CAUTION
Do not run the engine if there is
a leak. All the coolant could leak
out and cause an engine fire.
You could be burned.
NOTICE
This vehicle has a specific cool-
ant fill procedure. Failure to
follow this procedure could
cause the engine to overheat
and be severely damaged.
If coolant is visible in the tank
but is not up to the proper level,
wait a while for the engine to cool,
then add a 50/50 mixture of clean
®
water and DEX-COOL coolant at
the coolant recovery tank to bring
the level to the proper mark.
CAUTION
Under some conditions the
ethylene glycol in engine
coolant is combustible. To
avoid being burned, do not
spill coolant on the exhaust
system or on hot engine parts.
If you have any doubt, have this
operation performed by a
qualified technician.
Section 4
Then replace the cap. Be sure the
cap is tight.
In the case of an overheated
engine condition, or if no coolant
is visible in the recovery tank, see
"Engine Overheating" in Section 5
for the proper fill procedure.
CAUTION
Steam and scalding liquids from
a hot cooling system can blow
out and burn you badly. Never
turn the radiator cap when the
engine and cooling system are
hot.
NOTICE
The radiator cap is a pressure-
type cap and must be tightly
installed to prevent coolant loss
and possible engine damage
from overheating.
