Special tools, testers and auxiliary items required

• Pry Lever - Rmv Outside Mirror (80 - 200)

Removing






• The engine is cold.

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).
