How to change the pump on a VAZ 2113, 2114, 2115

The water pump of the engine cooling system, or simply the pump, is the most important element that is responsible for pumping coolant through the channels of the cooling system. Fluid circulation in the system is mandatory to maintain normal engine operating temperature.

If the pump wears out, partially or completely fails, you may encounter the following malfunctions:

engine overheating;
coolant leaks through the pump;
extraneous noise in the pump area;
water pump jamming and timing belt breakage;

To avoid serious damage, regular inspection and timely replacement of the VAZ 2114 pump is necessary. To do this, you will need to remove the drive from the water pump, dismantle the pump and correctly install the new pump. Read more in our article.

Why do you need a pump in a car?

The pump promotes the movement of fluid (antifreeze or antifreeze) in the cooling system. There is a shaft inside the mechanism. An impeller is attached there, and when it rotates, circulation occurs.

On the opposite side, a pulley is attached to the shaft. The system is activated by the rotation of the part in the gas distribution mechanism (GRM). When the pump becomes unusable (most often jams), the car engine may overheat. In case of some breakdowns, antifreeze begins to leak from the device.

In cars, a centrifugal type water pump is most often used. This option is characterized by its simplicity of design and durability.

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.

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.

How to determine pump wear

Experienced motorists will easily notice wear and tear on the water pump. It is difficult for beginners to identify a faulty part. Signs of wear are described below.

Engine overheating

When the engine temperature on the dashboard is above 90 degrees, the pump is faulty, especially if overheating occurs in winter.

This symptom, accompanied by a light on the dashboard, indicates a faulty part. Antifreeze boils and steam comes out of the radiator. The car cannot be driven.

To verify the source of the malfunction, you must:

Warm up the engine to 90 degrees.
Set the stove control panel to hot air and turn it on.

If the pump is working properly, heat should flow. If cold air comes out at the operating temperature of the engine, this is a sign of a broken impeller. The pump needs to be replaced.

Uneven timing belt wear

The mechanism is started by the timing belt. If there is a problem, the neoprene product may wear unevenly. You can verify this by removing the belt and inspecting the product. On one side there will be more wear.

The problem is related to the exhaustion of the life of the pump bearings. The part itself may still work properly.

Uneven wear may be due to a bent fastener. You can check for misalignment by holding a ruler or other flat object to the belt.

Leakage

The most common pump problem faced by VAZ 2114 owners is a leak. It can come from under the oil seal, impeller or housing. Liquid will be observed on the device body, mounts or engine protection.

If you notice drops that accumulate for a long time, the problem is not critical and does not need to be fixed urgently. If there is a lot of fluid, intervention is necessary.

Sometimes antifreeze leaks after replacing the pump. This means the gasket is installed incorrectly.

Another indicator of a pump malfunction is the smell of antifreeze in the cabin. It may also indicate other faults.

Attention! The listed signs indicate not only a pump malfunction, but also a malfunction of the cooling system, which is recommended to be checked.

The water pump is a non-repairable part of a car. If it breaks, only replacement will help.

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;

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

Dismantling

Before starting work, you need to understand where the part is located. The water pump is located on the left side of the engine compartment, under the camshaft pulley, so when it jams, the timing belt flies off.

The removal process is simple; the engine must cool down before doing this.

In a vehicle with an 8-valve engine, the following actions are required:

Disconnect the terminal from the battery.

Disconnecting the terminal from the battery

Remove the timing case (held on by 3 bolts).

Removing the timing case

Place a mark on the camshaft so that it aligns with the mark on the engine. You need to jack up the car and slowly turn the right front wheel, having previously installed 4th gear.
Move the timing belt. The product needs to be loosened; the tension roller will need to be removed.
Unscrew the ignition module mounting bolts without disconnecting the contacts. This is necessary to get to the antifreeze or antifreeze drain plug.
Prepare a container where the liquid will flow and a hose.
Unscrew the plug with a key set to “13”. Place the hose, which should be directed into the container.
When the pressure becomes weak, the lid can be screwed back on. There is no point in draining all the liquid; to make the process easier, you can leave a little.
Then remove the container.
Remove the thin pipe. The part is connected to the throttle valve heating unit.
Remove all heating pipes.
Wedge the camshaft gear teeth with a screwdriver and unscrew the fastening bolt.
Remove the pulley.

