VAZ 2113 and VAZ 2114 are quite popular cars in Russia, due to their unpretentiousness and ease of operation. However, this machine has many components that require periodic attention for the purpose of prevention or repair work, and the pump is one of them.
From today's article you will learn: common causes of malfunction of the VAZ 2113 and VAZ 2114 pump, where the pump is located, tips for choosing a pump, signs of a malfunction and step-by-step instructions for replacing this part of the car.
Purpose of the pump VAZ 2113 VAZ 2114
The liquid cannot move through the cooling system on its own, so the design of the liquid system includes a water pump, also known as a pump.
Its main task is to ensure the circulation of coolant through the system, which ensures heat intake and removal.
The pump does nothing else, but the normal functioning of the motor depends on its operation. Without it, the power plant will overheat very quickly, since heat removal will not be provided.
The liquid cooling system of the power plant of any car ensures that the optimum temperature is maintained using liquid. Moving through the channels of the engine cooling jacket, the coolant washes the heated elements, taking away some of the heat from them, and then removes it to the environment through heat exchange processes in the radiator.
Rust, deposits
Symptoms of failure of the VAZ-2110, 2114 or other car models may be different. Upon external inspection of the pump, rust is visible. The most common corrosion is on the impeller blades. This leads to a decrease in the rate of pumping antifreeze into the system. The cause of rust may be contaminated coolant or a compound that is incompatible with the pump. Mixing different antifreezes can also lead to this problem.
Another cause of rust on the pump is damage to the pump cover. In this case, it will not be able to close hermetically. Due to this, air bubbles appear in the composition, which causes oxidation processes.
In this case, the pump will need to be replaced. The cooling system must be thoroughly flushed and new antifreeze added. It is necessary to check the tightness of the cap. You may need to replace it.
The pump should also be replaced if deposits have formed on the inside of the pump. Such signs of a malfunction of a pump 2114, 2110 or another model can only be determined by visual inspection of the system. Deposits of resin, minerals or other substances appear on the internal surfaces of the pump. They clog the pump, preventing the system from working properly.
The cause of this malfunction is contaminated antifreeze or the use of the wrong composition. The system must be thoroughly rinsed with special mixtures. The pump has been replaced and new high-quality antifreeze is added.

Signs of pump failure
You can talk about a pump malfunction if you have the following malfunctions:
- The coolant level in the reservoir drops to a minimum . This reason is the most common, since this is how you can understand that the coolant is constantly leaving due to leaks. They can be in the tank itself, the pipes, or at their connections, as well as directly in the radiator. Only by checking the entire system can you be sure that this is not the reason.
Pump design VAZ 2113 VAZ 2114
On VAZ 2113 and 2114, as on many other domestic passenger cars, the pump has almost the same design. The unit consists of a housing with a central shaft located inside, on which the impeller is fixed. The shaft is secured against axial displacement by means of a bearing, and the tightness of the structure is ensured by an oil seal that prevents coolant leakage.
There is a hole in the pump cover through which the shaft comes out, where the pulley hub and then the pulley itself are attached to it. A belt is put on the latter, which on the “seven” rotates the generator and pump from the crankshaft. On modern cars, the pump rotates via a timing belt.
Preparing the tools
Regardless of what specific problem arose on your car, the only solution to fix it is to replace the pump. This work on a VAZ 2114, VAZ 2115 can be done independently, since the convenient design of the machine makes it possible to carry out all stages of work without special skills.
First you will need to prepare a simple tool:
- wrenches 10, 17 and 19;
- socket head 10;
- flat screwdriver with a thin blade.
