Engine overheating

If the pointer goes into the red zone only briefly, this is normal for the following operating conditions: at maximum speed, driving uphill or in a column in hot weather, after a hot engine has been stopped, in «traffic jam» by car with automatic transmission (due to the transmission oil cooler - to prevent this, you need to shift the lever to N·mode more often).

If the temperature gauge is in the red zone, stop, turn off the engine and check the following:

• integrity of the coolant pump drive belt;
• coolant level;
• check the thermostat, if it is jammed, the radiator will be noticeably colder than the thermostat housing;
• whether the fan turns on.

If all checks show no problems, the radiator is clogged and should be replaced.
