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
® 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 5-26.
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.
