Cooling System Components

Cooling system components

CAUTION!
When doing any repair work, especially in the engine compartment, pay attention to the following due to clearance issues:
^ Route lines of all types (e.g. for fuel, hydraulic, EVAP canister system, coolant and refrigerant, brake fluid, vacuum) and electrical wiring so that the original path is followed.
^ To prevent damage to the lines, make sure there is sufficient clearance to all moving or hot components.

Note:
^ When the engine is warm the cooling system is under pressure. If necessary release pressure before commencing repair work.
^ Secure all hose connections with hose clamps from Parts Catalog.
^ Hose clamp pliers V.A.G 1921 or pliers for spring clamps VAS 5024 A are recommended for installing spring clamps.
^ Always replace gaskets and seals.
^ Arrows on coolant pipes and coolant hoses must line up across from each other.
