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 to what leaves, dust, insects, or the additional headlights established before a front grille can be the cause;
 – the boiling point of cooling liquid in view of change of content of antifreeze was lowered;
 – the fan of cooling of a radiator does not work.

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