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.
Is it possible to drive if the pump is jammed?
Many car owners are concerned about the question: is it even possible to operate the car if the pump does not work? And if so, what is the best way to drive?
The whole thing comes down to two components:
How necessary is it to use the car?
Of course, if the pump is jammed, the circulation of antifreeze in the system will be disrupted. Accordingly, the engine can only be cooled naturally. Therefore, it is better not to start the car, since overheating of the engine brings certain death to your four-wheeled friend. However, it is allowed to drive a faulty car if it is cold outside. The engine is less susceptible to overheating, but you should avoid traffic lights and forced stops, as the engine heats up faster due to changes in the number of revolutions.
That is, most problems with the pump can be solved on your own. With the affordable cost of this pump, you can change the pump immediately when necessary. However, experienced drivers do not make a replacement until the product begins to act up. Practice shows that the pump's service life is much higher than stated by the manufacturer. Therefore, you don’t have to worry about repairs and replacements if the cooling system is operating normally.
There are many elements in the cooling system of the VAZ 2114, one of which is the water pump. Among motorists, the unit is better known as a pump. The pump rarely fails. But if this happens, then operating a car with a faulty pump can lead to overheating of the power plant. To keep all elements of the engine and cooling system in working order, you need to carry out regular inspection. This also applies to the water pump.
Cooling of the vehicle's power plant occurs due to the circulation of coolant. The pump, which is driven by the timing belt, is responsible for the circulation. If the pump breaks down, the coolant circulation stops.
Once you understand the purpose of the pump, you can easily check its functionality. There are a lot of ways to check, but most motorists prefer to do this using the upper radiator hose. It must be clamped while the engine is running. If a pulsation of coolant is felt inside the hose, then the pump is working properly and replacement is not required.

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.
How to fix the problem?
If a malfunction is identified, it should be eliminated as soon as possible. Here it is worth understanding that the pump is still a consumable, and in most cases it is easier to completely replace it.
If there is a leak through the gasket, simply remove the pump and replace the gasket. Please note that normal tightness is required here. Therefore, be sure to carefully tighten the fastening nuts. Many drivers lubricate the gasket with sealant; such a precaution will not be superfluous. This will significantly reduce the risk of leakage. After some time, you should check the tightness of the nuts; they may loosen due to engine vibration.
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.
How to diagnose
Before you begin troubleshooting, you must remove the plastic cover that covers the gas distribution mechanism. But you can recognize some signs that indicate problems with the pump:
- Extraneous sounds when the engine is running. Usually they indicate that the pump bearing has become unusable. But you need to make sure that the source of the sound is the pump. Since if there is excessive wear, the tension roller can also signal a breakdown in a similar way.
- During long-term parking, traces of coolant appear on the timing belt side.
- In the case when the engine temperature rises sharply while driving, we can say that there is a shortage of fluid inside the system. This can occur due to a malfunction of the radiator, pipes, or liquid pump.
- One of the most popular faults is drive pulley misalignment. In this case, the timing belt begins to run against the outer edge of the tension roller. A small groove will appear on the outside of the belt. In this case, it is necessary to replace the VAZ-2115 8 valve pump (injector) as quickly as possible.
To make an accurate diagnosis, you need to use a “10” wrench to unscrew the bolts that secure the protective cover of the timing mechanism. After this, you need to use a key set to “17” to loosen the belt tension. To do this, unscrew the nut on the roller.
Grasp the fluid pump drive pulley with your hand. If there is play, the pump must be replaced. But if there is no play, but there are traces of antifreeze under the casing of the gas distribution mechanism, be sure to replace the VAZ-2115 pump (8 valves). Try to diagnose the fluid pump every time you replace the timing belt.
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.
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.
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.
Replacing a pump in a 16-valve system
What are the possible causes of pump failure? This question worries not only beginners, but also quite experienced car enthusiasts. Here are the main reasons, from the most common and widespread to the “exotic”. Among them:
Faulty bearing. This device wears out due to natural reasons. However, accelerated wear is possible due to additional negative factors. For example, incorrect (higher) belt tension results in increased load on the bearing. Another reason for significant wear is the transfer of antifreeze to friction pairs due to leaky seals and coolant leakage.
