Cooling System: Testing and Inspection

CHECKING COOLING SYSTEM FOR LEAKS






Mount tester 17 0 002 on expansion tank with adapter 17 0 003 and produce 1 bar (14 psi.) pressure.
Cooling system does not have a leak, if there is no considerable pressure drop (max. 0.1 bar or 1.4 psi.) after about 2 minutes.






Assemble radiator cap (1), connector 17 0 004, adapter 17 0 003 and tester
17 0 002, and check the opening pressure of the safety valve.






Lift vacuum valve slightly and check for correct fit.

Check gasket, replacing cap if necessary.
