The average service life of a water pump (pump) on a Lada Grant does not exceed 80,000 km, although the operating instructions indicate an interval of 120,000 km. For domestic cars, a pump service life of over 85,000 km is nonsense.
In the event of a breakdown, you can replace the pump on the Lada Grant yourself, without resorting to the help of service station technicians.
Replacing the pump
Where is the water pump on the Lada Granta?
Regardless of the modification of the technical device, the number of preinstalled valves, the water pump is installed in the engine compartment. From the end of the engine, below, closer to the crankshaft pulley.
If maintenance and replacement are necessary, the pump is dismantled along with the drive belt and crankshaft pulley.
Remove the pump through the opening in the wheel arch of the car, after jacking up the right side of the car. Some service station technicians practice dismantling through the top of the engine compartment, depending on which is more convenient.

Description of the replacement process
Grants are equipped with eight and sixteen-valve engines. The water pump is located under the timing belt casing, and therefore when dismantling it, both casing covers, the belt, the tension roller and the crankshaft pulley are removed. The slight differences in the procedure for changing the pump for an eight- and sixteen-valve power unit lie in the different methods used when dismantling and subsequently installing the timing belt, which will be discussed in more detail below.
The cost of the pump varies from 1000 to 2000 rubles. For 1000 rub. the owner of the Grant will be able to purchase a water pump manufactured at AvtoVAZ. More expensive pumps are imported analogues that have an increased service life. In addition, there are also pumps on the market that cost from 500 to 700 rubles, but most often they are sold by not very conscientious sellers who pass off their product as an original, which it actually is not. Installation of such parts is highly undesirable.
It is also worth noting that when purchasing a new element, the car owner should focus on the type of engine for which this part is intended, since pumps for 8- and 16-valve Grants are not interchangeable. There are markings on the pump packages that allow the buyer to select the part that is suitable for his type of motor.
Preparatory stage
Required materials and tools:
- set of automotive tools;
- heads, ratchet;
- rags;
- additional lighting;
- screwdrivers with a flat, cross-shaped bit;
- hydraulic jack.
Preparing for replacement
Checking the condition of the water pump
Checking the pump on a car is not that difficult. First, you need to warm up the engine so that it reaches operating temperature. After this, follow these steps:
- Pinch the upper pipe at the radiator outlet with your hand. When the pump is working, you will feel the pressure it creates. Be careful during this task as coolant temperatures are typically 90°C or more. If the antifreeze in the system does not pulsate or the pulsation is barely felt, perform a more detailed check.
- It is necessary to remove the timing mechanism protection and inspect the pump visually. Sometimes coolant leaks, which can be caused by a damaged seal, are immediately visible. In addition, signs of pump malfunction may include grayish or red-colored deposits in the area where it is located. In this case, the part will have to be removed.
- If you hear the characteristic sound of a faulty bearing while the motor is running, you need to check the pump for play in the shaft area. Just rock the pump drive gear. Sometimes everything is “cured” by simply replacing the bearing.
Malfunctions and troubleshooting methods
| Symptoms of a problem | Remedy |
| The operation of the unit is accompanied by noise, hum, and metallic creaking.. | Dismantling the pump, carrying out comprehensive diagnostics. Replace worn parts as needed. |
| In the area where the water pump is installed, traces of antifreeze leakage, system depressurization, and gasket damage are visible. | Dismantling and replacement of paronite gasket. |
| Weak circulation of antifreeze in the expansion tank. | Deformation of impeller blades and pump pipes. |
| When there is a mechanical impact on the pump pulley, bearing play is heard. | Dismantling, checking and replacing the roller bearing. |
Installing a new timing belt
We take out a freshly purchased set.
Timing kit.
Important! The tensioning direction is indicated on the timing belt tension roller, do not confuse it.
Tension direction.
We check that all marks match and install the tension roller; do not tighten the bolt. We install the new timing belt first on the crankshaft sprocket, then on the camshaft, tension roller and pump. The belt section between the camshaft and crankshaft sprockets must be tensioned. Pull the tension roller until the marks match and tighten the bolt.
Correct tension.
Once again we check that the marks match, after which we turn the crankshaft two turns and check the tension. If the tension is weakened, tighten it.
Installed belt.
We install all parts in the reverse order of removal. Fill with antifreeze. That's all! By the way, the engine is identical to that installed on the second generation Kalinas; replacing the timing belt on them is described in this article.

Reinforced pump Luzar for Lada Granta 2190
Luzar Turbo 2 is a high-power water pump for the Lada Granta. The average cost in the Russian Federation is 650 – 750 rubles, depending on the place of purchase. Pump flow rate at 800 rpm is 900 l/h. The unit runs 95 – 120 thousand km.
The installation of a turbo version of the pump is explained by the fact that the engines of the Lada line are prone to rapid boiling and an increase in operating temperature.
The temperature increases according to the following scheme: the car moves at high speeds on the road. A sudden stop at a traffic light provokes a rise in temperature, heat stroke, and boiling of antifreeze.

