Cooling System: Description and Operation

Cooling System


Hot steam may escape when opening the expansion tank cap. Wear protective goggles and protective clothing to prevent damage to eyes and scalding. Cover the cap with a cloth and open very carefully.

• When the engine is warm the cooling system is under pressure. If necessary release pressure before beginning repair work.

• Secure all hose connections using hose clamps appropriate for the model type.

• Hose clip pliers (V.A.G 1921) or spring type clip pliers (VAS 5024 A) are recommended for installing spring clamps.

• Always replace gaskets and seals.

• The arrows on the coolant pipes and coolant hoses must line up across from each other.
