1.5.1. The fan of system of cooling

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

Besides, depending on model of the established engine and a car complete set (for example, presence of an automatic transmission of the tjagovo-drawbar established on manufacturer, climatic installation) in system of cooling of the engine can be the additional computer-controlled electrofan.

The prevention

After a stop of the engine the fan can still some time (till 10 minutes) to rotate – as well after ignition deenergizing.
The stopped fan can also after some time suddenly again start to rotate, if:

 – The temperature of a cooling liquid because of difference of temperatures in the engine has raised;
 – At the hot engine air temperature in a motor compartment because of an intensive sunlight has raised.
