Pump VAZ 2107

On cars with a liquid cooling system, including the VAZ 2107, one of the main elements responsible for maintaining the operating temperature of the engine is the pump. Thanks to this unit, the circulation of coolant is ensured. If problems arise or if the water pump fails, the normal operation of the power unit is disrupted, which can lead to serious consequences and expensive repairs.

The pump circulates coolant through the engine cooling system

Purpose

The operation of the pump is aimed at continuous circulation of coolant (coolant) through the engine cooling jacket. The antifreeze is heated under the influence of the rubbing elements of the power unit, and the necessary pressure in the system is created by a water pump. The liquid is directly cooled in the main radiator, after which the coolant again enters the cooling jacket. If circulation is interrupted for at least 5 minutes, the motor will overheat. That is why it is so important to monitor the proper operation of the node in question.

Pump design

On the VAZ 2107, as on many other passenger cars, the pump has almost the same design. The unit consists of a housing with a central shaft located inside, on which the impeller is fixed. The shaft is secured against axial displacement by means of a bearing, and the tightness of the structure is ensured by an oil seal that prevents coolant leakage. There is a hole in the pump cover through which the shaft comes out, where the pulley hub and then the pulley itself are attached to it. A belt is put on the latter, which on the “seven” rotates the generator and pump from the crankshaft. On modern cars, the pump rotates via a timing belt.

The main elements of the pump are the housing, shaft with bearing, impeller and oil seal

Where is

On classic Zhiguli models, the pump is located on the front of the power unit and is attached not to the block, but through a separate housing. By opening the hood, you can easily notice both the pump pulley and the assembly itself.

The pump is located in the front part of the engine and is part of the cooling system of the power unit: 1 - supply pipe to the cabin heater; 2 - expansion tank; 3 - radiator; 4 - pump; 5 — thermostat; 6 — manifold heating tube; 7 — return pipe from the cabin heater

Which pump is better

For the VAZ 2107, water pumps with catalog numbers 21073–1307010, 2107–1307011–75 and 2123–1307011–75 are suitable. The last two options have an enlarged impeller and a slightly reinforced structure. Initially, these pumps were produced for Niva. The slightly higher cost of such pumps is fully justified by the better performance.

On “Sevens” equipped with both injection and carburetor engines, the same water pumps are installed, and their repairs are carried out in the same way.

The old pump has an impeller made of cast iron, and the new one is made of plastic.

The product in question is produced today by many companies, but the most popular are:

• luzar;
• Hepu;
• TZA;
• Phoenix.

At the car market you can find pumps with impellers made of different materials: plastic, cast iron, steel. Products with plastic impellers, which are equipped with embossed and elongated blades, receive positive reviews. Elements made of cast iron are characterized by lower performance, and as for steel ones, they are susceptible to corrosion and are quite often fake.

The housing is replaced if it is damaged, and in other cases only the pumping part is changed

The pump can be purchased either complete with a housing or separately. If the housing is not damaged, then it is enough to replace the pumping part. If the design has serious flaws or is completely broken, then you cannot do without replacing the housing.

We independently change the pump on a Lada Priora car

One of the most important parts in a car is the pump. It is a pump that moves coolant through the system. If for any reason the pump stops working, this coolant will begin to heat up, which can lead to further boiling.

On a Priora with 16 valves, the pump is considered a part that is often subject to wear.

Manufacturers recommend changing it after 55 thousand kilometers. Sometimes it happens that it lasts longer, and it is changed at about 75 thousand kilometers.

What does it mean about a breakdown?

Signs of a pump malfunction are quite simple to identify, for example:

• coolant leak;
• extraneous noise in the pump;
• backlash;
• leakage of liquid on the pump itself.

If the problem of water or antifreeze leaving the system does not mean immediate repair, then noise and play indicate bearing wear. Such a development of events can lead to dire consequences - the pump may jam. As a result, the timing belt breaks under tension or simply falls off.

In this case, the piston will begin to hit the engine valves, leading to their deformation. The valves themselves bend greatly, damaging the body and working surfaces. This is how the failure of one small part of an adjacent unit leads to an expensive overhaul of the car engine.

Review of water pumps for Lada

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

Double row ball bearing - balls installed on both sides.

