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

Discharge

PERFORMANCE ORDER
1. 2,0 l engine: put a pure vessel under the engine and turn out a carving stopper (12) of a drain opening on the block of cylinders of the engine.
2. 2,2 / 2,5 l engines: put on a hose with an internal diameter of 14 mm a carving stopper (4) of a drain opening on the block of cylinders of the engine (shooter).
3. Substitute a pure reception vessel under the engine, enter into it a hose and only weaken a carving stopper (4) of a drain opening, 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 m 30 N.' moment.
6. Twist with the moment 1,5–2,0 N. of m (manually) a carving stopper of a drain opening on a radiator.
7. If it is got, then remove a drain hose.
8. Establish the lower 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 compensation 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 compensation tank to a radiator, and, respectively, to the engine, it is possible to squeeze out for filling with cooling liquid a bulk hose down.

3. Connect a weight wire to the rechargeable battery.
4. Leave the engine to get warm until the regulator of temperature of cooling liquid is opened (temperature about 100 °C). At the same time establish at full capacity heating and pushes press an accelerator pedal.
Prevention

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


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