How to recognize and fix water pump problems on a Lada Priora: instructions and tips

A car water pump (or in other words, a pump) plays an important role in the normal operation of a car engine. Thanks to this device, coolant circulates through the channels of the cooling system without delay and reduces the temperature of all heated components of the power unit. A malfunction of the water pump can lead to unwanted overheating of engine parts and even completely render it inoperable. To avoid such an outcome, you must carefully monitor the condition of the pump.

What is the best pump for Priora?

The pump is the most important element of any car, including Prioras.
It ensures coolant circulation, thereby avoiding overheating of the machine. However, a number of problems can arise with the part. However, it cannot be repaired; if it fails, it will have to be replaced. However, every car enthusiast wants to install products from a good manufacturer on their car. Today we’ll talk about why a pump can break, how to choose one for a Priora and which one is better.

The pump consists of several elements that ensure its operation.

In particular: You can determine the malfunction of a part by ear.

Pay attention to noise from the timing belt.

If you hear a rumble, then the reason may lie in this element. Let's look at the main list of breakdowns:

Life hack: Priora car pump 16 valves

No driver expects his car to suddenly “boil.” This is one of the worst scenarios of the day - you will have to stop and cool the car. Rule out problems in advance - first of all, inspect the Priora pump. If the water pump of a Lada Priora car with a 16-valve engine fails, this will instantly extinguish all the car’s efforts to cool it. In addition, the timing assembly, rollers and pump break down - and this is a disaster for the engine because all these spare parts are dependent on each other. The supplied device works like a pump - it pumps up antifreeze and forces it to flow through the circuit at a certain speed, it manages to “release” the heat it receives from the engine. A pump replacement is needed when the Lada Priora pump breaks down, the coolant “stands up”, accumulating all the heat inside itself and releasing it to the surrounding air with less efficiency. That is why this device should not be allowed to malfunction.

Checking the serviceability of the water pump without dismantling it

To determine whether the water pump is working properly on a Lada-Priora without removing it from the car’s engine, it is necessary to take the following steps:

• start and warm up the power unit to its operating temperature;
• squeeze the upper hose from the radiator with your hand;
• By tactile sensations you can understand that coolant circulates through the cooling system, which means the water pump is working properly.

The presence of extraneous hum or noise in the pump area indicates an imminent possible failure of the device bearing. In this case, it is recommended to replace the auto pump with a new one.

During normal operation of the pump, coolant circulates intensively through this pipe.

Job

You should start replacing the pump with preparatory work. To do this, drive the car into the inspection hole. This option is more convenient compared to the overpass. Drain the antifreeze. Remove the terminals from the battery, this is done to prevent an accidental short circuit. You also need to remove the belt from the generator. Some drivers remove the wheel and fender liner, but this is not necessary:

• The first cylinder is installed at top dead center. To do this, remove the right mudguard. At the same time, the front cover is dismantled. After which the crankshaft is turned (strictly clockwise) so that the marks on the pulleys and the engine coincide. Then remove the plug from the clutch housing. The mark on the flywheel must completely coincide with the one located on the motor;
• The crankshaft pulley is removed; to do this, an assistant must keep it from turning by inserting a mounting blade into the hole in the clutch housing. To unscrew the pulley you will need a 17 key;
• After which the camshaft is removed, to do this you need to hold the pulley with a special device. You can do without devices. Shift into fifth gear and press the brake pedal. Thus, you can remove the camshaft pulley without any problems;
• Remove the bracket;

• The back cover is removed;
• Next, use a hexagon to unscrew the pump. Then it is removed using a slotted screwdriver;
• Be sure to ensure that the old gasket is removed. Sometimes the gasket may burn. Cut off the remains and clean the pump landing area;
• Next, the installation site needs to be lubricated with sealant and a gasket is installed. Afterwards it is lubricated with sealant again. Install the pump. It must be placed with the number facing up;
• Reassembly is in progress.

During the assembly process you need to pay attention to some nuances. First, you need to pay attention to the installation of the pulley according to the marks. This is an extremely important point. You should also carefully tighten the timing belt. To do this, use a special key to turn the roller until it is offset with a mark - a rectangular protrusion. Next, the bolt is tightened with a torque wrench with a certain force. Article on the topic “How to set timing marks.”

