1995 CHEVROLET CORVETTE coolant temperature

Downloaded from www.Manualslib.com manuals search engine Temperature Sensors
Sunload:
This sensor is on top of the instrument panel.
When the inside temperature
is increased by sunlight,
the system will lower the inside temperature up to
5°F
(3 “C) below the setting on the display.
Outside Temperature: This sensor is on the right side
of the upper radiator support in the grille opening. This
is what you usually see on the display.
If the outside temperature goes up, the displayed
temperature will not change until:
a Vehicle speed is above 25 mph (40 km/h) for at least
0 Vehicle speed is above 45 mph (72 km/h) for
This delay helps prevent a false reading. If vehicle speed
remains above
25 mph (40 km/h) or the temperature
goes down, the display is updated immediately.
If your vehicle has been off for more than three hours,
the current outside temperature will be stored in the
system when you start the vehicle.
Inside temperature: This sensor is in the center air
outlet
on the passenger side.
If you block or cover either interior sensor, the system
will give a false reading.
3 minutes, or
1 1/2 minutes.
Automatic Control
The system will adjust to maintain the temperature you
set. It will select the best fan speed and aifflow setting to
keep you comfortable with the least amount of noise.
Press the arrows on the TEMP SET switch’to set a
comfortable temperature. Then press AUTO
and the fan
speed will adjust automatically unless you press the
arrows on the switch.
Manual Heating
The heater works best if you keep your windows closed
while using it.
Press the arrows on the TEMP SET switch to set a
comfortable temperature. Then press HEATER and, if
you don’t like the automatic setting, press the arrows on
the fan speed switch.
In AUTO FAN on cold days, the
fan will stay off until the coolant warms up enough to
heat your vehicle.
If your vehicle has an engine coolant heater and you use
it in cold weather,
0 OF (- 18 O C) or lower, your heating
system can provide heat more quickly because the
engine coolant is already warmed. See “Engine Coolant
Heater” in the Index.

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
1 @ synthetic oil, which meets all requirements for
your vehicle.
Substitute Oil (LTl Only): When adding oil to
maintain engine oil level, oil meeting GM Standard
GM47
18M may not be available. You can add substitute
oil designated
SAE 5W-30 with the “Starburst” symbol
or API Service SH at all temperatures. If temperatures
are above
0” F (- 18 O C), you may substitute SAE
1OW-30 with the “Starburst” symbol or API Service
SH
oil. This oil should not be used for an oil change.
Substitute Oil (LT5 Only): When adding oil to
maintain engine oil level,
if an oil meeting GM Standard
GM47
18M is not available, you can use oil designated
SAE 1OW-30 with the “Starburst” symbol or API
~ Service SH at all temperatures. This oil 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
See if any one of these is true for you:
0 Most trips are less than 5 to 10 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.
If any one of these is true for your vehicle, you need to
change your oil and filter every 3,000 miles
(5 000 km)
or 3 months -- whichever comes first. (See “Engine Oil
Life Monitor” in the Index.)
If none of them is true, change the oil and filter every
7,500 miles (12 500 km) or 12 months -- whichever
comes first. (See “Engine Oil Life Monitor” in the
Index.)
Engine Coolant Heater
An engine coolant heater can be a big help if you have
to
park outside in very cold weather, 0” F (- 1 8 O C) or
colder. If your vehicle has this feature, see “Engine
Coolant Heater” in the Index.

To add lubricant when the level is low, use Axle
Lubricant (GM Part
No. 12345977) or SAE SOW-90
GL-5 gear lubricant.
To completely refill after draining,
add
4 ounces (1 18 ml) of Limited-Slip Differential
Lubricant Additive (GM Part
No. 1052358). Then fill to
the bottom of the filler plug hole with Axle Lubricant
(GM Part
No. 12345977) or SAE 8OW-90 GL-5 gear
lubricant.
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 or if you need to add coolant to your
high fill reservoir, see “Engine Overheating” in the
Index.
The proper coolant for your Corvette will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 262 “F (128 ” C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights work as they should. Use a mixture
of one-half
clean water (preferably
distilled) and one-half antifreeze that meets
“GM
Specification 1825M,” which won’t damage aluminum
parts.
You can also use a recycled coolant conforming to
GM Specification 1825M with a complete coolant flush
and refill. Use GM Engine Coolant Supplement (sealer)
with any complete coolant flush and refill. If
you use
this mixture, you don’t need to add anything else.
