VAZ 2114 pump signs of malfunction 8 valves injector

Signs and causes of pump malfunction on a VAZ-2114

None So, let's look at the signs of a malfunction of this node in more detail:

Belt whistle . When the belt begins to whistle, this may not only be a signal to replace it, but also mean that the internal bearing of the product begins to wear out and becomes unusable. So, you can remove the assembly and replace only this part.
Leaks from the gasket . Wear of the gasket and small drops from under it also signal a future malfunction and failure. So, it is worth replacing the gasket itself.
Product backlash without whistling . A bearing failure or a broken water pump shaft seat can cause this effect. So, you can feel it by slightly shaking the shaft. Here, the only correct solution would be to replace the product, since a new bearing will not eliminate the play on the product itself.

Part of the process of removing the pump from the car Now that the main causes have been discussed, we can turn to the issue of signs of malfunction:

A coolant leak

Traces of smudges are clearly visible

How to check the cooling system pump?

By checking the pump without removing it from the engine, we can only indirectly assess its performance. When the volume of pumped coolant decreases, the stove begins to heat poorly. But before removing the water pump to inspect the impeller, we recommend checking the thermostat and also making sure that there is no air lock in the cooling system.

After removal, pay attention not only to the integrity of the blades and where the impeller fits on the drive shaft, but also to the shape of the blades. For example, on the VAZ 2121 over many years of production, impellers were installed that differed in the diameter of the pump wheel, the number and profile of the blades. Installing a less efficient pump on a more heat-loaded engine modification will result in the cooling system fan turning on more frequently and an increased risk of overheating.

Be sure to inspect the engine block where the housing fits and the pump itself. Fogging or a slight leak of coolant from the drain hole does not mean that the pump should be replaced. If a significant leak is detected, try to pinpoint the location of the leak. If the leak is only at the junction of the housing and the engine block, most likely the problem can be eliminated without replacing the pump. It will be enough to apply sealant and install a new gasket.

Elimination methods

There are several ways to troubleshoot the problem. So, we can consider the main ones:

The easiest option is to replace the water pump assembly . Thus, the element is completely replaced, which normalizes the operation of the power unit.
Replacing the pump bearing . Of course, not the easiest option, but relatively cheap. The only difficulty will be to disassemble the water pump.
The gasket is replaced in cases where it is necessary to replace only this element if a breakdown or wear has occurred.

conclusions

If traces of scale are visible on the pump, then the cooling system must be flushed urgently. All the causes and signs of malfunction of the VAZ-2114 water pump are considered, and the motorist, knowing this information, can easily prevent the failure of the unit on the road, as well as replace the element prematurely. Of course, if it is not possible to determine the condition of the unit yourself, then it is recommended to contact a car service for diagnostics.

The pump is a spare part of the invisible front. It works in the bowels of the engine, ensuring its cooling, and the results of its work are visible only by the arrow reading on the coolant temperature indicator. The pump is also insidious, it is a relatively inexpensive spare part (although the price depends on the specific car model, some are expensive), but changing it is expensive, because for this you have to disassemble a lot. This is especially felt on cars with a timing belt drive, because most often in such cars the timing belt turns the pump. But even in those cars where the drive is a separate belt, there is still a lot of hassle in replacing the water pump.

On the left is the old, on the right is the new engine water pump. This feature has developed a certain rule among reasonable drivers - it is better to change the pump at the same time during large-scale maintenance or other work (most often this is replacing the timing belt) than to then change the water pump separately. The cost of replacing a pump with the timing drive removed is an order of magnitude cheaper than separate work to replace only the pump. Some drivers prefer to generally change the pump every time the belt is changed (for example, once every 60-80 thousand kilometers), but this seems like overkill. The service life of a pump is an unpredictable thing, it depends on the specific model, proper operation (pumps really do not like other types of antifreeze, as well as various mixtures) and simple luck. Even on the same car model, pumps fail at different mileages, literally from tens to hundreds of thousands of kilometers.