Without this tubular socket wrench it will be impossible to unscrew the hard-to-reach bolts on the pump mount
Where is the pump VAZ 2113 VAZ 2114
On VAZ 2113 and VAZ 2114 cars, the pump is located next to the generator and if it fails (When it gets jammed, for example), the generator belt breaks and no current flows to the battery, and also due to the pump getting jammed, liquid flows through the cooling system does not circulate and therefore the car begins to get very hot, but as for front-wheel drive cars, in fact it doesn’t even matter what kind of car it is, VAZ 2110 or VAZ 2114, on all of them the pump is located in the same
place and in motion it is no longer driven by the generator belt, but by the timing belt, and if suddenly the pump jams, then the first thing the belt either breaks or flies off, the entire car is immobilized (the engine in this case will run idling), but with regards to classic cars (We’re just dismantling them as an example), then if the pump is jammed and the generator is immobilized, the car will be able to continue driving, it’s just that soon either the battery will run out or the car will boil.
How to check the serviceability of the pump on a car
Timely diagnostics of the pump allows you to avoid costly repairs or problems with constant overheating of the engine. To answer the question of how to check the pump’s performance yourself, let’s consider diagnostic methods using the example of domestic VAZ cars (model 2109, 2110).
Let's start with the fact that the pump is a kind of “consumable”, which on cars with a pump driven by a timing belt is recommended to be changed every 60 thousand kilometers traveled or 48 months, whichever comes first. These are the regulatory requirements of many automakers.
In simple words, a good pump lasts as long as two timing belts last. It is also worth adding that using spare parts or low-quality antifreeze, mixing different types of coolant, etc. can lead to pump failure ahead of schedule. For this reason, it is advisable to check the pump regularly.
How to check the pump's operation
You should check the water pump on your car using a common method. For diagnostics on a VAZ and a large number of other cars, the engine should be warmed up until it reaches operating temperatures.
- After warming up, you need to hand pinch the upper pipe coming from the radiator. If the pump is working properly, then the coolant pressure created by the pump will be felt. This is the main answer to the question of how to check whether the pump is working or not without removing the pump from the car. During such a check, care must be taken, since the coolant in the system gets very hot. If the fluid pulsation is weak or absent, then you should proceed to a detailed inspection.
- To check, you need to remove the protective casing of the gas distribution mechanism, which will allow for a visual inspection. If the rubber seal (pump seal) in the area of the seat begins to leak, then drips of antifreeze or antifreeze will be visible. Also, leakage and problems with the pump will be indicated by deposits around the seat, which may have a reddish-brown or grayish color. If they are present, you need to drain the antifreeze and remove the pump for troubleshooting and replacement.
- If engine operation is accompanied by a characteristic “howling” sound, then the problem may be in the pump bearing. In this case, the pump is checked for play in the shaft area. To check by hand, you can rock the pump drive gear. In some cases, you can replace the worn bearing or immediately install a new pump.
Which pump is better for VAZ 2113 owner reviews
Before replacing a broken pump with a new one, you should think about which pump is best to install on the VAZ 2114. This is due to the fact that different manufacturers produce pumps of different quality, and not all of them will be able to work properly for a long time.
According to the opinion of the majority of motorists, based on the practical use of pumps from certain manufacturers, it is better to give preference to pumps from the following companies:
- Gates;
- luzar;
- T3A;
They have shown themselves to be the best, ensuring uniform circulation of fluid in the system and having the longest service life.
Where to begin?
There are some signs of failure of the VAZ pump. In these models, the pump ensures the passage of antifreeze through the cooling jacket, hoses and pipes, as well as through the radiator. During the warm season, even a slight malfunction of the pump can lead to overheating.
It is worth noting that the symptoms of a pump malfunction on the VAZ-2112, 2107, 2109, 2114 and some other models should be determined as soon as possible. The fact is that in these models the pump is driven by a timing belt. If the pump jams for any reason, it will fail. This, in turn, leads to deformation of the valves in the engine. This situation occurs in most cases when such a failure occurs. Therefore, it is important to independently identify signs of pump failure in the cooling system.
Knowing the symptoms of failure of the VAZ-2114, 2112 or earlier models, you can avoid expensive engine repairs or constant overheating.
It is worth noting that the cooling system water pump has a certain service life. Once the expiration date has passed, this system component must be replaced. In cars with a pump driven by a timing belt, this element of the system should be replaced every 60 thousand. km mileage This distance is usually around 48 months (with regular driving).
