DIAGNOSIS
SYSTEM LEAKAGE TEST
Tools Required
124 589 15 21 00 Tester
Test Procedure
1. Loosen the cap a little and release pressure and re-
move 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.
3. Connect the special tool to the reservoir filler cap and
apply 1.4 bar of pressure.
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 connec-
tions. Replace or retighten if necessary.
