Engine Coolant
The cooling system in your vehicle is filled with
DEX-COOL
®
engine coolant. This coolant is
designed to remain in your vehicle for five years or
150,000 miles (240 000 km), whichever occurs
first, if you add only DEX-COOL
®
extended
life coolant.
The following explains your cooling system and
how to add coolant when it is low. If you have
a problem with engine overheating, see Engine
Overheating on page 478.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®
coolant will:
•
Give freezing protection down to
−
34°F (
−
37°C).
•
Give boiling protection up to 265°F (129°C).
•
Protect against rust and corrosion.
•
Help keep the proper engine temperature.
•
Let the warning lights and gages work as
they should.
Notice: Using coolant other than DEX-COOL
®
may cause premature engine, heater core,
or radiator corrosion. In addition, the engine
coolant may require changing sooner, at
the first maintenance service after each
30,000 miles (50 000 km) or 24 months,
whichever occurs first. Any repairs would not
be covered by your warranty. Always use
DEX-COOL
®
(silicate-free) coolant in your
vehicle.
