1.5.15.2. Overheat

GENERAL INFORMATION

The overheat can occur, if:

 – there is an obstacle for a stream of the air blowing in a radiator, leaves, a dust, insects, or the additional headlights established before a front grille can be the reason for that;
 – the boiling point of cooling liquid in view of change of the content of antifreeze was lowered;
 – the fan of cooling of a radiator does not work.

If you cannot define and eliminate the overheat reason, immediately address in a workshop, otherwise there can be a serious breakage of the engine.
