ing system
Caution
When doing any repair work, especially in the engine compart‐
ment, pay attention to the following due to the cramped condi‐
tions:
♦ Route all the various lines (e.g. for fuel, hydraulics, acti‐
vated charcoal filter system, coolant, refrigerant, brake
fluid and vacuum) and electrical wiring in their original po‐
sitions.
♦ To avoid damage to lines, ensure sufficient clearance to
all moving or hot components.
Note
When the engine is warm, the cooling system is under pres‐
♦
sure. If necessary, release pressure before beginning repair
work.
Hoses are secured with spring-type clips. In case of repair,
♦
only use spring-type clips.
Spring-type clip pliers -VAS 6340- are recommended for in‐
♦
stallation of spring-type clips.
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).
