With the onset of the warm season, engine cooling system is experiencing an increasingly serious burden.  It is recommended to examine all components of the system. At the initial level of the owner himself in a position to conduct such inspection in the time it take to check the oil level.

How to bleed a radiator?

Begin to repair the radiator is to check the coolant level, which is in the expansion tank. This reservoir is located on the driver side to the left of the engine compartment near the battery. It is marked min / max. In the event that is difficult to determine the level of fluid due to contamination of the tank, you can simply pick up higher. He keeps on vertical guides, which allow removing it without difficulty.

Evaluation max is the limit for the fluid level in expansion tank when the engine heats up to optimum temperature for operation. If the antifreeze level is too low, fluid should be topped up. In cases where the fluid reservoir is not making refilling, you should check the level again. When the engine is cold to open at the neck of a radiator cover to determine how much antifreeze in it. Then, if necessary, it should pour directly into the radiator.

Typically, one liter of fluid topped once in 6-9 months.
The second step in verifying - examination of the upper radiator pipe, which is slightly curved rubber pipe, about 30 cm long. When the engine is warm, fitting over the entire length should have the same diameter and be sufficiently rigid in compression. Should not be allowed blistering. Since the top tube is exposed to high temperatures, it cannot be touched without protective gloves. If, having checked a few times, you make sure that pipe is in compression soft all the time, this suggests that the safety valve cooling system, both as filler cap to be defective. This element also requires regular inspection. Fluid must penetrate unhindered into the radiator through the valve. In this case, the valve must pass it back only. When the pressure reaches a certain value.

During the audit, a special tool. Among the failures is most common valve destruction, as well as swelling of rubber seals.

However, the first thing to do at the beginning of the inspection - is to check the top of the radiator. Damage to the cooling system is often just the appearance of a radiator leak at this location.

Flow is formed because of cracks in the part of the radiator, which is made of plastic, near the site of attachment of the diffuser and the bracket that supports the accelerator cable. A small first crack grows until out of it begins to evaporate the liquid, and then select the color pigment of antifreeze. Then, the radiator starts to get wet, and the liquid pours out.
