Cooling system components, removing and installing: Notes

WARNING: Hot steam can escape from the expansion tank when the filler cap is opened. Cover the filler cap with a cloth and remove 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.
