Safety Precautions When Working on the Cooling System

Attention.

• Do not remove the cooling system cap or remove the radiator drain plug while the engine is running or when the engine and radiator are hot. Boiling coolant and steam can escape and cause severe burns. It can also cause damage to the engine and cooling system.
• Switch off the engine and wait until it cools down. Even after that, you need to open the cover of the cooling system with great care. Wrap the cap with a thick cloth and slowly turn it counterclockwise to the first detent position to release excess pressure in the system.
• After the pressure in the cooling system is normalized, press the cover with a cloth and, turning, remove it.
• Depending on the vehicle version, the radiator fan may operate even when the ignition is switched off. Therefore, it is necessary to keep hands and tools away from the fan blades, even when the fan is not running, so as not to cause injury or damage to the fan. Be sure to disconnect the negative battery terminal when servicing the radiator fan or components near it.
