2.12. Check and replacement of hoses in a motor compartment
The prevention Under the influence of heats 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, presence on them of cracks and hardening, easing of connections, tightness infringement. The procedure for test of hoses of system of cooling and brakes is described in corresponding subsections (subsection 2.24 and subsection 10.15 see). Almost all hoses fasten by means of collars. Check durability of an inhaling of collars as fastening easing leads to tightness infringement. 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 supposed. Vacuum hoses (almost all concern system of decrease in toxicity) it is possible to distinguish on colour, or on the colour 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. Frequently the hose can be checked up only after removal from the car. If some hoses act in film, preliminary 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 up presence on them of cracks, and also hose deformations in a place прилегания to the union of a tee which can cause tightness infringement. For check of leaks listen through a hose piece, having put it to a checked place. Characteristic "hissing" will specify in leak presence. At a detachment of fuel hoses keep in mind that fuel can be in them under pressure. Check up a condition of rubber fuel hoses, presence on them of cracks about bends and in places of fastenings. At replacement of hoses of a fuel highway new hoses should correspond in accuracy to the replaced. Metal tubes are usually used in a fuel highway of system of injection. Check up presence on tubes braided pressed and cracks. At replacement it is necessary to establish only seamless steel tubes. Tubes from copper or aluminium do not maintain vibrating loadings. Check up a condition of metal tubes and unions of system of a hydrodrive of brakes in junctions with the main brake cylinder and дозатором (if it is provided), presence of cracks and ослабших connections it is not supposed. At leak detection immediately carefully check up all system of brakes. At detection подтеканий liquids replace the damaged hoses of the hydraulic booster of a wheel and their collars. |
