Check of a condition and replacement of hoses of an impellent compartment

Replacement of hoses of a central air of air should be made on a car repair shop of dealer branch or in a specialised workshop where there is an equipment for safe dump of pressure in system. Never 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 information concerning hoses of system of cooling, is resulted in Section Check of functioning of system of cooling, and in hoses of brake system - in Section Check of brake system.

The majority of hoses (but not all) fasten by means of collars. There, where collars are used, check up reliability of their fastening providing absence of leaks. If collars are not used, make sure that the hose in a junction with the union was not inflated and-or has not hardened, supposing leaks.

Vacuum hoses

Usually vacuum hoses especially applied in systems of decrease of toxicity of fulfilled gases, have colour marks or inserts from colour strips.

Various systems demand use of hoses with various thickness of walls, thermal stability and various resistance схлопыванию. At replacement of hoses watch that the material of a new hose corresponded to a material of the old.

Often unique authentic way of check of a condition of a hose is its full removal from the car. At removal more than one hose takes care of accurate marks of hoses and unions to provide correct assemblage.

At check of vacuum hoses do not forget to check up T-shaped plastic connections also. Examine them on presence of cracks which can cause leaks.

For revealing of leaks of vacuum it is possible to take advantage of a small piece of a vacuum hose as a stethoscope. Press one end of a hose to an ear and hear another to all vacuum hoses and connections on presence of the characteristic hissing testifying to leak of vacuum.

Using a similar stethoscope, be cautious, do not suppose contact to moving components in an impellent compartment, such as приводной a belt, the cooling fan, 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 of open fire (for example, the lighted cigarettes) or the bulbs not protected by a lamp shade to a work place. The spilt fuel immediately collect rags which put then in a place where its spontaneous ignition is impossible. At fuel hit on a skin immediately wash off its plentiful quantity of water with soap. At work with fuel system it is necessary to use goggles and always to have near at hand the fire extinguisher.

Fuel hoses usually are under pressure, therefore at their detachment be ready to that fuel will be sprayed also it it is necessary to collect.

On the cars equipped with system of injection of fuel before to serve fuel hoses, it is necessary to dump pressure in system.


Check up all rubber fuel hoses on presence of signs of deterioration and attritions. Pay special attention on sites of a bend and in front of unions, for example a junction of a hose with the fuel pump or the filter, cracks there can be formed.

Use only high-quality fuel hoses. Never, under no circumstances do not use as fuel not reinforced vacuum hoses, transparent plastic tubes or water hoses.

For fastening of fuel hoses collars of tape type are usually used. These collars weaken in due course a tension and can "jump out" at removal. At replacement of hoses replace such collars with collars of screw type.

Metal lines

Between the fuel pump and system of injection of fuel sections of metal tubes are often inserted. Carefully check these tubes on presence of dents, twisting or cracks.

If it is necessary to replace section of a metal line, use only seamless steel tubes, since copper and aluminium tubes are insufficiently strong to resist to the vibrations caused by work of the engine.

Check metal brake lines in places of their connection with the main cylinder and with a regulator of pressure or ABS (if it is available) on presence of cracks or weakened штуцерных connections. Any signs of leak of a brake liquid demand immediate careful 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 leak of the liquid, weakened штуцерных connections and the worn out collars. It is necessary to replace proceeding hoses and the worn out collars.
