When the differential is cold, add enough lubricant to
raise the level to 1/2 inch (12 mm) below the filler
plug hole.
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.
When the differential is at operating temperature (warm),
add enough lubricant to raise the level to the bottom of the
filler plug hole.
Help keep the proper engine temperature.
What to Use
Let the warning lights and gages work as
they should.
Refer to the Maintenance Schedule to determine what
kind of lubricant to use. See “Recommended Fluids and
Lubricants” in the Index.
NOTICE:
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
When adding coolant, it is important that you
use only DEX-COOL (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
(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”
in the Index.
30,000
miles (50 000 km) or 24 months,
whichever occurs first. Damage caused by the
use of coolant other than DEX-COOL is not
covered by your new vehicle warranty.
