On the car the liquid system of cooling of the closed type with compulsory circulation of a liquid by means of the centrifugal pump (fig. of the Detail of system of cooling of engines see) is applied. It includes a radiator, the water pump, the thermostat, a broad tank under atmospheric pressure and the fan with вязкостной муфтой. On engines 4D56T the electrofan with plastic крыльчаткой, established on an electric motor shaft is applied, inclusion and which deenergizing is carried out from the gauge of inclusion of the electrofan.

The trubchato-ridge radiator works under the raised pressure.

Pressure of opening of valves of a stopper of a jellied mouth, kgs/sm2:

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

The prevention

Since May, 1991 the integral directing casing of the fan that has 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 basic valve of the thermostat: 76,5 With.
The prevention

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

The centrifugal water pump лопастного type is put in action клиновым by a belt together with the generator. The fan is planted on an axis of the water pump through вязкостную муфту.

The prevention

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

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

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