How to change the pump on a 16 cl engine with your own hands

Before you begin removing the pump, you will need to drain the coolant. We find the drain plug, substitute a container with a volume of about 4 liters and drain.

After draining the liquid, remove the upper decorative cover, the alternator belt, and then the front timing cover, it consists of two parts.

Now you need to set the timing marks so that during assembly you do not make a mistake with the ignition value.

Next, unscrew the pulleys. To prevent the pulley from turning, engage 5th gear and press the brake. Now the pulley will be motionless, you can safely unscrew it. Unscrew the pulley bolts using a 17mm spanner.

If you have a car with air conditioning, you need to use a 13 mm socket wrench to unscrew the bracket for the generator belt tensioner pulley and air conditioner with steering wheel.

The next step is to remove the crankshaft pulley. To do this, remove the right front wheel and mudguards. Next, engage 5th gear again and press the brake. The pulley will be fixed and can be safely unscrewed. Remove the pulley and timing belt.

Next, unscrew the 6 bolts securing the cover and then carefully remove it from the engine.

We unscrew the 6 bolts securing the pump, carefully pry it up with a screwdriver and pull it out. When installing a new pump, it is necessary to coat the gasket with a thin layer of sealant and screw it into place. Next, we reassemble in the reverse order, taking into account the timing marks.

Review of water pumps for Lada

/

08/11/2015 There are currently a variety of brands and manufacturers of water pumps on the market; each manufacturer claims that its products are the best.

In addition, when the pump fails, the cooling of the car sometimes worsens, which automatically leads to increased overheating.

We will try to impartially figure out what’s what, and consider one of the most popular items - a pump for front-wheel drive eight-valve VAZ cars. To avoid any confusion, let's clear things up right away. Eight-valve engines on front-wheel drive VAZs were constantly modernized and changed, so the pumps listed below are suitable for all engines equipped with the so-called “eighth” timing belt.

If we take it by model, then these are VAZ 2108, 2109, 21099, 2110, 21013, 21014, 21015, as well as Kalinas and Prioras of the first years of production. We purchased seven samples of pumps from different manufacturers - both domestic and foreign.

But before we start introducing the products, I would like to explain some of the terms that are used below. The impeller is a low impeller, which is located on the reverse side of the main impeller, its purpose is to relieve the shaft-housing seal.

Equally important is the presence of holes in the base of the impeller - they also help reduce the load on the mechanical shaft seal with the housing.

A ball roller bearing is a bearing that has balls on one side and rollers on the other. Such a bearing can carry greater loads than a double-row ball bearing.

Self-replacement of the pump on a VAZ 2110 (8 valves)

1. Place the car on a viewing hole or overpass.
2. Open the hood, turn off the power by removing the wire from the negative terminal of the battery.
3. Open the expansion tank cap.
4. Go down into the pit, place a wide-necked container (at least 5 liters) under the cylinder block.
5. Unscrew the coolant drain plug (key 13) and drain it. Screw the drain plug back.
6. Unscrew the 3 bolts securing the timing case (10mm wrench).
7. Remove the cover.
8. Set the crankshaft to the top dead center position of the first cylinder. To do this, turn off the gear and turn the bolt securing the generator pulley with a 19mm wrench until the mark on the camshaft gear matches the mark on the rear timing case.

9. Check the alignment of the marks on the flywheel and clutch housing. To do this, remove the rubber plug on the crankcase to the right of the cylinder block.
10. Secure the crankshaft in this position by inserting a large slotted screwdriver into the flywheel teeth.

11. Loosen the nut securing the tension roller (17 wrench) and turn it counterclockwise with a special wrench, loosening the tension of the timing belt.

12. Remove the belt and tension roller.
13. Unscrew the 5 bolts securing the lower timing case, incl. and 3 bolts securing the pump (head or end cap 10). Remove the cover.

14. Using a screwdriver, pry the pump housing and pull it out. Clean the surface of the seat from fragments of the old gasket.
15. Lubricate the gasket on both sides with automotive sealant and place it on the new pump housing.
16. Install the new pump into place.
17. Carry out assembly work in reverse order. It will be better if you replace both the belt and the tension roller along with the pump. This way you will know exactly the resource of all these parts.
18. When installing the timing belt, check its tension by turning one of its fields horizontally. The correct tension is one at which the belt can be rotated by finger force no more than 90 degrees.

