If’ your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would
not be
covered by your warranty.
If No Steam Is Coming From Your Engine
If you get the overheat warning but see or hear no
steam, the problem may not be
too serious. Sometimes
the engine can get a little too hot when you:
0 Climb a long hill on a hot day.
Stop after high speed driving.
0 Idle for long periods in traffic.
If you get the overheat warning with no sign
of steam,
try this for a minute or
so:
1. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (a)
or DRIVE (D) for automatic transmissions.
If you
no longer have the overheat warning, you can drive.
Just to be safe, drive slower for about ten minutes. If the
warning doesn’t come back on, you
can drive normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there’s still no sign of steam, you can idle the engine
for two or three minutes while you’re parked,
to see if
the warning stops. But then, if you still have the
warning,
turn off the engine and get everyone out of the
vehicle
until it cools down.
You may decide not to lift the hood but to get service
help right away.

How to Add Coolant to the Coolant

If you haven’t found a problem yet, but the ,coo,lant level
isn’t at or above the COLD mark, add
a 50MI mixture
of clean water (preferably distilled) and a proper
antifreeze at the coolant recovery tank. (%e “Engine

If a Tire Goes Flat
It’s unusual for a tire to “blow out” while you’re driving,
especially if you maintain your tires properly. If air goes
out of a tire, it’s much more likely to leak out slowly.
But if you should ever have
a “blowout,” here are a few
tips about what to expect and what
to do:
If a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel firmly.
Steer to maintain lane position, then gently brake to a
stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use in a
skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to
go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to a stop, well off the road if possible.
If a tire goes flat, the next part shows how to use your
jacking equipment to change a flat tire safely. If your
vehicle has Extended Mobility Tires (tires with “EMT”
molded on the sidewalls), see “Extended Mobility Tires”
in the Index.

sequence as shown. The
LOWELAT TIRE or SERVICE LTPWS light will
stay on as long as you are using the compact spare tire.
It should go out when the original tire is replaced.
After you have the flat tire repaired or replaced, install
the plastic nut caps and tighten them to
22 pound-inches
(2.5 Nem).
Put the jack, wheel nut socket and wheel lock key in the
rear storage compartment behind
the passenger’s seat.
Make sure the parts are stored properly in the foam
container. Position the jack in the container
so that you
can read the yellow CAUTION label from the driver’s
seat. Replace the plastic tray and close the storage
compartment.

5.7L LT5 (Code J) Engine
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.)
Use premium unleaded gasoline rated at
9 1 octane or
higher. You may use middle grade or regular unleaded
gasolines, but your vehicle may not accelerate as well.
The gasoline you use should meet specifications ASTM
D4814 in the United States and CGSB 3.5-92 in
Canada. These fuels should have the proper additives,
so
you should not have to add anything to the fuel.
In the United States and Canada, it’s easy to be sure you
get the right kind
of gasoline (unleaded). You’ll see
UNLEADED right on
the pump. And only unleaded
nozzles will fit into your vehicle’s filler neck.

Downloaded from www.Manualslib.com manuals search engine Be sure the posted octane is at least 91. If the octane is
less than 91, you may get a heavy knocking noise when
you drive. (In an emergency,
you may be able to use
lower octane
-- as low as 87 -- if heavy knocking does
not occur.)
If you’re using 91 or higher octane unleaded
gas and you still get heavy knocking, your engine needs
service.
What about gasoline with blending materials that
contain oxygen (oxygenates), such as
MTBE or alcohol?
MTBE is “methyl tertiary-butyl ether.” Fuel that is no
more than
15% MTBE is fine for your vehicle.
Ethanol is ethyl or grain alcohol. Properly-blended fuel
that is no more than 10%
ethanol is fine for your
vehicle.
i Wethanol is methyl or wood alcohol.
NOTICE:
Fuel that is more than 5% methanol is bad for
your vehicle. 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. And even at
5% or
less, there must be “cosolvents” and corrosion
preventers in this fuel to help avoid these
problems.

Downloaded from www.Manualslib.com manuals search engine Gasolines for Cleaner Air
Your use of gasoline with deposit control 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 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 deposit control additives and
oxygenates, and if they have been reformulated to
reduce vehicle emissions.
5.7L LT1 (Code P) Engine
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. The gasoline you use should meet
specifications
ASTM D4814 in the United States and
CGSB
3.5-92 in Canada. These fuels should have the
proper additives,
so you should not have to add anything
to the fuel.
In the United States and Canada, it’s easy to be sure you
get the right kind of gasoline (unleaded). You’ll see
UNLEADED right on the pump. And only unleaded
nozzles will fit into your vehicle’s filler neck.
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 91 octane or higher and you
still hear heavy knocking, your engine needs service.
But don’t 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.
