Check of tightness of hoses and fluid leakage
Leaks in cooling system are usually found out on white or colors of a rust to a touch in the area adjoining leak. Carefully check the radiator and coolant hoses over the entire length. Replace hoses with cracks, ruptures and aging signs. Cracks are easier to detect if to press a hose. Pay special attention on collars which attach hoses to elements of the cooling system. Hose clamps, which have been strongly tightened, can cause rupture or a hose puncture, which will result in a cooling system leak. Inspect all hoses and the surface of the hose connections for leaks. If you found any problems of similar character with leaks replace this component or a lining. Fuel leaks precisely to define difficultly while leak does not become essential and, hence, easily visible. Fuel tends to quickly evaporate as soon as it comes into contact with air, especially in the hot engine compartment. Small drops can disappear before you can define a leak place. If you suspect that there is a fuel leak in the engine compartment then cool the engine and run it until it is cold, at an open cowl. Metal subjects tend to be compressed in a cold condition, and rubber hoses tend to be weakened, so that any leaks will be more obvious, while the engine heats up from start and a cold state. If there are signs that there is a leak of any liquid, but you can not identify the type of fluid or the exact origin, it is necessary to leave the car for a long time and put a large piece of paper or a rag under the car. This will help to find a place liquid flow, as well as help to identify a following liquid on color. But keep in mind that some leaks can be shown only when the engine is running. Leak in a vacuum hose means that air is sucked into the hose (instead of leaves a hose), and it does leak very difficult for detection. The detection method is to use the old vacuum hose as a kind of a stethoscope. Hold one end of the hose close to the ear (but not in the ear), and the 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.