Ceramic seal - a friction pair of two rings (moving and stationary) made of various materials (carbon graphites, metals, carbides (tungsten carbide with various bonds, silicon carbide), ceramics (metal oxides), plastics) both of the same material and in combination of various materials (stainless steel - carbon graphite, Al2O3 99% (ceramics) - carbon graphite). To ensure the necessary contact between the rings, a spring, a spring block or an elastic bellows is used.

The distance from the highest point of the impeller to the landing belt - this parameter characterizes the flow: the greater this distance, the better, the smaller the gap between the impeller blade and the mating part of the block - accordingly, suction losses are reduced.

Clarification about LUZAR “TURBO” water pumps

The history of the appearance of water pumps (pumps) LUZAR “TURBO”:

Pursuing the goal of improving the temperature balance of the engine, the LUZAR Company in 2009. began the development of water pumps with increased flow characteristics. It was possible to achieve this goal by optimizing the shape of the pump impeller (impeller). During the development, the impeller used on the pumps of Korean-made cars was taken as a basis.

An additional goal was to improve the resource characteristics (increase service life) of the pump.

The result was the appearance of water pumps 21114-1307010 and 21124-1307010 with a sheet metal impeller with an additionally attached “belt” under the blades (to prevent liquid from “leakage” from the working area).

The following design and technological improvements were applied for the first time in these pumps:

• reinforced ball roller bearings with a roller length of 12mm
• sealing of the “shaft-oil seal” and “housing-oil seal” interface
• additional control of impeller overhang.

Since 2011 These improvements began to be applied serially for all pump models.

The flow characteristics of these pumps are on average 12.5% ​​higher than the characteristics of standard LUZAR pumps (note that LUZAR pumps became the winners of the test of the Za Rulem magazine 06'2009).

Resource characteristics have changed upward by an average of 70% (according to our tests).

LUZAR water pumps with improved characteristics are called “TURBO” - to emphasize the high level of consumer properties (note that this name, in our opinion, has become very successful).

Pump LUZAR “TURBO” 21114-1307010 (brand name LWP 01084)

Pump LUZAR “TURBO” 21124-1307010 (brand name LWP 01124)

Answers to the most frequently asked questions:

Why are these pumps called “TURBO”? Should they be used for "turbocharged" engines?

No, these pumps are intended for regular VAZ cars. The name “TURBO” has an “advertising” purpose.

How are such high consumption rates achieved?

You can increase the flow characteristics of a water pump by changing the shape of the impeller (impeller). The most important parameters of the impeller, on which the efficiency of the pump depends:

1. Diameter of the impeller 2. Shape of the blades 3. Thickness of the blades 4. Cleanliness of the surface of the blades 5. Distance from the impeller to the “mating part” (“cover”) of the pump

The use of a sheet metal impeller with an additionally attached “belt” under the blades on LUZAR “TURBO” pumps ensures optimization of parameters 1, 3 and 4, and additional control of the impeller “overhang” ensures the implementation of parameter 5.

Will increased coolant consumption harm the engine?

Engines for VAZ 2108-2115 (8 class) and VAZ 2110-2112 (16 class) cars initially have a “hot” character - that is, they are prone to overheating. For example, the fluid flow rate at idle engine speed for a pump for a “Classic” is 900 l/h, while the flow rate for “front-wheel drive” pumps is only 400 l/h. At the same time, the VAZ 2111 and VAZ 2112 engines have more power.

In addition, improved fluid circulation has a beneficial effect on the temperature balance of the engine. Fears that “the cabin will be colder in winter” are groundless - the thermostat is responsible for the engine temperature.

Malfunctions

Water pump for car

The causes of failure can be different, for example, bearing jamming or the formation of play. Sometimes it happens that the impeller begins to spin freely, but separately from the shaft. The pump also needs to be replaced if it leaks or becomes noisy.

Life time. A lot depends on the quality of the pump. For example, a low-quality and defective pump can last only 10-15 thousand km. The service life of a high-quality part is when the Priora runs 100 thousand km. and more.

The manufacturer installs a pump on the Priora, produced by the Russian enterprise Togliatti Automotive Units Plant (TZA). It has a long service life.

Unfortunately, recently sales of counterfeit pumps from TZA have become more frequent. Is it possible to distinguish a fake so that your Priora does not suffer?

