All Cooling Systems
A CAUTION:
Adding only plain water to your c.ooling 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 a proper
antifreeze.

I
A CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene
glycol
and it will burn if the engine parts are hot
enough. Don't spill coolant on
a hot engine. I

Gasolines for Cleaner Air
Your use of gasoline with detergent additives will help
prevent deposits
from forming in your engine and fuel
system. That helps keep your engine in tune and your
emission control system working properly. It’s good for
your vehicle, and you’ll be doing your part for cleaner
air.
Many gasolines
are now blended with materials called
oxygenates. General Motors recommends that you use gasolines
with these blending materials, such as MTBE
and ethanol.
By doing so, you can help clean the air,
especially
in those parts of the country that have high
carbon monoxide levels.
In addition, some gasoline suppliers are now producing
reformulated gasolines. These gasolines are specially
designed to reduce vehicle emissions. General Motors recommends that you use reformulated gasoline. By
doing
so, you can help clean the air, especially in those
parts of the country that have high ozone levels.
You should ask your service station operators if their
gasolines contain detergents and oxygenates, and if they
have been reformulated to reduce vehicle emissions.
F’uels in Foreign Countries
If you plan on driving in another country outside the U.S.
or Canada, unleaded fuel may be hard to find.
Do not use leaded gasoline. If you use even one tankful,
your emission controls won’t work well or at
all. With
continuous use, spark plugs can get fouled, the exhaust
system can corrode, and your engine oil can deteriorate
quickly. Your vehicle’s oxygen sensor will be damaged.
All of that
means costly repairs that 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) .

/i CAUTION:
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 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
properly. Then just pull the hood down and close it
firmly.
Engine Oil
I‘
I
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. The
3300 V6 engine oil dipstick is located near the front and
center
of the engine compartment.
ProCarManuals.com

The 2.2L LA engine oil dipstick is located in the fill cap
near the front and center of the engine compartment.
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.
To Check Engine Oil: Pull out the dipstick and dean it
with a paper towel or cloth, then push it back in
all the
way. Remove it again, keeping the tip lower.
When to Add Oil: If the oil is at or below the “ADD”
line, then you’ll need to add some oil. But you must use
the right kind. This section explains what kind of
oil to
use. For crankcase capacity, see “Capacities and Specifications”
in the Index.

ProCarManuals.com

Just fd it enough to put the level somewhere in the
proper operating range. Push the dipstick all the way
back in when you’re through.
What Kind of Oil to Use
Look for three things:
SG
“SG”
must be on the oil container, either by itself or
combined with other quality designations, such as
“SG/CC:’ “SG/CD:’ “SF, SG, CC:’ etc. These letters
show American Petroleum Institute
(API) levels of quality.