Replacing the Lada Priora pump with your own hands - step-by-step instructions

1. We drive into a pit or take it up on a lift. We put it on the handbrake and in 1st gear (if you have a hole).

1. We find the drain plug, place a container under it and drain the coolant.

1. Once the fluid has been drained, you can begin to remove the decorative cover and alternator belt. Then you need to remove the front timing cover.

1. We put marks, for which, I think, it is clear, in the future you will combine the marks with each other so as not to displace or break anything.

1. We dismantle the camshaft pulleys, this is done as follows - engage 1st gear, if you have not done this before, ask a friend to press the brake pedal or put some kind of emphasis on the brake pedal. We unscrew the pulleys themselves with a key set to “17”.

1. If your Priora is equipped with power steering and a Conder, you will have to unscrew the tension roller mounting bracket, which can be seen in the photo; it is secured with three 13-key bolts.

1. Next, we remove the crankshaft pulley, it is necessary to remove it, otherwise you simply will not be able to remove the timing belt, therefore, you will not be able to remove the rear timing cover.

1. Removing the pulley took a lot of effort. It was like this: turn the steering wheel to the right, remove the boot, the assistant should engage the gear and press the brake, meanwhile, using an extension cord and a little effort, unscrew the bolt securing the pulley to the crankshaft.

1. When the timing belt is removed, you need to unscrew the 6 mounting bolts of the cover, then carefully remove it.

1. It remains to unscrew the three bolts securing the pump, after which it can be removed for subsequent replacement.

1. Before replacing the pump on a Priora , it is necessary to clean the seat and also apply a thin layer of sealant for a more airtight connection.

1. The new water pump is in place, you can safely begin assembly, it is done in the reverse order. Finally, don’t forget to tighten the timing belt. Read about how to tighten the timing belt in this article.

I have everything, I hope everything is clear to you, let’s assemble the tool and check the work. Good luck to everyone and see you again at VAZ Repair.

Selection and replacement of pump (water pump) Lada Priora

A water pump, or, as it is popularly called, a water pump, is installed on all cars with a gasoline engine without exception and is designed to cool the engine. The pump is located on the right side of the engine in the direction of travel of the car.

Getting to it for replacement will be quite problematic, both on 8 and 16 valve engines.

How to determine the need to replace your pump

A water pump can fail for two main reasons - wear of the bearing or oil seal. When the bearing wears out, a distinct hum will be heard, which is a sign that such a pump needs to be replaced. If a pump with a faulty bearing is not replaced in time, this can lead to it jamming.

The second reason for pump malfunction is leakage from under the seal. If you notice that your antifreeze or antifreeze has begun to run out, one of the reasons is precisely the pump. Check for fluid leaks in the area where the pump is located.

If so, the pump is most likely leaking. In this case, operating the car is not advisable, but is possible provided that you have to constantly add coolant.

Another sign of a pump malfunction is a worn timing belt. If the bearing is broken, the pump may “walk” slightly, which will cause the belt to eat up, and as a result, the timing belt may break and then you will have to deal with the capital of the motor, since the valves will bend.

The original pump TZA 21126-1307010-75 is installed from the factory. The cost of the pump at the moment is from 800 rubles and more, depending on the region. If for some reason you cannot find a TZA pump, you can choose a water pump from other manufacturers.

• SOATE (St. Oskol) 021126-1307010
• LUZAR LWP 01274 TURBO-2

All of the above pumps are designed for a 16 valve engine. When choosing a pump, we recommend purchasing a high-quality analogue or an original, so that you don’t have to change it again after 20-30 thousand kilometers.

The original pump TZA 2109-1307010-75 is installed on the 8-valve engine. Its cost ranges from 900 rubles and above. Several types of analogues are also offered at lower prices.

• LUZAR LWP 0108

Choose a pump not only based on reviews from friends, but also based on the quality and cost of the water pump. Beware of counterfeits, as there are quite a lot of such spare parts now.

Recommendations for selecting and replacing a pump

When choosing a pump, be sure to purchase one that is suitable for your motor. A pump for a 16 valve engine is not suitable for an 8 valve engine. The difference in replacing the water pump is that there is 1 pulley on an 8-valve engine, and 2 on a 16-valve engine. By the way, from this article you can learn how to replace the fuel pump on a Lada Priora.

How to change the pump on a 16 cl engine with your own hands

Before you begin removing the pump, you will need to drain the coolant. We find the drain plug, substitute a container with a volume of about 4 liters and drain.

