coolant temperature CADILLAC DEVILLE 1996 7.G Owners Manual

Downloaded from www.Manualslib.com manuals search engine To use the coolant heater:
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
.3. Plug it into a nonnal, grounded 110-volt AC outlet.
I 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 Cadillac dealer in the area where you’ll be parking
your vehicle.
The dealer can give you the best advice for
that particular area.

Driver Information Center Messages
These messages will appear if there is a problem sensed
in one of your vehicle’s systems. Vehicles that are first
sold
in Canada will have a number after each message.
This number helps to identify the message which is only
displayed in English.
A/C OFF FOR ENGINE PROTECTION - 16: This
message displays when the engine coolant becomes
hotter than the normal operating temperature. To avoid
added strain on a hot engine, the air conditioning
compressor is automatically turned
off so that air
conditioned air
is not delivered. If the coolant
temperature returns
to normal, you must select AC to
return to a normal
A/C compressor operation. If this
message continues to appear, have the system repaired
as soon as possible to avoid compressor damage.
APPLY BRAKE TO SHIFT - 46: This message will
appear if your vehicle is in PARK (P) for about 15 seconds
and the brake is not pressed
in. Remove the message by
holding the
OFF and the blue (cooler) button on the
Electronic Climate Control panel for about five seconds. Hold
the same two buttons again to redisplay the message.
BATTERY NO CHARGE - 07: This message will
appear
if the battery is not being charged. Have the
electrical system checked by your Cadillac dealership at
your earliest convenience.

Downloaded from www.Manualslib.com manuals search engine CHECK COOLANT LEVEL - 02: This message will
appear when there is a low level
of engine coolant. Have
the cooling system serviced by a Cadillac technician as
soon
as possible.
CHECK FUEL GAGE - 39: This message will appear
when the fuel supply is less than four gallons (15.2
L)
and the display is turned off.
CHECK OIL LEVEL - 36: For correct operation of
the low oil sensing system, your vehicle should be on a
level surface.
A false CHECK OIL LEVEL message
may appear
if the vehicle is parked on grades. The oil
level sensing system does not check for actual oil level
if the engine has been off for a short period of time, and
the oil level is never sensed while the engine is running.
If the CHECK OIL LEVEL message appears, and your
vehicle has been parked on level ground with the engine
off for at least 30 minutes, the oil level should be
checked
by observing the oil dipstick. Prior to checking
the oil level be sure the engine has been off for five
minutes and your vehicle is on a level surface. Then
check the dipstick and add oil
if necessary. See “Engine
Oil”
in the Index.
CHECK WASHER FLUID - 25: This message will
appear for several seconds indicating that
you need
washer solvent.
CRUISE ENGAGED - 43: This message will appear
for a few seconds
when you select a speed at which
to cruise.
DOOR OPEN - 141: The passenger’s door is open or
ajar when this message appears. The vehicle’s engine
must be running and the transaxle not
in.PARK (P) for
this message to display.
A chime will also sound when
the vehicle’s speed is greater than
5 mph
(8.1 km/h).
DRIVER DOOR OPEN - 140: This message
will display when the vehicle is being shifted out
of
PARK (P) with the engine running to signal that
the driver’s door is open or ajar.
A chime will also
sound when the vehicle’s speed is greater than
5 mph
(8.1 W).
ENGINE COOLANT HOT-IDLE ENGINE - 44:
This message will appear when the engine coolant
temperature
is over 248°F (126°C). To avoid added
strain on a hot engine, turn off the climate control
system. Stop and allow your vehicle to idle until
it cools
down
or the message is removed. If it does not cool
down,
turn off the engine and have it serviced before
driving it again. Severe engine damage can result from
an overheated engine. See “Engine Overheating” in
the Index.

If your vehicle is sitting out on a hot day and you have
it set -on
AUTO, the air will first flow out the floor air
outlets for a
few seconds. That is normal. This is to
expel hot air in the air outlets.
As the air is cooled, the
aifflow will move through the
A/C outlets. If you start
your vehicle with the fan setting on
HI, it will skip the
A/C Purge.
To avoid blowing cold air in cold weather, the system
will delay turning on the fan until warm air is available.
The length of delay depends on the outside air
temperature, engine coolant temperature or the time
since the engine was last started.
As the coolant warms
up, the blower fan speed will gradually increase
and air
will flow from the heater outlets, with some aifflow to
the windshield to prevent fogging under most nonnal
conditions.
If you leave your vehicle, the system will remember the
control setting
the next time you start your engine,
except for recirculation and defrost. Each ignition cycle
cancels recirculation, whereas,
DEFROST will change
to
AUTO when the ignition is shut off and then turned
back on.
Manual Operation
RECIRCULATION: Press this button to limit the
amount of fresh air entering your vehicle. This is helpful
when you are trying to cool the air quickly or limit odors
entering your vehicle. In the
AUTO mode, the system
will use recirculation as necessary to cool the air.
Pressing the recirculation button will change the
operation to a manual mode and the air will recirculate
non-stop. Press this button again to
turn off the
recirculation feature.
If you notice
the windows fogging, press the
recirculation button
to exit the recirculation mode.
OFF: Press this button to turn the system off.
Fresh air will continue to flow through the vehicle,
and the system will try
to maintain the previously set
temperature. The outside temperature will show in
the display when the system is off.
@ DE-ICE (Option): Pressing this button helps to
remove ice or frost from the windshield. See "Heated Windshield" later in this section.