Signs of a faulty pump VAZ 2113 2114
The main symptoms of a malfunction of the VAZ 2113 and 2114 pumps are:
- Noise from the pump when the engine is running. Extraneous sound appears due to bearing wear. It is recommended to replace the cooling system pump after one or every replacement of the timing belt kit. If you neglect service intervals, wear appears on the rolling elements, inner and outer races, which leads to noise and whistling. Often the cause of accelerated wear is antifreeze, which, due to a leak in the oil seal or rubber cuff, gets to the rubbing vapors.

Article Author's Note: Often a decrease in performance is noticed after using a sealant to repair a radiator leak. The poured mixture clogs the cooling system channels and sticks to the pump impeller.
Leaking pump seal VAZ 2113 VAZ 2114
One of the most common signs of a malfunction of the VAZ 2113 and VAZ 2114 pump is its leakage. A pump leak can occur due to wear of the seals or cuff. That is, it will be necessary to remove the pump, disassemble it and replace the worn element. The procedures for removing and installing the pump will be described below.
If the pump has been in use for a long time, it is not advisable to carry out repairs. It is recommended to buy a new water pump and install it in place of the old one.
The appearance of pump noise VAZ 2113 VAZ 2114
If during operation of the VAZ 2113 and VAZ 2114 engine you hear extraneous noise from the pump area, this indicates an imminent breakdown of the unit. The most likely cause of noise is failure of the bearings or weak fastening of the impeller. In any case, the part needs to be dismantled, subsequently damaged, repaired or replaced.
Increased vibration of the pump VAZ 2113 VAZ 2114
Another common malfunction of the VAZ 2113 and VAZ 2114 pump is its increased vibration. This sign indicates wear on the shaft bearing or pump belt tension roller.
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.

How to check the performance of the pump VAZ 2113 VAZ 2114
Checking the correct functioning of the water pump can be done in several ways; we will look at some, in my opinion, the most effective of them using the VAZ 2113 as an example.
- The first method is the simplest; it involves warming up the VAZ 2114 engine to operating temperature (the sensor needle will become vertical). Then you need to clamp the upper radiator pipe; if the water pump is working, you will feel a pulsation of coolant in the squeezed pipe.
- Check the serviceability of the oil seal and whether liquid is leaking through it through the control vent hole of the pump. To do this, remove the timing belt cover, then carefully inspect the above hole. If you find brown deposits, you will need to replace the seal with or without a water pump.
- When a lingering sound is heard from the front of the engine, it can be assumed that the pump shaft bearings have failed. To make sure of this, check the shaft play by shaking the water pump drive sprocket.
- If there are no visual signs of a malfunction, I recommend dismantling the pump and performing a more detailed inspection. Essentially, you need to pay attention to the back of the rotor. The most common problem is blades destroyed by corrosion.
If the water pump on a VAZ 2113 is faulty , repair it or completely replace it.
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.
Removing the pump VAZ 2113 VAZ 2114 - step by step instructions
In order to remove the pump on VAZ 2113 and VAZ 2114 cars, you must follow the following step-by-step instructions:
- First you need to remove the timing belt.
- Now you need to unscrew and remove the camshaft pulley, holding the pulley from turning and unscrew the bolt, the main thing is not to lose the key that is located on the pulley seat.
- Unscrew the camshaft pulley. Then unscrew the 4 bolts that hold the cover.
- Next, move the cover to the side and use a screwdriver to remove the water pump from its seat.
- After this, you need to install the new water pump in reverse order. When installing, make sure that the number written on the water pump is at the top.
Replacement process on a 16-valve VAZ 2114
In 16-valve vehicles, it is more difficult to replace the pump by hand, but it is also possible.
- Remove the plastic cover and seat belt cover.
- To remove the housing that separates the pulley from the engine block, remove the timing belt, camshaft belt, tensioner and belt carrier. Without this you will not be able to remove the pumps.
- You must remove the right wheel to get to the bottom screen screws.
- Remove the pump.
Further essential activities are identical to vehicles with an 8-valve engine.