Damage to the seal. The pump has two seals - a packing and a rubber gasket. Most often the sealant (gasket) is damaged. This happens for two reasons - natural wear and tear (tanning of rubber) and the use of cheap, low-quality antifreeze without appropriate additives or even water. After a longer period of time, these liquids “eat up” the seal, it begins to leak, which leads, firstly, to a decrease in the level of coolant in the system, and secondly, to the entry of antifreeze or water into the bearing, washing out the lubricant and the problems described higher.
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.
In what cases is repair possible?
Repair is a procedure that is not always advisable. This is explained by the fact that the product itself for most models is not expensive at all. That is, it is easier to buy a new pump than to waste time and effort on repairing the old one.
Repair is not recommended on those models where it is driven by a hydraulic timing belt. The fact is that after repair the part may not be as reliable as a new product, which will affect the production of the belt.
Any repair work that is in principle possible is based on replacing the oil seal, bearing or impeller. These consumables are freely available and cost pennies. However, it is still more advisable to completely replace the pump than to repair it. This is due to the fact that access to this unit on some cars involves using an inspection hole and unscrewing the engine mounts. That is, for the sake of minor repairs it is necessary to carry out rather complex preparatory work. Therefore, it is easier for car owners to immediately install a new pump.
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.
Why does the pump break down?
Before dealing with the signs of a malfunction of the pump 2110, 2107 or other models, you should pay attention to the reasons for the rapid wear of this system component. A high-quality pump can withstand about 100-110 thousand. km mileage For this reason, not all drivers change them after driving 60 km, as indicated by the manufacturer.
Most often, replacing the pump coincides with the second replacement of the drive belt, which is mounted in the timing belt. Therefore, replacing the pump usually neatly coincides with replacing the antifreeze.
High-quality pumps have a long service life. They can serve as long as you like, like two timing belts. However, it is not always possible to buy a high-quality pump. Such a device is not capable of operating without failures for a long time. Therefore, problems arising in the cooling system cannot be ruled out.
Low quality antifreeze or mixing different types of coolant can shorten the life of the pump. This causes the pump to fail much earlier. For this reason, the driver is recommended to regularly check the pump for faults.
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.
DIY pump replacement
Removing the VAZ 2114 pump
The replacement process depends on how many valves 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.
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.
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.
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.
Possible problems after replacement
Unfortunately, behind the apparent ease of removing and installing the pump, several problems can be hidden. For example, the pump is very sensitive to tightening - as soon as you twist the bolts a little, the gasket is squeezed out. Many such nuances may arise after replacement.
There was a noise
Noise and whistling sounds from the pump while driving are the most common problem after replacement. There may be several reasons for new sounds:
the bolts are tightened too tightly;
If noise does not affect the performance of the cooling system in any way, that is, fluid circulation is carried out normally, then the part does not need to be changed.
The stove began to heat poorly
If, after replacement, the stove in the cabin began to produce slightly warm air or stopped heating altogether, then there is an air lock in the cooling system. It is necessary to warm up the car to operating temperature and sharply accelerate it - as a rule, these measures are enough for the traffic jam to be overcome and the heater to work as usual.
Also, problems with “heating” can arise due to the fact that the impeller blades on the new part have a slightly different gap. It is impossible to solve this problem, so it is recommended that you initially select a pump from the same manufacturer as the old product, with identical markings.
It is recommended to give it a good throttle to break through the air lock.
Good night! a couple of days ago I changed the pump on the Hunter 409 engine, and the heater at idle began to blow slightly warm air, when you put it on the gas and keep it at rpm it starts blowing hot, the temperature floats from 80 to about 100 when the idle is about 100 at rpm it drops to 80. When the old pump was standing, it was hot in the cabin in the cold, but it rattled, the impeller on the old one was like a textolite round one in the middle with slots like a spiral, and on the new one the impeller was like blades. Due to the difference in the impellers, can the fluid be driven worse? and it seems like they write that since 2007, only impellers have been installed on pumps, or what about blades?
