You can be injured and your vehicle could be
damaged if you try to
do service work on a
vehicle without knowing enough about it.
Be sure you have sufficient knowledge,
experience, the proper replacement parts
and tools before you attempt any vehicle
maintenance task.
Be sure to use the proper nuts, bolts and
other fasteners. “English” and (‘metric”
fasteners can be easily confused.
If you use
the wrong fasteners, parts can later break
or fall off. You could be hurt.
Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the airflow around it. This may cause wind noise
and affect windshield washer performance. Check with
your Pontiac dealer before adding equipment
to the
outside
of your vehicle.
Fuel
The 8th digit of your vehicle identification number
(VIN) shows the code letter for your engine. You will
find the
VIN at the. top left of your instrument panel.
(See “Vehicle Identification Number” in the Index.)
If you have the 3800 engine (VIN Code K), use regular
unleaded gasoline rated at
87 octane or higher.
If you have the 5.7L engine (VIN Code I?), use premium
unleaded gasoline rated at
91 octane or higher for best
performance. You may use middle grade or regular
unleaded gasolines, but your vehicle may not accelerate
as well.

At a minimum, the gasoline you use should meet
specifications
ASTM D4814 in the United States and
CGSB 3.5-M93 in Canada. Improved gasoline
specifications have been developed by the American
Automobile Manufacturers Association
(AAMA) for
better vehicle performance and engine protection.
Gasolines meeting the AAMA specification could
provide improved driveability and emission control
system protection compared to other gasolines,
Be sure the posted octane for premium is at least
91 (at least 89 for middle grade and 87 for regular).
If the octane is less than
87, you may get a heavy
knocking noise when
you drive. If it’s bad enough,
it can damage your engine.
If you’re using fuel rated at the recommended octane
or higher and you still hear heavy knocking, your
engine needs service.
But dm9t worry if you hear a little
pinging noise when you’re accelerating
or driving up a
hill. That’s normal, and you don’t have
to buy a higher
octane fuel
to get rid of pinging. It’s the heavy, constant
knock that means you have
a problem. If
your vehicle is certified
to meet California Emission
Standards (indicated on the underhood tune-up label), it
is designed to operate on fuels that meet California
specifications. If such fuels are
not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily
on fuels meeting federal
specifications, b’ut emission control system performance
may be affected. The malfunction indicator lamp
on
your instrument panel may turn on and/or your vehicle
may fail
a smog-check test. If this occurs, return to your
authorized Pontiac dealer for diagnosis to determine
the
cause of failure. In the event it is determined that the
cause of the condition is the type of fuels used, repairs
may not be covered by your warranty.
Some gasolines that
are not reformulated for low
emissions contain
an sctane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl (MMT);
ask your service station operator whether or not his fuel
contains
MMT. General Motors does not recommend the
use of such gasolines. If fuels containing MMT are used,
spark plug life may be reduced and your emission
control system performance may
be affected. The
malfunction indicator lamp on your instrument panel
may turn
on. If this occurs, return to your authorized
Pontiac dealer for service.

To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent deposits from forming in your engine and fuel
system, allowing your emission control system to
function properly. Therefore, you should not have to add
anything to the fuel. In addition, gasolines containing
oxygenates, such
as ethers and ethanol, and
reformulated gasolines may be available in your area to
help clean the air. General Motors recommends that you
use these gasolines if they comply with the
specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don’t use it. It can corrode
metal parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn’t
be covered under your warranty.
Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard to
find. Never use leaded gasoline or any other fuel n’ot
recommended in the previous text on fuel. Costly repairs
caused by use of improper fuel wouldn’t be covered by
your warranty.
To check on fuel availability, ask an auto club, or
contact a major oil company that does business in the
country where you’ll be driving.
You can also write us at the following address for
advice. Just tell us where you’re going and give your
Vehicle Identification Number (VIN).

When you put the cap back on, turn it to the right
(clockwise) until you hear a clicking sound. Make
sure you fully install the cap. The diagnostic system
can determine
if the fuel cap has been left off or
improperly installed. This would allow fuel to
evaporate into the atmosphere. See “Malfunction
Indicator
Lamp” in the Index.
1~ NOTICE: I
If you need a new cap, be sure to get the right
type. Your dealer can get one for you. If you get
the wrong type, it may not fit or have proper
venting, and your fuel tank and emissions
system
might be damaged.
Checkinr Things Under the Hood
An electric fan under the hood can start up and
injure
you even when the engine is not running, i
Keep hands, clothing and tools away from any
underhood electric fan.
Things that burn can get on hot
engine parts a:
start
a fire. These include liquids like gasoline,
oil,
coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber.
You or others
could be burned. Be careful not to
drop or spill
things that will burn onto a hot engine.

Before closing the hood, be sure all the filler caps
are on.
Then just pull the hood down and close it firmly.
Engine Oil
LOW
It’s a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
Th,e engine
oil dipstick is the yellow loop near the back
of the engine.
If the LOW OIL light on the instrument panel comes on,
it means you need to check your engine oil level right
away.
For more information, see “Low Oil Light” in the
Index. You should check your engine oil level regularly;
this is an added reminder.
5.7L Engine Oil Dipstick
6- 12

3800 Engine
3800 L36 (Code K) Oil Dipstick
Turn off the engine and give the oil a few minutes to
drain back into the oil pan.
If you don’t, the oil dipstick
might not show
the actual level.
Checking Engine Oil
Pull out the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it again,
keeping the tip down, and check the level.
5.7L Engine

1 Vf a I IJ
If you have the 5.7L LT1 engine (with the WS6 option),
your air cleaner will be located over the radiator near the
front
of the engine.
To remove the filter, remove the screws (located on the
rear edge of the air cleaner), lift the air cleaner and
remove
the filter.
Automatic Transmission Fluid
When to Check and Change
A good time to check your automatic transmission fluid
level is when the engine oil is changed.
Change both the fluid and filter every 15,000 miles
(25 000 km) if the vehicle is mainly driven under one
or more of these conditions:
In heavy city traffic where the outside temperature
0 In hilly or mountainous terrain.
regularly reaches
90” F (32” C) or higher.
0 Uses such as high
performance operation.
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, change the fluid and filter every
100,000 miles ( 166 000 km),
See “Scheduled Maintenance Services” in the Index.
