1997 CHEVROLET CORVETTE coolant level

Downloaded from www.Manualslib.com manuals search engine Racing or Other Competitive Driving
See your Warranty Book before using your Corvette for
racing or other competitive driving.
NOTICE:
If you use your Corvette for racing or other
competitive driving, your engine may use more
oil than it would with normal use. Low oil levels
can damage the engine. Be sure to check the oil
level often during racing or other competitive
driving and keep the level at or near the upper
mark on the engine oil dipstick.
You may need
to add oil. See “Adding Oil” under “Engine” in
the Index.
Engine Coolant Heater
(Canada Only)
The engine coolant heater is located on the driver’s side
of the engine under the manifold. The electrical cord is
attached to the generator bracket assembly, between the
generator and the windshield washer fluid tank.
In very cold weather,
0 OF (- 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.

Downloaded from www.Manualslib.com manuals search engine A Typical Cold Weather Example:
Your vehicle has been parked outside ~ver~~ight in
cold weather (below 32 OF/ 0" C) and you have set
the driver temperature at 73 OF (23
"C) and have selected
the AUTO mode. The system will automatically adjust
the temperature output to maximum heating. The fan
will start at a low speed. This
is to avoid blowing cold
air into the vehicle. The length of the delay depends
on the amount of time since the engine was last started,
the outside temperature and the engine coolant
temperature. As the coolant warms up, the fan speed
will gradually increase. Air will flow to the floor with
some air to the windshield to prevent fogging under
most normal conditions.
As the interior
of the vehicle warms up to your comfort
set temperature, the fan speed will decrease and the
temperature output may become cooler. If the interior
temperature continues to warm up due to heating from
the sun or outside temperature increases, the system
may switch to other air delivery modes (typically
DEFOG or BI-LEVEL).
A vpical Hot Weather Example:
Your vehicle has Seen parked outside all day in hot
weather (above
70 OF/ 2 1 O C) and you have set the
driver temperature at
73 "F (23 O C) and have selected
the AUTO mode. The system will automatically adjust
the temperature output to maximum cooling. The blower
will start at a low speed momentarily to push the hot
air to the floor of the vehicle and then
go to a higher
blower speed with cold airflow out of the instrument
panel outlets. A small amount of airflow will continue
through the lower ducts to cool the floor area.
The air intake may start in the recirculated mode for
maximum cooling performance. As the interior of the
vehicle cools down to your comfort set temperature,
the fan speed will decrease and the temperature output
may become warmer. The air intake may shift from
recirculation to fresh air mode.
If the interior continues
to cool due to a decrease in the amount
of heat the
vehicle is absorbing from the sun or a decrease in the
outside temperature, the system could switch to other air
delivery modes (typically BI-LEVEL or DEFOG).

Downloaded from www.Manualslib.com manuals search engine Heating
The heater works best if you keep your windows closed.
Maximum heating will occur when airflow direction
is in the lower mode and the temperature control knob
(on a manual climate control system) is all the way in
the red area. These settings will be selected by the
Automatic Electronic Dual Climate Control System if
operating in AUTO when maximum heating is required.
The BI-LEVEL setting is designed for use on sunny
days when the air is only moderately warm or cool.
On days like these, the sun may adequately warm
your upper body, but your lower body may not be
warm enough. The BI-LEVEL setting will direct
cooler airflow to your upper body and warmer air
to the floor area.
If you have the optional engine coolant heater and use
it during cold weather
0°F (- 18OC) or lower, your
heating system will provide heat more quickly because
the coolant is already warmed. See “Engine Coolant
Heater” in the Index.
Defogging and Defrosting
To rapidly defrost the windshield, the FRONT defrost
mode (electronic dual climate control system) or defrost
mode (manual control system) should be used and the
fan speed should be adjusted to the highest speed. With
the manual control system,
turn the temperature control
knob all the way to the red area.
To keep the windshield clear and provide heated air to
the floor area of
the vehicle, use the DEFOG setting.
Your vehicle is equipped with side window defogger
vents located near the side rearview mirrors.

Downloaded from www.Manualslib.com manuals search engine The coolant level should be at or above the FULL
COLD mark.
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.
Heater and radiator hoses, and other engine
parts, can be very hot. Don’t touch them.
If you
do, you can be burned.
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.
1 NOTICE:
Engine damage if you keep running your engine
without coolant isn’t covered by your warranty.
See “Overheated Engine Protection Operating
Mode” in the Index.
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
Surge Tank
If you haven’t found a problem yet, but the coolant level
isn’t at the FULL COLD mark, add a
50/50 mixture of
clean water (preferably distilled) and DEX-COOL@
coolant at the coolant surge tank, but be sure the cooling
system, including the coolant surge tank pressure cap,
is
cool before you do it. (See “Engine Coolant” in the
Index for more information.)
Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They
are under pressure, and if you turn the coolant
surge tank pressure cap
-- even a little -- they
can come out at high speed. Never turn the cap
when the cooling system, including the coolant
surge tank pressure cap, is hot. Wait for the
cooling system and coolant surge tank pressure
cap to cool if you ever have to turn the
pressure cap.

engine and let it run until you can feel the upper
radiator hose getting hot. Watch out for the
engine fans.
By this time, the coolant level inside the coolant
surge tank may be lower. If the level is lower, add
more of the proper mix to the coolant surge tank
until the level reaches the
FULL COLD mark.
5. Then replace the pressure cap. Be sure the pressure
cap
is tight.
