COOLING AND LUBRICATION SYSTEM 7-3

COOLING CIRCUIT

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 radiator cap

and connect the tester

to the

filler.



• Give a pressure of about 120 kPa (1.2 kgf/cm², 17 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.

Do not remove the radiator cap when the engine is
hot.

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.
