COOLING CIRCUIT
INSPECTION
• Remove the radiator cap.
• Connect the tester 1 to the filler.
Do not remove the radiator cap when the engine is
hot.
• Give a pressure of about 120 kPa (1.2 kgf/cm
see if the system holds this pressure for 10 seconds.
• If the pressure should fall during this 10-second interval, it
means that there is a leaking point in the system. In such a
case, inspect the entire system and replace the leaking com-
ponent or part.
When removing the radiator cap tester, put a rag on
the filler to prevent spouting of engine coolant.
Do not allow the pressure to exceed the radiator cap
release pressure, or the radiator can be damaged.
