1998 CADILLAC ELDORADO coolant temperature

Downloaded from www.Manualslib.com manuals search engine To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 11 0-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. Before starting the engine, be sure to unplug
and 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 dealer
in the area where you’ll be parking your
vehicle. The dealer can give you the best advice for that
particular area.

Warning Light
This light tells you that the
engine has overheated. You
should stop your vehicle
and
turn the engine off as
n
chime should also sound if -
soon as possible. A warning
this light comes on.
As
a check, the light should come on for a few seconds
when
you start your engine. In the section “Problems on
the Road,” this manual explains what
to do. See “Engine
Overheating’‘ in the Index.
Engine Coolant Temperature Gage
This gage shows the
engine coolant temperature. If the gage pointer moves
into the
red area, the engine
is
too hot.
That reading means the same thing as the warning
light -- the engine coolant has overheated. In the section
“Problems on the Road,” this manual explains what
to
do. See “Engine Overheating” in the Index.

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.
ENGINE HOT - AC OFF - 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.
ENGINE MISFIRE -- EASE OFF GAS

Downloaded from www.Manualslib.com manuals search engine 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 from the air outlets. As the air
is cooled,
the airflow will move through
the air conditioning
outlets. If you start your vehicle with the fan setting
on
HI, it will skip the air conditioning 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
normal 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 automatic operation when the ignition is
shut off and
then turned back on.
Manual Operation
You may manually adjust the air delivery mode or
fan speed.
/J AC: This setting directs airflow through the
A0
middle instrument panel outlets.
l# BI-LEVEL: This setting directs air into your
vehicle in two ways.
Cool air is directed to the upper
portion
of your body through the four instrument panel
outlets while warmed air is directed to the floor.
'fl HEATER/DEFROST: This setting directs air to
the floor outlets and toward the windshield.
I# HEATER: This'setting directs warmed air
through the
floor outlets. Some warm air is diverted to
the windshield to minimize fogging.

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.

symbol
on it 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 warm, 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
arrow 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 LO AUTO is shown
on the display.
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 on the
display when the system
is OFF.
AC: Press this button to turn the air conditioning on and
off. The system will cool and dehumidify the air inside
the vehicle. In the
AUTO mode, the display will show
that
AC is active, but the air conditioning compressor
only operates when the system determines it
is needed.
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.

You will find an ENGINE COOLANT HOT, IDLE
ENGINE message or an ENGINE OVERHEATED,
STOP ENGINE message
on the Driver Information
Center (DIC).
You will also hear a chime. There is also
an engine temperature warning light and/or gage
on the
instrument panel. See “Engine Coolant Temperature
Warning Light” or “Engine Coolant Temperature Gage”
in the Index.
Overheated Engine Protection
Operating
Mode
Should an overheated engine condition exist and the
message ENGINE OVERHEATED
STOP ENGINE is
displayed, an overheat protection mode which alternates
firing groups
of four cylinders helps prevent engine
damage. In this mode, you will notice a loss in power and
engine performance. 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.
-~
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 will be severely degraded. Repair
the cause of coolant loss, 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 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. See “Overheated
Engine Protection Operating Mode” in the Index.
If No Steam Is Coming From Your Engine
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.
Tow a trailer.
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. Dial temperature control to the highest heat setting
and open the windows, as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- OVERDRIVE (0) or THIRD (3).
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 rqinutes while you’re parked,
to see
if the warning stops. But then, if you still have the
warning,
turn off the engine and get everyone out of
the vehicle until it cools down. Also, see “Overheated
Engine Protection Operating Mode” listed previously
in this section.
You may decide not
to lift the hood but to get service
help right away.

The cooling s stem in your vehicle is filled with
DEX-COOL engine coolant. This coolant is designed
to remain in your vehicle for
5 years or 150,000 miles
(240 000 km) whichever occurs first, if you add only
DEX-COOL’ extended life coolant.
J
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 DEX-COOL@
coolant will:
0 Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265 “F (1 29°C).
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights and gages work as
they should.
NOTICE:
When adding coolant, it is important that you
use only
DEX-COOL@ (silicate-free) coolant.
If coolant other than DEX-COOL is added to
the system, premature engine, heater core or radiator corrosion may result. In addition, the
engine coolant will require change sooner
-0 at
30,000 miles (50 000 km) or 24 months,
whichever occurs first. Damage caused by the
use
of coolant other than DEX-COOL@ is not
covered by your new vehicle warranty.
