3.1.3.1.3. Check of tightness of hoses and вытекания liquids

PERFORMANCE ORDER

1. Leaks in cooling system are usually found out on white or colours of a rust to a touch in the area adjoining leak. 2. Carefully check up a radiator and hoses of a cooling liquid on all length. Replace hoses with cracks, ruptures and ageing signs. Cracks are easier for finding out if to press a hose. Will pay special attention on collars which attach hoses to elements of system of cooling. Collars of fastening of a hose which have been strongly tightened, can cause rupture or a hose puncture, leaks in cooling system will be result of that. Examine all hoses and surfaces of connection of hoses about leaks. If any problems of similar character with leaks replace this component or a lining are found out. 3. Fuel leaks precisely to define difficultly while leak does not become essential and, hence, 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 leak of fuel in the field of a motor compartment then cool the engine takes place and start it, while it cold, at an open cowl. Metal subjects tend to be compressed in a cold condition, rubber hoses tend to be weakened, so any leaks will be more obvious, while the engine heats up from start and a cold condition. 4. If there are signs that there is a leak of any liquid, but you cannot distinguish type of a liquid or an exact origin it is necessary to leave the car for long time and to put the big piece of a paper or a rag under the car. It will help to find a place of course of a liquid, and also will help to identify a following liquid on colour. But keep in mind that some leaks can be shown only at the working engine. 5. 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 detection method consists in using an old vacuum hose as some kind of a 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 hose end will be directly 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.