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:
- Provide access to the heater pipes under the hood of the car by removing components that interfere with operation.
- 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.
- Cut part of this pipe to the length of the corresponding pump being installed.
- The length of the fittings is not taken into account due to the fact that they fit into the pipes.
- It is necessary to select the diameter of the fittings on the electric pump in advance to obtain a high-quality connection.
- Secure the rubber pipes to the pump fittings using metal clamps.
- 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.

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.

Types of cooling systems
There are three types of automotive cooling systems:
Air systems are open type systems. They remove heat from heated engine parts with a directed air flow. The liquid system is of the closed type. It removes heat using antifreeze that continuously circulates in the engine cooling jacket. Combined systems combine both liquid and air cooling methods. The vast majority of modern passenger cars, both diesel and gasoline, are equipped with liquid cooling systems. They are used for two reasons:
- high efficiency;
- minimum noise level.
Basic elements of liquid cooling systems for cars
The liquid cooling system of any modern car consists of the following elements:
- engine cooling jacket;
- thermostat;
- central radiator with fan;
- oil radiator;
- stove radiator;
- expansion tank;
- cooling pump.
The cooling pump can rightfully be considered the main element of the automotive cooling system. After all, without this device, all other parts of the system simply will not be able to function, and any malfunction of the unit entails overheating of the motor and its failure. Therefore, let’s take a closer look at the water pump.

Pump design
The pump body is made of steel or aluminum, and inside it there is a shaft with a pulley on which the impeller is located. Also inside the pump you can see channels for supplying and discharging coolant. The rotation of the impeller ensures optimal fluid circulation in the system.
Have you already read our article about how different colors of antifreeze differ and whether they can be mixed? The information is quite interesting - https://avtopub.com/antifrizyi-raznyih-tsvetov/
Many cars have pumps whose impellers and casings are made of alloys of various metals, but there are also impellers made of plastic. You can find the pump at the front of the engine.

Recommendations for the selection of parts and components
Considering that the service life of domestic water pumps is limited, service station technicians recommend purchasing foreign analogues. The cost of imports is 10–15% more expensive, however, the service life is 15–20 thousand km longer.
To avoid buying counterfeits, use the services of trusted stores, suppliers, and Internet sites.
Strictly follow the manufacturer's requirements for the timing of technical inspection. Check the catalog numbers with the actual data in the operating instructions.
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.
Reviews

| 1. | Vladimir: I replaced the pump bearing for the first time at 85,000 km. I think that the mileage for domestic transport is very good. I carried out the replacement myself and did not contact a workshop. |
| 2. | Kirill: during two years of active use of the car, he once made an unscheduled visit to a service station to replace the paronite seal. |
| 3. | Vasily: I’m pleased with the quality of workmanship of the Lada Granta, there are no complaints. The first time I replaced the water pump was at 80,000 km. This is a good indicator for domestic transport. I bought a Spanish pump from Doltz at the store. The minimum service life is 120,000 km. |
| 4. | Ivan: I’ve been driving the car for a year and a half, I have no complaints, all the mechanisms work properly. I heard negative reviews about the Lada Granta regarding its build quality. I can’t confirm, I recommend buying a car. |
| 5. | Gennady: at 85,000 km I replaced the water pump for the first time, I didn’t contact the service center, I did it myself. The store offered FENOX HB1001C3, cost 650 rubles. Two months have passed since installation, no complaints. |
| 6. | Dmitry: six months of active operation of the machine, all mechanisms work properly, no comments. Once I visited a service station unscheduled to tighten the drive belt. |
| 7. | Alexander: I’m pleased with the build quality of the domestic car. Minor breakdowns happen, but how can we live without them? Since I know a lot about cars, I fix most of the defects myself. People contact the service only for routine diagnostics. |
| Negative | |
| 1. | Vitaly: the pump failed for the first time at 45,000 km, replaced METELLI 24-0833. The work was carried out at a service station under a factory warranty. The quality of domestic parts is low; it’s better to pay a few hundred rubles extra and purchase a foreign analogue. |

Tuning Lada Granta: bringing the car closer to ideal
Who to pay attention to
As a standard, VAZ cars are equipped with a pump manufactured by TZA. It is relatively good and can last quite a long time, but not all users are satisfied with its quality. An alternative solution could be Luzar. A trusted manufacturer that supplies pumps that are ideal for AvtoVAZ products. If you need a pump for a long time, Luzar may be a good solution.
If you prefer devices from foreign companies, it’s time to stop at SKF. A good option, characterized by an excellent price-quality ratio. Please note that you should not buy HEPU products. Its pulley is simply not suitable for Priora cars. A cheap but short-lived option would be Coram. This is a Chinese company that supplies inexpensive but very mediocre pumps.