Replacing a pump on an 8 valve engine

Unlike the 16 valve, 8 valve. motor replacement is much easier. However, you will still have to remove the timing belt and drain the coolant.

Possibility of installing an additional water pump on the Lada Priora

One of the disadvantages of the heater on the Lada Priora car is its low efficiency when the engine operates at low speeds in the cold season, due to insufficient coolant circulation. Therefore, the car interior warms up slowly and insufficiently, which causes some discomfort for the driver and passengers.

There are some requirements that must be met to obtain a high-quality result after installing an additional electric pump.

These include the following points:

• the installed product should not create excess pressure in the heater radiator during operation in order to avoid damage to the pipes or the formation of cracks;
• It makes sense to replace the thermostat and install this component with an increased opening temperature (90–95 degrees Celsius) due to the fact that as the speed in the coolant circulation increases, the engine parts will warm up more slowly, increasing wear on the power unit.

To solve this problem, you can install an additional water pump in the cooling system of the power unit, which will qualitatively improve the heating of the car interior even when the engine is idling. This technology is not new. Engineers have been using it for a long time. Examples include German cars BMW or Mercedes Benz.

Device selection

As a rule, devices from various manufacturers are suitable as an additional water pump for the Lada-Priora car.

These, for example, could be brands from:

• Bosch company;
• ;
• .

Video: positive effect of installing an additional electric pump on the Lada Priora

However, most often the Lada Priora is equipped with an electric water pump, which is installed on Gazelle cars. This may be an old or new design, but the principle of operation is the same for both: due to the vacuum at the inlet during operation of the product, a pumping force arises, which drives the coolant through the system. In fact, the pump from the Gazelle car is a classic centrifugal pump.

The design of the new pump version is much more successful and causes fewer complaints from car enthusiasts. And it is also less noisy during operation. The main problem that motorists encounter when using such an electric pump is its leakage.

Installation and connection of an additional electric pump

To equip a car with an additional electric water pump, you will also need a regular relay that has normally open contacts (this can be an ignition or starter relay from a VAZ 2105, VAZ 2108). It is necessary to close contacts No. o86 and No. o30. And you will also need a reinforced hose and clamps for clamping the pipes.

An additional pump can be installed in any of the gaps in the supply or outlet pipes of the car’s heating stove.

Installation of an additional electric pump is quite simple, and the efficiency of the heater increases significantly

The pump is fixed in the Lada Priora in the following places:

• stud for fastening the washer reservoir;
• studs located next to the battery;
• on the engine shield.

The device can be connected to a wide variety of systems.

It could be:

• recirculation button;
• SAUO stove block;
• heated mirrors;
• other convenient places.

Content

Water pumps (very often called pumps) are devices that are designed to pump various types of liquids.

In our case, such pumps pump coolant in car engines. They also ensure the removal of excess accumulated heat from the cylinder block and the supply of hot liquid to the interior heater radiator. What are the advantages of LUZAR water pumps? 1) Double row ball roller bearing.

LUZAR pumps are equipped with the best and most suitable bearing from all possible and available options.

The installed bearing has a smaller contact surface area and can therefore operate at high speeds. This guarantees maximum and long-term use. It happens that on some pumps, due to the small height of the housing, ball roller bearings cannot be used, therefore, in such cases, special double-row angular contact ball bearings are used.

2) Metal-ceramic sealing element.

In order to strengthen the very movable “body-shaft” connection, a double mechanical seal is used, where the movable and stationary rings are made of ceramic. Thanks to the special properties of the material used, friction between the rings is minimized and there is almost no air gap.

Therefore, all guarantees are given for the highest possible tightness and long service life.

3) Installation of the oil seal and additional sealing of connections.

Malfunctions

A high-quality box should contain a pump, inside the box there should be a warranty card with stamps and the date of manufacture and a gasket. It is mandatory to have a holographic sticker on the pump.

Factory service life of the pump

The service life of a water pump depends on the supplier of the product or, in other words, on the build quality of the pump, the elements and materials used. A not quite high-quality pump can fail even after 10 thousand kilometers of the car. The service life of a good part can be 100 thousand kilometers without any signs of failure of the part.

Experts recommend installing an original water pump on the car from the manufacturer TZA (Tolyatti Automotive Unit Plant), which has good quality and a significant period of trouble-free operation.

