Under the influence of high temperatures in a motor compartment gradually there is a hardening and destruction of the rubber and plastic hoses which are 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, elasticity loss in such connections owing to swelling or hardening of hoses is not allowed.
Vacuum hoses (almost all treat system of decrease in toxicity) it is possible to distinguish on color, or on the color strips pasted on them. For various systems of the engine vacuum hoses with various in the thickness of walls, mechanical and thermal firmness are used. At replacement track that new vacuum hoses in accuracy corresponded to the replaced.
Often the hose can be checked only after removal from the car. If some hoses act in film, previously put labels on interfaced the union and hoses subsequently not to break their relative positioning.
At check of a condition of vacuum hoses at the same time examine also plastic tees. Check existence on them of cracks, and also hose deformations in a prileganiye place to the union of a tee which can cause tightness violation.
For check of leaks listen through a hose piece, having put it to a 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 on them about bends and in places of fastenings.
At replacement of hoses of the fuel highway new hoses should correspond in accuracy to the replaced.
Metal tubes are usually used in the fuel highway of system of injection. Check existence on tubes braided pressed and cracks.
At replacement it is necessary to establish only seamless steel tubes. Tubes from copper or aluminum do not maintain vibrating 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 leak detection immediately carefully check all system of brakes.
At detection of podtekaniye of liquid replace the damaged hoses of the power steering and their collars.