Downloaded from www.Manualslib.com manuals search engine DEFOG: Press thl's button to divide the air between the
windshield and
the heater outlets. This is useful when
fog appears on the windshield or side glass due to
sudden rain or snowy conditions. This feature is not
available with the heated windshield option.
AUTO/ECON: Press this button to switch between
AUTO and ECON. The ECON setting attempts to keep
air at a selected temperature, however, it does not
remove humidity from the air. Use this setting in cold
or
cool weather to save fuel. The AUTO setting is used
when it's warm outside and you need
to cool the air in
order to maintain a selected temperature and blower
speed.
FAN SPEEDS: Press the button with the fan
symbol until AUTO is displayed on the screen. At this
setting, the fan speed
is automatically controlled. If it is
cold outside, the blower may not
run in the maximum
high
fan speed right away. The system checks the temperature of the engine
coolant to assure it is warm
enough to provide heat. When
the engine coolant is
wm, the controller allows the fan to gradually increase
to a higher speed. This prevents cold air from blowing
into the passenger compartment.
If you want the blower
fan at a high speed, press the up arrow button until you
see HI
on the display. If you want the fan speed to be
automatic, but
you like the fan speed to be higher than
the
AUTO setting, press the fan symbol button until HI
AUTO
is shown on the display. If you want the blower
fan at a
low speed, press the down mow button until
LO is shown on the display. If you want the fan speed to
run lower than the
AUTO setting, press the button until
AUTO LO is shown on the display.
9 DEFROST: Press this button to quickly remove
fog or frost from the windshield.
This setting sends most
of the airflow to the windshield with only a small
amount to the floor outlets.

You will find an ENGINE COOLANT HOT-IDLE
ENGINE message
or a STOP ENGINE ENGINE
OVERHEATED message on the DIC. There is also an
engine temperature warning light
on the instrument
panel. See “Engine Temperature Warning Light” in the
Index.
Overheated Engine Protection Operating
Mode
Y
Should a low coolant condition exist and the message
STOP ENGINE
ENGINE OVERHEATED is displayed,
an overheat protection mode which alternates firing
groups
of four cylinders helps prevent engine damage.
This operating mode
allows your vehicle to be driven
to a safe place in
an emergency; you may drive up to
50 miles (80 km). Towing a trailer in the overheat
protection mode should be avoided.
I NOTICE:
After driving in the Overheated Engine
Protection Operating Mode,
to avoid engine
damage, allow the engine to cool before
attempting any repair. The engine oil may be
severely degraded. Change the
oil and reset the
oil life indicator. See “Engine Oil, When to
~ Change” in the Index.

Downloaded from www.Manualslib.com manuals search engine 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 0o0 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, see “Engine Overheating” in
the Index.
A 50/50 mixture of water and the proper coolant for
your Cadillac will:
Give freezing protection down to -34°F (-37 O C).
Give boiling protection up to 265 “F (129 “C).
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
Let the warning lights and gages work as they should.
NOTICE:
When adding coolant it is important that you use
DEX-COOL TM (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.
What
to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half
DEX-COOL (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.
A special procedure is required for adding sealer; see the
Cadillac service manual.
(To order a service manual, see
“Service and Owner Publications”
in the Index.)

Adding Coolant
If you need more coolant, add the proper mix at the
surge tank, but only when the engine is cool.
I A CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and
it will burn if the engine parts are hot
enough. Don't spill coolant on a hot engine.
~~~ ~ ~~~~~~~
When replacing the pressure cap, make sure it is tight.
Surge Tank Pressure Cap
I NOTICE:
The surge tank cap is a 15 psi (105 kPa)
pressure-type
cap and must be tightly instalfed to
prevent coolant loss and possible engine damage
from overheating. Be sure
the arrows on the
cap line up.
If the surge tank pressure cap needs to be replaced, a
General Motors cap
is recommended.
Thermostat
Engine coolant temperature is controlled by a thermostat
in the engine coolant system. The thermostat stops the
flow of coolant through the radiator until the coolant
reaches a preset temperature.
If your thermostat needs to be replaced, a General
Motors thermostat
is recommended.

Downloaded from www.Manualslib.com manuals search engine Power Steering Fluid
The power steering fluid reservoir
is located next to
the coolant surge tank on
When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system or
you hear an unusual noise.
A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
How To Check Power Steering Fluid
When the engine compartment is cool, unscrew the cap
and wipe the dipstick with a clean rag. Replace the cap
and completely tighten it. Then remove the cap again
and look at the fluid level on the dipstick.
The level should be at the
FULL COLD mark. If
necessary, add only enough fluid to bring the level up to
the mark.
What to Use
Refer to the Maintenance Schedule to determine what
kind of fluid to use. See “Recommended Fluids and
Lubricants” in the Maintenance Schedule booklet.
Always use the proper fluid. Failure to use the proper
fluid can cause leaks and damage hoses and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer’s instructions before use. If you will be
operating your vehicle
in an area where the temperature
may fall below freezing, use a fluid that has sufficient
protection against freezing.
