While the engine is cold, the pointer arrow is at the bottom of the scale, the control lamp for the minimum coolant temperature is on. As the engine warms up, the pointer moves up. While the pointer is between the two lower risks of the scale and the control lamp is on, do not allow the engine to run at high speeds.
When the coolant temperature rises above the permissible value, a warning lamp lights up in the instrument cluster. If overheating is temporary and occurred due to forcing the engine, reduce engine speed. The control lamp will go out after a while. If the lamp continues to flash, stop the engine and find the cause of the malfunction, the causes of which may be the following:
- insufficient coolant level;
- the electric fan of the cooling system is faulty or does not turn on;
- the tension is loose or the alternator drive belt is worn out;
- clogged radiator fins
- incorrect ignition timing.
If the malfunction is caused only by a malfunction of the electric fan, then you can continue driving to the nearest workshop, provided that the coolant level is normal and that the indicator lamp has gone out, and the speed is sufficient to cool the engine with oncoming air flow.
