Note
♦
Cooling system is pressurized when engine is warm. If nec‐
essary, release pressure before carrying out repairs.
♦
Hose connections 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.
♦
Space saving hose clip pliers - VAS 6362- are recommended
for installation of space saving hose clips.
♦
When installing coolant hoses, position them so they are free
of stress and do not come into contact with other components.
♦
The arrows on the coolant pipes and on the ends of the hoses
must be aligned with each other.
♦
Renew gaskets and seals.
Test for leaks in cooling system using cooling system tester -
V.A.G 1274- and adapters - V.A.G 1274/8- and - V.A.G 1274/9- .
