On all models of cars of the considered mark the system of cooling of the closed type, working under pressure is used. Into system structure enter the water pump which drive on l models 1.6 is carried out from газораспределительного a belt, and on other - from auxiliary, the radiator of a cross-section-line design made of aluminium, the electric fan, the thermostat, the heater heat exchanger, and also all connecting armature and electric switches. The cold cooling liquid from a radiator on the bottom hose arrives in the water pump which provides its giving in galleries of the block and a head of cylinders (and also in the heat exchanger of a heater of salon). After selection of heat from surfaces of cylinders, chambers of combustion and saddles of the valves, the cooling liquid reaches the bottom part of the thermostat which in an initial condition is closed. Further, the cooling liquid passes through the heater heat exchanger then comes back back to the water pump.

The function chart of system of cooling of the engine is presented on an accompanying illustration. The cooling system functions as follows: the centrifugal water pump through bottom радиаторный a hose is taken away cold by a cooling liquid from the bottom part of a radiator and under a pressure pumps over it through galleries of a water shirt of the block and a head of cylinders, and at a corresponding complete set also through the heat exchanger маслоохладителя. Having selected heat from cylinders, chambers of combustion and saddles of valves, the liquid gets to the bottom part of the thermostat which valve at a stage of warming up of the engine remains buried, and then opens. Besides the engine cooling, the cooling liquid is used also for heating of salon of the car. With that end in view the heater heat exchanger is included in a path of system of cooling, passing through which, the liquid comes back back in the block of cylinders.

While the engine has not got warm to some certain temperature, the cooling liquid continues to circulate on a short contour, passing only through the block and a head of cylinders, and also through the heater heat exchanger. As soon as the engine temperature reaches the established value, there is a thermostat opening therefore the radiator is connected to a contour of circulation of a liquid. In a radiator there is конвективная a return of heat from a liquid to a running stream of air which efficiency is defined by the developed area of edges of the heat exchanger of a radiator and speed of an air stream flowing round them. It is in case of need provided additional having blown in a radiator at the expense of inclusion of the electric fan of system of cooling. On reaching a liquid of the bottom cavity of a radiator, the cycle repeats.

The electric fan which functioning the thermosensitive gauge-switch of system of cooling operates, is established behind a radiator. As soon as the temperature of a cooling liquid reaches some established value, there is a fan inclusion therefore having blown in the radiator heat exchanger increases that conducts to efficiency increase теплоотдачи.

Safety measures

In avoidance ошпаривания, do not uncover at all a broad tank and do not disconnect any components охладительного a path at the hot engine. If there is a necessity for removal of a cover of a tank before full cooling of a cooling liquid (such situations should be avoided whenever possible), it is necessary to dump preliminary superfluous pressure in system. Wrap up a tank cover a thick layer of rags, then slowly turn on before hissing occurrence. When specifying in release of steam hissing will stop, slowly turn away a cover up to the end. If at last stage отворачивания hissing does not renew, the cover can be removed. In the course of performance of all procedure do not incline the person over a tank mouth, for protection of hands put on rubber gloves.

Try to avoid antifreeze hit on open sites of a skin and a paint and varnish covering кузовных panels. Casual splashes should be washed off immediately plentiful quantity at its finest. At all do not leave merged of the engine or a fresh cooling liquid stored in open container. Passage traces at once collect rags. Remember that the sweetish smell of antifreeze is capable to draw attention of children and animals. Hit even insignificant quantity of a cooling liquid in a digestive path of a live organism is fraught with the most serious consequences, up to a lethal outcome.

Remember that at the hot engine the fan of system of cooling continues to function even after ignition deenergizing - protect hands, try not to suppose hit of hair or clothes edges in contact to blades крыльчатки.

Safety measures for the models equipped with a central air of air, are listed in Section air Central air - the general information and safety measures.