The main function of this part is to ensure intensive circulation of coolant (coolant) through the engine's fluid circulation system. Thanks to this constant movement, the temperature of the liquid decreases and its ability to cool other parts and systems of the car is restored. As a rule, the water pump on a car engine is structurally located in front of the cylinder block.

When to change your pump

A clear sign that the pump needs to be replaced are the following points.

1. In the warm season, there is frequent overheating of the power plant, although there is enough antifreeze in the expansion tank.
2. Leaks appearing at the pump connections. Failure can be detected by fogging of the case or the presence of wet spots of a characteristic composition.
3. Extraneous noise coming from the pump when the engine is running - it can be knocking, rustling or crackling.
4. In winter, the heater stops working even when the engine is normally warmed up.

You should also consider the service life of the part on a particular vehicle. For most cars, the operating time of the device ranges from 60,000 to 90,000 kilometers. In some cars, this gap can reach 120,000 km. The manufacturer recommends replacing the pump before its service life expires.

Thermostat

Next you need to go to the thermostat. "Priora" (16 valves), in which replacement of the thermostat itself does not need to be replaced, remains as before not running. The next step is to remove the temperature sensor from the element body. It is used to control the temperature of antifreeze. Now, of course, loosen a few fixing bolts and freely pull the thermostat out. The sealing gasket is removed from the studs.

Its drive is carried out from the crankshaft through a special wedge-shaped belt or from the gas distribution mechanism (timing) using a toothed belt.

A special toothed belt ensures the functioning of the car's water pump.

General pump structure

The Lada-Priora pump is a fairly simple mechanical unit, which consists of several main parts.

The pump design consists of several elements, one of which is the obligatory gasket

The main components of an engine water pump are:

• product body;
• a shaft with an impeller and a special self-regulating oil seal, thanks to which the coolant is securely retained in the structure during operation;
• pump shaft bearing on which the pump shaft is mounted;
• drive pulley;
• radiator fan (this part can be attached to the pump drive or in a separate electric drive version, without any connection with the car’s water pump);
• gasket made of cardboard or special material.

Operating principle of the device

The operation of the coolant pump is as follows:

• with the engine running, the coolant that has cooled in the car radiator moves to the pump (in particular, to its impeller);
• the gaps between its blades are completely filled with coolant;
• due to the action of centrifugal force, the coolant is thrown by the impeller into different directions of the internal cavity of the HV;
• through the technological hole, the liquid goes into the channels of the cooling jacket of the motor elements;
• constant circulation of the cooling medium in the liquid cooling system is ensured.

Design Features

To prevent possible leakage, the pump body is installed on the engine cylinder block through a special gasket (for example, made of cardboard). The cooling fan, which is sometimes structurally located on the car pump pulley and driven simultaneously with it, is usually made of metal or durable plastic. To reduce operating noise, the blades of the structure are located at certain angles, in an X-shaped position, which corresponds to 110/70 degrees.

In order to reduce the power required to drive the fan, designers use a special electromagnetic clutch. This device can turn off the fan when the coolant temperature drops to a level of 78–85 degrees Celsius. In this way, the operation of the engine cooling system is optimized, and the noise level during operation of the unit is also reduced.

Tips for choosing pumps for Lada Priora

In the line of any brand there are pumps for different car models, differing in dimensions and design features. When choosing a water pump, you need to take into account the mounting dimensions and materials from which the part is made.

The pump body for cars is made of aluminum. The metal does not corrode and is easy to shape into any shape. Manufacturers most often choose steel for the shaft so that it can cope with the load from bearings, seals and impellers.

Impeller. One of the most important elements of a water pump, on which the performance of the pump depends. It comes in cast iron, other metal and plastic. The cast iron part is durable, but heavy and has thick blades, so its efficiency is inferior to others. Metal is lighter and more efficient, but is susceptible to corrosion. Plastic is the lightest material. Such an impeller is productive, but over time, due to contrasting temperatures, it becomes fragile and begins to slip.

The impeller on the back side of the impeller relieves the shaft-housing seal. Not available on all models, but it helps to increase the efficiency of the pump and increase its service life.

Should I change antifreeze after replacing the pump?

A question for those who want to save money everywhere and on everything. If I answer this briefly, I can confidently say that yes, the coolant needs to be changed. Please also pay attention to the question regarding mixing antifreeze in the cooling system. It will be useful and important to know all the nuances.

