How to Check and Add Fluid
To check the ¯uid level, look at the markings on the
reservoir. If the ¯uid level is between the MIN and the
MAX line, the ¯uid level is correct. If the ¯uid level
is between these marks do not remove the cap, as the
¯uid will quickly absorb moisture. See
Engine
Compartment Overview on page 5-12for more
information on reservoir location.
If ¯uid does need to be added, ®rst turn the vehicle off.
Remove the cap and add the proper ¯uid. Remember
to replace the cap and clean up any spilled ¯uid.
Engine Coolant
The cooling system in your vehicle is ®lled with
DEX-COOLžengine coolant. This coolant is designed
to remain in the vehicle for ®ve years or 150,000 miles
(240 000 km), whichever occurs ®rst, if only
DEX-COOL
žextended life coolant is added.The following explains the cooling system and how to
add coolant when it is low. If there is a problem
with engine overheating or if coolant needs to be added
to the radiator, see
Engine Overheating on page 5-26.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
žcoolant will:
·Give freezing protection down to-34ÉF (-37ÉC).
·Give boiling protection up to 265ÉF (129ÉC).
·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-COOLžmay
cause premature engine, heater core, or radiator
corrosion. In addition, the engine coolant may
require changing sooner, at the ®rst maintenance
service after each 30,000 miles (50 000 km) or
24 months, whichever occurs ®rst. Any repairs
would not be covered by your warranty. Always use
DEX-COOL
ž(silicate-free) coolant in your vehicle.
