On the car the liquid system of cooling of the closed type with compulsory circulation of liquid by means of the centrifugal pump (see fig. is applied. Details of system of cooling of engines). It includes a radiator, the water pump, the thermostat, a broad tank under atmospheric pressure and the fan with the vyazkostny coupling. On engines 4D56T the electrofan with the plastic krylchatka established on a shaft of the electric motor is applied, inclusion and which switching off is carried out from the sensor of turning on of the electrofan.

The tubular and ridge radiator works under an elevated pressure.

Pressure of opening of valves of a stopper of a jellied mouth, kgf/cm2:

– final valve: 0,75-1,05 (it is more or equally 0,65) *;
– inlet valve: it is less or equally 0,05.


Prevention

Since May, 1991 the integral directing casing of the fan that allowed to increase cooling ability of a radiator is established.


The case the thermostat fastens directly to the case of the water pump.

Temperature of opening of the main valve of the thermostat: 76,5 ° Page.
Prevention

On engines 4D56Т the main valve of the thermostat starts to open at temperature 82 ° With and completely opens at temperature 95 ° Page.


The centrifugal water pump of lopastny type is put in action by a maple belt together with the generator. The fan is planted on an axis of the water pump via the vyazkostny coupling.

Prevention

On release engines 4D56 since May, 1991 productivity of the water pump is increased thanks to change of a design of the pump from absorption.


Belt of a drive of the water pump of the Mitsubishi MD159551 brand.

The normal deflection of a belt by pressing with effort of 10,0 kgfs to the branch middle between a pulley of the generator and a pulley of the water pump should be within 10–13 mm.