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.

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 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.

What to do if they are already bent?

When this rumored incident has already happened, you need to know that dismantling these parts, as well as replacing hydraulic compensators (Priora, 16 valves), is not such an easy process, because it requires disassembling the cylinder head. It should be noted that disassembling the cylinder head itself is done only in particularly difficult situations. That is, only when replacing springs, valves

and other fundamental devices. Also, every time the cylinder block is disassembled, a new gasket is installed.

Replacing the Priora pump 16 valves with your own hands.

The replacement of valves on a Priora (16 valves) begins with disassembling the engine. It is not necessary to disassemble the entire motor - it is quite easy to remove the head and install it on a special workbench so that the distribution heads are placed at the top. Next, you need to remove the left side motor mount. For this purpose, unscrew the nuts holding the support. Once they are unscrewed, removing it will be very simple. Next, you should dismantle the support bracket, having previously removed the bolts securing the fuel pipe and phase sensor. Next, if you have a key for 21, disconnect the sensor from the emergency one that allows you to conduct accounting (software). This element indicates a critical oil level; it is located in the bearing housing.

Signs of a pump malfunction

Thanks to the rotation of the pump driven by the timing belt, the impeller circulates a special fluid (antifreeze, antifreeze) through the small and large circuits of the cooling system. A damaged pump can cause the engine to overheat or cause the timing belt to break. To avoid an emergency on the road, you should do preventive repairs on time. On a VAZ 2110 with an 8-valve engine, the omen of replacing the pump can be recognized by the symptoms described below.

Noise from the timing belt cover

When the engine is running, a shuffling rotating sound is produced from the side of the timing belt protective cover. This is an indication that the pump bearings are sufficiently worn. According to the maintenance regulations, the pump should be changed every second timing belt replacement. The recommendation should not be neglected, since the rolling shaft bearings operate under load and wear out relatively quickly. Sometimes antifreeze or antifreeze gets into the bearing race due to a leaky seal. As a result, the lubricant is washed out and wear of rubbing parts accelerates.

Coolant leak from under the pump

Hermetic seals: the oil seal and rubber cuffs, as well as the bearings, have a limited service life. Typically, seals leak after bearings wear out, as there is play in the shaft. In addition to this, the constant cycle of heating and cooling of the engine gradually destroys the material of rubber products. As a result, small puddles of coolant appear under the engine compartment of the VAZ 2110 on the pump side.

Misalignment of drive shaft pulleys

A defective pump can result in noisy engine operation and frequent timing belt breaks. According to the performance characteristics, skewed rotation of the pulleys does not provide the vehicle with a long service life. The belt cannot withstand additional loads and breaks after a mileage of up to 1000 km. As a result, you will have to replace the defective pump, otherwise on such a VAZ 2110, an unscheduled replacement of the timing belt will become a regular procedure.

Motor overheating

The pump impeller may be partially destroyed. The lack of blades leads to a decrease in coolant circulation. As a result, the engine does not receive proper cooling from the small circuit and the temperature rises, even to the point of boiling. Overheating, in turn, has a detrimental effect on the engine.

Among the most common consequences, the most difficult to eliminate should be listed:

• can “drive” the cylinder head;
• the cylinder head gasket burns out;
• piston rings are destroyed;
• the motor risks jamming;
• The crankshaft bearings fail.

For reference! Frequent use of a special sealant to eliminate coolant leaks reduces the service life of the water pump. The foreign mixture tends to stick to the impeller, forming a solid clot and clogging the channels of the cooling jacket.

How is the pump replaced on a Priora?

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.

You need to rely on reviews, contact trusted stores or order the part directly from the manufacturer via the Internet in order to buy a pump for a Priora or another domestic car of good quality and avoid a collision with a fake. A survey of VAZ 2110 car owners on the question: “Which pump is the best for the VAZ 2110?” - shows that car owners mainly buy water pumps from 2 manufacturers: Tolyatti Automotive Unit Plant and Luzar.

