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, look
on the side of the reservoir. If the fluid reaches the
MAX (A) mark on the reservoir, the fluid level is correct.
The reservoir is located near the back of the engine
compartment on the driver’s side of the vehicle.
SeeEngine Compartment Overview on page 5-12for
more information on location.
Engine Coolant
The following explains your cooling system and how to
add coolant when it is low. If you have a problem
with engine overheating, seeEngine Overheating on
page 5-24.
A 50/50 mixture of clean, drinkable water and proper
coolant will:
•Give freezing protection down to−22°F (−30°C).
•Give boiling protection up to 268°F (131°C)
•Protect against rust and corrosion.
•Help keep the proper engine temperature.
•Let the warning lights and gages work as they
should.

What to Use
To determine what kind of fluid to use, seePart D:
Recommended Fluids and Lubricants on page 6-24.
Always use the proper fluid. Failure to use the proper
fluid can cause leaks and damage hoses and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer’s instructions before use. If you will
be operating your vehicle in an area where the
temperature may fall below freezing, use a fluid that has
sufficient protection against freezing.
Adding Washer Fluid
The windshield washer fluid reservoir is located in the
front of the engine compartment on the driver’s side
of the vehicle. SeeEngine Compartment Overview on
page 5-12for reservoir location.Open the cap with the
washer symbol on it.
Add washer fluid until the tank is full.
Notice:
When using concentrated washer uid, follow the
manufacturer’s instructions for adding water.
Do not mix water with ready-to-use washer uid.
Water can cause the solution to freeze and
damage your washer uid tank and other parts of
the washer system. Also, water does not clean as
well as washer uid.
Fill your washer uid tank only three-quarters full
when it is very cold. This allows for expansion if
freezing occurs, which could damage the tank if
it is completely full.
Do not use engine coolant (antifreeze) in your
windshield washer. It can damage your washer
system and paint.
