Checking cooling water level in radiator
CAUTION
Do not try to remove the radiator cap when the
•
engine is hot; otherwise you will get burnt. The
cooling water level should be checked before
starting the engine or when the engine is cold.
When removing the radiator cap, loosen it
•
slightly to release the pressure, and then
remove.
Loosen the two radiator cover mounting bolts and
remove the radiator cover.
Remove the radiator cap carefully and check the cooling
water level. If addition of cooling water is needed, add
cooling water to the neck of the fill port.
