In the cars equipped with the automatic transmission in the right tank of a radiator the radiator of oil of the automatic transmission is located (type oil - cooling liquid).
Pressure of opening of the valve of elevated pressure in a stopper of a broad tank: 65 – 110 kPa.

Pump of cooling liquid

The centrifugal pump of cooling liquid located on a forward wall of the block of cylinders is put in action by a maple belt together with the generator.

Maple belt

Deflection: 10 mm in the middle of longer site under pressure of a thumb.


It is made of artificial material, has seven blades, it is located on a shaft of the pump of cooling liquid and it is put in action by a maple belt together with the pump and the generator.


Wax, is located on the pipeline which is taking away cooling liquid from a head of the block of cylinders of the engine.

Temperature began opening: 85 ° – 89 °C.

Nominal temperature of opening: 88 °C.

Cooling liquid
