COOLING CIRCUIT INSPECTION

Before removing the radiator and draining the engine coolant,
inspect the cooling circuit for tightness.
• Remove the fuel tank. (#6-3)
• Remove the left frame head cover. (#9-6)
• Remove the radiator cap 1 and connect the tester 2 to the
filler.
"
Do not remove the radiator cap when the engine is
hot.
• Give a pressure of about 110 kPa (1.1 kgf/cm², 15.6 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 the radiator cap
release pressure, or the radiator can be damaged.
