kind
.of ail you have, and some other things. Instead of
trying to list everything here, we ask that you contact

“Scheduled Maintenance S-ervic-es” in the Index.
HOW to Check Lubricant
If the 1ev.el is below -the bottom of the filler plug hole,
youfll need to add some lubricant.
If the differential is at aperating temperature (warm),
add enough lubricant to ,raise the level to the bottom of
the filler plug hole,
If the differe.ntia1 is. cold, add enough lubricant to raise-
the level
to 1/2 inch ( 12 mm) below the filler plug hole.
What to Use
Refer to the Maintenance Schedule to determirie what
kind
of lubricant to use. See “Recommended Fluids and
Lubricants” in the Index.
Engine C,oolant
The cooling system in your vehicle is filled
with
DEX-COOL@ engine coolant. This coolant is
designed to remain in your vehicle for:5 year$ or
150,000 miles (240 000 km), whicheveroccurs first,
if you add only DEX-COOL@ extended life coolant.
The fdIowing explains

your vehicle will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to-265'0F (129 "C).
0 Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the whg lights and gages work as they should.
NOTICE:
When adding. coolant, It is important that you use
only DEX--COOL@ (s&ate-&ee) coolant.
Tf co.olant 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 sdoner

30,000 miles (SO 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.
W.hat to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half
DEX-COOL' coolant which
won't
damage aluminum parts. If YOU use this mixture,
you don't need
to add anything else.
Adding only plain water to your co ng system
can be dangerous.
Plain water, or some other
Iiquid.like alcohol, can boil before the proper
coolant mix will. Your vehicle's coolant warning
system is set
for the proper coolant mix. With
plain water or the wrong mix, your engme could
get too hot but you wouldn't get the overheat
warning. Your engme

NOTICE:
Your radiator cap is a 15 psi (105 kPa)
pressure-type cap and must be tightly installed to
prevent coolant loss and possible engine damage
from overheating. Be sure the arrows on the cap
line
up with the overflow tub.e on the radiator
filler neck.
Engine coolant temperature is controlled by a thermostat
in the engine
coolant sys-tem. The. thermostat stops the
flow of coolant through the radiator until the coolant
reaches a preset temperature.
