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 of 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 opening.

Plums

PERFORMANCE ORDER
1. Engine in volume of 2,0 l: put under the engine a pure vessel and turn out a carving stopper (12) drain openings 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 of 14 mm a carving stopper (4) drain openings on the block of cylinders of the engine (shooter).
3. Substitute under the engine a pure reception vessel, enter into it a hose and only weaken a carving stopper (4) drain openings, without unscrewing it.
4. Completely lower cooling liquid.
5. Tighten a carving stopper of a drain opening on the block of cylinders of the engine with the moment of 30 N of m.
6. Twist with the moment of 1,5-2,0 N of m (manually) a carving stopper of a drain opening on a radiator.
7. If it is got, remove a drain hose.
8. Establish the bottom cover of a motor compartment.

Gulf

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

Prevention

That cooling liquid quickly got from a compensatory tank to a radiator, and, respectively, in the engine, it is possible for filling with cooling liquid to squeeze out down 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 cooling liquid (temperature about 100 ° by C) will be opened. Thus establish on full capacity heating and pushes press an accelerator pedal.
Prevention

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


5. Check tightness of system of cooling – accessions of hoses, and also carving jams of drain openings.
6. Expose time on hours.
7. Enter an anticreeping code of radio.
