What is the cylinder head gasket and why is it important for VAZ?

The operation of a domestic car has its advantages and disadvantages. The first can include cheap cost of spare parts, their availability in the Russian market, ease of maintenance. But on the other hand, these same details are characterized by their short life span. Therefore, replacing the cylinder head gasket (VAZ) is a common occupation for every motorist. And today we will talk about what this spare part is for and when it needs replacing.

What is it and what is it intended for?

The cylinder head gasket (cylinder head) serves to seal the place where the engine assembly is connected to the head. This spare part is interconnected immediately with three components: a gas distribution system, an oil cooler and a cooling system. Therefore, despite its cheapness, the cylinder head gasket should change in a timely manner and meet all modern quality requirements. Otherwise, one of 3 (and possibly several) systems will fail. It is also worth noting that the lining of the lid and the head of the unit are two different things, which, although they perform similar functions, are not the same.

When can I change?

The cylinder head gasket can lose its functions at any time, and each new part will not have the same service life, even if these parts are manufactured in the same factory. Therefore, it is simply not advisable to count the remaining kilometers on the instrument panel . In order to determine the current status of the cylinder head gasket, you need to know certain signs that indicate a malfunction or loss of functions of this part. So, let's consider the main factors by which it can be determined that this part has become unusable.

1. First of all, you will notice a leakage of coolant or engine oil in the place of attachment of the gasket.
2. White smoke. This sign indicates that the machine has malfunctions in the cooling system. Similarly, you can notice the presence of a white emulsion on the dipstick to check the oil. And in order to eliminate these problems, you just need to replace the gasket.
3. Oil stains of unknown origin appear on the expansion tank . They can get there only through a malfunction in the cooling system.
4. Bubbles appear in the same tank or in the radiator. They are due to a faulty cylinder head gasket.

Thanks to this knowledge, you will be able to determine the exact cause of the breakdown and correct the problem in time.

A useful tip for Russian motorists
