wire from the distributor (on the carburetor). The crankshaft position sensor at the injector must be disconnected.
5. Remove all debris from the spark plug wells so that it does not end up inside the cylinders. Unscrew the spark plugs.
6. Insert the compression gauge fitting while an assistant starts the engine. The starter should rotate the engine until the pressure gauge needle stops in one position.
7. By analogy, measurements are carried out on each cylinder, the results are recorded on paper.
8. To calculate ideal compression, use the formula - 1.2 * Compression ratio.

See your owner's manual for the compression ratio of your engine. Please also note that measurements may have some error.

What you need to know about verification

1. If the indicator is 12 atmospheres, this indicates that your engine is almost in perfect condition.
2. When checking the compression on a cold engine, the compression readings will be significantly lower. Perform the test only on the engine at operating temperature.
3. If the battery is partially discharged, the test data will also not be accurate.
4. The increase in compression occurs due to the combustion of oil in the cylinders.

What the results say

We take the paper where you wrote down the data of the check, carried out according to all the rules, and study what is wrong with the motor.

1. Indicators in the range of 0-4 atm indicate a high probability of burnout of the piston, head gasket or valve.
2. Compression of 4-6 atmospheres indicates that the piston rings or the partition between them have broken.
3. If you get about 8-10 atm in each cylinder, the cylinder-piston group is worn out. Major repairs will soon have to be carried out.
4. 12-12.5 atm - these are the indicators that occur in a new, run-in power unit.
5. If the car has serious mileage, and the check data shows numbers equal to or exceeding the norm, oil has probably entered the cylinders due to wear of the cylinder-piston group or valve liners.

Obviously, the presence of oil in the filter does not bode well. But the problem can still be prevented if measures are taken in time.

How to replace the air filter on a Ford Focus 2

As you know, the Ford Focus 2 air filter serves to filter and clean the air flow from external contaminants and exhaust gases entering the car engine.

Therefore, replacing it is a priority during car maintenance or when the filter fails.

Today you will learn about what kind of air filter is needed in a Focus 2 car, and what types there are, as well as how to change the cleaning element.

A Ford Focus 2 may have one of several types of filters installed, depending on the version of the vehicle, so its choice depends solely on the vehicle.

In particular, the standard air purification element for Ford Focus 2 in a rectangular housing is a traditional filter that is installed on most cars. Its cost is not cheap: 500 - 1000 rubles (150-300 hryvnia), but it is publicly available and is sold in any car store.

New filter element for the restyled Ford Focus 2

As for the restyled version of the “second” Focuses, in them the air purification is carried out by a cylindrical element. Such cleaning components have been installed on manufactured cars since 2007. In the period from 2004 to 2007, pre-restyling version cars were equipped with a flat paper filter in a rectangular housing.

Subsequently, the manufacturing company decided to install purifiers in their vehicles in this particular housing and shape. Cylindrical elements were considered more inconvenient due to their excessively large filter surface and considerable size.

Below is the average cost of an air component depending on engine type:

• 1.4 liter engine - 600 rubles (200 hryvnia);
• 1.6l and 1.8l engines - from 500 to 900 rubles (150 - 250 hryvnia);
• 1.8 liter diesel engine - from 350 to 700 rubles (100 - 200 hryvnia);
• 2l engine - from 400 to 1000 rubles (120 - 270 hryvnia).

One way or another, it is better to replace the element with the original one.

The manufacturer recommends that owners of restyled Ford Focus 2 cars change the air filter element every 20 thousand km..

But the service life of the working element is significantly reduced if the vehicle is operated on roads with high dust levels. Therefore, it is better to change the air filter (hereinafter referred to as the air filter) every 10-15 thousand km.

Replacement process

Replacing the air cleaning component in the restyled Ford Focus 2 itself is not a labor-intensive task, so even the most inexperienced driver can cope with it. The main thing is to follow the instructions provided and carry out all the steps exactly.

If you replace the cleaning element in a timely manner, you will get the following results:

• the engine's operating life increases;
• the vehicle's power increases while driving;
• normal operation of the exhaust system;
• saving gasoline.

Tools

The manufacturer recommends replacing the air component together with a crankcase gas cleaner. Therefore, we will consider the process together with the change of this part. Before you begin the actual replacement, prepare everything you might need:

• a wrench or a socket wrench with an extension to “7”;
• the air filter itself (the brand of the original element is Mahle LX 1780);
• rags;
• new crankcase gas filter;
• liquid VD-40;
• Phillips screwdriver.

Replacing the air filter Ford Focus 2 —

Although the last Ford Focus 2 rolled off the production line 6 years ago, this model continues to remain popular on the market. Naturally, all cars of this generation are already out of dealer warranty, so the question is “where to service the car?” always relevant for their owners.

