Repair and car operation

Check of a condition and replacement of the hoses located in an impellent compartment

Performance of replacement of hoses of the K/V refrigerator lines should be left to experts of a workshop of the car-care center, having necessary equipment and possessing the due qualification, allowing to make a safe discharge of system. At all do not disconnect any refrigerator lines until the system will not be completely discharged!

General information

Under the influence of the high temperatures which are taking place in an impellent compartment of the car, the material of the laid in it rubber and plastic hoses starts to collapse eventually. It is necessary to examine regularly all hoses located under a cowl on existence of cracks, traces of leaks, signs of hardening of a material and weakening of shtutserny connections.

Detailed information on check of a condition of hoses of system of cooling of engine/heating of salon is stated in the Section Check of a condition of components of system of cooling.

For fastening of some (but not all) hoses on the unions collars are used. Check reliability of a tightening of shlangovy collars, - weakening of their fastening conducts to development of leaks. If the hose is planted without a collar, make sure that its end remains rather elastic for a dense staving of a surface of the union.

Vacuum hoses

PERFORMANCE ORDER

1. Usually all vacuum hoses which are especially used in systems of decrease in toxicity of fulfilled gases, are marked with a color code, or in their walls вплавлены color strips. In various systems to thickness of walls of vacuum hoses used in them can be made various demands. Hoses should provide various stability to a skhlopyvaniye, temperature influences and other factors. Watch that replaceable hoses answered on the parameters removed from the car.
2. Usually authentically to estimate a condition of a vacuum hose it is possible only having removed it from the car. If it is necessary to remove more than one hose, previously take care of their accurate marking for the purpose of observance of correctness of connection at assembly.
3. During check of a vacuum hose, do not forget to estimate also a condition of its plastic shtutserny connections. Examine the union on existence of cracks and make sure of density of landing of a hose on it. Unevenness of deformation of a hose when landing on the union conducts it to development of losses of depression.
4. The short piece of a vacuum hose in internal diameter about 7 mm is a fine stethoscope by means of which sources of losses of depression rather easily come to light. One end of a hose nestles on the checked surface, the second - to an ear. Losses of depression are always accompanied by hissing.

When listening components try not to touch such moving components in an impellent compartment, as driving belts, blades of a krylchatka of the fan, etc.!

Fuel hoses

PERFORMANCE ORDER

At service of components of a power supply system it is worth to remember that gasoline is easily flammable liquid in the highest measure. Do not smoke near a venue of works, do not come nearer to it with open fire! Immediately collect all traces of the spilled fuel, put the rags impregnated with a fuels and lubricants in such place where the probability of its casual ignition is absolutely excluded! Always hold near at hand the class B fire extinguisher! Try not to allow gasoline hits on open sites of skin - long contact such is capable to lead to development of cancer diseases. Remember that the path of system of injection of fuel constantly is under superfluous internal pressure which should be without fail dumped prior to the beginning of work (see. Head of the Power supply system and release).

1. Check all rubber fuel hoses on existence of signs of aging of a material and other defects. Special attention give to a condition of sites of an excess and the areas located directly ahead of the ends put on unions.
2. As replaceable lines only high-quality fuel hoses should be used. At all it is not necessary to establish not strengthened vacuum hoses, transparent plastic tubes or garden hoses to the power supply system highway.
3. Often for fixing of fuel hoses on unions collars of spring type are used. Such collars lose over time durability of the landing, besides, often unexpectedly come off at the moment of a hose detachment. It will be reasonable to replace such collars more reliable and safe worm or screw.

Metal lines

PERFORMANCE ORDER

1. Sections of metal tubes are often used as fuel lines. Attentively check all rigid fuel lines on existence of dents, excesses and other deformations. Make sure of lack of cracks and signs of the beginning of their education.
2. If any of sections of the metal line is subject to replacement, use as a replaceable only seamless steel tube. Copper and aluminum tubes do not suit use as replacement as do not provide due stability to impact of the vibrations arising in system at operation of the engine.
3. Attentively examine metal brake tubes in places of connection them to GTTs and the valve limiter (if that is provided). Pay attention to such defects as cracks, try to reveal signs of weakening of fastenings. In case of identification of traces of leaks it is necessary to check immediately a condition of all brake system as a whole.
