Check of a condition and replacement of hoses of an impellent compartment, localization of leaks
|
|
Replacement of lines of communication of central air of air should be made at car repair shop, or in a specialized workshop where there is an equipment for safe dumping of pressure in system. At all do not disconnect hoses of system and do not remove its components, previously without having dumped pressure! |
General information
Influence of high temperatures 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 existence of cracks, weakening of fastening of collars, hardening of materials and signs of leaks.
Additional information on hoses of systems of braking and cooling of the engine is provided in Sections Greasing of universal hinges of driveshafts and Check of components of brake system respectively.

For fastening of the majority of hoses on unions collars are used, - check reliability of their tightening providing due 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 did not harden, allowing leaks.
In case of identification of signs of development of leaks any of the working liquids which origin it is not possible to identify, enclose under the parked car a big leaf of a cardboard and later rather long time study its condition, - потеков it is possible to determine by color and location with high probability the nature and location of leak.

Vacuum hoses
|
|
Usually vacuum hoses which are especially applied in systems of decrease in toxicity of fulfilled gases, it is easy to distinguish on bright color marking. In various systems hoses with various thickness of walls, thermal stability and resistance to a skhlopyvaniye are used, - at replacement of hoses watch that the new hose corresponded on a standard size and execution failed.
Often, the only authentic way of an assessment 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 marking providing unambiguity of their connection at installation into place.
At check of vacuum hoses do not forget to estimate also a condition of T-shaped shtutserny shtutserny connections, examining them on existence capable to cause development of leakages of cracks.
Remember that unevenness of deformation of a hose when landing on the union can give it to development of losses of depression.
Leaks in vacuum lines are meant as the fact of a podsasyvaniye in them of air, i.e., air подсасывается in a hose, instead of leaves it that considerably complicates procedure of localization of a defective site. For identification of places of violation of tightness aurally it is possible to use as a stethoscope 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 existence testifying to existence of leakage of characteristic hissing, - try not to burn about hot surfaces of the power unit and do not touch moving elements in an impellent compartment (a krylchatka of the fan, driving belts, etc.).

Fuel hoses
|
|
At survey or service of components of fuel system it is necessary to observe certain precautionary measures. All works make in well aired room, do not allow approach to a venue of works of open fire (for example, the lit cigarets) or unprotected by the lamp shade of carryings. The spilled 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 away it a 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 a fuel razbryzgivaniye.
|
|
Before starting service of components of a fuel path, it is necessary to dump pressure in system of injection of fuel! |
|
|
Check all rubber fuel hoses on existence of signs of wear and attritions. Special attention give to a condition of bends and sites of an adjunction to shtutserny 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 of an okhladitelny path.
Collars of the tape type which effort of a tightening weakens over time that is interfaced to danger of "soskakivaniye" of 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 localization of leaks in a path of a power supply system is a trudnoosushchestvimy task, - fuel tends to evaporate quickly at contact with air, especially in the warmed-up space of an impellent compartment. At emergence of suspicions on existence of leakages of fuel in an impellent compartment let's to the engine cool down completely, then start it and attentively examine all available топливопроводы, - compression of metal unions when cooling leads to weakening of landing to them rubber hoses that leads to increase in intensity and - as a result - to simplification of localization of taking place leaks.

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

Hoses of system of hydrostrengthening of a wheel
|
|
Check hoses of system of hydrostrengthening of a wheel on existence of signs of development of leakages of liquid, weakening of shtutserny connections and wear of fixing collars. Defective components replace.
|
|
Hoses of system of cooling
|
|
Leaks in system of cooling are usually found by training in places of violation of tightness of a raid of white or red-brown color.
Carefully examine a radiator and a surface of hoses of an okhladitelny path on all their length. Defective components replace.
|
|
Cracks come to light at a hose szhimaniye 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. |
