When to Check and What to Use
The hydraulic clutch fluid
reservoir cap has this
symbol on it. See
Engine
Compartment Overview
on page 5-12 for reservoir
location.
Refer to the Maintenance Schedule to determine how
often you should check the fluid level in your clutch
master cylinder reservoir and for the proper fluid to use.
See
Owner Checks and Services on page 6-9 and
Recommended Fluids and Lubricants on page 6-13.
How to Check and Add Fluid
Make sure the fluid level is at the MIN line on the side
of the reservoir. If it is not, remove the cap and add
the proper fluid until the level reaches the MIN line.
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 5-29.
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 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.
