Today we will tell you how to choose the right coolant pump, what to look for, and find out what experienced VAZ-2112 owners advise. After diagnosing various forums, we compiled a rating of all pumps that are popular among VAZ-2112 car enthusiasts and compiled a rating that can fully reveal all the advantages and disadvantages of each model.
The video explains how to distinguish an original pump from a fake, and what to look for when choosing this part:
Previously, we wrote about how to check the pump for functionality and how to replace it yourself.
Why do you need a pump?
If the information has reached an experienced motorist, you can safely skip this section. For beginners, before telling which pump is better to install on a VAZ, you should explain what it is and why it is needed.
The main task of the mechanism is to ensure proper circulation of antifreeze throughout the cooling system. If the design works correctly, the liquid maintains a stable temperature, and thermal shock due to sudden heating of the block when the speed increases is eliminated.
The pump also ensures normal operation of the stove. With good system circulation, the radiator quickly releases heat into the interior.
If the pump is missing, the motor will instantly overheat, which will cause its damage or complete destruction. A similar result occurs when it breaks.

FENOX
FENOX pump
- Manufacturer: Republic of Belarus.
- Retail price: 300-350 rubles.
- The pump from the manufacturer FENOX is one of the cheapest on the market. At low speeds it can withstand flow, while being able to withstand thermal shock. The workmanship is excellent, the packaging is high quality. The undoubted advantage of this pump is its low price and excellent performance with high crankshaft rotation speed. Among the minuses, users note the presence of red spots on the impeller after this pump has been in operation. One can only guess about their origin.
WEEN
WEEN pump.
- Manufacturer: European Union.
- Retail price: 400-450 rubles.
- The six-blade impeller, made of aluminum alloy, like its predecessor, is relatively inexpensive. The good quality of the impeller casting and stable operating characteristics adequately leave this model in fourth place with the caveat: the ideal price-quality ratio of the model.
HEPU
HEPU pump.
- Manufacturer: Germany.
- Retail price: 750 rubles.
- Of the entire rating, the pump has the highest price. Despite the fact that it has only six blades made of cast iron, the performance is the highest compared to analogues. The model shows significant performance, build quality and overall neatness. The performance characteristics also evoke positive emotions among users. This model takes third place, as it is equipped with only six blades and cannot compete with the winners of this rating.
Luzar
Luzar pump.
- Manufacturer: Russia.
- Retail price: 500 rubles.
- The pump is equipped with a seven-bladed aluminum impeller, which shows high flow characteristics, a fairly large margin of reliability and quality workmanship. Instead of the pump itself and the gasket, the delivery set also includes new mounting bolts, which will only please the consumer.
TZA
TZA pump.
- Manufacturer: Russia.
- Retail price: 500 rubles.
- The second model that took first place in our rating is a model from TZA. This pump is supplied to VAZ-2112 cars directly from the factory. Despite the fact that the impeller is made of plastic, no contraindications were found for this. It, like its analogue from Luzar, showed high performance during operation and was distinguished by high reliability, quality of manufacture and assembly.
When to change your pump
A clear sign that the pump needs to be replaced are the following points.
- In the warm season, there is frequent overheating of the power plant, although there is enough antifreeze in the expansion tank.
- 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.
- Extraneous noise coming from the pump when the engine is running - it can be knocking, rustling or crackling.
- 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.
Replacing the water pump on Grant (8 valves)
The driver can change the pump on an 8-valve Lada Granta without going to a service station. The main thing is to follow the replacement instructions and, upon completion of the replacement, set the crankshaft and pulley values correctly. Usually, along with the water pump, it is customary to change the timing belt.
Where is the pump located?
Since the pump is put into operation by a gas distribution mechanism, it is quite obvious that it will be built into the timing system. That is, you need to look for the location of the pump on the Lada Granta on the right side of the engine.
It is impossible to visually see the pump before removing the timing belt - only the pump pulley is visible, which is what starts the impeller into operation.
The water pump is included in the timing belt assembly
Preparing tools
To work, you will need several wrenches, standard auxiliary tools and materials:
How to choose a pump for a VAZ
There are several signs that determine the correct choice of pump for a car. Moreover, each parameter is taken into account individually - there is no universal method.