In order not to overpay and not change a part that can still serve and serve, we would suggest adhering to the following algorithm: with every serious disassembly of the gas distribution system or other large-scale work in the pump area, be sure to check its condition. If there is even the slightest sign of malfunction, then replace the pump preventively. Yes, maybe it would still serve, but the fact that it would last until the next large-scale work is no longer a fact. If there are no questions about the water pump, then you can let it work for another period.

Part price

The water pump for 2114 is produced by many Russian and foreign manufacturers. In addition to AvtoVAZ products, spare parts from the brands Luzar, TZA and Gates are popular among owners of this car. Parts from other brands are also available for sale. Their prices vary:

"AvtoVAZ" - 925 - 1170 rubles.
"BelMag" - 750 rubles.
KRAFT – 945-1055 rubles.
TZA - 1480-1760 rubles.
Luzar – 920 rubles.
Valeo - 1880 rubles.

The most durable, according to the majority of owners of the fourteenth, are considered to be branded products of the automaker, TZA and Luzar products. They demonstrate the optimal combination of price and quality.

Engine overheating

With a normally operating pump, the coolant temperature can only reach the red zone in the summer when parked for a long time at idle or driving at high speeds. If the needle approaches 105 degrees while driving, this may indicate a pump malfunction. It’s easy to check - just turn on the stove. If it blows cold air, there is no coolant circulation in the system. The water pump needs to be replaced. The most common cause of pump failure is a broken impeller.

Typical breakdowns

It happens that the stove on a VAZ 2110 does not heat well, does not allow you to fully control it, and so on. Let's look at the most typical breakdowns for this unit.

The ability to control is lost, that is, the temperature of the stove on the VAZ 2110 is not regulated;
The ceiling sensor refuses to work;
The device does not work for heating, the stove blows cold air into your VAZ 2110;
The flow of hot air to the feet or to the side windows is poor;
The coolant level drops;
The heater fan on the VAZ 2110 does not work properly;
The stove turns on and heats up, but this is accompanied by a lot of noise.

DIY pump replacement

Removing the VAZ 2114 pump The replacement process depends on how many valves there are in the car’s engine. An 8-valve engine has one crankshaft pulley, a 16-valve engine has two, therefore the system is organized differently. By the way, a pump for an 8-valve engine will not work for a 16-valve engine and vice versa.

If the sign of a pump malfunction is the timing belt wear, then you need to check the condition of the tensioner roller. If there are signs of rust, it is better to change it too. If there is no lubricant under the sealing rubber, or there is not enough lubricant, the supply must be replenished.

It is also worth checking what degree of wear the alternator belt has. Although its unexpected break is not critical for the car, changing the belt on the road is a dubious pleasure, especially if there is no spare one.

If you're unlucky

A less good outcome is, unfortunately, more likely. If the hood on your VAZ-2114, VAZ-2115 or VAZ-2109 does not open and you cannot feel its edge from the passenger compartment, you will have to drive onto a pit or overpass. Some dismantling work will have to be done.

Unscrew the engine protection. It is secured with several bolts, and you will need a 10mm wrench. And then reach with your hand between the engine and the radiator towards the hood. The opening mechanism must be moved towards the driver's door. Ideally, someone should help you, because in normal conditions this mechanism will be more difficult to open. If someone or something presses down on the hood, you will be able to open it much easier.

After sliding the mount, fold it back and fix it. If this is not done, it may well slam shut and you will have to crawl under the car again. As we wrote above, start repairs as soon as possible, so that you don’t have to do this procedure every time you need to check the oil due to a broken cable.

As practice shows, the hood opening cable on the VAZ-2115, VAZ-2114 and VAZ-2109 can break for a number of reasons, the main one of which is temperature changes. The steel wire used for it is very sensitive to kinks, and again it does not become stronger due to defrosting/freezing cycles.

To prevent a similar breakdown in the future, we recommend using a braided wire cable. In such conditions it shows itself to be stronger and more durable. And you will definitely stop having headaches about this if you choose the option of a cable with a casing. It will smooth out temperature changes and ensure uninterrupted operation.

