CAUTION
Heater and radiator hoses, and
other engine parts, can be very
hot. Do not touch them. If you
do, you could be burned.
Do not run the engine if the
coolant is leaking. If the vehicle
loses all coolant, it could cause
an engine fire and you could be
burned.
CAUTION
If your engine overheats, see
"Engine Overheating" in
Section 5. Continued operation
of the overheated engine, even
for a short time, may result in
a fire and the possibility of
personal injury and/or severe
vehicle damage.
The cooling system in your vehicle
is designed to use a coolant (a
mixture of ethylene glycol,
corrosion inhibitors and water)
rather than plain water. Use a
50/50 mixture of clean water and
®
DEX-COOL coolant. If you use
this mixture, you don't need to
add anything else.
CAUTION
Adding only plain water or
a liquid other than the
recommended coolant can be
dangerous. The engine could
overheat, but you would not
get the overheat warning. The
engine could catch on fire and
you or others could be burned.
Section 4
NOTICE
If there is too much water in the
coolant mixture, the liquid
could freeze and crack the
engine and other vehicle parts.
NOTICE
The cooling system in your
vehicle is designed to use DEX-
COOL coolant.
Do not substitute any liquids
for the proper coolant mixture.
Otherwise, premature
corrosion may result and the
engine coolant will require
change sooner.
Damage caused by the use
of any coolant that is not
recommended is not covered
by your new vehicle warranty.