The pump impeller can be:
- plastic;
- metal.
The first option has the advantage of having no inertial load, which makes it easier to unwind when the motor starts. The downside is the short service life and changes in the geometry of the wings under the influence of high temperatures - this reduces the efficiency of the pump. New foreign cars are equipped with impellers made of expensive materials that can withstand overheating and cavitation abrasion.
The second type is made of metal. Such impellers are heavier, take a long time to spin, but do not change geometry when heated. On the other hand, steel parts quickly become corroded when the wrong antifreeze or water is used in the cooling system, which critically reduces their performance.
According to the design, you should choose impellers with a minimum gap between the housing and the blades. This combination minimizes idle rotation of the mechanism and increases the efficiency of the unit.
The manufacturer recommends using parts of the same brand. If such pumps are not available, you should study reviews of the available company in advance and choose the best one at your own discretion.
Differences in pump production technology
Signs of a fake pump. This is clearly not the famous Gates. That's why we didn't include it in our rating, there are too many fakes.
Pumps are produced with six and seven blades; they differ in manufacturer and technical characteristics. According to various tests carried out, those models with seven blades perform much better during operation than its limited counterpart. Below we will present you with a rating of the five best pumps, the performance of which varies in the same range.
Which pump is better for a VAZ car
The following is a list of popular market offers that are in great demand among domestic car enthusiasts. The top manufacturers are based on their prevalence in stores across the country and the frequency of their purchase. At the same time, some brands produce a limited number of modifications, which negatively affects popularity.
FENOX
The rating of pumps at VAZ opens with an extremely well-known organization in certain circles.
The brand produces a large number of spare parts for classic and modern VAZs. When choosing which pump is better to install on a Niva, a classic or a new one, sellers often recommend installing the Phenox. The company has production sites in the CIS countries and is focused on producing parts for “local filling” machines, which allows them to fully meet the requirements of manufacturers.
In 2022, brand pumps are not widely used due to their low cost and short service life. But with moderate driving and use of classics, the products show their best side.
Advantages:
- minimum cost;
- well-known company;
- good efficiency.
Flaws:
- there are defective pumps;
- a lot of fakes.
METELLI
The top popular company continues, whose production facilities are mainly located in Poland.
The brand supplies pumps to the domestic market as replacement and original parts mounted on assembly lines. Due to the high quality of products, auto giants like Ferrari, Fiat and Peugeot order products from the manufacturer and put their logo on them. Special quality control is emphasized - all pumps undergo rigorous tests and comply with the international standard ISO 9002, which guarantees their long-lasting operation. The second important factor is the almost complete absence of counterfeits - mechanisms are supplied mainly to official dealers or trusted stores. Therefore, when asked which pump is best to install on Kalina or a similar model, you can safely contact the company for a new part.
Among customer reviews, there are mostly positive comments, but there is also a small share of negativity.
Advantages:

Also in the company's assortment you can find a wide range of pumps for other classic or modern cars. The brand has been operating since 1934 and is a reliable company whose reputation has been proven over the years. The manufacturer focuses its attention exclusively on pumping equipment installed on trucks and cars, which allowed it to create extremely high-quality devices.
Thanks to its narrow focus, the manufacturer makes pumps for 95% of European cars. At the same time, without losing the quality of the products.
The notorious reliability of parts is due to the use of patented technology. The alloys used in the impellers are resistant to mechanical abrasion and cavitation wear, which eliminates the pouring of low-quality antifreeze or water into the cooling system.
Advantages:
- wide use;
- large selection of modifications;
- good protection against counterfeiting;
- long service life.
Flaws:
- price.
SKF
The next representative of the rating, originally from Sweden, has a large number of production sites throughout Europe and the CIS.
Therefore, when choosing products, you should not get hung up on the country of origin - thanks to strict quality control, the products turn out to be of good quality, regardless of the place of manufacture. The popular brand is in demand among domestic motorists due to its decent quality and reasonable cost. When asked which pump is better to install on a VAZ 2114 or its equivalent, you can safely buy a brand-name device. According to drivers, the pumps last up to 130,000 kilometers, which exceeds the performance of analogues by 20-30%.