After replacement, the hood will open and close with some effort for some time. This is a normal situation; it takes some time to “grind in” the parts and after a few weeks

Replacement process on an 8-valve VAZ 2114

Remove the timing belt protective cover.
Loosen and remove (if necessary) the tension roller.
Loosen the generator, remove the generator and timing belts.
Disconnect the hoses from the pump and drain the coolant.
Remove the protective cover and pump.

After removal, you need to thoroughly clean the surfaces of the pump flange and cylinder block from dirt and stuck gasket residues. The growth of a mud “beard” is one of the reasons for the pump being skewed and the timing belt being eaten away.

To avoid leaks, the gasket must be thoroughly coated on both sides with red sealant. After replacing the pump, it is necessary to set the timing marks: the crankshaft may move relative to the camshaft.

We recommend: Do-it-yourself modification and modernization of the stove on a VAZ 2114

The history of the VAZ 2114 brand “tells” us that the presented model is a copy of the famous “nine”, however, a slight inaccuracy is allowed: the base for this model was 21093, which became the most successful modification of the “exclusive” car. Similarly, like the entire Samara 2 series, this model absorbed a number of changes that affected the design of the car and some important components.

This example from the popular “family” received a more streamlined exterior compared to model 21093. This design element creates an interesting effect - the main roots of the debut Lada Samara series are difficult to discern.

Replacement process on a 16-valve VAZ 2114

On 16-valve cars, changing the pump yourself is more difficult, but it is also quite possible.

Remove the plastic cover and timing belt cover.
To remove the casing that separates the pulleys from the cylinder block, you need to remove the timing belt, camshaft pulleys, tension and support rollers. Without this, you will not be able to remove the pump.
To get to the lower housing bolts, you need to remove the right wheel.
Remove the pump.

Further actions are identical in content to cars with an 8-valve engine.

When replacing a pump, it is important to follow the installation technology. An incorrectly installed pump will leak, just like the old one. In the same way, it can eat the timing belt. There can be many reasons for motor overheating, and if replacing the pump does not help solve this problem, it is worth reading the corresponding article on the website.

The pump allows you to ensure efficient and proper operation of the entire cooling system. In the case of the VAZ 2114, the pump operates due to movements from the timing belt and is connected to the generator pulley. Since a lot depends on this unit, you should constantly monitor its condition and make prompt decisions in case of malfunctions.

Ways to open the hood if the cable breaks

Replacing the timing belt and pump on a Prior
The design of the hood, lock and location of the cable drive on cars are different. But the repair sequence remains the same in all cases. Owners of domestic brands are luckier, since manufacturers have not made significant changes to the design of cars produced over many years. Therefore, you can always open the hood without any problems.

Most often, the cable breaks near the lever, less often under the hood. In the first case, it is easy to deal with the breakdown, but in the second you will have to tinker.

When the cable breaks in front of the lever

This is the simplest situation. To eliminate the breakdown, inspect the place inside the car where the cable and the hood opening handle are attached; the stopper may have fallen off the lever - insert it into place and secure it. If you notice that the cable itself has broken off, then you will need pliers. To open the hood, try to firmly grasp the cable together with the casing and pull down. It may not work the first time. If a breakdown occurs, cut the hood and wrap the metal cable around the pliers, and then pull with great force - the hood will open.

When the cable broke under the hood

If you examined the fastening inside the cabin and found nothing, it means that the cable broke off under the hood near the lock. This problem is considered the most serious, because you need to somehow gain access to the lock and forcefully release it.

For a rear-opening hood, there are two main methods that can be used in domestic and foreign cars.

Through the radiator grille.
On many models, you can reach the lock using a homemade wire hook or knitting needle. Insert the hook into the slot in the radiator grille. You can also climb through the air intake. Reach the tab to which the cable is attached and pull it. Some cars have a solid grille with no slots. In this case, it needs to be removed, but this is not always easy. In extreme cases, you will have to break it. A new grille is inexpensive.
Through the crankcase protection.
This is another way that will help you get to the castle. You will need an inspection hole, but if there is none, you will have to repair it lying on the ground, jacking up the car. Remove the metal protection of the engine oil pan. Using a long screwdriver, reach the tongue to which the cable is attached and press to the left (towards the driver). You may need help from another person. You pull the cable, and the assistant first presses the hood down, then lifts it up.

