WARNING!
Hot steam can escape from the expansion
tank when the filler cap is opened. Cover the
filler cap with a cloth and unscrew it
carefully.
Note:
When the engine is hot the cooling system
is under pressure. Carefully open filler cap
on expansion tank to release pressure
before starting repair work.
Hoses are secured with spring-type clips.
When repairing only use spring-type clips.
VAG 1921 pliers are recommended when
installing spring-type clips.
The O-rings installed at the quick-release
connections must be replaced if damaged or
leaking.
When installing coolant hoses, make sure
that they are free of stress and do not come
into contact with other components (observe
markings on coolant connection and hose).
Perform leak test on cooling system with cooling
system tester VAG 1274 and adapter VAG
1274/8.
