Cooling liquid
1. Leak in cooling system is usually found out on white or colours of a rust to a touch in the area adjoining leak.
2. Carefully check up a radiator and hoses of a cooling liquid on all length. Replace hoses with cracks, ruptures and ageing signs. Cracks are easier for finding out if to press a hose. Will pay special attention on collars which attach hoses to elements of system of cooling. Collars of fastening of a hose which have been strongly tightened, can cause rupture or a hose puncture, leaks in cooling system will be result of that.
3. Examine all components of system of cooling (hoses, surfaces of sockets etc.) about leaks. If any problems of similar character with system components replace this component or a lining are found out.


Fuel leaks precisely to define difficultly while leak does not become essential and, hence, 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, rubber hoses tend to be weakened, so any leaks will be more obvious, while the engine heats up from start from a cold condition.

1. Check up all connections топливопроводов to a fuel highway, a fuel regulator of pressure and the fuel filter. Check up each rubber fuel hose on all length on presence of ruptures or cracks. Check up leaks from the goffered connections between rubber and metal топливопроводами. Check up connections between metal топливопроводами and a casing of the fuel filter. Also check up area round fuel atomizers on a sign of ring leak.
2. To define fuel leaks between a fuel tank and a motor compartment, the car is necessary for lifting. Examine a tank and a hose of a jellied mouth on punctures, cracks and other damages. This connection is especially unreliable.
3. Carefully check up all rubber hoses and metal топливопроводы, departing from a tank. Check up the weakened connections, the worsened 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 труднозаполняемым. Follow for топливоподачей and returnable hoses to переду the car, carefully examining them completely on damage or corrosion signs. Change the damaged sections as required.

Engine oil

Examine area round a cover of a head of the block of cylinders, the oil filter and surfaces of a socket of the pallet. Keep in mind that eventually in this area there can be very small leak and consequently that you really search, these are signs of the serious leak caused by rupture of a lining. The engine oil filtering from under a cover of a gear belt of a drive or картера couplings can be a sign of deterioration of sealing rings коленвала or an entrance shaft of a transmission. If leak is found, replace a defective lining or oil consolidation.

Oil for automatic transmission

Check up the hoses conducting to a cooler of oil ahead of a motor compartment about leak. Search for the defects caused by corrosion and damage from contact with the earth or a dirt, the road rejected from a surface. Transmissionnoe oil of usually red colour.

Liquid in system of the amplifier of a steering

1. Check up a hose located between a nutritious tank and the pump of the amplifier of a steering and a returnable hose, from a shelf of management to a nutritious tank. Also check up a high pressure hose between the pump and a management shelf.
2. Check up the hoses conducting to a cooler of a liquid ahead of a motor compartment (in some models). Search for the defects caused by corrosion and damage from contact with the earth or a dirt, the road rejected from a surface.
3. Will pay special attention on the goffered connections and the area surrounding hoses which are fixed with regulated скобами steering transfer. Similarly трансмиссионному to oil, this liquid of red colour.

Air conditioner (cooling means)

Air central air is filled by the cooling liquid which is under a high pressure. If air central air is opened and depressurized without the aid of the special equipment, the liquid will immediately evaporate. If the liquid contacts with your skin, it can cause serious обморожение.

About all suspicious leaks of a central air of air dealer Peugeot or the expert in air conditioners should be immediately warned. Leak can be found out on appreciable steady decrease in level of a cooling liquid.

The prevention

Moisture occurrence on a drainage pipe of the condenser (газоохладителя) under the car right after conditioner uses – the normal phenomenon also should not cause for anxiety.

Brake liquid

Brake liquid – poisonous substance with a watery consistence. The new liquid almost colourless, but it darkens in due course and at a heavy use.

1. Check up area of connection of brake tubes with the main brake cylinder about leak. Check up area round the basis of a nutritious tank on signs of the leak caused by defect of a lining. Also investigate муфты the brake pipeline in hydrodevice ABS.
2. If liquid loss is obvious, but leak cannot be precisely defined, the motor compartment, a support of brakes and a tube of brake system should be checked carefully up on the lifted car. Leak of a liquid from brake system – serious damage which should be corrected immediately.

The neolearnt leaks of liquids

If there are signs of 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 following liquid on colour. But keep in mind that some leaks can be shown only at the working engine.

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 will reduce efficiency of brake system.

Besides, many of components, especially components of management of issue, are put in action from the vacuum created in an inlet collector through hoses of small section. 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: hold one end of a hose close to an ear (but not in 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 a hose. It is necessary to avoid contact to hot and moving details since the engine at check should work. Replace all found not tight vacuum hoses.
