Check of a condition and replacement of hoses of an impellent compartment
The general information
Fuel hoses
8 Fuel hoses usually are under pressure, therefore at their detachment be ready to that fuel will be sprayed also it it is necessary to collect.
9 Check up all rubber fuel hoses on presence of signs of deterioration and attritions. Pay special attention on sites of a bend and in front of unions, for example a junction of a hose with the fuel pump or the filter, cracks there can be formed. 10 Use only high-quality fuel hoses. Never, under no circumstances do not use as fuel not reinforced vacuum hoses, transparent plastic tubes or water hoses. 11 For fastening of fuel hoses collars of tape type are usually used. These collars weaken in due course a tension and can "jump out" at removal. At replacement of hoses replace such collars with collars of screw type. Metal lines 12 Between the fuel pump and system of injection of fuel sections of metal tubes are often inserted. Carefully check these tubes on presence of dents, twisting or cracks. 13 If it is necessary to replace section of a metal line, use only seamless steel tubes, since copper and aluminium tubes are insufficiently strong to resist to the vibrations caused by work of the engine. 14 Check metal brake lines in places of their connection with the main cylinder and with a regulator of pressure or ABS (if it is available) on presence of cracks or weakened штуцерных connections. Any signs of leak of a brake liquid demand immediate careful survey of all brake system. Hoses of system of hydrostrengthening of a wheel 15 Check up hoses of system of hydrostrengthening of a wheel on presence of signs of leak of the liquid, weakened штуцерных connections and the worn out collars. It is necessary to replace proceeding hoses and the worn out collars. Hoses of system of cooling Leaks in cooling system are usually found out on white or colours of a rust to a touch in the area adjoining leak.
Detection of places of leaks 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 impellent compartment. Small drops can disappear before you can define a leak place. If you suspect that leak of fuel in the field of an impellent compartment then cool the engine takes place and start it, while it cold, at an open cowl. Metal subjects are compressed at cooling, and rubber hoses tend to be weakened, so any leaks will be more obvious, while the engine heats up at start from a cold condition. 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 liquid on colour. 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 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. |
