Check of a state and replacement of hoses of a motive compartment
General information Influence of high temperatures in a motive compartment leads to gradual failure of the rubber and plastic hoses used in various systems. It is regularly necessary to make check of hoses on existence of cracks, weakening of fastening of collars, hardening of materials and signs of leaks. Information relating to cooling system hoses is provided in the Section Check of Functioning of the Cooling System, and to hoses of the brake system - in the Section Check of the Brake System. The majority of hoses (but not all) fasten by means of collars. Where collars are used, check reliability of their fastening providing lack of leaks. If collars are not used, make sure that the hose in a junction with the union was not inflated and/or did not harden, allowing leaks. Vacuum hoses Usually vacuum hoses which are especially applied in systems of decrease in toxicity of the fulfilled gases have color marking or inserts from color strips. Various systems demand use of hoses with various thickness of walls, thermal stability and various resistance to a collapse. When replacing hoses you watch that material of a new hose corresponded to material of old. Often only reliable way of check of a condition of a hose is its full removal from the car. At removal more than one hose take care of accurate marking of hoses and unions to provide the correct assembly. When checking vacuum hoses do not forget to check T-shaped plastic connections also. Examine them on existence of cracks which can cause leaks. For identification of leak of vacuum it is possible to use a small piece of a vacuum hose as a stethoscope. Press one end of a hose to an ear and listen another to all vacuum hoses and connections on existence of the characteristic hissing demonstrating vacuum leak.
Fuel hoses
Fuel hoses usually are under pressure therefore at their detachment be ready that fuel will be sprayed and he needs to be collected.
Use only high-quality fuel hoses. Never, under no circumstances use as fuel not reinforced vacuum hoses, transparent plastic tubes or water hoses. For fastening of fuel hoses collars of tape type are usually used. These collars weaken a tension over time and can "jump out" at removal. When replacing hoses replace such collars with collars of screw type. Metal lines Between the fuel pump and system of injection of fuel sections of metal tubes are often inserted. Carefully check these tubes for existence of dents, twisting or cracks. If the section of the metal line needs to be replaced, use only seamless steel tubes since copper and aluminum tubes are insufficiently strong to resist to the vibrations caused by operation of the engine. Check metal brake lines in places of their connection with the main cylinder and with the regulator of pressure or ABS (if it is available) for existence of cracks or the weakened nipple connections. Any signs of leak of brake fluid demand immediate careful survey of all brake system. Hoses of system of hydrostrengthening of a wheel Check hoses of system of hydrostrengthening of a wheel for existence of signs of leak of liquid, the weakened nipple connections and worn-out collars. The proceeding hoses and worn-out collars should be replaced. |
