Under the influence of high temperatures in a motor compartment gradually there is a hardening and destruction of the rubber and plastic hoses ensuring functioning of various units of the engine. It is necessary to check periodically a condition of hoses, existence on them of cracks and hardening, weakening of connections, tightness violation.
Almost all hoses fasten by means of collars. Check durability of an inhaling of collars as weakening of fastening leads to tightness violation. In those places in which collars are not provided check reliability of consolidation of a hose on unions, loss of elasticity in such connections owing to swelling or hardening of hoses is not allowed.
Vacuum hoses (almost all treat system of decrease in toxicity) can be distinguished on color, or on the color strips pasted on them. For various systems of the engine vacuum hoses with various thickness of walls, mechanical and thermal firmness are used. When replacing track that new vacuum hoses in accuracy corresponded to replaced.
Often the hose can be checked only after removal from the car. If several hoses are removed, then previously put tags on interfaced the union and hoses subsequently not to break their relative positioning.
When checking a condition of vacuum hoses examine also plastic tees at the same time. Check existence on them of cracks, and also deformations of a hose in the place of a prileganiye to the tee union which can be a tightness cause of infringement.
For check of leaks listen through a hose piece, having put it to the checked place. Characteristic "hissing" will indicate leak existence.
At a detachment of fuel hoses keep in mind that fuel can be in them under pressure.
Check a condition of rubber fuel hoses, existence of cracks for them about bends and in places of fastenings.
When replacing hoses of the fuel highway new hoses have to correspond in accuracy to replaced.
Metal tubes are usually used in the fuel highway of system of injection. Check existence on the tubes twisted pressed and cracks.
When replacing it is necessary to establish only seamless steel tubes. Tubes from copper or aluminum do not maintain vibration loadings.
Check a condition of metal tubes and unions of system of a hydraulic actuator of brakes in junctions with the main brake cylinder and the batcher (if it is provided), existence of cracks and the weakened connections is not allowed. At detection of a leak immediately carefully check all system of brakes.
At detection of dribbles of liquid replace the damaged hoses of the power steering and their collars.
