  Caution
t  When doing any repair work, especially in the engine compartment, pay attention to the following due to the cramped conditions:
t  All the various lines (e.g. fuel, hydraulic system, active carbon filter system, coolant, refrigerant, brake fluid and vacuum pipes and hoses) and electrical wiring must be installed in their original positions.
t  To prevent damaging the hoses, ensure that all mobile or hot components are easily accessible.
  Note
t  When the engine is hot the cooling system is under pressure. If necessary, relieve pressure before commencing repair work.
t  Hoses are secured with spring-type clips. In case of repair, only use spring-type clips.
t  Hose clip pliers -VAS 6340- are recommended for fitting spring-type hose clips.
t  Coolant hoses should be free from tension when installing, so that they do not come into contact with other components (observe markings on coolant connection and hose).
Perform cooling system leakage check with cooling system tester -VAG 1274B- and the adaptor -VAG 1274/8- and the adaptor -VAG 1274/9-.
