1996 CHEVROLET CORVETTE heater

Downloaded from www.Manualslib.com manuals search engine Snow can trap exhaust gases under your vehicle.
This can cause deadly
CO (carbon monoxide) gas
to get inside. CO could overcome you and kill
you. You can’t see it or smell
it, so you might not
know it
is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking your exhaust pipe. And check
around again from time to time to be sure snow
doesn’t collect there.
Open a window just
a little on the side of the
vehicle that’s away from the wind. This will help
keep
CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlamps. Let the heater run for awhile.
Then, shut the engine
off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But do it as little as possible. Preserve the
fuel as long as you can. To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour or
so until help comes.

If you get the overheat warning but see or hear no
steam, the problem may not be too serious. Sometimes
the engine can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
If .you get the overheat warning with no sign of steam,
try this for a minute or
so:
1. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (@)
or DRIVE (D) for automatic transmissions. If you no longer have the overheat warning, you can
drive. Just
to be
safe, drive slower for about 10 minutes.
If the warning doesn’t come back on, you can
drive normally.
If the warning continues, pull over, stop, and park your
. vehicle right away.
If there’s still no sign of steam, you can idle the engine
for two or three minutes while you’re parked, to see
if the warning stops. But then,
if you still have the
warning,
turn oJjcthe engine and get everyone out of
the vehicle until it cools down.
You may decide not to lift the hood but to get service
help right away.

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.

Downloaded from www.Manualslib.com manuals search engine 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 SOW-90 GL-5 gear
lubricant.
Engine Coolant
The cooling system in your vehicle is filled with new
DEX-COOL (orange-colored, silicate-free) engine
coolant. This coolant is designed
to remain in your
vehicle for
5 years or 100,000 miles (166 000 km),
whichever occurs first.
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.
A 50/50 mixture of water and the proper coolant for
your Corvette will:
0 Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 265 OF ( 129 O C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
0 Let the warning lights and gauges work as they should.
NOTICE:
When adding coolant it is important that you use
DEX-COOL (orange-colored, silicate-free)
coolant meeting GM Specification 6277M.
If
silicated coolant 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.

Downloaded from www.Manualslib.com manuals search engine What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half
DEX-COOL TM (orange-colored,
silicate-free) antifreeze that meets GM Specification
6277M, which won’t damage aluminum parts. Use
GM Engine Coolant Supplement (sealer) (GM
Part
No. 3634621) with any complete coolant change. 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 TM (orange-colored.
silicate-free) antifreeze.
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.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
NOTICE:
If you use the proper coolant, you don’t have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.
