Cooling System
When you decide it’s safe to lift the hood, here’s what
you’ll see:
An electric engine cooling fan under the hood can
start up even when the engine
is not running and
can injure you. Keep hands, clothing and tools
away from any underhood electric fan.
If the coolant inside the coolant recovery tank is boiling,
don’t do anything else until
it cools down.

How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at the COLD mark, add a
50/50 mixture of clean
water (preferably distilled) and DEX-COOL@ engine
coolant at the coolant recovery tank. (See “Engine
Coolant” in the Index for more information.)
A CAUTION:
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 mixture will. Your vehicle’s coolant
warning system is set for the proper coolant
mixture. With plain water or the wrong mixture,
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 mixture of clean water and
DEX-COOL@ coolant.
I NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mixture.

I A CAUTION:
Never use oil or grease on studs or nuts. If you
do, the nuts might come loose. Your wheel could
fall off, causing
a serious accident.
Replace the wheel nuts
with the rounded end
of
the nuts toward the
wheel. Tighten each nut
by hand until the wheel
is held against the hub.
9. Lower the vehicle by turning the jack handle to the
left. Lower the jack completely.

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.
1 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 not
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).

Filling a Portable Fuel Container Checking Things
Under the Hood
Never fill a portable fuel container while it is in
your vehicle. Static electricity discharge from the
container can ignite the gasoline vapor. You can
be badly burned and your vehicle damaged
if this
occurs. To help avoid injury to you and others:
0 Dispense gasoline only into approved
containers.
0 Do not fill a container while it is inside a
vehicle, in a vehicle's trunk, pickup bed or
on any surface other than the ground.
inside of the fill opening before operating
the nozzle. Contact should be maintained
until the filling is complete.
0 Bring the fill nozzle in contact with the
Don't smoke while pumping gasoline. An
electric fan under the hood can start up and
injure you even when the engine
is not running.
Keep hands, clothing and tools away from any
underhood electric fan.

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.
3800 Supercharged (Code 1) Engine
(If Equipped)
Your vehicle may have a 3800 Supercharged engine.
The supercharger is a device which is designed to pump
more air into the engine than it would normally use.
This
air is mixed with fuel, which creates increased
engine power. Since the supercharger is a pump and is
driven from an engine accessory drive belt, increased
pressure
is available at all driving conditions.
The Powertrain Control Module (PCM), works with a
vacuum control to regulate the increased pressure
required during specific driving conditions. When this
increased pressure or boost is not desired, such as during
idling and light throttle cruising, the excess air that the
supercharger is pumping is routed through a bypass. All
of these controls working together provide high
performance character and fuel efficiency in the
3800
Supercharged L67 engine.
Engine Oil
LOW
OIL
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
Level Light” in the Index.
You should check your engine oil level regularly; this
is
an added reminder.
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.

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.
The engine oil dipstick handle is the yellow loop near
the front
of the engine.
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.
