D. Return the engine speed to normal idle after two or three
minutes.
E. Monitor the engine temperature. After the temperature
returns to normal, allow the engine to idle 3 to 5 minutes
before shutting it off. This allows the engine to cool grad-
ually and uniformly.
• If the overheating came from severe operating con-
ditions, the temperature should have cooled by this
time.
F. Check the level of coolant in the coolant expansion tank
(engine compartment, right side.)
WARNING! Removing the radiator fill cap while
the engine is hot can be dangerous. Never
remove the caps of the expansion tank while the
engine is still hot; you could be badly burned.
• Scalding steam and fluid under pressure may
escape and cause serious personal injuries.
• 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 against escap-
ing fluid and steam.
WARNING! Carefully and slowly turn cap one
turn to allow excess pressure to escape, then
push down and turn for final removal.
G. See
page 151
for instructions on checking and filling the
coolant expansion tank.
