2.6. Check of level of liquids


Because in the course of driving there is a gradual exhaustion of liquid and / or pollution, even at normal operation of the engine, the amount of liquid should replenish periodically. Before check of level establish the car on an equal platform.

Oil level in the engine

Level of oil is checked shchupy which is inserted into a branch pipe of the oil pallet of the engine.

Check oil level on the cold idle engine, or about 15 minutes later from the moment of its stop.
1. Get control щуп from a tube and wipe, insert pure щуп back into a tube and again get. Check level on an oil film which should is between two risks (near the top mark).

2. If level of oil is above the top mark, it will lead to a zamaslivaniye of candles, an oil leak through laying, or to failure of epiploons.
3. To add oil turn out a mouth stopper on a cover of a head of cylinders. After a dolivaniye wrap a cover by hand.

If oil level constantly goes down, the reason are an oil leak through the damaged epiploon, the weakened connections, or through piston rings or directing plugs of valves. If oil gets a dairy shade, or in oil water drops are observed, tightness of laying of a head of cylinders is broken. It indicates need of immediate check of the engine. It is necessary to check an oil condition also regularly. Each time during check of level of oil before wiping щуп, clamp щуп two fingers and carry out on it up. If it is visible that between fingers and shchupy the remains of dirt or small metal particles get stuck, it is necessary to replace oil.

Cooling liquid

All cars considered in this Management, have the closed tight system of cooling of an elevated pressure. The broad tank of white color established behind a radiator, is connected by a hose to the basis of a stopper of a jellied mouth of a radiator. In process of heating of cooling liquid in operating time of the engine there is a replacement of liquid of a jellied mouth in a broad tank. In process of engine cooling cooling liquid flows down back in cooling system. Liquid is added in a tank after stopper removal.

1. On a part of cars the broad tank is mounted on a radiator. Level of liquid (shooter) should be on the cold engine near a mark Low (Nizhny), on the heated-up – Full marks (Full) are slightly lower.
2. On a part of cars the broad tank is mounted sideways in a motor compartment.
3. Add liquid.

Fast falling of level of liquid indicates violation of tightness of system. Check a radiator, hoses, a stopper of a jellied mouth, an inhaling of drain jams, and the water pump. If obvious signs of a leak it is not revealed, check radiator and tank jams, having handed over them in BMW car-care center.

If it is necessary to turn out a stopper of a jellied mouth of a radiator, wait complete cooling of system, then wrap up a stopper a thick layer of rags and turn it to the first emphasis. At emergence of steam wait while liquid will cool down completely, then turn out a stopper.

At an otvorachivaniye of a stopper wait engine cooling (at a stopper otvorachivaniye to the first emphasis of pairs should not leave, a stopper to wind with rags).

Constantly behind a liquid condition. It should be rather transparent. If liquid gained brown color, or color of a rust, it is necessary to replace it, previously having washed out cooling system. Anticorrosive properties are exhausted over time, though liquid and can keep satisfactory appearance.

Liquid of a hydraulic actuator of brakes and coupling

The main cylinder of brakes is mounted in the left part of a motor compartment. The main cylinder of coupling on cars from a manual transmission is nearby, in its right part.
1. Liquid level a tank of a hydraulic actuator of coupling should be about the control cast line or to coincide with it. Otherwise unscrew a stopper and add.
2. Liquid level in a transparent tank of the main brake cylinder should be between Min and Max marks. Otherwise wipe and unscrew a stopper and add liquid.

3. After removal of a stopper of a tank, check existence of pollution in a tank. In the presence of a deposit it is necessary to merge and replace liquid.

After restoration of level of liquid in tanks be convinced of reliability of fastening of jams to avoid leakage of liquid and (or) pressure drop in system.

Level of brake liquid will go down in process of natural wear of brake shoes. Level is restored at replacement of blocks, in use to add liquid does not follow. Gradual fall of level below the bottom mark indicates wear of blocks.

Need of a frequent dolivka of liquid in a tank of the main cylinder of brakes is a leak sign in the brake system which reason it is necessary to eliminate immediately. Check all connections and a condition of tubes and hoses of a brake contour, and also wheel cylinders and the vacuum amplifier.

If at check of level of liquid in a tank of the main brake cylinder absence (or nearly total absence) liquids is revealed, it is necessary to eliminate the reason and to fill system with liquid, having removed from it air.

Liquid of a washer of a windscreen

The tank of a washer of a windscreen is in the right part of a motor compartment.

In a temperate climate the tank of a stekloomyvatel can be filled in with pure water on two thirds. If the car is maintained in a frigid climate, in a tank of a stekloomyvatel it is necessary to fill in solution of special liquid with the lowered freezing point. It is forbidden to fill in in a tank liquid from cooling system.
