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.

What Kind of Oil to Use
Oils of the proper quality for your vehicle can be
identified by looking for the ‘bStarburst” symbol. The
“Starburst” symbol indicates that the oil has been
certified by the American Petroleum Institute (API), and
is preferred for use in your gasoline engine.
If you change your own oil, be sure you use oil that has
the “Starburst” symbol
on the front of the oil container.
If you have your oil changed for you, be sure the oil put
into your engine is American Petroleum Institute
certified
for gasoline engines.
You should also use the proper viscosity oil for your
vehicle, as shown
in the following chart:
RECOMMENDED SAE VlSCOSlTV GRADE ENGINE OILS
FOR BEST FUEL ECONOMY AND COLD STARTING, SELECT THE LOWEST
SAE VISCOSITY GRADE OIL
FOR THE EXPECTED TEMPERATURE RANGE.

As shown in the chart, SAE 10W-30 is best for your
vehicle. However,
you can use SAE SW-30 if it’s going
to be colder than
60°F (16°C) before your next oil
change. When it‘s very cold. you should use
SAE
SW-30. These numbers on an oil container show its
viscosity,
or thickness. Do not use other viscosity oils,
such
X SAE 2OW-SO.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
“Starburst” symbol. Failure to use the proper oil
can result in engine damage not covered by your
warranty.
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 Aurora retailer is
ready
to advise if you think something should be added.
When to Change Engine Oil
See if any one of these is true for you:
0 Most trips are less than 5 to I0 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving
in stop and go traffic).
Most trips are through dusty areas.
0 You frequently tow a trailer or use a carrier on top of
your vehicle.
If any one of-. these is true for your vehicle, then you
need to change your oil and filter every 3,000 miles
(5 000 km) or 3 months -- whichever comes first. (See
“Change Oil Message”
in the Index.) If the CHANGE
OIL NOW message appears in the Driver Information
Center,
you should change your oil.
If none of them is true, change the oil and filter every
7,500 miles
( 12 SO0 km) or 12 months -- whichever
colnes first. (See “Change Oil Message’‘
in the Index.)
Always reset the engine oil life to 100% after every oil
change.

Engine Coolant
The following explains your cooling system and how to
add coolant when
it is low. If you have a problem with
engine overheating, see “Engine Overheating” in the
Index.
The proper coolant for your Aurora will:
0 Give freezing protection down to -34°F (-37°C)
0 Give boiling protection up to 262°F (128°C).
0 Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights work as they should.
What to Use
Use a mixture of one-half c.lt.crr~ wwtor (preferably
distilled) and one-half antifreeze that meets “GM
Specification 182S-M,” which won‘t damage aluminum
parts.
You call also use a recycled coolant conforming to
GM Specification 1825-M
with a complete coolant tlush
and refill. Use GM Engine Coolant Supplement (sealer)
with any cotnplete coolant flush and refill. If you use
this mixture, you don‘t need to add anything else.
A
special procedure is required for adding sealer; see the
ALI~o~~ Service Manual. (To order a service 1nanual. see
