1998 CHEVROLET CORVETTE adding oil

Downloaded from www.Manualslib.com manuals search engine Racing or Other Competitive Driving
See your Warranty Book before using your vehicle for
racing
or other competitive driving.
NOTICE:
If you use your vehicle for racing or other
competitive driving, your engine may use more
oil than
it would with normal use. Low oil levels
can damage the engine. Be sure to check the oil
level often during racing or other competitive
driving and keep the level at or near the upper
mark on the engine
oil dipstick. You may need to
add oil. See “Adding Oil” under “Engine” in
the Index.
Engine Coolant Heater
(Canada Only)
The engine coolant heater is located on the driver’s side
of the engine under the manifold. The electrical cord is
attached to the generator bracket assembly, between the
generator and the windshield washer fluid tank.
In very cold weather,
0 OF (- 18 O C) or colder, the engine
coolant heater can help. You’ll get easier starting and
better fuel economy during engine warm-up. Usually,
the coolant heater should be plugged in a minimum of
four hours prior to starting your vehicle.

Downloaded from www.Manualslib.com manuals search engine 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.
NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So
use the recommended coolant.
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.

Downloaded from www.Manualslib.com manuals search engine You should look for this on the oil container, and use
only those oils that are identified as meeting GM
Standard 4718M and have the Starburst symbol on the
front of the oil container.
Your Corvette engine is filled at the factory with a
Mobil
l@ synthetic oil, which meets all requirements
for your vehicle.
Substitute Engine Oil: When adding oil to maintain
engine oil level, oil meeting GM Standard GM4718M
may not be available. You can add substitute oil
designated SAE 5W-30 with the “Starburst” symbol at
all temperatures. If temperatures are above
0 OF (- 18 O C),
you may substitute
SAE low-30 with the “Starburst”
symbol. Substitute oil not meeting GM Standard
GM4718M should not be used for an oil change.
Engine Oil Additives
Don’t add anything to your oil. Your dealer is ready to
advise if you think something should be added.
When to Change Engine Oil
Your Corvette has an Engine Oil Life Monitor. This
feature will let you know when to change your oil and
filter
-- usually between 3,000 miles (5 000 km) and
10,000 miles (16
000 km) since your last oil change. Under severe conditions, the indicator may
come on
before
3,000 miles (5 000 km). Never drive your vehicle
more than 10,000 miles (16
000 km) or 12 months
(whichever occurs first) without an oil change. Use
engine oil meeting the GM Standard GM47 18M.
The system won’t detect dust in the
oil. So, if you drive
in a dusty area, be sure to change your oil every
3,000 miles
(5 000 lun) or sooner if the CHANGE OIL
light comes on. Remember to reset the Engine Oil Life
Monitor when the oil has been changed. For more
.information, see “Engine Oil Life Monitor” in the Index.
When Changing the Engine Oil
There is a special procedure for changing engine oil,
contact your dealer for additional information or the
procedure can be found in a Corvette Service Manual.
To purchase a service manual, see “Service and Owner
Publications” in the Index.
How to Reset the Engine Oil Life Monitor
Press RESET to acknowledge the CHANGE OIL SOON
warning. The oil page will then show a message such as
OIL LIFE
0%. To reset the monitor, press and hold
RESET for two seconds. You will then receive a
message such as OIL LIFE
99%.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
When adding coolant, it is important that you use
only
DEX-COOL@ (silicate-free) coolant.
If coolant other than DEX-COOL is added to the
system, premature engine, heater core or
radiator corrosion may result. In addition, the
engine coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first. Damage caused by the use
of coolant other than DEX-COOL@ is not
covered by your new vehicle warranty.
What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half
DEX-COOL@ coolant which
won’t damage aluminum parts.
If you use this mixture,
you don’t need
to add anything else.
I
/II CALTTION:
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.
