COOLING CIRCUIT INSPECTION

Before removing the radiator and draining the engine coolant,
inspect the cooling circuit for tightness.
• Remove the cowling. (#7-5)
• Remove the radiator cap 1 and connect the radiator tester 2
to the filler.
"
Do not remove the radiator cap when the engine is
hot.
• Give a pressure of about 120 kPa (1.2 kgf/cm², 17.0 psi) and
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 specified pres-
sure, or the radiator can be damaged.
