1996 CHEVROLET CORVETTE coolant temperature

Downloaded from www.Manualslib.com manuals search engine Engine Coolant Heater (Canada Only)
In very cold weather, 0°F (- 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.
To Use the Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 110-volt AC outlet.
A CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into
a properly grounded three-prong
110-volt
AC outlet. If the cord won’t reach, use a
heavy-duty three-prong extension cord rated for
at least
15 amps.
4. After you’ve used the coolant heater, be sure to store
the cord as it was before to keep
it away from
moving engine parts. If you don’t, it could be
damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of
oil you have, and some other things. Instead of
trying to list everything here, we ask that you contact
your Chevrolet dealer in the area where you’ll be
parking your vehicle. The dealer can give you the best
advice for that particular area.

The analog gauges provide a quick visual reference to
the actual measurements of these gauges. However, you
must keep in mind that the gauges aren't linear. This
means that the middle mark
is not a temperature halfway

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.

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.

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.
