Systems of cooling, heating and air conditioning

General information

The system of cooling of the engine works at a thermosiphon principle with the water pump and the fan. Systems is tight and works with superfluous pressure that lifts a boiling point of cooling liquid, increasing thereby efficiency of cooling. The cover of a radiator is equipped with the control valve which is not allowing an excessive deviation of internal pressure in system from atmospheric (in both parties).

Cooling liquid at thermal expansion is forced out from a radiator via the valve in a broad tank and when cooling engine after its stop again comes back to a radiator. The management in temperature of cooling liquid carries out the thermostat of voskozapolnenny type. The thermostat is located in a casing fixed on the block of the engine (on models of 3.0 l) or on the inlet pipeline (on models of 4.2 l). For the purpose of prevention of development of corrosion the system of cooling should refuel surely a water mix with antifreeze containing anticorrosive additives.

The drive of the water pump is carried out by a V-shaped belt (the general with the generator) from a pulley of a cranked shaft.
The thermostatic coupling of coupling of the fan is filled with the silicone liquid which viscosity considerably changes with temperature that allows to correct automatically speed of rotation of the fan depending on turns of the engine and intensity of an air stream through a radiator. Losses of engine capacity and intensity of a noise background thus decrease at movement with high speeds

The bimetallic spring in a forward part of the coupling of coupling operates the valve supervising extent of pro-slipping of the fan.

On cars from AT tanks of cooling of transmission oil are built in a radiator.
