Domestic cars are always in constant demand in Russia. On the one hand, these are affordable means of transportation, on the other hand, their ease of maintenance allows you to carry out repairs on your own. One of the most serious breakdowns of the Lada Kalina can be considered pump defects. Indeed, if the pump is out of order, you cannot operate the car - there is a high probability of the motor jamming. Therefore, Kalina owners should pay special attention to the performance of the pump and the engine cooling system as a whole.
Why do you need a pump in a car?
The pump (or water pump) on the Lada Kalina is a device that circulates coolant. The pump starts working together with the power unit, that is, after the moment of ignition, the pump also starts working.
The circulation of antifreeze/antifreeze in the system is ensured by the rotation of the pump shaft on which the impeller is located . The impeller blades create the necessary fluid pressure, due to which the motor is cooled uninterruptedly. However, if there are any defects in the pump, antifreeze stops being supplied to the cylinder blocks, so the engine can “boil” and fail. Therefore, for high-quality and timely cooling of the engine, it is necessary to monitor the condition of the pump.

Characteristics of the device, symptoms of failure
This is what the pump for Kalina looks like
The pump works together with the engine. It ensures uninterrupted operation of the fuel supply and cooling systems. The first carries out the transfer of fuel from the tank to the engine, the second - forced pumping of antifreeze or antifreeze.
The water pump-impeller, located on the shaft, is covered by a housing. The shaft has ball bearings at both ends and rotates due to torque by means of a belt attached to the engine.
Symptoms of a broken water pump:
- the red section of the tachometer indicates the overheating temperature of the car engine, this is confirmed by the readings of the device;
- in the cabin of the Kalina car there is a persistent smell from the evaporation of antifreeze;
- a sound similar to a whistle is heard quite clearly - repair or replacement of the pump is necessary;
- Drops of liquid may be found under the car (to identify the problem, leave a sheet of white paper under the car overnight).
To restore the functioning of the pump, experience and special tools are required. It is advisable to entrust the work to specialists at a service station, and replace the pump with a new one.
How to determine if the pump is faulty on Kalina
The first sign that the water pump on a car has started to work incorrectly can be considered extraneous noise in the engine compartment while driving.
Lada Kalina cars are equipped with water pumps with a strictly fixed service life - 60 thousand kilometers or 48 months of operation (whichever comes first). Therefore, when this period approaches, it is recommended to change the pump, even if there are no signs of malfunctions yet.
However, in some cases, the pump may fail earlier than stated. You can check the functionality of the water pump in the simplest way:
- Warm up the engine to the optimal temperature. After warming up, use a gloved hand to pinch the upper pipe that comes from the radiator.
- If the pump is working properly, you will immediately feel the fluid pressure in the nozzle. Accordingly, the pump works as coolant circulates through the system.
- If pressure is felt, but weak, or not at all, it will be necessary to proceed to a detailed inspection of the pump.
- You will have to remove the timing case and visually assess the external condition of the pump.
- If there is a leak of antifreeze at the landing site, it means that the oil seal (seal) has failed.
- If a roar is heard while driving, we can conclude that the pump shaft bearing has worn out. You can pump the drive part of the pump gear by hand. If there is play, the pump will not work correctly.
Loss of pump tightness leads to disruption of fluid circulation in the system
Thus, it is possible to identify pump malfunctions without removing it from the car. The procedure is quite simple and accessible even to a novice driver.
Pump Lubrication Procedure
When drivers talk about lubricating the pump, they mean lubricating the water pump bearings. There are two bearings installed on the shaft, which require a small amount of lubricant to operate correctly. Experienced drivers lubricate the pump without removing it from the car:
- Remove the gas distribution casing.
- Clean the pump mounting area and the pump housing itself from deposits, dust and dirt.
- Apply Litol-24 or VNIINP-207 with your finger to the joints of the housing.
A better lubrication procedure will be carried out during pump repairs, when faulty parts are replaced. However, this procedure can also ensure a normal amount of lubricant in the bearings:
In principle, it is possible, but it is not convenient to remove the oil seal. Remove the oil seal and lubricate the cage with warm lithol, it covers the balls there but there are slots in it, so it will still get on the balls, although there may be lubricant there

