Check of a condition and replacement of hoses of an impellent compartment, localisation of leaks
|
|
Replacement of lines of communication of a central air of air should be made on a car repair shop, or in a specialised workshop where there is an equipment for safe dump of pressure in system. At all do not disconnect hoses of system and do not remove its components, preliminary without having dumped pressure! |
The general information
Influence of heats in an impellent compartment leads to gradual failure of the rubber and plastic hoses used in various systems. It is necessary to make regularly check of hoses on presence of cracks, easing of fastening of collars, hardening of materials and signs of leaks.
The additional information on hoses of systems of braking and engine cooling is resulted in Sections Greasing of universal hinges карданных shaft and Check of components of brake system accordingly.

For fastening of the majority of hoses on unions collars are used, - check up reliability of their tightening providing due hermetic sealing of landing of a hose. In certain cases fastening of hoses by collars is not provided, - make sure that the hose in a place of landing to the union was not inflated and-or has not hardened, supposing leaks.
In case of revealing of signs of development of leaks any of the working liquids which origin it is not possible to identify, enclose under the parked car the big sheet of a cardboard and after long enough time study its condition, - on colour and a site потеков it is possible to define the nature and a leak site with high probability.

Vacuum hoses
|
|
Usually vacuum hoses especially applied in systems of decrease of toxicity of fulfilled gases, it is easy to distinguish on bright colour marks. In various systems hoses with various thickness of walls, thermal stability and resistance схлопыванию are used, - at replacement of hoses watch that the new hose corresponded on a standard size and execution failed.
More often, unique authentic way of an estimation of a condition of a hose is its removal from the car. At removal more than one hose take care of drawing of the accurate marks providing unambiguity of their connection at installation into place.
At check of vacuum hoses do not forget to estimate also a condition T-shaped plastic штуцерных connections, examining them on presence capable to cause development of leaks of cracks.
Remember that non-uniformity of deformation of a hose at its landing to the union can result to development of losses of depression.
The fact is meant leaks in vacuum lines подсасывания in them of air, i.e., air подсасывается in a hose, instead of leaves it that appreciably complicates procedure of localisation of a defective site. For revealing of places of infringement of tightness on hearing it is possible to take advantage as a stethoscope of a small piece of the same vacuum hose. At the engine started on single turns hear to all vacuum hoses and places of their connection of connection on presence testifying to presence of leak of characteristic hissing, - try not to burn about hot surfaces of the power unit and do not touch moving elements in an impellent compartment (крыльчатка the fan, приводные belts, etc.).

Fuel hoses
|
|
At survey or service of components of fuel system it is necessary to observe certain safety measures. All works make in well aired premise, do not suppose approach to a place of work of open fire (for example, the lighted cigarettes) or not protected by a lamp shade a resock. The spilt fuel immediately collect rags, putting it then in a place where the impossibility of its spontaneous ignition will be guaranteed. At fuel hit on open sites of a body immediately wash off its plentiful quantity of water with soap. Do not forget to put on goggles, always hold near at hand the fire extinguisher! |
Fuel usually is in a power supply system path under pressure, therefore at a detachment of hoses take measures against разбрызгивания fuel.
|
|
Before to start service of components of a fuel path, it is necessary to dump pressure in system of injection of fuel! |
|
|
Check up all rubber fuel hoses on presence of signs of deterioration and attritions. Special attention give to a condition of bends and adjunction sites to штуцерным to sockets (the fuel pump, the filter and so forth).
Apply only high-quality fuel hoses. Under no circumstances do not use as fuel not reinforced vacuum hoses, transparent plastic tubes or hoses охладительного a path.
Collars of the tape type which effort of a tightening weakens in due course that is interfaced to danger соскакивания a collar at removal are usually applied to fastening of fuel hoses on unions, - be careful. At replacement of hoses such it will be reasonable to replace a collar worm. Or screw.
At the initial stage of development localisation of leaks in a power supply system path is трудноосуществимой a problem, - fuel tends to evaporate quickly at contact with air, especially in разогретом space of an impellent compartment. At occurrence of suspicions on presence of leaks of fuel in an impellent compartment allow to the engine to cool down completely, then start it and attentively examine all accessible топливопроводы, - compression of metal unions at cooling leads to weakening of landing to them of rubber hoses that leads to increase in intensity and - as consequence - to simplification of localisation of taking place leaks.

Metal lines of paths of brake system and the power supply system
|
|
On sites of a working path of the power supply system between the fuel pump and injection system metal tubes which also should be examined attentively are often inserted, checking on presence of deformations, twisting, cracks and other mechanical damages.
For replacement of defective sections use only seamless steel tubes, - copper and aluminium tubes do not provide due resistibility to influence of the vibrations, arising at engine work.
Check metal brake lines in places of their connection to ГТЦ, to a regulator of pressure or hydromodulator ABS (at a corresponding complete set) on presence of cracks and easing signs штуцерных connections. Revealing of any signs of leaks of a brake liquid demands immediate complex survey of all brake system.

Hoses of system of hydrostrengthening of a wheel
|
|
Check up hoses of system of hydrostrengthening of a wheel on presence of signs of development of leaks of a liquid, easing штуцерных connections and deterioration of fixing collars. Defective components replace.
|
|
Hoses of system of cooling
|
|
Leaks in cooling system are usually found out by training in places of infringement of tightness of a touch of white or red-brown colour.
Carefully examine a radiator and a surface of hoses охладительного a path on all their length. Defective components replace.
|
|
Cracks come to light at сжимании a hose is easier. Special attention give to a condition and reliability of a tightening of collars of fastening of hoses to connecting branch pipes of elements of system of cooling. Pulling of collars is interfaced to risk of formation of cuts and ruptures of hoses. |
