DO NOT USE SAE 2OW-50 OR ANY OTHER
GRADE OIL NOT RECOMMENDED
As shown in the chart, if you have the 3.4L engine,
SAE 1OW-30 is best for your vehicle. However, you can
use
SAE 5w-30 if it’s going to be colder than 60°F
( 16 O C) before your next oil change. When it’s very cold,
you should use
SAE 5W-30. These numbers on an oil
container show its viscosity, or thickness.
Do not use
other viscosity oils, such as SAE 20W-50.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline
Engines
“Starburst” symbol. Failure to use the
recommended oil
can result in engine damage
not covered by

Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving
in stop-and-go traffic).
Most trips are through dusty areas.
You frequently tow a trailer or use a carrler on top of
your vehicle.
The vehicle is used for delivery service, police, taxi
or other commercial application.

Driving under these conditions causes engine oil to
break down sooner. If any one of these is true for your
vehicle, then you need to change your oil and filter
every
3,000 miles (5 000 km) or 3 months -- whichever
occurs first.
If none of them
is true, change the oil and filter every
7,5080 miles (12 500 km) or 12 months -- whichever
occurs first. Driving a vehicle with a fully warmed
engige mder highway conditions causes engine oil to
break down slower.
What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may
be unhealthy for your skin and could
even cause cancer? Don't let used oil stay on .your skin
for very long. Clean your skin and nails with soap and
water, or'a good hand cleaner. Wash or properly throw
away clothing or rags containing used engine oil. (See
the manufacturer's warnings about the use and disposal
of oil products.)
.;4;-". ; ' '*?-
Used oil can be a real threat to the environment. If you
change your own oil, be sure to drain all free-flowing oil.
from the filter before disposal. Don't ever dispose of oil
by putting it in the trash, pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle
it by taking it to a place that collects used oil. Lf
you have a problem properly disposing of your used oil,
ask your dealer, a service station or
a local recycling
center for help.

Air Cleaner
To check or replace the air filter, remove the four screws
and pall off the cover. Pull
out the filter.
Be sure to install the air filter and
install the cover tightly when you are finished.
Refer to the Maintenance Schedule to determine when to
replace the air filter.
See “Scheduled Maintenance Services”
in the Index.
ProCarManuals.com

Operating the engine with the air cleaner off can
cause you or others to
be burned. The air cleaner
not only cleans the air, it stops flame if the,engine
backfires.
If it isn’t there, and the engine
backfires, you could be burned. Don’t drive with
it
off, and be careful working on the engine with
the air cleaner off.
I NOTICE:
If the air cleaner is off, a backfire can cause a
damaging engine fire. And, dirt can easily get
into your engine, which will damage it. Always
have the air cleaner in place when you’re driving.
Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle fluid
level is when the engine oil is changed.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of these conditions:
0 In heavy city traffic where the outside temperature
0 In hilly or mountainous terrain.
regularly reaches
90°F (32” C) or higher.
0 When doing
frequent trailer towing.
Uses such as found in taxi, police or delivery service.
If
YOU do not use your vehicle under any of these
conditions, the fluid
and filter do not require changing.
See “Scheduled Maintenance Services” in the Index.
ProCarManuals.com

Because this operation can be a little difficult, you
may choose
to have this done at your Pontiac dealership
Service Department.
If you do it yourself, be sure to follow all the instructions
here,
or you could get a false reading on the dipstick.
Too much or too little fluid can damage your
transaxle,
Too much can mean that some of the
fluid could come out and fall on hot engine parts
or exhaust system parts, starting a fire.
Be sure to
get an accurate reading if you check your
transaxle fluid.
Wait at least 30 minutes before checking the transaxle
fluid level if you have been driving:
When outside temperatures are above 90°F (32" C).
At high speed for quite a while.
In heavy traffic -- especially in hot weather.
0 While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which is
180°F to 200°F
(82°C to 93°C).
Get the vehicle warmed up by driving about
15 miles
(24 km) when outside temperatures are above 50°F
(10°C). If it's colder than 50°F (lO°C), you may have
to drive longer.

How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transaxle fluid to use. See “Recommended
Fluids
and Lubricants” in the Index.
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.

Engine Coolant
The cooling system in your vehicle is filled with new
DEX-COOL (orange-colored, silicate-free) engine
coolant. This coolant is designed
to remain in your
vehicle for 5 years or 100,000 miles (166 000 km), ,
whichever occurs first.
The following explains your cooling system and how to
add coolant when it is low.
If you have a problem with
engine overheating or
if you need to add coolant to your
radiator, see “Engine Overheating” in the Index.

Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265 “F (129°C).

Let the warning lights lights and gages work as
they should.
ProCarManuals.com

NOTICE:
When adding coolant it is important that you use
DEX-COOL
TM (orange-colored, silicate-free)
coolant meeting
GM Specification 6277M.
If silicated coolant 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.
What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half DEX-COOL
TM (orange-colored,
silicate-free) antifreeze that meets GM Specification
6277M, which won’t damage aluminum
parts. Use
GM Engine Coolant Supplement (sealer) (GM Part
No. 3634621) with any complete coolant change. If you
use this mixture, you don’t need. to add anything else.
Adding only plain water to your cooling system
can be dangerous. 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 overheat
warning. Your engine could catch fire and you or
others could be burned.
Use a 50/50 mix of clean
water and DEX-COOL
TM (orange-colored,
silicate-free) antifreeze.

NOTICE:
If yos we 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 engine, radiator, heater core and
other parts.
If you have to add coolant more than four times a year,
have your dealer check
your cooling system.
I NOTICE:
If you use the proper coolant, you don’t have to
add extra inhibitors or additives which claim to
improve the system. These can’ be harmful.
Checking Coolant
When your engine is cold, the coolant level should be at
the
COLD mqk or a little higher. When your engine is
warm, the level should be up to the HOT mark or a
little higher.