Significant disadvantages of the brand's products include the abundance of copies on the market. Due to their widespread use, pumps are often counterfeited, which forces buyers to carefully select kits. The manufacturer insists that the original part is equipped with the mark of the assembly shop and markings on the box. If one of the elements is missing, the buyer is faced with a fake.
Advantages:
- sufficient level of technology;
- excellent quality of parts;
- moderate price tag;

Flaws:
- A large number of fakes.
HEPU
If you need a good pump for an old or new generation Niva, experienced experts advise purchasing products from the brand described.
The main difference between the brand and its analogues is that the manufacturer has its own research center that studies metal corrosion processes, which allows them to quickly make changes to the structure of the materials from which parts are made. Natural product tests indicate a pump life of up to 90,000 kilometers, with average intensity of vehicle use. On the other hand, on display cases there are problematic mechanisms with a lack of lubrication in the bearings or minimal play in the main shaft.
The result of the work of engineers is high-quality pumps that can operate for a long time under moderate loads.
Advantages:
- sufficient reliability of the design;
- widespread throughout the CIS countries;
- reasonable price.
Flaws:
- There are defective parts.
BOSCH
The next representative of the top, indicating which is the best pump for Vesta, comes from Germany.
The famous brand is engaged in the production and improvement of unique products of the highest quality. The brand's controversial reputation is due to the presence of production facilities around the world. For example, at Russian factories, manufacturing standards and rules are softer than in Germany, which causes a drop in quality. Therefore, when purchasing a pump, you need to pay attention to the country of manufacture and choose products with a European logo.
Also frankly “stressful” is the abundance of counterfeit products. There are often surrogate pumps on the market, which is a consequence of insufficient copy protection.
Advantages:
- excellent workmanship;
- long service life;
- wide choice of modifications.
Flaws:
- abundance of fakes;
- often controversial quality;
- It is recommended to buy only European pumps.
VALEO
The next representative of the list is a world-famous brand that is a supplier of parts for famous automakers and their assembly lines.
The main advantage of the company's pumps is that they are delivered to the customer along with guide rollers, timing belt and all gaskets. Such “stuffing” ensures reliable operation of components for 150,000-180,000 kilometers. If you buy an original set, the high cost is fully compensated by its durability. Therefore, when asked which pump is better to put on Vesta or something similar, you can safely turn to the brand. The only caveat when purchasing is careful selection - a large number of counterfeits are produced for the manufacturer’s products, which slightly overshadows the positive customer reviews. Also, drivers should not be confused by the brand of the Russian plant - the brand has a production site in the Nizhny Novgorod region.
Advantages:
- long service life;
- withstand severe overloads;
- a wide range of;
- excellent package.
Flaws:
- a large number of fakes;
- high cost of the original.

Basic faults
Signs of a faulty pump are:
- hum or rustling in the timing drive area;
- leakage of coolant from the pump seat;
- mechanical damage to the timing belt (eaten teeth, delamination, cracking).
The main malfunction of the coolant pump is the failure of its bearing, which can be caused by its wear or incorrect adjustment of the timing belt tension. If this problem is detected, the pump must be replaced.
It is recommended to change the pump along with the timing belt and tension pulley every 50 thousand km, as well as when signs indicating its failure are identified. If the coolant pump is not replaced in a timely manner, this can lead to:
- damage and breakage of the timing belt, as a result of which it will be necessary to repair or change the cylinder head along with the gas distribution mechanism, as well as parts of the piston group;
- overheating of the engine, which can lead to damage to the rubber communications of the cooling system, cylinder head gasket and valve cover, and piston group parts.
The price of a pump for an eight-valve VAZ 2110 engine is 700-1000 rubles. The cost of repair work at a service station is about 1000 rubles. But you don’t have to overpay for the work. You can replace the pump yourself.
When purchasing a pump, be sure to pay attention to:
- manufacturer of the spare part (under no circumstances buy parts from unfamiliar brands);
- catalog number of the spare part (the standard pump for the eight-valve engine has the number 21081307010);
- presence of original packaging;
- gasket included;
- Availability of a warranty card for the product.
