Replacing the pump on the Lada Grant. Recommendations from the selection specialist

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.

Instructions for changing the pump on Grant

Even before starting work, the car owner is recommended to read the machine’s operating manual; this will help you study the structure and location of the water pump in more detail. Remember - incorrect reassembly will lead to damage to the antifreeze in the system.

Then you need to prepare a place to work; normally this should be a dry box with a flat floor. Take care of good lighting, this will not only make the process easier, but will also insure you against the loss of small fasteners and small parts.

At the very beginning of work, the car is de-energized by removing the terminals from the battery. In addition, the car is securely secured using parking shoes or a hand brake. All these manipulations are carried out to ensure maximum safety and convenience of the work process.

When replacing, it is extremely important not to deviate from the sequence of actions given below, since violation of the described order of work can cause a breakdown of the cooling system and lead to a fire in the car.

Replacing the pump itself will require you to do the following:

• First you need to completely drain the coolant;
• Next, unscrew the fastening elements and dismantle the front cover of the timing case;
• Then fix the piston of the first cylinder at top dead center;
• The car is put into gear;
• A jack is used to lift the front wheel of a car;
• The wheel rotates until the mark on the pulley coincides with the mark located on the rear timing housing cover;
• Work is being done to dismantle the timing belt, the tensioner pulley is dismantled;
• The rear cover of the timing case is removed;
• The fastening elements securing the water pump are unscrewed;
• The element is carefully pryed off with a screwdriver, after which it is removed;
• In the future, you should install a new pump and previously dismantled elements and assemblies, performing actions similar to dismantling, but in the opposite order.
• Before installing a new pump, the mating surface of the cylinder block is cleaned of the remnants of the previous gasket and a new one is installed in its place, having first applied a thin layer of waterproof sealant to it. The drainage hole on the water pump body should be directed downwards after installation;
• The last stage of the work process involves pouring coolant into the cooling system.
• The liquid is filled to a level 25-30 mm below the maximum mark on the tank, this is approximately 8 liters of antifreeze. The work is done.

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

Replacing the pump

After checking the water pump, repairing it, or purchasing a new element, all that remains is to install it in place. We advise you to pay maximum attention to the moment of installing the gasket and tightening the fastening bolts. Some experts advise using sealants to provide reliable protection against leaks. Sometimes this is not possible because on some vehicles the sealant will prevent the pump from being loosened in the future to replace the timing belt.

In addition, follow the manufacturer's recommendations regarding bolt tightening torque (this information is in the service manual). Otherwise, you may pinch the gasket or damage the threaded connection. Finally, you need to fill in the coolant.

In the process of adding antifreeze or antifreeze to the cooling system, it is necessary to get rid of air pockets. After installing a new or restored pump and warming up the power unit, be sure to inspect the installation site for coolant leaks.

An important component of the Lada engine is the pump or water pump of the cooling system. This model features engines with the serial index VAZ-11183, VAZ-11186, VAZ-21126 (also with automatic transmission) and VAZ-21127.

This unit should be selected according to the part numbers

After all, the Grant pump is responsible for the safety of such an important engine part as the timing belt. Pump (water pump of the cooling system) Lada Granta catalog number – 21114-1307010-00, 21114-1307010-01

You can do a self-diagnosis of the pump malfunction yourself. This will only require a visual overview of the CO water pump department. When dismantling the pump, it will be easier to find the cause of the breakdown. Determination of malfunction Grant, pump:

• Makes noise, an unusual hum of bearings in the pump section. • Leaks in the pump area indicate the need to replace the gasket. • There may also be leaks in the drainage section of the pump - this is wear on the seal. • If the pump impeller wears out/breaks, there will be poor circulation of coolant in the system. • If axial play of the pump shaft is detected, the bearing is worn out.

The water pump ensures proper circulation of coolant in the car engine

Thus, infrequent monitoring, in which you should pay attention to the coolant pump section of the Lada Granta - the pump and the units associated with it, will serve you faithfully. And your car is no longer in danger of engine overheating due to a sudden malfunction

Do not forget that the performance of the stove also depends on the quality of the pump.

