While the engine is cold, the pointer is at the bottom of the scale, and the minimum coolant temperature indicator light is on. As the engine warms up, the pointer moves up. While the pointer is between the two lower marks on the scale and the indicator light is on, do not allow the engine to run at high speeds.
When the coolant temperature rises above the permissible level, the control lamp lights up in the instrument cluster. If the overheating is temporary and occurred due to forcing the engine, reduce the engine speed. The control lamp will go out after a while. If the lamp continues to flash, stop the engine and identify 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 alternator drive belt is loose or worn out;
- the radiator fins are clogged;
- incorrect ignition timing.
If the fault is caused only by incorrect operation of the electric fan, you can continue driving to the nearest service station, provided that the coolant level is normal and that the indicator lamp has gone out, and the driving speed is sufficient to cool the engine with the oncoming air flow.
