Checking antifreeze and coolant level

Warning
Danger of scalding The coolant gets very hot and is under high pressure when the vehicle is driven.
Do not open the radiator, radiator hoses or other cooling system components when the engine is hot. Allow the engine and
cooling system to cool down. If you scald yourself, hold the affected area under cold water immediately.
Warning
Danger of poisoning Coolants are poisonous and a health hazard.
Avoid contact between coolants and skin, eyes and clothing. If fuel gets into your eyes, rinse immediately with water and
contact a doctor. Wash affected skin areas immediately with soap and water. If coolant is swallowed, contact a doctor
immediately. Change clothes that have come into contact with coolants. Keep coolants out of the reach of children.

The pressure resulting from the warming of the cooling system is regulated by a valve
in the radiator cap . The specified coolant temperature is therefore permissible without
danger of function problems.
120 °C (248 °F)
Cooling is effected by the air stream. The radiator fan provides extra cooling.
The lower the speed, the less the cooling effect. Dirty cooling fins also reduce the cool-
ing effect.
