Engine Coolant
The cooling system in the vehicle is ?lled with
DEX-COOL
engine coolant. This coolant is designed
to remain in the vehicle for ?ve years or 150,000 miles
(240 000 km), whichever occurs ?rst.
The following explains the cooling system and how to
check and add coolant when it is low. If there is a problem
with engine overheating, see Engine Overheating on
page 5-32.
What to Use
{ CAUTION:
Adding only plain water to the cooling system can
be dangerous. Plain water, or some other liquid
such as alcohol, can boil before the proper coolant
mixture will. The vehicle?s coolant warning system
is set for the proper coolant mixture. With plain
water or the wrong mixture, the engine could get
too hot but you would not get the overheat
warning. The engine could catch ?re and you or
others could be burned. Use a 50/50 mixture of
clean, drinkable water and DEX-COOL
coolant.
Use a 50/50 mixture of clean, drinkable water and
DEX-COOL
coolant. If using this mixture, nothing else
needs to be added. This mixture:
? Gives freezing protection down to ?34F (?37C),
outside temperature.
? Gives boiling protection up to 265F (129C),
engine temperature.
? Protects against rust and corrosion.
? Will not damage aluminum parts.
? Helps keep the proper engine temperature.
Notice: If an improper coolant mixture is used,
the engine could overheat and be badly damaged.
The repair cost would not be covered by the vehicle
warranty. Too much water in the mixture can freeze
and crack the engine, radiator, heater core, and
other parts.
Notice: If extra inhibitors and/or additives are used
in the vehicle?s cooling system, the vehicle could
be damaged. Use only the proper mixture of
the engine coolant listed in this manual for the
cooling system. See Recommended Fluids and
Lubricants on page 6-11 for more information.
