WARNING
CAUTION:
COOLANT LEVEL
D
Do not remove the radiator cap when the
engine and radiator are hot. Scalding hot
fluid and steam may be blown out under
pressure, which could cause serious inju-
ry. When the engine has cooled, place a
thick rag or towel over the radiator cap,
slowly rotate the cap counterclockwise to
the detent. This procedure allows any re-
sidual pressure to escape. When the his-
sing sound has stopped, press down on
the cap while turning counterclockwise
and remove it.

The cooling system must be bled of air if
the reservoir tank becomes empty, if air
can be seen in the cooling system, or if
there is a cooling system leak.
Operating the engine with an improperly
bled cooling system can cause overheating
and severe engine damage.
