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 level reaches the top of the
reservoir, the fluid level is correct. It isn’t a good idea to
top off your clutch fluid. Adding fluid won’t correct a
leak. A fluid loss in this system could indicate a
problem. Have the system inspected and repaired.
Engine Coolant
The cooling system in your vehicle is filled with
DEX
-COOL
R
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
R
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” in
the Index.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
R
coolant will:
D
Give freezing protection down to
-34
_
F (-37
_
C).
D
Give boiling protection up to 265
_
F (129
_
C).
D
Protect against rust and corrosion.
D
Help keep the proper engine temperature.
D
Let the warning lights and gages work as
they should.
NOTICE:
When adding coolant, it is important that you
use only DEX
-COOL
R
(silicate-free) coolant.
If coolant other than DEX-COOL is added to
the system, premature engine, heater core or
radiator corrosion may result. In addition, the
engine coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first. Damage caused by the
use of coolant other than DEX
-COOL
R
is not
covered by your new vehicle warranty.