Replacing the pump on an 8-valve VAZ-2110, 2111, 2112

The pump (coolant pump) is one of the main elements of the cooling system of an internal combustion engine.
It serves to pump coolant into the system, thereby ensuring its circulation and cooling of the entire engine. The pump structure consists of a housing, an impeller, a bearing and a drive gear. In VAZ 2110 cars (8 valves), the pump is located on the right side of the engine cylinder block (in the direction of travel) under the timing belt cover.

It is driven directly by the timing belt, which, while moving, rotates the drive gear.

What's next?

In this case, the replacement of valves on the Priora (16 valves) is not completed. When you unscrew the spark plugs, you should unscrew the bolts securing the camshaft, which remains for our client to do, and then remove this part from the outside. There are two of them on the sixteen-valve Priora, and both shafts must be removed. For this purpose, you will also need to remove the plugs located at the end of the cylinder head. When the engine is disassembled, the valves are specifically replaced. On the Priora (16 valves) it is done like this.

After removing the camshaft, use a puller to remove the fastening “crackers”. In this case, it is recommended to place a small stand under the “plates”. How to replace the valves on the Priora (16 valves)? After removing these parts, the plate is removed along with the springs. You have to be very careful because the spring force is very huge. Due to carelessness, they sometimes jump off the plate. There is still one piece under the springs. These are stubborn plates. They also need to be removed. Alas, this is done only after removing the valve seals. In order to dismantle it, we will use a special grip.

The dismantling process is as follows. We clamp the oil seal with a grip and at the same time press it a little. After making a couple of turns left and right (at the moment of turning), we pull the oil seal upward. It is not recommended to make such tilts with a pressed grip, because there is a risk of damaging the seating shoulder of the mechanism on the guide sleeve. We have done most of the work. Now all that remains is to remove the old valves and install new ones.

What kind of pump is installed on Priora

The original pump TZA 21126-1307010-75 . 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.

Pumps for 16 cl motor

• LUZAR LWP 0127
• FENOX HB1005P1
• HOFER HF033024
• LADA IMAGE 21126130701082
• 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 advise you to purchase a high-quality analogue or an original pump, so that you do not have to change it again after 20-30 thousand kilometers.

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 counterfeit parts these days.

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 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.

At the slightest sign of pump malfunction, it is recommended to inspect and replace it. Otherwise, the car's cooling system will be disrupted and engine overheating will be inevitable. And its repair will require more serious financial investments.

Thermostat

Next you need to go to the thermostat. " Priora " (16 valves), in which replacement of the thermostat itself is not necessary, 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. After which we need to extract what remains to be done for our client to make candles. With all this, such an act as replacing a pump

, " Priora " (16 valves

) will not seek from you. Below you will find a detailed description of how to dismantle the candles.

Instructions for replacing the pump on a 16 cl engine yourself

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.

For more detailed instructions, watch the video:

Survey of portal users

Pump wedge, resulting in timing belt break

Inspection of the pump must be carried out regularly, since the entire circulation of coolant in the system depends on its condition. It is brought into working condition mechanically, that is, with the help of a timing belt, which is also connected to the generator. Accordingly, if it breaks down, the movement of the coolant stops and the antifreeze begins to boil in the tank. Not only does the car engine overheat very quickly, but problems may also occur with the transmission of voltage to the system.

Checking the functionality of the water pump on the VAZ-2114

If you have doubts about the fact that the pump is faulty, and an external inspection for the presence of coolant leaks did not produce any results, you can do the following:

• Place your hand on the upper hose of the radiator while the vehicle is running.
• Next, squeeze it with a little force and try to feel the pulsation of the movement of the liquid.
• If this is the case, it means that the fluid is circulating and does not need to be replaced.

If during such a test you still do not feel anything and one of the signs described below is present, then this will be the most important reason to check and replace the pump.

Important points

• When reassembling the cooling system, pay special attention to the mark on the crankshaft pulley and the triangular slot located on the oil pump cover. These marks must be combined, since this is the only way the piston of the first cylinder is guaranteed to be installed at top dead center. If the mark on the pulley is difficult to see, you can apply a drop of red or white paint to it.

The mark on the pulley, made with red paint, will be better visible when replacing

• Also, do not forget about the tension of the timing belt. You need to take the above-mentioned retaining ring puller, install it in the outer groove of the timing belt tension roller disk and turn it to the left. There is a cutout on this disk that must align with the rectangular protrusion located on the inner bushing of the tension roller. As soon as the marks are aligned, use a 15mm torque wrench to tighten the fastening bolt (and the tightening force should not be higher than that specified in the vehicle’s operating instructions).

