Apply pressure to the cooling system with a tester, and check if the
pressure drops.
CAUTION:
Higher than the specified pressure may cause radiator damage.
Pressure should not drop.
OK or NG
OK >> GO TO 3.
NG >> Check the following for leak. Refer to CO-11, "
LEAK
CHECK" .
Hose
Radiator
Water pump
3. CHECK RADIATOR CAP
Apply pressure to cap with a tester.
OK or NG
OK >> GO TO 4.
NG >> Replace radiator cap.
