When to Check and What to Use

How to Check and Add Fluid

You do not need to check the fluid level unless you
suspect a clutch problem. To check the fluid level, take
the cap off. If the fluid reaches the step inside the
reservoir, the fluid level is correct. See Engine
Compartment Overview on page 5-12 for more
information on location.

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 5 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 5-23.
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.
