3. Fill the radiator
with the proper
mix,
up to the base
of the filler neck.
If you see a stream of coolant coming from an air
bleed
valve, close the valve. Otherwise, close the
valve(s) after the radiator is filled.
4. Rinse or wipe any spilled coolant nom the engine
and compartment.
5. Then fill the coolant recovery tank to "COLD."
6. Put the cap back on the coolant recovery tank, but

upper radiator hose getting hot. Watch out for the
engine fan(s).
8. By this time the coolant level inside the radiator
filler neck may be lower.
If the level is lower, add
more of the proper mix through the filler neck until
the level reaches the base
of the filler neck.

Things that burn can get on hot engine parts and
start
a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber. You

If the fluid level is low, add only enough of the proper
fluid to bring the level into the cross-hatched area on the
dipstick. It doesn’t take much fluid, generally less than a
pint. Don’t overfill. We recommend you use only fluid
labeled DEXRONB-IIE, because fluids with that label
are made especially for your automatic transaxle.
Damage caused by fluid other than DEXRONB-IIE is
not covered by your new vehicle warranty.
After adding fluid, recheck the fluid level as
described under “How
to Check.”
When the correct fluid level is obtained, push the
dipstick back in all the way.
Engine Coolant
The following explains your cooling system and how to
add coolant when
it is low. If you have a problem with
engine overheat.ing or if you need to add coolant to your
radiator, see “Engine Overheating”
in the Index.
The proper coolant for your Buick will:
0 Give freezing protection down to -34OF (-37OC) .
0 Give boiling protection up to 262 OF (128 “C) .
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights work as they should.
What to Use:
Use a mixture of one-half clean water (preferably
distilled) and one-half antifreeze that meets
“GM
Specification 1825-M,” which won’t damage aluminum
parts. You can also use a recycled coolant conforming to
GM Specification 1825-M with a complete coolant flush
and refill. Use GM Engine Coolant Supplement (sealer)
with any complete coolant change. If you use these, you
don’t need to add anything else.
can be aangerous. Plain water, or some other
liquid 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 engine could
get too hot but you wouldn’t get the overhe-”
warning. Your engine could catch fire and
yuu or
others could be burned. Use a 50/50 mix of clean
water and a proper antifreeze.

NOTICE:
If you use an improper coolant mix, your engine
could overheat and be badly damaged. The
repair cost wouldn’t be covered by
your
warranty. Too much water in the mix can freeze
and crack the enqine, radiator, heater
core and
other parts.

Adding Coolant
The 3.1 liter engine has the coolant recovery tank
located at the
left of the engine Compartment.
__./”
t
The 3.8 liter engine has the coolant recovery tank
located at the left of
the engine compartment.
To Check Coolant: When your engine is cold, the
coolant
level should be at “COLD” or a little higher.
When your engine is warm, the level should
be up to
“HOT,” or a little higher.

If this light comes on, it means you're low on engine
coolant. this light comes
on, it means you're low on
engine coolant (diesel engine only).
To Add Coolant: If you need more coolant, add the
proper mix at the coolant recovery tank.
A CAUTION:
Turning me raalaror pressure cap when the
--1gine and radiator are hot can allow steam ana
scalding liquids to blow out and burn you badly.
With the coolant recovery tank, you will almos'
never have to add coolant at the radiator. Never
turn the radiator pressure cap
-- even a little --
wt- -- +ha engine and radiator are hot.
Add coolant mix at the recovery tank, but be careful not
to spill it.
IU can be burned if you spill coolant on hot
gine parts. Coolant contains ethylene glycol,
and
it will burn if the engine parts are t
enough. Don't spill coolant on a hot engine.

Radiator Pressure Cap rower Steerlng Fluid
1; NOTICE: 1
.:: Your radiator cap is a 15 psi (1 05 kPa)
:: pressure-type cap and must be tightly installed
,*to prevent coolant loss and possible engine
q:. damage from overheating. Be sure the arrows on
,. the cap line up with the overflow tube on the
8: radiator filfer neck.
When you replace your radiator pressure cap, an AC@
cap is recommended.
Thermostat
Engine coolant temperature is controlled by a thermostat
in the engine coolant system. The thermostat stops the
flow of coolant through the radiator until the coolant
reaches a preset temperature.
When you replace your thermostat, an
AC@ thermostat
is recommended.
L
How To Check Power Steering Fluid:
Unscrew the cap and wipe the dipstick with a clean rag.
Replace the cap and completely tighten
it. Then remove
the cap again and look at the fluid level on the dipstick.
0 When the engine compartment is hot, the level
should be at the
“HOT” mark.
0 When the engine compartment is cool, the level
should be at the
“FULL COLD” mark.

Explanation of Scheduled Maintenance
Services
Below are explanations of the services listed in Schedule
I and Schedule 11.
The proper fluids and lubricants to use are listed in
Section D. Make sure whoever services your vehicle uses
these. All parts should be replaced and all necessary
repairs done before
you or anyone else drives the vehicle.
NOTE: To determine your engine’s displacement and
code, see “Engine Identification” in the Index.
1. Engine Oil and Filter Change* -- Always use SG
Energy Conserving I1 oils of proper viscosity. The
“SG” designation may be shown alone or in
combination with others, such as “SG/CC”, ,“SG/CD”
or
“SF, SG, CC,” etc. To determine the preferred
viscosity for your vehicle’s engine (e.g., SAE 5W-30
or SAE 10W-30), see “Engine Oil”
in the Index.
2. Chassis Lubrication -- Lubricate the transaxle shift
linkage, parking brake cable guides, underbody
contact points and linkage. If your vehicle is
equipped with grease fittings, lubricate
the
suspension and steering linkage. 3.
Throttle Body Mounting
Bolt Torque* -- Check
the torque
of the mounting bolts and/or nuts.
4. Tire and Wheel Rotation and Inspection -- For
proper wear and maximum tire life, rotate your tires
following the instructions
in this manual. See “Tires,
Inspection
& Rotation” in the Index. Check the tires
for uneven wear or damage. If you see irregular or
premature wear, check the wheel alignment. Check
for damaged wheels also.
5. Engine Accessory Drive Belt(s) Inspection --
Inspect the belt(s) for cracks, fraying, wear and
proper tension. Replace as needed.
6. Cooling System Service* -- Drain, flush and refill
the system
with new or approved recycled coolant
conforming to GM Specification 1825M. Keep
coolant at the proper mixture as specified. See
“Coolant”
in the Index. This provides proper freeze
protection, corrosion inhibitor level and engine
operating temperature.
Inspect hoses and replace
if they are cracked,
swollen or deteriorated. Tighten screw-type hose
clamps. Clean the outside
of the radiator and air
* An Emission Control Service.
The
U.S. Environmental Protection Agency has determined that the failure to perform this maintenance item will not nullify the emission warranty or limit recall liability prior tothe completion of vehicle useful life. General Motors, however, urges that all recommended maintenance \
services he performed at the indicatcd intervals and the maintenance be recorded in ”Section E:Maintenance Record”.
