The cooling system is an important component of auto service. In order to avoid the engine breakdown from overheating, it is necessary to identify and solve problems with the radiator. And the first thing that is worth paying attention is to check the radiator cover.
1
First you need to carefully inspect the appearance of the lid to identify mechanical damage. Scratches, rust, cracks, corrosion and other signs of wear speak about the need to replace the lid to the new one.

The radiator cover serves as a barrier that holds the coolant. To hold a strong pressure, the design of the cover involves the spring. The next step will be the springs check. You need to try, with what force it is compressed. If the spring is compressed easily, it is not recommended to use such a lid.

Next, check the vacuum valve. It needs to be pulled and open. Then let go and see it completely closed. You also need to check the seat of the vacuum valve for the presence of a dirt that can prevent him from performing its function correctly. If there are deviations from the standard, then it is necessary to change the radiator lid.

Then, using a special instrument, the radiator cover reset pressure is checked. Take a pump and scril it to the lid, observing the instructions. When the pump is activated, wait when the valve opens. Pressure should be increased to the moment until the appliance arrow stops. Check the results with the following: the pressure for opening the inlet valve should be equal to 107.8 ± 14.8 kPa, and for closure - 83.4 kPa. When the average values \u200b\u200bare not satisfied with these, the cover must be changed.
It is recommended to come to insperse the radiator cover. And if it already needed a replacement, then you should also choose a purchase too. Focus best on the labeling of the old cover.
