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 cooling of ATF, supporting thereby optimum conditions for transmission functioning.
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 / a broad tank 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 from within and outside clear water. Also wash out jellied mouths of a radiator and broad tank. 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 Check of a State and Replacement of Cooling Liquid of the Engine). If the level of liquid does not reach top, add a little more mix of the demanded structure in a radiator.
4. Attentively examine the top and lower radiator hoses, and also the hoses of system of heating of salon having smaller diameter and located between the power unit and a back 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 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.

Check hoses for existence of the wiped sites

The softening of rubber testifies to the beginning of its destruction as a result of aging

Too hard tightening of a collar for the purpose of more reliable fixing on an union/branch pipe of the hardened hose does not promote the leak termination, and only leads to hose material destruction

Check all hoses for existence of swellings and traces of infiltration of oil at end faces (cracks and small breaks in rubber come to light when tightening a hose easier)

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. By blowing off by 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. For check of a cooling path pressure kill the engine, fill a radiator with cooling liquid and attach a radiator cover tester to a jellied mouth, - try not to damage the last. Wipe a surface of a radiator and components of a cooling path pure rags, having completely removed from them dirt and traces of potek. Create pressure in 157 kPas (1.6 kgfs/cm 2) and attentively examine all sections of a radiator, and also nipple sockets of a cooling path on existence of signs of development of leaks, in case of need tighten the weakened nipple sockets, make recovery repair / replacement of the damaged components.

8. Every second check, and also at the first signs of violation of functioning of the cooling system make check of a cover of a radiator pressure. Previously examine a cover on existence of signs of development of corrosion and mechanical damages. By means of a special tester check serviceability of functioning of the safety valve of a cover. Increase pressure until the arrow of the device does not stop, - pressure above limit service value (83 kPas) has to be kept by a cover within not less than 5-6 seconds. At negative results of check replace a cover. Standard value of pressure of opening of the valve of a cover of a radiator makes 93 ÷ 123 kPas.

9. If at a temperature of cooling liquid over 76-80 °C the radiator remains cool to the touch, check serviceability of functioning of the thermostat (see the Head of the Cooling system, heating). If the thermostat does not open at 76-80 °C, make its replacement.
10. If at a temperature of cooling liquid of 90-94 °C the cooling system fan is not activated, check serviceability of functioning of a thermoswitch / a driving electric motor of the fan.