When replacing the pump, it is important to follow the assembly technique. An incorrectly installed pump will leak just like the old one. In the same way, you can eat the timing belt. There can be many reasons for engine overheating, and if replacing the pump did not help solve this problem, read the corresponding article on the page.
Installing a pump VAZ 2113 VAZ 2114 - step-by-step instructions
The assembly and installation of the VAZ 2113 and VAZ 2114 pumps is carried out in the reverse order. The only thing you should pay attention to is the gaskets - it is recommended to use new ones. In addition, the connections between the pump and the pipes are coated with sealant. When the part is installed, add antifreeze. In order to prevent the formation of air pockets, disconnect the thin hose of the cooling system from the carburetor (on a carburetor engine) and ensure that the antifreeze flows out of the hose and fitting, after which the connection is made.
Start and warm up the engine, inspect the pipes for leaks. If everything is in order, the repair can be considered successfully completed.
Replacing the Fluid Pump
After you have purchased a new pump for the VAZ 2114 (which is better - mentioned above), you should install it. For this you will need:
- Turn off the engine (if the machine is running) and wait until the system cools completely.
- Disconnect the terminals from the battery and remove the drive belts.
- Drain the liquid from the system using a plug bolt (before doing this, remove the cap from the expansion tank).
- Remove the timing belt by first unscrewing the bolts on the protective cover and removing it. (Important! After the belt is removed, it is strictly forbidden to manually turn the crankshaft or camshaft).
- Remove the old pump (sometimes dismantling it may require some effort, since the original pump is additionally fixed with sealant).
- Degrease the surface after sealant (for example, acetone).
- Install the new pump and reassemble in reverse order.
By performing these simple operations, you can quickly install a new pump and return the car's cooling system to normal operation.

Any car parts can deteriorate over time. Despite the fact that the water pump is a durable and reliable device, it can also become unusable. As you know, nothing lasts forever, so over time the pump needs to be changed or repaired. In case of serious damage, it is advisable to replace the pump with a new one, which will serve properly for many years. It is very important to purchase a high-quality and durable part.

How to change pipes on a pump
Replacing the pipe on the water pump is advisable in cases where the hose is swollen or has small cracks through which antifreeze leaks out. A significant disadvantage of changing the pipes is that they are located below the pump - that is, you will have to jack up the body and crawl underneath.
The old pipes are removed after the antifreeze has been drained and the pump itself has been dismantled. It is important to clean the landing site from dust, dirt and coolant leaks. Then connect new pipes to the new pump, installing a new gasket at the junction. It is recommended to use heat-resistant sealant to ensure reliable connections.
Before installing new pipes, it is necessary to drain the antifreeze from the cooling system.
Technical features
First, let's look at the main technical characteristics and features of the water pump; this will allow us not only to make a correct diagnosis, but also to understand why the breakdown occurred.
Antifreeze is pumped using an impeller, which is mounted on a shaft. The drive is carried out from the crankshaft of the motor; a belt drive is used for this. Here it is worth clarifying that in practice there are 2 drive methods used for the pump:
- Directly from the crankshaft
. This method is used on engines with a timing chain. Usually one belt drives the generator and pump, sometimes the power steering and air conditioning pump are also connected here; - Another option is timing belt drive.
There is one serious drawback here. When the bearing jams in the pump, the belt breaks, which leads to breakdown of the gas distribution system, and under certain conditions, to a complete overhaul of the engine. In this case, you should carefully monitor the condition of the pump.
The pump housing is usually located at the front of the motor. This allows for the most optimal pumping of coolant through the system. It is also precisely this approach that makes it possible to use the crankshaft pulley as a moving element. In addition, placing the part at the front makes it easier to access for repairs.
The main malfunctions of the pump are directly related to its technical features; accordingly, this must be taken into account when carrying out diagnostic actions. As a rule, all signs of a malfunction are completely related to the characteristics of the various elements that ensure the operation of your car's cooling system.
conclusions
If traces of scale are visible on the pump, the cooling system must be flushed urgently
All the causes and symptoms of a malfunction in the VAZ-2114 water pump have been examined, 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.
