2.16. Check of hoses, tubes and their replacement

Check of metal pipelines about a fuel tank

The arrangement of metal pipelines is specified by an arrow.

Heats in a motor compartment can lead to deformation of rubber and plastic hoses, their periodic check and replacement therefore is necessary.

For fastening of hoses on connections it is recommended to use screw collars instead of spring which are less reliable.

The neolearnt leaks of liquids

If there are signs that there is a leak of any liquid, but you cannot distinguish type of a liquid or an exact origin it is necessary to leave the car for long time and to put the big piece of a paper or a rag under the car. It will help to find a place of course of a liquid, and also will help to identify a followed liquid on colour. But keep in mind that some leaks can be shown only at the working engine.

Fuel hoses

Fuel leak precisely to define very difficultly while leak is not becomes essential and, hence, it is easily visible. Fuel tends to evaporate quickly as soon as it contacts with air, especially in a hot motor compartment. Small drops can disappear before you can define a leak place. If you suspect that there is a leak of fuel in the field of a motor compartment then cool the engine and start it, while it cold at an open cowl. Metal elements tend to be compressed in a cold condition, and rubber hoses tend to be weakened, so any leaks will be more obvious, while the engine heats up from start from a cold condition.

Carefully check up all rubber hoses and metal топливопроводы, departing from a fuel tank. Check up the weakened connections, the worn out hoses twirled топливопроводы and other damages. Will pay special attention on pipes of ventilation and hoses which are often overwound round a hose of a jellied mouth and can be blocked, doing a tank difficultly filled. Follow for топливоподающими and returnable hoses to a forward part of the car, carefully examining them completely on signs of damages or corrosion.

Vacuum hoses

In spite of the fact that the brake system hydraulic, the amplifier of brakes increases the effort applied on a brake pedal, using vacuum in the inlet collector, created at engine work. The vacuum is transferred to the amplifier through a hose of the big section. Any негерметичность this hose reduces efficiency of brake system.

Leak in a vacuum hose means that air is sucked in in a hose, instead of leaves a hose, and it does leak very difficult for detection. The detection method consists in using an old vacuum hose, as some kind of a stethoscope. Thus hold one end of a hose close to an ear, and other end use to investigate area round prospective leak. When the hose end will be directly over the leak place, the hissing sound will be clearly audible through an additional hose. It is necessary to avoid contact to hot and moving details as the engine at check should work. Replace all found not tight vacuum hoses.

Metal pipelines

For replacement it is necessary to use only steel tubes as copper or aluminium tubes do not provide sufficient durability.

Metal pipelines are often used in fuel system. Check up, that the pipeline has not been pressed, deformed, had no cracks and corrosion traces (fig. Check of metal pipelines about a fuel tank see).

Metal brake pipelines also should be checked carefully on presence of cracks and density of connections. At detection of traces of a brake liquid it is necessary to check up a condition of brake system immediately.
