1996 CHEVROLET CORVETTE engine coolant

Downloaded from www.Manualslib.com manuals search engine Automatic Transmission Fluid Temperature Reading
Automatic transmission
fluid temperature will
be displayed if you press
the GAUGES button on
the trip monitor until
AUTO appears.
The number that appears next to the fuel gauge is the
automatic transmission fluid temperature. If
LO appears,
the temperature is below 32°F (0°C). It’s
normal for the transmission fluid temperature to
vary, depending on the type
of driving you do and
weather conditions. If you drive on long grades on a hot
day, the transmission fluid temperature will be higher
than normal driving on a cold day. If you
drive your
Corvette at high speeds with a lot of stop-and-go or fast
accelerations, your transmission fluid temperature may
also be higher.
If the transmission fluid exceeds
280” F (1 38 “C), the
CHECK GAUGES light will come on and HI AUTO
will be displayed next to the transmission fluid
temperature when you toggle through the GAUGES
button. You should move the shift lever to DRIVE
(D)
and continue driving at a slower, constant speed.
Monitor the transmission fluid temperature and allow it
to cool to 180°F (82°C) to 200°F (93°C). Then, you
should check the transmission fluid level for a low fill or
overfill condition and bring your Corvette in for service
as soon as possible if the oil is too low or overfilled.
(See “Automatic Transmission Fluid” in the Index.)
Also, check the engine coolant temperature. If it’s too
hot, see “Cooling System” in the Index.

days. This setting cools outside air and directs it through
the instrument panel vents.
The air conditioning compressor operates in NORMAL
A/C, as well as RECIRCULATE, BI-LEVEL and
DEFROST. It only works when the outside temperature
is above freezing. When the air conditioning compressor
is on, you may sometimes 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 cooling and help
fuel economy.
+,d BI-LEVEL: This setting cools or heats outside air
and directs it through the instrument panel vents and the
floor ducts.
de
do
do /I VENT: Air flows through the instrument panel
vents. The air conditioning compressor does not run in
VENT mode.
wg HEATER: This setting directs most of the air
through the floor ducts and some of the air through the
defroster vents. The air conditioning compressor does
not run in HEATER mode.
DEFROST: This setting directs most of the
air through the windshield defroster and side window
defogger vents and some of the air through the
floor ducts.
Heating
The heater works best if you keep your windows closed
while using it.
Press HEATER and
FAN UP, then slide the temperature
control lever to a comfortable setting.
If your vehicle has an engine coolant heater and you
use it in cold weather,
0°F (- 18 "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.

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 AUTO 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 "F (- 18 O C) or lower, your heating
system can provide heat more quickly because the engine
coolant is already warmed. See "Engine Coolant Heater"

Manual Bi-Level
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 BI-LEVEL 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.

You will find an engine coolant temperature gauge on
the instrument cluster and a
LOW COOLANT light on
the Driver Information Center.
If Steam Is Coming From Your Engine
Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay away
from the engine
if you see or hear steam coming
from it. Just turn it
off and get everyone away
from the vehicle until it cools down. Wait until
there is no sign of steam or coolant before
opening the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch fire.
You or
others could be badly burned. Stop your engine if
it overheats, and get out of the vehicle until the
engine is cool.
I NOTICE:
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be
covered by your warranty.

Downloaded from www.Manualslib.com manuals search engine When you decide it’s safe to lift the hood, here’s what
you’ll see:
An electric fan under the hood can start up even
when the engine is not running and can injure
you. Keep hands, clothing and tools away from
any underhood electric fan.
If the coolant inside the coolant recovery tank is boiling,
don’t do anything else until it cools down.

Downloaded from www.Manualslib.com manuals search engine When it is cool, remove the coolant recovery tank cap
and look at the dipstick.
The coolant level should be at or above
COLD. If it
isn’t, you may have a leak in the radiator hoses, heater
hoses, radiator, water pump
or somewhere else in the
cooling system.
.h CAUTION:
*
8’
Heater and radiator hoses, and other engine
parts, can be very
hot. Don’t touch them. If you
do, you can be bul‘ned.
Don’t run the engine
if there is a leak. If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
I NOTICE:
I
Engine damage from running your engine
without coolant isn’t covered by your warranty.
I
If there seems to be no leak, with the engine on, check to
see if the electric engine fans are running.
If the engine
is overheating, both fans should be running. If they
aren’t, your vehicle needs service.

Downloaded from www.Manualslib.com manuals search engine How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at
or above the COLD mark, add a 50/50 mixture
of
clean water (preferably distilled) and DEX-COOL“
(orange-colored, silicate-free) antifreeze at the coolant
recovery tank. (See “Engine Coolant” in the Index
for more information.)
-
A CAUTION:
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 TM antifreeze.
NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mix.