Fortunately, the design of the car allows you to carry out many routine maintenance work yourself without any problems: for example, by replacing the air filter on a Ford Focus 2 yourself, the owner will spend only a few minutes.

How often should I replace it?

First, let’s decide which filter to talk about: cars in the first years of production used a compact flat filter, which, according to reviews from owners, did not prove to be the best, especially on 2.0-liter engines.

Although the manufacturer set the replacement interval at 15 thousand, even under average conditions, without getting carried away with driving on dirt roads, the owner could feel a noticeable deterioration in engine thrust even before the next maintenance.

Therefore, cars that rolled off the assembly line after May 2007 received an updated cylindrical filter with a much larger area (for the Russian assembly, the update affected primarily engines from 1.6, some cars with 1.4 engines continued to be equipped with old filters). The new filter is guaranteed to last the stated 15 thousand, exceptions are possible only with constant driving on primers.

Air filter selection

The air filter on pre-restyling cars had a factory part number 1232496. In fact, the Knecht/Mahle LX1572 filter was used on the assembly line, supplied directly in Ford OEM packaging, so this analogue can be considered absolute.

Also among non-original substitutes we can point to Bosch 1 457 433 323, MANN C 28 122, Champion U 793/606. Since the filter life is short due to the selected size, more frequent replacement of the Ford Focus 2 air filter with a non-original one is significantly more profitable than using the original.

After restyling, a filter with article number 1708877 began to be used (on cars of recent years, article number 1848220 can be selected by VIN).

This filter was also produced for the Ford assembly line by the Mahle concern (their catalog number is LX1780/3), its other analogues are Bosch F 0264 001 36, MANN C 16134/1, Fram CA 10521. All these filters perfectly withstand 15 thousand runs, and only on very dusty roads they manage to significantly reduce their throughput.

Instructions for replacing the air filter on a Ford Focus 2

Replacing the air filter with your own hands does not take much time and does not require the purchase of special tools for both pre-restyling and post-restyling cars, although the procedure itself is somewhat different for them.

On pre-restyling versions, the air flow sensor was rigidly attached to the filter cover itself. Therefore, for convenience, it is best to remove the connector chip from the sensor, having first turned off the ignition, then loosen the air duct clamp and pull off its corrugation from the MAF outlet pipe.

Then you can remove the screws around the perimeter of the air filter cover (head size – Torx 25). There is no need to take any precautions when removing the filter, since all the dirt from it will fall down to the air intake and cannot accidentally enter the intake manifold.

Before putting the new filter in place, it is worth wiping the perimeter of the box with a damp cloth to remove dust and ensure a good fit of the seal.

Having placed the filter, we carefully tighten the screws securing the cover crosswise (the plastic is fragile, and there is no point in overtightening them), place a rubber corrugation on the MAF pipe and tighten the clamp for its fastening, after which all that remains is to connect the MAF connector.

• On updated cars, everything is even simpler: using a small ratchet with a “7” head and an extension, you need to remove the four screws located around the perimeter of the filter housing cover, and then simply lift the cover up.

• Lifting the filter by the right edge, we pull its neck off the protrusion on the air duct, which centers the filter in place.

Now you can install the new filter. In this case, the main thing is to settle it on the protrusion of the air duct without distortions, which can lead to the suction of unfiltered air into the intake.

The main inconvenience in this case is associated with the low rigidity of the filter housing - the plastic “walks” in your hands, which is especially noticeable when installing the cover.

It stretches in exactly the same way as on the pre-restyling version - crosswise, without making much effort.

Procedure for replacing the air filter on a Ford Focus 2

A Ford Focus car needs a scheduled replacement of the air filter during operation. If you neglect the procedure and do not carry out maintenance in a timely manner, the following problems may arise:

• reduction in the working life of the Ford Focus engine;
• reduction in power unit power;
• increased fuel consumption;
• malfunction of the Ford Focus exhaust system.

Installing a new air filter

It is possible to change the consumable element yourself, simultaneously installing a new crankcase gas purification system and a resonator that separates air flows and dampens engine noise. Tools and materials

Fuel consumption, engine power

Filtration device in a carburetor car

The air filter in a car affects the rate of fuel combustion inside the engine and, as a result, the engine power. Complete combustion of a combustible mixture is possible provided that it contains about 20 times more air than fuel. The car takes air from the environment, so the air flow contains dust, insect particles, plant spores, and so on. All these harmful impurities, once inside the engine, act as abrasive particles and lead to disruption of the power unit. The purpose of the filter device is to clean the incoming air from harmful impurities of dust and dirt. Passing through it, the air is purified, then mixed with fuel and leads to complete combustion of the fuel due to the presence of a large amount of oxygen in its volume, helping to reduce fuel consumption.