If we talk about the necessity of replacement, then everything is extremely simple. To begin with, in the vast majority of cases it is impossible to replace and remove the pump without first draining the antifreeze from the system. But some people want to save money; they drain the coolant into a clean container, install a new pump, and then pour the old antifreeze back in.

A big mistake, since any water pumps for cooling systems are characterized by increased demands on the quality and purity of the liquid. Therefore, you should absolutely not use previously drained antifreeze, even if you just recently changed it, even before the pump failed. Do not attempt to filter or strain the coolant. Just buy a new can of quality antifreeze that is suitable for your car and fill it up. There simply cannot be any other options. Remember this. Otherwise, you will soon have to spend money on a new pump again.

To ensure that the water pump lasts as long and reliably as possible, make it a rule to use only high-quality compounds. As you remember, 90% of pump failures are related precisely to the quality of the coolant used. I think it will not be difficult to draw the appropriate conclusions.

Installation instructions for an additional electric pump

Installing an additional water pump on any car (including the Lada Priora has 16 valves) is, in principle, no different. It is necessary to place the electric pump in the section of the pipe, which is the input or output to the car’s stove and provide its power supply.

Step-by-step instructions for installing this additional component are as follows:

1. Provide access to the heater pipes under the hood of the car by removing components that interfere with operation.
2. Compress one of the rubber pipes that comes out of the heater (stove), which is done to prevent coolant from leaking out, or drain antifreeze (antifreeze) from the entire system.
3. Cut part of this pipe to the length of the corresponding pump being installed.
4. The length of the fittings is not taken into account due to the fact that they fit into the pipes.
5. It is necessary to select the diameter of the fittings on the electric pump in advance to obtain a high-quality connection.
6. Secure the rubber pipes to the pump fittings using metal clamps.
7. Attach the additional electric pump to a pre-selected location under the hood of the car (indicated above) using special fasteners.

   
   An additional electric pump can be mounted in any place convenient for installation.

8. Connect the power supply to the pump by selecting the options listed above, or install a separate switch.
9. Start the engine and check the tightness of the connections, as well as the functionality of the electric pump.
10. Install all parts that were removed before installing the pump.

It is recommended to install such a pump only after a thorough check of the functionality of the entire cooling system of the car, since there are often faults in the stove, thermostat, and other components, which ultimately does not allow sufficient heating of the interior.

The water pump of the Lada Priora car is designed to maintain the internal thermal conditions of the car's power unit set by the manufacturer. Operating a motor with a faulty pump is guaranteed to lead to more serious breakdowns and, as a result, to significant financial costs. Timely replacement of a failed water pump will ensure a long service life for the engine, as well as comfort when using the car.

How to determine the need to replace your pump

Replacing the Priora water pump. Warning! Do not turn the crankshaft or camshaft after the camshaft drive belt has been removed, otherwise the piston may hit the valves. Wear of the pump bearing (indicated by increased noise during operation) and leakage of coolant from the pump are the main defects of the water pump.

As a rule, repairing the water pump does not lead to the desired result, so it is recommended to replace the pump assembly. Replacing the pump is a procedure for performing actions that you can do yourself.

Description

Water pump Luzar

In this case, the camshaft pulley must be installed with the protruding part of the hub facing the engine. Then you need to check the alignment of the top dead center marks on the rear drive belt cover and the camshaft pulley. The last step is to adjust the tension of the camshaft drive belt, and only after that add coolant.

Of course, the TZA pump is in greater demand than the Luzar and is considered more reliable and of higher quality. The main cause of belt breakage is usually considered to be the pump, but the catch may lie elsewhere. The reason may be the coolant, which is poured at the factory of poor quality, and after 20-25 thousand mileage it almost loses its ability to lubricate the pump seal.

A water pump can fail for two main reasons - wear of the bearing or oil seal. When the bearing wears out, a distinct hum will be heard, which is a sign that the bearing is humming and the pump needs to be replaced. If a pump with a faulty bearing is not replaced in time, this can lead to it jamming.

The second reason for pump malfunction is leakage from under the seal. If you notice that your antifreeze or antifreeze has begun to run out, one of the reasons is precisely the pump. Check for fluid leaks in the area where the pump is located.

If so, the pump is most likely leaking. In this case, operating the car is not advisable, but is possible provided that you have to constantly add coolant.