Unfortunately, counterfeit pumps are often found; be careful and always keep your purchase receipt or negotiate return conditions. Beware of fakes; after installation, carefully check the operation of the pump on a cold and warm engine.

The Lada Granta pump is represented by two reputable manufacturers. These are the companies TZA (Togliatti Plant of Units) and LUZAR (Lugansk Plant of Automobile Radiators)

Pay attention to the colors of the original pump. Compare grooves and ribs of the impeller

Compare all inscriptions on the pump with the original.

In auto markets you can find many water pumps for the Lada Granta. Choosing a good one without experience is not easy. Of course, it would be ideal to have the factory-made original with you for comparison. After all, the quality and prices at the bazaars are different, it is better to buy from official manufacturers; for comparison, the price of a pump on a grant is:

• TZA pump (21116-1307010-00) – from 815 to 1100 rubles. • LUZAR pump (21116-1307010-00) – average cost 1240 rubles. • Kraft – from 1550 rubles. • HEPU – from 1800 rubles. • In the markets you can also find supposedly “original” pumps for only 500 rubles. But it’s up to you to decide whether this untested part is worth purchasing.

Malfunctions and troubleshooting methods

Signs and causes of failure

You can identify a broken part by the following signs:

• insufficient circulation of coolant and, as a result, frequent overheating of the engine;
• hum of bearings at the pump mounting location;
• presence of smudges at the pump mounting location.

These markers indicate the most likely causes of malfunctions in the Grants pump:

• bearing wear or damage;
• damage to the seal;
• worn sealing gasket;
• broken pump impeller.

In most cases, the part becomes unsuitable for major repairs and requires a complete replacement. Ignoring pump problems leads to replacing the timing belt and replacing components of the connecting rod and piston group. Valves and bearings may also need to be replaced.

Price issue

Replacing the pump on a Grant will not significantly impact the car owner’s budget. The cost of a new part is in the range of 1000-2000 rubles. For a thousand you can order a “native” pump produced by AvtoVAZ. Closer to the upper price threshold are expensive foreign-made analogues with an increased resource. The average service life of a new pump is 150,000-170,000 kilometers.

Description and technical characteristics of water pumps DOLZ, LUZAR

The DOLZ pump is installed on Lada Granta cars with a modification of the VAZ 21116 engine. These are 8-valve units with a volume of 1.6 liters, a power of 87 horsepower, “Norma”, “Lux” equipment.

The manufacturer of the pump is Doltz, a Spanish concern that is famous for its high reliability and long service life of spare parts.

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.

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:

• wrench 10;
• socket head 10;
• wrench 17;
• a screwdriver with a flat and thin blade;
• sealant;
• container for draining coolant (at least 10 liters);
• rags.

Replacing the pump on a Lada Grant does not require special tools - a standard set of tools is enough

How much coolant should be drained and refilled when replacing

Regardless of the availability of time or desire of the driver, you will still have to drain the antifreeze when changing the water pump. This is necessary in order to relieve the existing pressure in the cooling system and protect yourself from possible risks. However, the main question is how much liquid needs to be drained.

Traditionally, when replacing a pump, the entire volume of antifreeze is drained, since the new water pump will need new coolant. However, if new antifreeze was recently filled in, then there is no point in replacing it. It is enough to drain 4–5 liters of liquid to reduce the pressure, and then pour the same liters back.

Antifreeze is completely drained in 10–15 minutes

Draining can be done in two ways:

1. Disconnect the pipes from the radiator and place a container under the drain holes. This method allows you to remove almost all liquid from the cooling system.
2. Unscrew the plug from the expansion tank housing - no more than 5 liters of antifreeze will leak out.

New coolant should be added only after all installation work has been completed. It is recommended to make sure that the antifreeze supply and discharge hoses are tightly connected to the fittings.

