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.
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.
|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.
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.