Standard part - article number, price
AvtoVAZ installed parts with the catalog name “Pump. Water pump" for Lada Priora 16 valves and number 2109-01307013-00. Price: about 2,000 rubles.
Operating principle of the device
The pump design is quite simple. It consists of the following parts:
- Frame;
- Bearing;
- Impeller;
- Stuffing box;
- Shaft;
- Cardboard spacer;
- Drive pulley hub;
- Pulley.
The timing belt smoothly rests on the device pulley, which clings to the teeth. When the engine starts, the camshaft starts moving, and then the belt begins to move. The pulley turns slowly, causing the shaft to move. The shaft, unwinding, transmits torsion to the impeller through a series of bearings and seals.
The impeller is installed between two tubes: the input flow comes from the radiator, and the output goes into the cooling jacket.
The part itself is a flat circle with applied arc-shaped “petals” that take up the liquid and throw it towards the cooling jacket. So, turning over and over again, they accelerate the flow of antifreeze inside the circuit.
Replacing the pump on a Lada Kalina (8 valves)
On an 8-valve Kalina, you can change the water pump yourself. However, if the car owner does not have minimal experience in car maintenance, many questions may arise. For example, which pump to buy, how to choose the right tool, and is it worth draining the antifreeze from the system completely?
Which pump to choose
When the time comes to change the water pump, car owners begin to look at car dealerships for a worthy replacement. But which pump to choose so that it lasts as long as possible and does not cause problems for the owner?
It is important to choose original factory products. This is immediately evident from the packaging - an uncreased box, a warranty card, the date of manufacture and service life are indicated. Original pumps are necessarily packaged in protective film and have holographic stickers.
In contrast, it will not last long - after 10 thousand kilometers the pump will need to be changed again.
At AVTOVAZ, designers install a TZA water pump on the Kalina. It has a long service life; drivers often change the pump only after 100 thousand kilometers. As an alternative, you can install more expensive German-made Bosch pumps - they are also famous for their quality and durability.
Where is the water pump located on Kalina?
Due to the fact that the pump is driven by the timing belt, it is part of the gas distribution mechanism. That is, you need to look for the water pump on the Lada Kalina from the side of the engine itself. Visually, before removing the belt, you can only see the pump pulley, which is involved in the gas distribution system.
The pump on the VAZ is located in the timing device
Preparing tools
It is recommended to prepare a standard set of tools for removing bolts and unscrewing nuts. You will also need a 6-point hex key. To drain the antifreeze without contamination and inconvenience, it is better to immediately find a container for draining and a rag to blot up any drops that have fallen on the engine elements. To ensure reliable installation of the pump, you can use a sealant with good thermal conductivity properties.
How much coolant to drain/fill when replacing the pump
In any case, before dismantling the old pump, you will need to drain the antifreeze from the system. This is necessary in order to reduce the pressure in the hoses and not be injured during sudden releases of liquid.
If the water pump has not been changed for a long time, then it is advisable to immediately drain the entire volume of antifreeze from the system and replace it with a new one. If the car owner has recently filled in new coolant, then there is no point in completely draining it: just disconnect the hoses from the expansion tank and wait until the antifreeze comes out.
To make it easier to fill a large volume of coolant, drivers usually use funnels
Operating procedure
First of all, you will need to install the machine on a flat surface. You can drive the Kalina into the inspection hole, you can simply lift the front right part on a jack. It is recommended to make sure that the car is securely secured; it is better to place additional supports under the body beam.
When dismantling the pump, you will need to remove the timing belts.
The work of replacing the pump on the Lada Kalina is carried out according to the following instructions:
- Remove the engine splash guard.
- Disconnect the negative terminal from the battery.
- Unscrew the cap from the expansion tank and immediately remove the plug located on the cylinder block. Wait until the coolant drains out.
- If all the antifreeze is drained, then unscrew the cap from the radiator and place a container under the drainage area.
- After the antifreeze has been drained, screw all the plugs back on.
- Remove the protective cover from the timing belt.
- Loosen the belt by slightly tightening the timing pulley.
- Remove the drive belt.
- Remove the four bolts that secure the pump pulley to the cylinder block.
- After removing the pulley, unscrew the last screws securing the pump.
- Pull the water pump out of its socket along with the gasket.
- Clean the planting site from adhering dirt and antifreeze drips.
- Apply heat-resistant sealant to the edges of the hole and install a new gasket on it.
- Place a new pump on the gasket and then proceed in the reverse order of removal.
Video: how to replace the pump yourself
When working with timing rollers and pulleys, it is recommended to immediately fix the working position, since the installation process can be very drawn out due to the length of time it takes to set all the marks.
What you need for work
To replace the pump on your VAZ-2109, you need to prepare some tools and materials. In particular, you will need:
- heads and wrenches (socket and socket) 17 mm and 10;
- knob;
- wide flat-tip screwdriver;
- sharp knife;
- wiping ends;
- capacity up to 10 liters for liquid;
- silicone neutral sealant;
- jack and additional support for the car;
- new pump with gasket.
Replacing the VAZ-2109 carburetor pump should be carried out on a level surface. In summer it is not forbidden to work outdoors, but in winter it is better to use a warm garage.
How to connect an additional pump on the Lada Kalina
Most modern cars have two water pumps installed at once. This ensures the highest quality engine cooling in any operating conditions. You can also install a second (additional) pump on the Lada Kalina, and this work takes a little time and effort. The most difficult thing is to get to the place where the pump is fixed, since you will have to disassemble many engine compartment parts.
An additional pump is needed not only for high-quality engine cooling. Mostly, Russian car owners install a second pump to improve the operation of the heater in the cabin during the winter - the car warms up faster.
In order to install the second pump on the Kalina, you will need:
- new pump;
- hoses of different lengths;
- fasteners (depending on where exactly it will be easier and more convenient to screw the pump);
- sealant.
The essence of the work is to organize a small circle of coolant circulation throughout the system.
Doing the work yourself
The first step is to assemble the assembly itself from the materials that are at hand. The pump is connected to two hoses (the short one will provide fluid removal, and the long one will provide supply). The hoses are attached to the two ends of the pump with clamps. Then follow the following procedure:
- The coolant will need to be drained. You can simply empty the expansion tank without draining the entire volume of antifreeze.
- Near the bottom of the car, find two hoses (one leads the antifreeze to the stove, and the other takes it away from it). Disconnect the outlet hose and instead attach the assembled structure with an additional pump.
- After this, attach the pump to the gearbox housing. Depending on the availability of fasteners, you can place the device on brackets or secure the pump with metal clamps.
In this case, the hoses are connected with clamps, and the pump itself is mounted on a metal bracket
At the end of the work, you will need to plug all hoses and plugs and fill in new antifreeze.

Thus, on Lada Kalina cars, the owner can independently change the water pump without resorting to the help of service station specialists. This will save money and also allow you to independently control the operation of the pump, taking into account the knowledge about the state of the machine system that was obtained during operation.

conclusions
In order to verify for yourself that the old pump is worn out and how it differs from the new one, simply take the old and new element and rotate the impeller on them in turn.
Comparison of the operation of the old and new pump. Check for play and ease of rotation.
You can clearly see from your example that on the old element its rotation will occur with interference, while on the new element it will not be necessary to exert excessive effort.
