1.5.1. Cooling system fan

GENERAL INFORMATION

The fan of the cooling system has the drive from the engine by means of a maple belt with ribs. Frequency of rotation of the fan is regulated by the visko-coupling depending on temperature of cooling liquid.

Besides, depending on model of the installed engine and a complete set of the car (for example, existence of the automatic transmission of the traction coupling device installed at manufacturer, climatic installation) in the cooling system of the engine there can be a computer-controlled additional electric fan.


Prevention

After an engine stop the fan can still some time (up to 10 minutes) to rotate – as well after switching off of ignition.
The stopped fan can also after some time suddenly again begin to rotate if:

 – temperature of cooling liquid because of difference of temperatures in the engine increased;
 – at the hot engine air temperature in a motor compartment because of intensive sunlight increased.