Pulley removal

Remove the metal casing (secured with 5 bolts).
Unscrew the pump. Using a wooden block, tap the device body and dismantle it.
Clean the sealant from the seating area.

Attention! During the replacement process, it is recommended to check the timing belt and pulley. If the condition of the parts is poor, they must be replaced along with the pump.

Before installing a new pump, you need to check the old one for play. Check the tightness of the oil seal. If there is no play or leaks, the old pump can be reinstalled.

It is necessary to change the rubber gasket even if it shows no signs of wear or damage. To ensure reliable sealing, it is recommended to coat both the pump mounting location and its junction with the cylinder block with a heat-resistant sealant.

It is recommended to ensure that the new and old pumps are completely identical.

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.

How to install an additional pump on a VAZ 2114, 2115

Experienced VAZ owners know that the “fourteenth” and “fifteenth” are ideal for conducting a variety of experiments on installing this or that equipment. For example, if the standard heating on a VAZ 2114 through the stove is not enough for the owner, then you can install a second (additional pump). The essence of this procedure is that the pump will pump antifreeze in a small circle, thus providing better engine cooling and maintaining the temperature in the cabin in winter.

A second water pump keeps the cooling system running at peak efficiency.

Installing an additional pump takes a maximum of 10 minutes, but the procedure will increase slightly in time due to the fact that you will have to drain the antifreeze from the system.

You will need to purchase the following spare parts in advance:

water pump (for models 2114 and 2115, the ideal solution is a pump manufactured by Bosch 0 392 020 034);
elements of electrical equipment;
several hoses of different lengths (depending on the diameter of the small circle) with clamps;
fastening for the pump.

Assembling the structure

In this case, you will already need some experience in independently servicing a VAZ. So, to install an additional pump, you need to:

Assemble this unit itself from three parts - a pump and two pipes (the shortest hose works for the outlet, the longer one for the suction of antifreeze).
Next, drain the coolant from the system.
Near the bottom of the car, feel for two hoses coming from the stove, remove the one that works for the outlet.
Instead, connect the assembled unit.
After this, attach the pump itself to the crankcase of the manual gearbox. It is better to use brackets and screws for this.

The final stage is pouring new antifreeze.

To mount the pump, you can use any type of fastener, the main thing is to ensure the reliability of the connection

Replacing the pump on a VAZ 2114, VAZ 2115 (16 valves)

The procedure for replacing the water pump on 8 and 16 valve engines will be slightly different. The fact is that on a VAZ 2114 with 8 valves there is only one crankshaft pulley, and on cars with a 16-valve engine there are two. That is, the designs of cars with different types of engines are somewhat different from each other.

In this regard, you need to be extremely careful: pumps for VAZ with 8 or 16 valves cannot be considered interchangeable. That is, when purchasing a new water pump, you should make sure that it is suitable specifically for your type of VAZ engine.

Water pump replacement procedure

First you will need to remove the plastic timing belt protection cover, but this is not as easy as on a VAZ with 8 valves:

In order to remove the casing, you will need to remove the pulleys from both crankshafts.
And you also need to disconnect two timing rollers - support and tension.
It is impossible to remove the pump without dismantling the pulleys and rollers.
You will also need to remove the right front wheel. It is recommended to use a jack to raise the body to the desired height. This is the only way to get to the bolted connections that secure the timing case to the engine.
Next, you can be guided by the diagram that is given for 8-valve engines.

The work of replacing the water pump on a VAZ 2114 and VAZ 2115 is not particularly difficult. The main thing is to carefully approach each stage of the procedure and work only with serviceable tools. Replacing a pump yourself is a job that does not require special training.

Replacing the pump on VAZ 2113, 2114, 2115

When replacing a new part, a high-temperature sealant must be applied to the flange and the gasket that must be installed in the socket.

A new pump for a VAZ 2115 car is mounted as follows:

Screw the bolts and tighten them onto the pump flange.
Install a metal casing. Tighten the fastening bolts.
Install the camshaft pulley. Tighten the bolt.

Installing the camshaft pulley

Install the tension roller and timing belt.

Installing the tension roller and timing belt.

