Test Procedure
1. Loosen the cap a little and release pressure and remove
the cap.
Notice
For the risk of scalding, cap must not be opened unless the
coolant temperature is below 90°C.
2. Fill coolant up to upper edge (arrow) of reservoir.
Tester 124 589 15 21 00
4. If the pressure on the tester drops, check leakage at the all
coolant hoses and pipes and each connections. Replace
or retighten if necessary.
