Engine Overheating
You will find a coolant temperature gage on your
Aurora’s instrunlent panel. Your information center
will
also display messages about engine overheating. See
“Coolant Temperature Gage“
in the Index.
Overheated Engine Protection Operating Mode
Should a low coolant condition exist and the message
HOT STOP ENGINE display, an overheat protection
mode which alternates firing groups of four cylinders
helps prevent engine damage. This operating mode
allows
YOLIP vehicle to be driven to a safe place in an
emergency; you may drive
up to 50 miles (80 km).
Towing a trailer in the overheat protection lnode should
be avoided.
NOTICE:
After driving in the “Overheated Engine
Protection Operating Mode,” to avoid engine
damage, allow the engine to cool before
attempting any repair. The engine oil may be
severely degraded. Change the oil and reset the
oil life indicator. See “Engine Oil, When to
Change” in the Index.
If Steam Is Coming From Your Engine

NOTICE:
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. See “Overheated
Engine Protection Operating Mode” in the Index.
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:
Climb a long hill on a hot day.
Stop after high speed driving.
Idle for long periods in traffic.
Tow a trailer.
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 (@) or THIRD (3).
If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about
10 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,
turf? ofthe engine and get everyone out qf the
vehicle until it cools down. Also, see “Overheated
Engine Protection Operating Mode” listed previously
in
this section.
You may decide not to lift the hood but to get service
help right away.

Engine Accessory Belt
The 4.0L Aurora engine uses an engine accessory belt.
This diagram shows the features connected by the belt
routing. See”Maintenance Schedu1e”in the Index for
when to check the belt.
1. Tensioner Arm Pulley
2. Power Steering Pump Pulley
3. Idler Pulley 4.
Alternator Pulley
5. Air Conditioner Compressor Pulley
6. Harmonic Balancer
Engine Oil
If the CHECK 01L LEVEL message or the oil warning
light on the instrument panel comes
on, it means you
need to check your engine oil level right away.
For more
information, see “Check Oil Level Message” or
“Oil
Warning 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.
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.

Brake Wear
Your Aurora has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that make
a high-pitched warning sound when the brake pads are
worn and new pads are needed. The sound may come
and
go or be heard all the time your vehicle is moving
(except when
you are pushing on the brake pedal
firmly).
I NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something is wrong
with
your brakes.
Brake linings should always
be replaced as complete
axle sets.
Brake Pedal Travel
See your retailer if the brake pedal does not return to
normal height, or
if there is a rapid increase in pedal
travel. This could be
a sign of brake trouble.
Brake Adjustment
Every time YOLI apply the brakes, with or without the
vehicle moving, your brakes adjust for wear.

Wheel Replacement
Replace any wheel that is bent, cracked, or badly rusted
or corroded. If wheel nuts keep coming loose, the wheel,
wheel bolts, and wheel nuts should be replaced.
If the
wheel leaks air, replace it (except some aluminum
wheels, which can sometimes
be repaired). See your
Aurora retailer if any
of these conditions exist.
Your retailer will know the kind
of wheel you need.
Each new wheel should have the same load carrying
capacity, diameter, width, offset, and be mounted the
same way as the one it replaces.
If you need
to replace any of your wheels, wheel bolts,
or wheel nuts, replace them only with new
GM original
equipment parts. This way, you will be sure to have the
right wheel, wheel bolts, and wheel nuts for your Aurora
model.
I NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling,
speedometer/odometer calibration, headlamp aim, bumper height, vehicle ground clearance,
and tire
or tire chain clearance to the body and
chassis.

Tires
To clean your tires, use a stiff brush with a tire cleaner.
When applying a tire dressing always take care
to wipe
off any overspray or splash from painted surfaces.
Petroleum-based products may damage the paint finish.
Sheet Metal Damage
If your vehicle is damaged and requires sheet metal
repair or replacement, make sure the body repair shop
applies anti-corrosion material
to the parts repaired or
replaced to restore corrosion protection.
Finish Damage
Any stone chips, fractures or deep scratches in the finish
should be repaired right away. Bare metal
will corrode
quickly and may develop into a major repair expense.
Minor chips and scratches can be repaired with touch-up
materials available from your retailer or other service
outlets. Larger areas
of finish damage can be corrected
in your retailer’s body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow removal and dust
control can collect
on the underbody. If these are not removed,
accelerated corrosion (rust) can occur on the
underbody parts such as fuel lines, frame, floor pan, and
exhaust system even though they have corrosion
protection.
At least every spring,
flush these materials from the
underbody
with plain water. Clean any areas where mud
and other debris can collect. Dirt packed
in closed areas
of the frame should be loosened before being flushed.
Your retailer or an underbody vehicle washing system
can do this for you.
Chemical Paint Spotting
Some weather and atmospheric conditions can create a
chemical fallout. Airborne pollutants can fall upon and
attack painted surfaces on your vehicle. This damage
can take two forms: blotchy, ringlet-shaped
discolorations, and small irregular dark spots etched into
the paint surface.
Although no defect
in the paint job causes this,
Oldsmobile will repair, at no charge to the owner, the
surfaces of new vehicles damaged by this fallout
condition
within 12 months or 12,000 miles (20 000 km)
of purchase, whichever comes first.
