Check of a condition and replacement of hoses passing under a cowl (each 4800 km (3000 miles) run or times in 3 months)

Hoses, as well as приводные belts, tend to fail at the most inappropriate moment - in order to avoid the troubles connected with unforeseen delays in a way, make check of a condition of hoses as it is possible more carefully, using the map of the most typical defects resulted here.

The general data

Replacement of hoses of a central air of air should be left to experts of dealer branch or a specialised workshop of the car-care centre, having in the order the equipment necessary for a safe discharge of system. At all do not remove any components of system and do not disconnect hoses before carrying out of dump of pressure.

Heats in an impellent compartment can be at the bottom of destruction of a material of the rubber and plastic hoses used in work of the engine, auxiliary units and systems of decrease in toxicity of the fulfilled gases. Hoses should be checked regularly on presence of cracks, signs of easing of collars, hardenings of a material and traces of leaks. The information on check of a condition of hoses of system of cooling is resulted in Section Check of serviceability of system of cooling (each 4800 km (3000 miles) run or times in 3 months).

Some, but not everything, hoses fasten on unions by means of collars. There where collars are applied, check up reliability of their tightening on which the prevention of occurrence of leaks depends. If collars are not used, track, that the hose has not appeared expanded and-or hardened on the site put on the union that usually is at the bottom of leak occurrence.

Vacuum hoses

For identification of the vacuum hoses especially applied in systems of decrease of toxicity of fulfilled gases use of a colour code or introduction in their walls of colour strips is characteristic. Various systems demand application of vacuum hoses of a various thickness of walls on which resistibility схлопыванию under the influence of internal depression and to influence of the raised temperatures depends. At replacement of vacuum hoses watch conformity of a material and a design new removed from the engine.

Frequently, its full removal from the car appears in the unique effective way of check of a condition of a vacuum hose. If to removal are subject more than one hose, take care preliminary of their accurate marks for the purpose of correct installation at assemblage.

Checking a condition of vacuum hoses do not forget as well about plastic tees. Check them on presence of cracks and deformations of sites on which the hose stretches, capable to cause loss of depression as a result of infringement of tightness of a joint.

For revealing of "leaks" of vacuum take advantage of a stethoscope, or - as that - a piece of a vacuum or fuel hose (internal diameter about 6 mm). Hear by means of a stethoscope to hoses (on all length) and them штуцерные connections on presence of the hissing which are a characteristic sign of "leak".

At listening of vacuum hoses by a stethoscope watch to touching moving components of an impellent compartment, such as приводной a belt, fan blades, etc.

Fuel hoses

There are special safety measures which should be undertaken at carrying out of service of components of the power supply system. Work should be made in well ventilated premise. Approach to a place of work with the lighted cigarette, open fire or not protected by a lamp shade redurable is more strict it is forbidden. Casually spilt fuel should gather immediately by means of rags or paper towels which should then develop in inaccessible to fire or sources of heat a place. On инжекторных models the system of injection of fuel is under pressure which should be dumped (more in detail see the Head of the Power supply system and release of the fulfilled gases) before it will be possible to start a detachment of fuel lines.

Check up rubber fuel lines on presence of signs of wiping or material ageing. Especially check up hoses on presence of cracks in places of a bend and on sites directly ahead of unions (as for example on the fuel filter).

High-quality fuel lines are usually marked by inscription Fluroelastomer printed directly on a wall of a hose and should be applied to product of replacements. Do not try to establish at all instead of fuel lines vacuum demanded durability vacuum either water hoses, or transparent plastic tubes.

For fixing of fuel lines on unions collars of spring type are usually used. Such collars often lose the durability eventually, and at removal tend to unexpected соскакиванию. It will be reasonable to replace during replacement of hoses such collars with more reliable of screw (worm) type.

Metal lines

In the power supply system metal lines are often applied. Carefully check up them on presence of excesses, deformations and signs of formation of cracks.

If the section of a metal line is subject to replacement, it is necessary to use for its performance only the steel tubes made on seamless technology as the copper and aluminium do not provide demanded durability for keeping taking place at normal work of the engine of vibrating loadings.

Check up metal brake lines in places of their connection to the main cylinder and the block of alignment of pressure (if that is provided) on presence of cracks or easing signs штуцерных connections. Detection of any signs of leaks in brake lines demands immediate careful check of all brake system.
