Replacing the pump VAZ-2114 "Samara-2" with their own hands

The pump is one of the most crucial elements of the SOD engine of each car. If the pump fails, the motor will often overheat, which can lead to the most unpredictable consequences. The domestic car VAZ-2114 is not the exception. How to change the pump with your own hands on "Samara" and what this element represents - later in this article.

A few words about the pump device

The design of the pump is very primitive at first glance. The water pump consists of only a few elements - the body and impeller, which is placed on a shaft with a pulley. The body of the element is made of aluminum or steel. There are special channels in it that are retracted and bring the antifreeze to the impeller. There is a small gasket between the cylinder block of the engine and the pump body. The latter performs sealing functions, preventing the risk of leakage of the antifreeze from the pump to the outside. The impeller, or "impeller", is the most important element in the design of the pump. Its function is to circulate the liquid in the SOD system. This part is mounted on the drive shaft. The latter is placed on the bearings inside the pump body. The drive pulley is attached from the opposite side of this shaft.

How to check the serviceability of the pump?

In total, there are several methods for checking the pump for operability. The simplest way is given below. The essence of it is that we need to warm the VAZ engine to operating temperature (+ 82-90 degrees Celsius). After that, it is necessary to squeeze the upper branch pipe of the radiator. If the pump is working, you will feel the throbbing in the branch pipe.

Also check the oil seal and see if the liquid is flowing through it through the pump holes. To do this, remove the timing belt cover , then visually determine if the antifreeze flows through the holes described above. If they have characteristic deposits (often they have a brown color), the stuffing box has come into malfunction and it should be replaced.

If the bearing of the pump shaft fails, this will be signaled by a lingering sound in the front part of the engine compartment.

To make sure whether the pump is needed, the VAZ-2114 is subjected to detailed diagnostics. It is required in cases where the failure of a water pump by eye is simply impossible to determine. In this case, the pump is pulled out. Particular attention during inspection should be given to the reverse side of the rotor. Most often, its blades are destroyed by rust.

How does the water pump of VAZ 2114 "Samara" change?

This procedure does not require special knowledge and skills, so absolutely any motorist can cope with it. It should be noted that before the pump is replaced, the VAZ-2114 and its engine must cool to the outside temperature. In other words, the water pump only changes when the engine is cooled down. So, what needs to be done? To begin, we de-energize the vehicle's on-board network by removing the negative terminal from the battery. Then merge the old antifreeze and remove the drive belts. After that, we disconnect the pump and pay attention to the blades. The latter should not contain cracks or other damage. How to replace the pump VAZ 2114th "Lada"? Next, remove the old sealant and put in its place a new one. As an alternative to the sealant, you can install a new O-ring. Then install a new pump. Further assembly is in the reverse order. This is the question of how to replace the pump VAZ 2114th "Lada", we can consider closed.

Verify installation

After we have installed a new pump in its place, we need to check its functionality. To do this, fill the expansion tank with a new antifreeze and start the engine. If the work was done qualitatively, there should be no leakage of coolant. By the way, all the above instructions are suitable not only for the 14th "Lada", but for its predecessors VAZ 2108 ... 099. They all have a similar design, so the process of diagnosing and replacing the water pump is absolutely no different.

Why should not we neglect the replacement?

Despite such a small size and primitive design, the pump plays far from the most recent role in the life of the car. If the element is not replaced in time, the engine will constantly be subjected to overheating. And this significantly reduces the resource of its operation and can lead to failure of the timing belt. Therefore, do not tighten with the replacement of this part in case of malfunctions.

Resource of work

On cars VAZ of the family "Samara" water pump serves an average of 3-3.5 years of operation. After this period, the pump can come to a fault at any time. Although its exact resource depends on the manufacturer itself - the better this part is made, the more it will serve.

Conclusion

So, we found out what a detail like the water pump (VAZ-2114) is. What better pump will work on "Lada", there is no definite answer. However, judging by the feedback, the best solution is to buy a LUZAR pump.
