WARNING:

When doing any repair work, especially in the engine compartment, due 
to the cramped conditions, pay attention to the following:

NOTE:

z

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

z

Hoses are secured with spring-type clips. In cases of repair only use 
spring-type clips.  

z

VAG 1921 pliers are recommended when installing spring-type clips.  

z

When installing coolant hoses route stress-free, so that they do not come 
into contact with other components (observe markings on coolant 
connection and hose).