Use pliers to adjust the tension level of the product, which should not turn sideways by more than 90 degrees.
Install the protective cover of the timing mechanism made of plastic.
Fill with coolant until it begins to flow out of the removed throttle body pipe.
Install the pipe, tighten the fastener.
Fill with antifreeze or antifreeze to the required volume.

After replacing it yourself, you need to start the engine and warm it up. Then it will be clear whether the pump is working properly or not.

Since 2011, some modifications of the VAZ-2113 and 2114 have had 16-valve engines installed. The pump changes on them in the same way, but there are some differences:

It is necessary to remove two camshaft gears.
The support roller needs to be removed.
To get the protective cover, you need to remove the wheel.

The 16-valve modification of the “fourteenth” model is demanding in terms of correct marking.

Attention! Water pumps for engines injector 8 and 16 valves are different.

Troubleshooting

Since the water pump on the VAZ 2114/15 is completely covered by a plastic casing of the gas distribution mechanism, it is impossible to visually determine malfunctions. The main signs of problems with the water pump are as follows.

While the engine is running, extraneous sounds (humming or grinding) can be heard from the timing belt, which can be produced by a faulty pump bearing. However, a similar hum may appear if the timing belt is tightened after replacement, as well as if the tension roller is heavily worn.
Traces of antifreeze were found on the timing case, under the car after parking, or on the underbody.
A sharp increase in engine temperature while driving is a consequence of the loss of most of the coolant. This can happen due to a breakdown of the radiator or the final failure of the pump.
As a result of bearing jamming, the gear and pump shaft become distorted, which can cause the timing belt to break.
If the engine stalls while driving and the temperature sensor needle rises to the maximum, most likely the water pump shaft is jammed and problems appear in the gas distribution mechanism.
If the water pump seal leaks antifreeze, traces of it are visible on the cylinder block

To make a more accurate diagnosis, you should do the following.

Using a 10mm wrench, unscrew the three fastening bolts and remove the protective plastic casing.
The three mounting bolts are unscrewed and the protective casing is removed.
Using a nut, loosen the belt tension roller.
Use your hands to check for play on the water pump shaft. If the gear is loose, the pump must be replaced.
The presence of traces of antifreeze under the casing is most often a consequence of oil seal wear.
Difficult shaft rotation indicates bearing wear.

Almost always, diagnosing the water pump is done when replacing the timing belt. According to the technical documentation for VAZ 2114/15 cars on 8V engines, the belt should be changed every 60 thousand km, on 16V engines - every 45 thousand km.

Replacing pipes

When replacing the pump, pay attention to the condition of the pipes. If there are cracks or damage resulting in coolant leakage, the product must be replaced. It is recommended to do this when the pump is removed; there is no need to drain the antifreeze a second time.

The main disadvantage of the replacement is that the hoses are located low; to get there, you need to lift the car.

Replacement process:

Drain the coolant.
Remove the water pump.
Clean the seats.
When installing at a joint, install a new gasket using high-temperature sealant.

Which pump to choose?

Before you change the pump on a VAZ 2114 with your own hands, you need to start looking for a new spare part. It's better to opt for the original. Most car enthusiasts advise installing it, since the concept of price and quality of the product is superior to its competitors.

The part can be found by article number: 21114-1307010-82 . When purchasing, look carefully to see if it is printed on the box, since there are Chinese analogues on the market made to resemble the original. The cost of a high-quality element is about 1,200 rubles, and analogues of poor quality are much cheaper.

Another brand that can be recommended for purchase is Marel . The company produces spare parts not only for domestic cars, but also for foreign cars. At the same time, it has positive reviews from many car owners. The price of the part is about 1300 rubles . You can also focus on one of the most reliable but expensive brands - Valeo . The mechanism runs 50% more than domestic ones, but has prices of about 3,000 rubles . Another disadvantage will be the large number of Chinese fakes.

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.

Results of the work carried out

After the work is completed and the time allotted for the sealant to harden, we start the car (VAZ-2115) and conduct a test drive a short distance, preferably on an uneven section of the road. If you don’t smell antifreeze in the car’s interior, and there are no extraneous noises or knocking coming from the engine, then the work to replace the cooling system pump has been carried out efficiently.

Thus, you have gained experience in replacing the water pump of your own car 2115 and saved about one thousand rubles, which would have been required when replacing it at a service station.
