Check of a condition of components of the cooling system

 PERFORMANCE ORDER

1. The wide range of engine failures is connected with violation of functioning of the cooling system. On the models equipped with AT, this system provides also ATF cooling, supporting by that optimum conditions for work of transmission.
2. Check of a condition of components of the cooling system has to be made after full cooling of the power unit (not less than in three hours after an engine stop).

 Do not uncover a jellied mouth of a radiator at the hot engine at all!

3. Uncover a radiator for what at first turn it to the first emphasis to the left. If the hissing indicating excessive pressure in system is heard wait for its termination, then press a cover a palm down and continue to turn before liberation to the left. Carefully wash out a cover clear water from within and outside. Also wash out a jellied mouth of a radiator. From the cleared surfaces all traces of corrosion have to be completely removed. The cooling liquid which is in system has to be rather transparent. If liquid is painted in color of a rust, the system has to be washed out and filled with fresh mix (see the Section Service of the Cooling System (depletion, washing and filling)). If the level of liquid does not reach top, add in a radiator a little more mix of the required structure (see the Section Check of Levels of Liquids).

4. Attentively examine the top and lower radiator hoses, and also hoses of system of heating of salon, having smaller diameter and located between the power unit and a partition of a motive compartment. Check hoses on all their length and in case of identification of cracks, swellings and signs of aging of material you make replacement of defective components. It is usually simpler to make out small cracks when tightening a hose. Regardless of a state it is necessary to change hoses approximately time in two years.

5. Check reliability of fastening of all hoses on the unions / branch pipes. Leak of cooling liquid is usually shown in the form of potek of rusty or white color on the surfaces surrounding their source. If hoses are fixed on unions/branch pipes by collars of the twisted type, the last will be reasonable to be replaced more reliable worm or screw.
6. Having blown compressed air, or by means of a soft brush, remove from gaps between radiator heat exchanger plates old leaves, remains of insects and other garbage. Try not to damage soft plates of the heat exchanger and not to cut fingers about their keen edges.
7. Every second check, and also at the first signs of violation of functioning of the cooling system you make check of a cover of a radiator pressure. If near at hand there is no suitable equipment, ask for the help on car repair shop.
