The head of the cylinder block is very important and inherently part of the motor in which many vital elements and mechanisms are focused. And even though the GBC device is quite complicated, there are several technological operations that every driver who has small knowledge and skills can be performed independently. This will give you a good opportunity to save the essential amount of your budget, which is very important for most car enthusiasts, especially in crisis times.

Engine cylinder, how to remove the cylinder and why to shoot it

As a rule, the replacement of the head of the cylinder block is necessary when the motor overheating is necessary and, most often, the driver himself is to blame. The engine overheating does not have to wear a pronounced character, for example, in the form of a pair from under the hood. However, it is even worse for the motor, because systematic overheating is able to lead to cracks between valve beds in steel liners or to the mass of other problems, as a result, requiring the replacement of the head of the cylinder block.

Another characteristic breakdown, which requires removing the head of the cylinder block - replacing the gasket of the GBC. In addition, if you need to check the head of the cylinder block for tightness, that is, to make a complete diagnosis, then before you provide the GBC to a hundred, it should be removed.

In principle, knowledge of the cylinder head removal technology is needed not only when troubleshooting. They will be needed, for example, when tuning a motor, and, accordingly, replacing the camshaft on the tuning camshaft.

For some processes, in particular, for pulling the cylinder head fastening bolts, the GBC is removed.

When removing the GBC, it is necessary to have a dynamometric key and the maintenance and repair manual specifically your model of the motor.

1. First you need to remove the battery and disconnect the ignition system wires.
2. Next, armed with a marker and begin to dismantle all pipelines and hoses that go to the motor - vacuum, cooling systems, and so on. When marking a marker, which goes out and enters, you will be much easier to collect all the details back.
3. Then dismantle the fuel lines and so on.
4. Now remove all the attachments mounted on the head of the cylinder block, which will interfere with its removal.
5. After that, it is necessary to remove the cylinder head cover.
6. Remove the belt of the gear pulley, not forgetting simultaneously to diagnose - inspect the camshaft gland and so on.
7. Next, we carefully remove the cylinder cylinder bolts. Look for the desired scheme in engine repair instructions.
8. Remove the GBC, after which we carry out planned repair work.

Gasket GBC, why need a gasket cylinder

The GBC gasket performs several actions at the same time - the channel cooling system channels compacts the engine oil system channels and compacts the cylinders of the gas distribution system of the motor.

As a result, the requirements for the element is quite high. It is worthwhile to know that the gasket is a one-time part and is subject to replacement for a new engine at each repair.

Gasket GBC, types of gaskets, dignity and disadvantages of each type

There are two groups of materials, of which gaskets of the cylinder head are made - metal and non-metallic.

The most common - metal gaskets CHC. Often they make them made of sheet copper or thin multi-layer sheet steel. Places that come into contact with the planes of elements are quite often covered with a rubber composition, to ensure a reliable seal. These gaskets are more wear-resistant and durable, in comparison with non-metallic gaskets. Pasters from copper can be found very rarely, as a result of the high cost of this material. It is important to know that even if there are no visible damage on the GBC laying, it is necessary to replace the gasket. This is a product of one-time application, which when tightening applies the shape of surfaces in contact with it. It is impossible to put the gasket of the GBC exactly at the same position. It is about this that when dismantling the head of the cylinder block should always buy a new gasket.

Non-metallic gaskets can be divided into blessing and asbestos. The latter produce from sheet asbestos. Usually for cylinders of these gaskets, the central holes are strengthened with steel rings that wear on the edge of the cuts. Holes for fasteners, which passes through the gasket, are equipped with the same rings. There are gaskets from the rubber mixture, which are pressed with the addition of graphite and asbestos fiber powder.

Gaskets made of blessing material are distinguished by increased wear resistance, but more expensive in production. They are made of rubber and synthetic fibers, which are pressed at high temperatures.

Replacing the GBC gasket when the GBC laying is required

Replacing this element may need anything, as it is not known how much it will last. There are a number of signs of exhaust gasket GBC:

1. The external leakage of the coolant or engine oil on the site of the block of block and the GBC.
2. On the probe when checking the oil, the white liquid is noticeable - the coolant falling as a result of the gasket worn.
3. The constant release of white smoke from the exhaust pipe is evidenced by either the overheating of the motor, or on the getting of coolant into the cylinder.
4. If, when checking the expansion tank or on the coating of the liquid in the radiator, there are oil stains, then, most likely, as a result of the failure of the gasket, the engine oil falls into the cooling system.
5. Exhaust gases fall into the cooling system, which is why the appearance of bubbles in the radiator or in the expansion tank is noticeable.

Replacing GBC gasket, step-by-step instructions

In fact, on all brands of vehicles, replacing the cylinder head gasket is the same. However, there are some features, in particular, the order of delaying and adjusting the protracted point of the cylinder bolts.

These indicators are listed in the operating manual of your vehicle. It is very important to clean the cylinder cylinder bolts in front of their spinning, which would not be formed a bolt slit defect. There are several more rules that need to be observed when replacing the gasket:

1. When purchasing this item, be sure to make sure that it is suitable for the power of the torque that the engine manufacturer describers.
2. To remove the tension, the promotion of the fastening bolts must be started at 0.5-15 turns from the middle.
3. After replacing the gasket, the GBC should be installed exactly on the guides.
4. We extremely gently unscrew and twist the bolts to distribute the voltage gradually on all bolts and do not thread threads.
5. Do not forget to consolidate all the details in the right way.

Tips of professionals

It is important to understand that the replacement of the cylinder head gasket is quite a complex operation that requires certain skills and special tools. Use only high-quality antifreeze and lubricants that are not aggressive to aluminum alloys. In addition, follow the state of the ignition system and use the fuel required brand.