Pump replacement procedure

On an 8-valve Lada Granta, changing the water pump is somewhat easier than on a 16-valve one. All actions of the owner fit into the following scheme:

1. Drain the antifreeze.
2. Disconnect the wire from the negative terminal on the battery.
3. Place a jack under the front right wheel and remove it.
4. Next, unscrew the screws securing the timing case housing. Remove the casing.
5. Loosen the timing belt tensioner roller.
6. Reduce the tension on the alternator drive belt.
7. Remove the timing belt and the alternator belt.
8. Disconnect the inlet and outlet hoses from the pump. It is enough to loosen the degree of compression of the metal clamp with a screwdriver, and the pipes can be easily removed. Antifreeze may leak, so it is better to place a container under the pump fittings or place a rag in advance.
9. Remove the cover from the pump.
10. Unscrew the nuts securing the pump to the motor wall.
11. Pull out the pump.
12. Immediately after dismantling, you will need to clean the flange surfaces from leakage of antifreeze and dirt deposits, and be sure to remove any residue from the rubber gasket.

It is very easy to de-energize the car to safely replace the pump - just remove the negative wire from the battery terminal

It is best to remove drive belts after they have been loosened - this will make the procedure faster

Removing the water pump is done with bare hands - just pull the pump housing and it easily comes out of the socket

After this, you can install a new one in place of the old pump. All stages of work are performed in reverse order. Before installing the water pump, it is recommended to apply a thin layer of sealant to the gasket and wait 10 minutes until it dries a little. The sealant will create additional integrity of all pump elements and extend the life of the seal.

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.

Replacing parts on different types of engines

How to change a pump on a Grant with an 8-valve or a 16-valve, there is not much difference. The algorithm described above remains unchanged, taking into account one nuance: on the “eight” the crankshaft is equipped with one pulley, on the “sixteen-valve” - two. The replacement procedures will be identical, but when working with a 16-valve engine, the car enthusiast will need more time to complete the work.

It should be noted that when purchasing a pump, you need to pay attention to what type of engine the product is intended for. The packages are marked so that the car enthusiast can select the right part for an 8-valve and 16-valve engine, respectively.

Purpose and recommendations

The pump serves to ensure correct and sufficient circulation of fluid in the engine cooling circuit of the Lada Granta, which has 8 valves. The element requires periodic attention, which will allow the system to operate for a long time without sudden and unpleasant surprises. Neglecting the control action may lead to a sudden breakdown, and this will inevitably lead to overheating of the motor.

A high-quality product has a positive effect on the performance of the heating system of the Lada Granta version of 8 valves. The presence of counterfeits is very common, so you should be on the safe side in advance and discuss with the seller the details of returning substandard goods.

Which pump to choose? For the Lada Granta model, we recommend choosing an 8-valve pump between two manufacturers that have earned trust among car owners, namely:

• "TZA" (Tolyatti Plant of Units);
• "LUZAR" (Lugansk Automobile Radiator Plant).

An important aspect of the choice is to focus on the color scheme present on the cases of the original products. It would also be useful to compare the grooves and stiffeners made on the impeller. We recommend that you carefully check the entire list of markings and inscriptions with those on the original products.

Today, the market space is able to offer an impressive range of these products for the Lada Granta, which has 8 valves. A guaranteed option to avoid a collision with a fake is to take the original pump with you. Lack of experience in “communication” with spare parts of this kind can play a cruel joke on the buyer.

Which pump should you choose? You can purchase a pump from an official dealer, and if this option is not available, below we provide guidelines for the following analogues with a price parameter:

• "TZA" (code 21116-1307010-00) at a price of 815-1100 rubles;
• “LUZAR” (number 21116-1307010-00), around 1240 rubles;
• “Kraft” with a price of about 1550 rubles;
• “HEPU”, the most expensive version (1800 rubles).

There is an opinion that you can find an “original” on the market at a dubious price, from 500 rubles. However, it is not possible to guarantee the authenticity of the product, so here only the buyer is responsible for weighing this step.
