Removing

The coolant system is under pressure when the engine is warm.

Risk of scalding due to hot steam and hot coolant.

Reduce pressure by covering coolant reservoir cap with a cloth and carefully opening.

• Hoses are secured with spring-type clips. In cases of repair only use spring-type clips.

• Hose clip pliers (VAS 6340) are recommended for installing spring-type clamps.

• When installing coolant hoses, make sure they are free of stress and do not come into contact with other components (observe markings on coolant connections and hoses).
