Oils with these words on the container will help you save fuel.
This doughnut-shaped logo (symbol) is used
on most oil containers to help
you select the correct oil.
You should look for this on the oil container, and use
only those oils that
display the logo.
GM Goodwrench@ oil (in Canada, GM Engine Oil) meets all the requirements
for your vehicle.
Engine Oil Additives:
Don’t add anything to your oil. Your GM dealer is ready to advise if you think
something should be added.
When to Change Engine c)k
See if any one of these is true for you:
Most trips are less than 4 miles (6 km).
It’s below freezing outside and most trips are less than 10 miles
(16 km).
The engine is at low speed most of the time (as in door-to-door delivery,
You tow a trailer often.
or in stop-and-go traffic).
Most trips are through dusty places.
The vehicle is frequently operated off-road.
If any one of these is true for your vehicle, you need to chang\
e your oil and
filter every 3,000 miles (5000 km) or 3 months-whichever comes first.
If none of them are true, change the oil every 7,500 miles (12 500 km) or
12 months-whichever comes first. Change the filter at the first oil change
and at every other oil change after that.
If your vehicle has 4-wheel drive, you ,will have a remote oil filter located
under the hood.
It is mounted to the front left inner fender, behind the
headlights.
Engine Block Heater:
An engine block heater can be a big help if you have to park outside in very
cold weather,
-0°F (-18°C) or colder. If your vehicle has this option, see
“Engine Block Heater” in the Index.

What to Do with Used Oil:
I A Used engine oil contains things that have caused skin cancer in
- laboratory animals. 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
I used engine oil. I
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.
If you have a problem disposing of your used oil, ask
your dealer, a service station
or a local recycling center for help.

and change the filter. Care should be taken during reassembly to ensure that
the cover is on straight and the wingnut properly tightened.
To remove the square air cleaner filter for the 4.3L (VIN W) high performance

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. Refer to the Maintenance Schedule to de\
termine when
to change your fluid. See “Scheduled Maintenance Services” \
in the Index.
How to Check:
Because this operation can be a little difficult, you may choo\
se to have this
done at a 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.
I NOTICE
Wait at least 30 minutes before checking the transmission 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.
While pulling a trailer.
To get the right reading, the fluid must be at normal operating \
temperature,
which is 180°F to 200°F (82°C to 93°C).
To check transmission fluid hot: 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 then 50°F (IO’C), drive the vehicle in D (3rd gear) until the
temperature gage moves and then remains steady for ten minutes.\
Then
follow the hot check procedures.
To check transmission fluid cold: A cold check is made after the vehicle
has been sitting for eight hours or more with the engine off and is used
only
as a reference. Let the engine run at idle for five minutes if outside
temperatures are
50°F (10°C) or more. If it’s colder than 50°F (lO°C), you
may have to idle the engine longer. A hot check must follow when fluid is
added during a cold check.

Downloaded from www.Manualslib.com manuals search engine To check the fluid hot or cold:
Park your vehicle on a level place.
Place the shift lever in P (Park) with the parking brake applied.
With your foot on the brake pedal, move the shift lever through each
gear range, pausing for about three seconds in each range. Then,
position the shift lever in
P (Park).
Let the engine run at idle for three minutes or more.
Then, without shutting
off the engine, follow these steps:

If you have a 4.3L engine, you will have a flip-top handle. Flip\
the
handle up and then pull out the dipstick and wipe it clean with a rag or
paper towel.
2. Push it back in all the way, wait three seconds and then pull it back out
again. Flip top handle should remain in open position.

3. Check both sides of the dipstick, and read the lower level. The fluid
level must be in the COLD area for a cold check or in the HOT area or
cross-hatched area for a hot check.
4.
If the fluid. level is where it should be, push the dipstick bac\
k in all the
way.
If you have a flip-top handle, flip the handle down to lock it in place.
How To Add Fluid:
Refer to the Maintenance Schedule to determine what kind of transmission
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
up to the COLD area for a cold check or the HOT area for a hot c\
heck. It
doesn’t take much fluid, generally less than a pint. Don’\
t overfill. We
recommend you use only fluid labeled DEXRON@lIE, because fluids \
with that
label are made especially for your automatic transmission. Damag\
e caused by
fluid other than DEXRON@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 ba\
ck in all the
way. Flip the handle down
if you have a flip-top handle.
