COOLING CIRCUIT INSPECTION
Before removing the radiator and draining the engine coolant,
inspect the cooling circuit for tightness.
Remove the cowling. ( W 7 - 5 )
Remove the radiator cap

and connect the radiator tester
@
to the filler.
- -
Do not remove the radiator cap when the engine is
hot.
Give a pressure of about 120 kPa (1.2 kgflcm2, 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.
I
DO not allow the pressure to exceed specified pres-
I
sure, or the radiator can be damaged.
