1997 CHEVROLET CORVETTE oil temperature

Downloaded from www.Manualslib.com manuals search engine Engine Overheating
You will find an engine coolant temperature gage on the
instrument cluster and a COOLANT OVER TEMP
message on the Driver Information Center.
Overheated Engine Protection
Operating
Mode
Should a low coolant condition exist and the messages
COOLANT OVERTEMP and REDUCED ENGINE
POWER
are displayed, along with the CHECK
ENGINE light, an overheat protection mode which alternates firing groups of four cylinders helps prevent
engine damage. In this mode, you will notice a loss in
power and engine performance. This operating mode allows your vehicle to be driven to a safe place in an
emergency; you may drive up to
50 miles (80 km).
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 will be severely degraded. Repair
the cause of coolant
loss, change the oil and reset
the oil life monitor. See “Engine Oil, When to
Change” in the Index.

SAE 5W-30
As shown in the viscosity chart, SAE 5W-30 is best
for your vehicle. However, you can use
SAE
1OW-30 if it’s going to be 0°F (-18°C) or above.
These numbers on an oil container show its viscosity,
or thickness.
Do not use other viscosity oils such as
SAE 20W-50.
Oils meeting these
requirements should also
have the “Starburst” symbol
on the container.
This symbol indicates that the oil has been certified by
the American Petroleum Institute
(API). Do not use any
oil which does not carry this Starburst symbol.
You should look for this on the oil container, and use
only those oils that are identified as meeting GM
Standard
47 18M and have the Starburst symbol on the
front
of the oil container.

Downloaded from www.Manualslib.com manuals search engine Your Corvette engine is filled at the factory with a
Mobil
l@ synthetic oil, which meets all requirements for
your vehicle.
Substitute 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°F
(- 18 O C), you may
substitute SAE 1OW-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 Chevrolet 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 (1 6 000 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
(1 6 000 km) or 12 months
(whichever occurs first) without an oil change. Use
engine oil meeting the GM Standard GM4718M. 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 km) 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 Chevrolet 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 on the DIC 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 Change both the fluid and filter every 50,000 miles
(80 000 km) if the vehicle is mainly driven under one of
these conditions:
In heavy city traffic where the outside temperature
regularly reaches
90” F (32” C) or higher.
In hilly or mountainous terrain.
0 High performance operation.
If you do not use your vehicle under one of these
conditions, the fluid and filter do not require changing.
See “Scheduled Maintenance Services” in the Index for
the proper service intervals for the transmission fluid
and filter.
Manual Transmission Fluid
When to Check
A good time to have it checked is when the engine oil is
changed. However, the fluid in your manual
transmission doesn’t require changing.
How to Check
Because this operation can be difficult, you may
choose to have this done at your Chevrolet dealership
Service Department.
If you do it yourself, be sure to follow all the
instructions here, or you could get a false reading.
I NOTICE:
Too much or too little fluid can damage your
transmission.
Too much can mean that some
of the fluid could come out and fall on hot
exhaust system parts, starting a fire. Be sure to
1 get an accurate reading if you check your
transmission fluid.
Check the fluid level only when your engine is off, the
vehicle is parked on a level place and the transmission is
cool enough for you to rest your fingers
on the
transmission case.

Downloaded from www.Manualslib.com manuals search engine A 50/50 mixture of water and DEX-COOL@
coolant will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265 "F (129" C).
Protect against rust and corrosion.
Help keep the proper engine temperature,
Let the warning lights and gages work as
they should.
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.
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 mix will. Your vehicle's coolant warning
system
is set for the proper coolant mix. With
plain water or the wrong mix, 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 mix of clean
water and DEX-COOL@ coolant.
