Leakage in the cooling system

Leaks in the cooling system may be indicated by the reduced level of the liquid in the reservoir tank and by runs of antifreeze.

The leakage of the cooling system may be caused by small cracks, gapping of pipe line or flanged joints. All the above reasons may be eliminated due to special products which are to be introduced into the cooling liquid. Polymers contained in such products help to fasten in the sources of leakage thus stopping it.

It is worth to be noted that if the engine is warm, it is under high pressure. It is important to be really careful while opening a radiator cap as hot steam or liquid may erupt.