This device also affects the power of the motor due to the resistance created by the incoming air. The filter element can have a different design and, depending on the number of filtration layers, provide resistance to the flow of incoming air. As resistance increases, engine power decreases, as the amount of oxygen entering the engine decreases and the fuel does not burn completely. Replacing a worn-out filtration device with a new one will help reduce fuel consumption.

An increase in power on sports cars can be achieved by installing filter devices with zero resistance. Such filters consist of a minimum of layers treated with a special adhesive to trap small particles. “Nuleviki” do not create additional loads on the engine and allow you to achieve maximum engine power.

How to change the Ford Focus 2 air filter

Ford Focus car engines are highly reliable, but only if the car is regularly serviced.

The Ford Focus 2 air filter must be replaced in a timely manner - when the filter element and the engine become clogged, various problems arise. In this article we will look at how to change the air filter and how often it should be replaced.

Ford Focus 2nd generation cars

The Ford Focus brand itself has been produced since 1998, and in 2004 the production of Ford Focus 2 started. Dorestayl is a model that was produced in 2004-2008, Focus was restyled in 2008, the car underwent changes:

• front bumper;
• optics;
• front wings;
• radiator grille.

The Ford Focus-2 car for Russia was equipped with various engines, both gasoline and diesel; in total, seven types of power units were installed on the Focus.

Gasoline internal combustion engines are Duratec, with a chain drive of the gas distribution mechanism, and Zetec, with a timing belt drive, with a volume from 1400 to 2000 cm3. Also in the range of engines is the Duratorq 1 diesel engine.

Replacing the air filter Ford Focus 2

On second-generation Focus vehicles, the engine air filter (AF) is changed during maintenance; the cost of replacement is included in the general list of maintenance services.

According to the regulations for replacing the filter element, many sources indicate different data; in general, it is recommended to change the VF on Ford cars through one service. If each maintenance is carried out every 20 thousand.

kilometers, it turns out that the air filter needs to be updated once every 40 thousand km.

This replacement frequency is suitable for an environmentally friendly environment; perhaps the regulation is observed in Europe or America. In Russian conditions, the air filter becomes dirty much faster, so the Ford Focus 2 air filter should be replaced more often, after 20 thousand, and in conditions of heavy dust - after 15 thousand km.

The importance of timely replacement of the air filter

The air filter element in the engine must be changed regularly; if the air filter becomes clogged, various problems arise with the engine:

• air does not pass through the filter well, so the proportion of the fuel-air mixture is disrupted, the engine loses power and does not develop speed;
• dust and dirt from the filter penetrate into the internal combustion engine cylinder, premature wear of the piston group occurs, and the life of the engine is noticeably reduced.

Replacing the filter yourself

Maintenance at a car service center is not very cheap, so many car owners, in order to reduce costs, carry out maintenance themselves. It’s not difficult to replace the filter with your own hands, let’s look at how to change the engine filter element on a pre-restyling Focus-2 car with a 1600 cc engine? ZETEC. We carry out the work as follows:

• turn off the engine, open the hood;
• pull off the plug from the air flow sensor;
• unscrew the clamps of the injector pipe, disconnect the corrugation from the VF housing;
• unscrew the screws of the top cover of the VF housing, there are six of them in total, remove the cover;
• remove the filter element itself from the housing;
• if dirt and dust have accumulated in the lower part of the case, the plastic box should be removed in order to wash it;
• There is a sponge inside the lower housing at the bottom left; if it is dirty, it also needs to be changed;
• Having cleaned the body of dirt, install a sponge filter, secure the plastic box in its place;
• install a new filter element;
• fasten the top plastic cover with self-tapping screws;
• We put the pipe (corrugation) in place and connect the mass air flow sensor plug.

Replacing the filter element Focus-2 restyling

On the restyled version of Focus 2 with a 2.0 Duratec engine, a cylindrical filter element is installed, and is it mounted differently than on a 1600 cm3 internal combustion engine? Zetec dorestyl. Replacing VF Focus-2 restyling is extremely simple; we carry out the work as follows:

• unscrew the 4 self-tapping bolts securing the VF housing cover, they can be unscrewed with a 7 mm wrench;
• remove the top cover;
• bend the part of the lower housing with the pipe by hand and remove the filter element;
• We wipe the lower part of the body from dirt if it has accumulated there;
• We put another filter element in place, close the top cover, and tighten the screws.

The whole job takes literally fifteen minutes, and such a replacement can be made by any driver who does not have any plumbing skills. In some cases, the cylindrical filter does not fit well with the dimensions of the housing, but, as a rule, this happens with “non-original” ones; no problems arise with original spare parts.
