Water Temperature Gauge
The water temperature gauge shows the temperature of the engine
coolant. Under normal operating conditions the water temperature
gauge should register between 165° and 210° - 225° F (99° and
107° C), depending on the engine. Under certain conditions, some-
what higher temperatures may be acceptable. But the maximum
allowable temperature is 225° F (107° C) with the cooling system
pressurized, except for certain special engines. Check your engine
manual to be sure.
Engine Overheating
Wait until the coolant temperature is below 122° F (50° C). Protect
your face, hands, and arms by covering the cap with a large, thick rag
to protect you against escaping fluid and steam. Before you com-
pletely remove the cap, carefully and slowly turn the cap part way to
allow excess pressure to escape. Then push down and turn for final
removal.
The cooling system may overheat if the coolant level is below normal
or if there is a sudden loss of coolant (such as a worn hose splitting).
It may also temporarily overheat during severe operating conditions
WARNING! Do not remove the radiator fill cap while the
engine is hot. Scalding steam and fluid under pressure may
escape and cause serious personal injuries. You could be
badly burned.
