PERFORMANCE ORDER
1. Remove the bottom cover of a motor compartment.
2. Put on a hose the drain union of a radiator. In drawing – the engine in volume of 2,0 l.
3. Put on a hose with internal diameter 12 mm the drain union of a radiator. In drawing – the engine in volume of 2,5 l.
4. Establish under a radiator a pure reception vessel, enter into it a hose and open a carving stopper of a drain aperture.

Plums

PERFORMANCE ORDER
1. The engine in volume of 2,0 l: put under the engine a pure vessel and turn out a carving stopper (12) drain apertures on the block of cylinders of the engine.
2. Engines in volume of 2,2/2,5 l: put on a hose with internal diameter 14 mm a carving stopper (4) drain apertures on the block of cylinders of the engine (marksman).
3. Substitute under the engine a pure reception vessel, enter into it a hose and only ослабьте a carving stopper (4) drain apertures, without unscrewing it.
4. Completely lower cooling liquid.
5. Tighten a carving stopper of a drain aperture on the block of cylinders of the engine with the moment 30 Н.м.
6. Twist with the moment 1,5–2,0 Н.м. (Manually) a carving stopper of a drain aperture on a radiator.
7. If насажен remove a drain hose.
8. Establish the bottom cover of a motor compartment.

Gulf

PERFORMANCE ORDER
1. Check up the antifreeze maintenance in a cooling liquid.
2. Fill cooling liquid through a bulk branch pipe of a compensatory tank (2) to a mark (arrow). At the vehicles having a black top part of a tank, prior to the beginning of a black part.

The prevention

That the cooling liquid quickly has got from a compensatory tank to a radiator, and, accordingly, in the engine, it is possible for filling with a cooling liquid to squeeze out downwards a bulk hose.

3. Connect to the storage battery a weight wire.
4. Leave the engine to get warm until the regulator of temperature of a cooling liquid (temperature approximately 100 C) will be opened. Thus establish on a total power heating and pushes press an accelerator pedal.
The prevention

At temperature of a cooling liquid 60–70 C close a compensatory tank.


5. Check up tightness of system of cooling – joinings of hoses, and also carving stoppers of drain apertures.
6. Expose time for hours.
7. Enter an anticreeping code of radio.