Repair of pump VAZ 2110/11/12

If the failed water pump is relatively new and its service life has not yet expired, you can try to repair it. This will require special tools, new parts, seals, etc.

To repair a faulty pump, you will need to purchase the necessary parts.

Disassembling the pump

The pump is disassembled in the following sequence:

1. The removed pump is wiped with a dry cloth.
2. Using a special puller, the pulley is removed.
3. The bearings are knocked off the shaft with a hammer.
4. The shaft is removed from the pump housing.
5. The impeller is removed.
6. The oil seal or what is left of it is removed.
7. The insides are thoroughly washed and cleaned.

If the pump is leaking, the seal must be replaced. The cause of a whistle at high speeds is usually a strong shaft wear.

Video: disassembling the pump

Replacing the oil seal

The oil seal is a rubber seal consisting of a metal rim, a spring and rubber. In any case, when disassembling the pump, the oil seal should be replaced, since the rubber wears out quickly. The procedure for replacing the oil seal is as follows:

1. The old seal is removed from the shaft.
2. The seat is cleaned of dirt.
3. A new seal is installed.

Pump leaks are usually caused by worn out seal.

Replacement of shaft and bearings

Often, due to high production, bearings have to be replaced. They can only be knocked out using special tools (a puller or a hydraulic vice). Therefore, a new shaft with bearings already mounted on it is usually installed in the pump.

The pump shaft is replaced along with the bearings

Replacing the pump pipe

Changes in pressure in the cooling system often lead to deformation of the coolant inlet and outlet hoses. These hoses are replaced as follows:

1. Use a screwdriver to loosen the clamp on the pump side.
2. The fastener is removed along with the hose.
3. The clamp is loosened and removed from the other side.
4. The pipe is removed and pulled out from under the hood.

Pump lubrication

Periodically replacing the water pump lubricant will significantly increase its service life. Some pump designs have special holes for lubrication. If there is no such hole, the water pump will need to be disassembled.

Some water pumps have special holes for lubrication.

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 2021, the brand’s 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.

• minimum cost;
• well-known company;
• good efficiency.

• 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.

• minimum number of defective parts;
• high-quality impeller design;
• sufficient performance;
• moderate price tag;
• long service life;
• presence of a rubber gasket included.

• The assortment does not have a price list for some popular cars.

According to motorists, the best VAZ 2107 pump is produced under the name of this brand.
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.

• wide use;
• large selection of modifications;
• good protection against counterfeiting;
• long service life.

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.

Twisting force

During the upcoming assembly, pay great attention to the force with which you twist them back. For a car like the VAZ Priora, the torque is 30-40 Nm. If you don’t have a torque wrench, use the traditional method. For this purpose, we twist the candle with one hand according to the full program. These efforts are completely enough to screw the parts into the well. When, if you lightly clamp the spark plug, during engine operation it can simply shoot out due to the enormous pressure in the combustion chamber of the engine.

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.

What should I do to prevent the valves from bending?

Often motorists solve this problem by installing a piston group of type 124. But this replacement does not require your own funds, reviews say. After all, for this purpose you will need to remove the old piston group, pull out the engine, disassemble it, remove the shafts, which remains for our client to do, etc. For 100 for such a function they will charge you about 50 thousand rubles.

The main reason that causes the need to replace the pump is the start of a leak in the cooling system. If the car owner discovers a leak, you can continue driving for some time, but it is better to limit it to driving to the nearest service station or to your own garage.

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.

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:

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.

Tools for work

To extract these elements, we need the following set of tools:

1. Spark plug wrench 16 mm with sealing rubber.
2. 10mm wrench with ratchet.
3. Ratchet handle.
4. Extension. Without him we won't get to the wells.

First, the upper motor casing (plastic decorative trim) is removed. When, before this, it is necessary to remove what remains for our client to do, the ignition coils. For this purpose, remove the plug from each side and unscrew the bolts securing each of them. Next we move on to the candles. For this purpose, you are recommended to use a spark plug head with a rubber ring to grip the part from the well. Here the extraction of candles is complete.
