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.

BI-LEVEL can
heat or cool outside air and direct it in
two directions.
Press the arrows on the TEMP SET switch to set a
comfortable temperature. Press VENT and, if you don’t
like the automatic setting, press the arrows on the fan
speed switch.
Manual Ventilation
For mild outside temperatures, when little heating or
cooling is needed, you can still direct outside air through
your vehicle.
Press the arrows on the TEMP SET switch to set a
comfortable temperature. For ventilation, the system can’t cool the vehicle below the outside temperature.
Press VENT and, if you don’t like the automatic setting,
press the arrows on the fan speed switch. The air conditioner
works best if you keep your
windows closed.
On very hot days: open the windows
just long enough for the hot air to escape.
Press the arrows
on the TEMP SET switch to set a
comfortable temperature. Press RECIRCULATE. After
cool-down, adjust the airflow to another setting. The
compressor works in all settings except
VENT and
HEATER and at all temperatures above freezing.
Press the arrows on the fan speed switch
if you don’t
like the automatic setting. In
AUTO FAN on hot days,
the fan speed will be low at first to help get rid
of the
hot inside air.
When the air conditioner is on, you may notice slight
changes in your vehicle’s engine speed and power. This
is normal because the system is designed to cycle the
compressor on and off to keep the desired temperature
and help fuel economy.

isn’t, you may have a leak in the radiator hoses, heater
hoses, radiator, water pump or somewhere else in the
cooling system.
NOTICE:
Engine damage from running your engine
without coolant isn’t covered by your warranty.
If there seems to be no leak, with the engine on check to
see if the electric engine fan(s) are running.
If the engine
is overheating, both fan(s) should be running. If they
aren’t, your vehicle needs service.
How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the ,coo,lant level
isn’t at or above the COLD mark, add
a 50MI mixture
of clean water (preferably distilled) and a proper
antifreeze at the coolant recovery tank. (%e “Engine
Coolant” in the Index for more information about the
proper coolant mix.)

Downloaded from www.Manualslib.com manuals search engine What to Use What to Use
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.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
If you use an improper coolant mix, your engine
could overheat and be badly damaged. The
repair cost wouldn’t be covered by your
warranty.
Too much water in the mix can freeze
and crack the engine, radiator, heater core and other parts.
Adding Coolant
To Check Coolant
When your engine is cold, check the dipstick on the cap
of the coolant recovery tank. The coolant level should
be at COLD, or a little higher. When your engine is
warm, the level on the dipstick should be up to the HOT,
or a little higher. Your
Corvette also has
a high fill reservoir located at the
right rear of the engine compartment.
If the recovery tank
is very low or empty, also add
coolant to the
high fill reservoir. To add coolant at the
high fill reservoir, see “Engine Overheating” in the
Index.
6-28

Downloaded from www.Manualslib.com manuals search engine To Add Coolant to the Recovery Tank
If you need more coolant, add the proper mix at the
coolant recovery tank,
but only when your engine is
cool. If the tank
is very low or empty, also add coolant
to the coolant high fill reservoir, see “Engine
Overheating” in the Index
for information.
Add coolant mix at the recovery tank, but be careful not
to spill it.
