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.

| When there is a mechanical impact on the pump pulley, bearing play is heard. | Dismantling, checking and replacing the roller bearing. |
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.

Replacing Lada Granta struts with your own hands. Recommendations from professionals
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.
| Characteristic | Indicators |
| Material | Poly Phenylene Sulfide |
| Strength | up to 210 M Pa |
| Elasticity | up to 21,000 M Pa |
| Impact resistance | up to 51 kJ/m2 |
| Stability under load | Yes |
| Performance | -60 to +220℃ |
| Resistance to hydrolysis | 0,03% |
| Low shrinkage | Yes |
Checking the functionality of the water pump
Self-diagnosis of the pump is quite simple and will take no more than 10 minutes. The verification procedure is as follows:
- The engine warms up to operating temperature (91˚C for VAZ 2110).
- For safety reasons, a thick glove is worn on the right hand.
- The coolant supply from the radiator is cut off. To do this, squeeze the pipe by hand. If the pump is working properly, you will feel the antifreeze pressure inside the hose. If the pipe compresses easily, then the pump is faulty.
All actions should be carried out with extreme caution, since the coolant gets very hot, and you can get burns from the surface of the motor or pipes.
To identify problems with the pump, it is enough to pinch the coolant supply pipe
Diagnosis of pump faults on VAZ 2110/11/12
A pump malfunction can be identified by the following signs:
- While driving, extraneous noise appears from the timing belt.
- The pump loses its seal and begins to leak.
- The timing belt breaks.
The most capricious element of the VAZ 2110/11/12 pump is the bearing. If it is severely worn or if the timing belt tension is incorrect, the pump cannot be repaired.
One of the symptoms of a pump malfunction is the appearance of a leak.
Consequences of using a faulty pump
Operating a car with a faulty pump can lead to the following serious consequences:
- damage or breakage of the timing belt, often leading to a major engine overhaul;
- When the engine overheats, the rubber elements of the cooling system, valve covers and cylinder head gaskets are destroyed.
The pump is changed along with the tension roller and timing belt every 50 thousand kilometers. If signs of wear appear, these components are replaced before the time specified by the manufacturer.

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
| № | Positive |
| 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. |
| 2. | Dmitry: Over the two years of driving a car, I have repeatedly contacted the service station for repairs and replacement of defective units. I don’t recommend buying domestic vehicles; pay a few tens of thousands extra and buy a Renault Logan. |
| 3. | Ignat: I drove 65,000 km, and already managed to replace the water pump. The mileage is too low due to the poor quality of parts and components. |

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.
