GENERAL INFORMATION

Leaks in system of cooling are usually found on white or colors of a rust to a raid in the area adjoining leak.

Precisely it is difficultly to define leakages of fuel, while leak does not become essential and, therefore, easily visible. Fuel tends to evaporate quickly as soon as it contacts with air, especially in a hot motor compartment. Small drops can disappear before you can define a leak place. If you suspect that leakage of fuel in the field of a motor compartment takes place, then cool the engine and start it, while it cold, at an open cowl. Metal subjects tend to be compressed in a cold condition, and rubber hoses tend to be weakened, so any leaks will be more obvious, while the engine heats up from start and a cold condition.

If there are signs that there is a leakage of any liquid, but you cannot distinguish type of liquid or an exact origin, it is necessary to leave the car for long time and to put a big piece of paper or a rag under the car. It will help to find a place of course of liquid, and also will help to identify followed liquid on color. But keep in mind that some leaks can be shown only at the working engine.

Leak in a vacuum hose means that air is sucked in in a hose (instead of leaves a hose), and it does leak very difficult for detection. The method of detection consists in using an old vacuum hose as some kind of stethoscope. Hold one end of a hose close to an ear (but not in an ear), and other end use to investigate area round prospective leak. When the end of a hose will directly be over the leak place, the hissing sound will be clearly audible through a hose. It is necessary to avoid contact to hot and moving details as the engine at check should work.