Another sign of a pump malfunction is a worn timing belt. If the bearing is broken, the pump may “walk” slightly, which will cause the belt to eat up, and as a result, the timing belt may break and then you will have to deal with the capital of the motor, since the valves will bend.

When choosing a pump, be sure to purchase one that is suitable for your motor. A pump for a 16 valve engine is not suitable for an 8 valve engine. The difference in replacing the water pump is that on an 8 valve engine there is 1 pulley, and on a 16 valve engine there are 2 pulleys. . By the way, from this article you can learn how to replace the fuel pump on a Lada Priora.

Before you begin removing the pump, you will need to drain the coolant. We find the drain plug, substitute a container with a volume of about 4 liters and drain.

After draining the liquid, remove the upper decorative cover, the alternator belt, and then the front timing cover, it consists of two parts.

Now you need to set the timing marks so that during assembly you do not make a mistake with the ignition setting.

Next, unscrew the pulleys. To prevent the pulley from turning, engage 5th gear and press the brake. Now the pulley will be motionless, you can safely unscrew it. Unscrew the pulley bolts using a 17mm spanner.

If you have a car with air conditioning, you need to use a 13 mm socket wrench to unscrew the bracket for the generator belt tensioner pulley and air conditioner with steering wheel.

The next step is to remove the crankshaft pulley. To do this, remove the right front wheel and mudguards. Next, engage 5th gear again and press the brake. The pulley will be fixed and can be safely unscrewed. Remove the pulley and timing belt.

Next, unscrew the 6 bolts securing the cover and then carefully remove it from the engine.

We unscrew the 6 bolts securing the pump, carefully pry it up with a screwdriver and pull it out. When installing a new pump, it is necessary to coat the gasket with a thin layer of sealant and screw the pump into place. Next, we reassemble in the reverse order, taking into account the timing marks.

Signs that indicate the need to replace a part

Experts believe that the main factors that indicate a faulty water pump are:

• coolant leaking from the housing in the oil seal area;
• wear of the built-in bearing, which is determined by increased noise, humming during operation, or jamming;
• insufficient circulation of the coolant used;
• excessive increase in the temperature of the power unit;
• reducing the level of coolant poured into the system;
• the presence of cracks, chips, chipping of the material of the pulley, housing or impeller of the water pump.

The water pump, as a rule, is a non-repairable component due to its design. Therefore, experts recommend a complete replacement of this important part.

The water pump for the Lada Priora is completely replaced if it malfunctions

Algorithm for replacing a VAZ Priora pump 16 valves

First of all, we need to disconnect the terminal from the battery in order to carry out the entire operation without any consequences. Then remove the crankcase protection. To do this, you need to unscrew the bolts and hexagons. Nearby is a plastic shield for the right fender liner.

Draining the antifreeze

The next step is to drain the antifreeze from the block itself. Or unscrew the starter mounts and move it aside, then drain the antifreeze.

Removing the timing belt cover

Next is the plastic cover, which comes off quite easily, just pull it up. You will now see the belt housing that turns the crankshaft. You unscrew it with 30mm Torxes. But due to the fact that the space is limited in size, you will have to use a corner. The casing consists of two parts, which can be removed separately and without any difficulty.

We place marks on the shafts

After this, we set the piston of the first cylinder, where the TDC-1 mark will be. This is the compression stroke. Then look closely and you will see a mark in the form of a dot on the crankshaft. You need to align it with the low tide mark, which is located near the oil pump. But don't forget about the camshaft. Align its marks with the marks that are located on the belt casing itself.

Removing the timing belt

After setting the marks, you can remove the belt. To do this, relax the rollers and carefully remove the belt so as not to tear or stretch it. The videos will also need to be removed. At this stage of the process you will have to remove the cast iron casting, otherwise you will not be able to remove the casing. After this, remove the part that was inside the plastic casing. It is held in place by five bolts.

Removing and installing a new pump

And now, finally, we can begin to directly replace the pump. To do this, use a hexagon to unscrew the bolts and begin to gently rock the pump in different directions. When it loosens, remove it. Lubricate all parts immediately with oil. Check the gaskets.

Reassembly requires care and precision. Install everything in reverse order and be sure to ensure the correct alignment of the marks. After that, install the belt. Then rotate the crankshaft twice. If everything went well, then we put the remaining parts in place.
