12–14 COOLING (J05E)
9. INSPECTION FOR COOLANT LEAKAGE
! DANGER
To avoid burns, do not remove the radiator cap when the engine
and the radiator are hot. Pressure causes the liquid and vapor to
burst forth.
(1) Remove the radiator cap, and mount the radiator cap tester.
(2) Perform pumping up to 137 kPa {1.4 kgf/cm
check that pressure does not decrease.
NOTICE
If the pressure decreases, check the hose, radiator, or coolant
pump for leakage. If leakage to the outside is not found, check the
heater core, cylinder block, or cylinder head.
