19 – Cooling
1 Parts of cooling system
WARNING
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.
♦ Ensure that there is 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 5024/- or hose clip pliers -V.A.G
1921/- are recommended for installation 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).
Test for leaks in cooling system using cooling system tester -
V.A.G 1274/- and adapter for expansion tank -V.A.G 1274/8- and
adapter for sealing cap -V.A.G 1274/9- .