If the hood opens forward, in this case you will have to tinker. You will need a homemade hook. You can get to the lock through the hood air intake. Remove it and grab the cable through the grille. In some cases, it is necessary to cut out one division, since narrow slots make it difficult to complete the work.

If you can’t open it, then another method will help you. Lift the edge of the hood near the lock. Pull out the rubber seal and there should be a gap. Then use a long screwdriver or hook to hook the cable and the hood will open.

VAZ pump malfunctions

Like any other mechanism of the VAZ 2114 car, the pump tends to break. Its breakdown can be determined by a number of characteristic signs. The first of which is a coolant leak from the system.

This happens when the oil seal wears out. It begins to leak liquid and gradually collapses. Of course, not only the oil seal can cause a coolant leak, but also the radiator or pipes.

The second symptom of a faulty VAZ 2114 pump is that antifreeze or antifreeze circulates poorly and the engine overheats. The cause of this breakdown may lie in the impeller. If it is worn out or damaged, then the circulation of the fluid deteriorates significantly, and as a result, the engine does not have time to cool down.

In order to check this part, it is necessary to remove the pump from the engine and inspect it from the inside. Basically, if the impeller is broken, it will be visually noticeable.

The last symptom of a pump failure in a VAZ 2114 car is a strong howl in the area of the pump, which is heard during engine operation and intensifies at high crankshaft speeds. This indicates that the bearings on the shaft are worn out and require urgent replacement. This often happens in conjunction with a broken oil seal, since it is this that often causes rapid wear of the bearings.

Coolant leaking

This problem can occur after the pump has been running for a long time, the gasket has worn out, or due to improper installation. This manifests itself as loss of coolant and leaks around the pump.

If any of the above symptoms occur, the pump must be replaced. The question often arises as to which pump is best to install. There are many pumps for the VAZ 2114 on the market, among which there are many low-quality and counterfeit products. When purchasing, you should visually assess the quality of the build and metal by comparing several options. Make sure the axle is not hanging on the bearings and is at a 90 degree angle. Even a slight distortion indicates a defect - such a pump will eat the timing belt.

There is no answer to the question of which manufacturer is better - there are many positive and negative reviews for each of them. Therefore, it is worth choosing a specific pump, and not its manufacturer.

VAZ pump diagnostics

The engine is overheating. Turn on the heater to check. If the air enters cold, then coolant does not circulate in the system. The pump needs replacing. Most often, failure is associated with a violation of the integrity of the impeller.

The timing belt wears unevenly. The belt becomes loose due to wear on the bushings and bearings. To check the water pump, you will have to dismantle it and examine its current condition.

Coolant leaks . This problem occurs when the water pump operates for a long time. The gasket may be worn out or it was simply installed incorrectly during a previous repair. Regardless of what kind of problem you encountered, the only correct solution is to replace the water pump. It’s quite possible to do this kind of work with your own hands. To do this, you will need a little time, tools and a new high-quality pump that is suitable specifically for your VAZ 2114.

If you're lucky

First, remember: if the cable breaks, do not try to open the hood by force. This will only make it worse, because the metal where it joins the body is not the thickest. Let's first consider an easier case. Regardless of whether it is a VAZ-2114 or a VAZ-2109, you need to open the hood, as you know, from inside the car using the handle. So, if the cable breaks right next to it, then you can untwist it and pick up its tail with pliers. Then pull it towards you and. Both on the VAZ-2115 and on older models the scheme is the same, so do not immediately rule out this option. Actually, after you have opened the hood, you can begin the repair, so that after everything you don’t have to climb for pliers again.

For repair, in fact, you only need one part. Carefully remove the broken cable from the fastenings and install a new one in them. The hood will open normally. The only detail: it is better to ask someone for help to press the spring of the mechanism while you attach the other tail to the handle. Then the cable will be tensioned better.
