2.4.1. Device

Engines of cars of Hyundai are equipped with circulating system of cooling. For circulation of cooling liquid the centrifugal pump serves. The system of cooling of the engine consists of a shirt of cooling, a radiator with the electrofan, the centrifugal water pump, the thermostat and hoses. The system of cooling works with a separate broad tank.
The contour of cooling liquid has thermostatic management. While the engine cold, cooling liquid circulates only in a head of the block of cylinders, and also in the block of cylinders and the heat exchanger. In process of engine warming up the thermostat opens a big contour of system of cooling. Cooling liquid starts to move constantly working pump through a radiator of system of cooling. Cooling liquid passes through a radiator from top to down and is thus cooled passing between radiator plates air.
When the temperature of cooling liquid is in a range between +92... +97 °C, the thermoswitch is included by the radiator electrofan. The electrofan is put in action by the electric motor and works until the temperature of cooling liquid will not fall below +84... +91 °C.

Components of system of cooling
Fig. 2.172. Components of system of cooling



ATTENTION
The electrofan of a radiator can turn on and at the switched-off ignition. Because of heat in a motor compartment it can occur several times.

Thanking not constantly working fan useful engine capacity increases and fuel consumption decreases.
The Beskorpusny thermostat of system of cooling has a firm thermosensitive filler.
Radiator of system of cooling tubular and lamellar, aluminum, with plastic tanks. Cooling liquid is filled in in system through a bulk mouth of the broad tank which stopper has inlet and final valves.

Check of a technical condition
Check pipelines and hoses of system of cooling on existence of cracks, damages and reduction of section through passage.
If necessary replace defective details.

Assembly

The scheme of installation of the bringing pipeline
Fig. 2.173. The scheme of installation of the bringing pipeline


Insert a sealing ring into a flute on the end of the bringing pipeline, moisten a sealing ring with cooling liquid and attach bringing pipeline to the block of cylinders (fig. 2.173).
Be convinced available labels of yellow color on a bringing hose and attach the hose end with a yellow label by the end of the bringing pipeline with a yellow label.

NOTE
Do not put oil or greasing on a sealing ring of the bringing pipeline.
The bringing pipeline should be inserted into a nest in the block of cylinders against the stop.
The removed sealing rings repeatedly are not used and is subject to replacement with the new.
