1997 CADILLAC CATERA coolant temperature

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 normal, grounded 110-volt AC outlet.
/ CA-‘TIC’J:
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 Catera 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 the
car and turn
the engine
off as soon as
possible.
A warning chime
should also sound if
this
light comes on.
As a check, the light should come on for a few seconds
when you
start the engine. In the section “Problems on
the Road,” this manual explains what to do. See “Engine
Overheating” in the Index.
Engine Coolant Temperature Gage
C &
This gage shows the engine
coolant temperature.
If the
gage pointer moves into
the red area, the engine
is
too hot!
This reading means the same thing as the warning
light
-- the engine coolant has overheated. You should
stop the car and turn the engine off as soon as possible.

Downloaded from www.Manualslib.com manuals search engine In cold weather, when the system senses the need for
heat, airflow will be directed out of the floor outlets.
As
the interior temperature approaches a desired setting, the
blower speed will decrease.
To maintain interior
comfort, the airflow may move to the instrument panel
air outlets and floor outlets (bi-level mode). On bright
sunny days in cold weather, the airflow may come out of
the air conditioning outlets
(AC mode) to maintain
comfort and prevent stuffiness.
If your vehicle is sitting out on a hot day and you have it
set for automatic operation, the
air will first flow out of the
floor
air outlets during cool down. 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.
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 airflow 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.
Manual Operation
You may manually adjust the air delivery mode or
fan speed.
'# HEATERDEFROST: This setting directs air to
the floor outlets and toward the windshield.
3 AC: This setting directs airflow through the middle
instrument
panel outlets.
'!! 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 middle instrument
panel outlets while warmed air is directed to the floor.
w.
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.

Downloaded from www.Manualslib.com manuals search engine * FAN SPEEDS: Press the driver’s side
TEMP/AUTO knob to set the fan speed for automatic
operation. 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 reach the highest position of the display.
If you want the blower fan at a low speed, press the
down arrow button until the lowest position is displayed.
ON/OFF: Press this button to turn the system off.
Press this button again to turn the system back on.
Turning the climate control system on in this way
will recall all previous manually set mode settings.
If the system is turned on by pushing the driver’s
TEMP/AUTO knob for automatic operation, all
of the
previous manually set mode settings will be changed
back to the fully automatic mode.
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 automatic operation
mode, the display
will show
AC OFF when the air conditioning has been
turned
off.
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 automatic operation 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.

Downloaded from www.Manualslib.com manuals search engine A 50/50 mixture of water and the proper coolant for
your Catera will:
0 Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265 "F (1 29 " C).
0 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 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
-- 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.
What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half
DEX-COOL' coolant which
won't damage aluminum parts.
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@ coolant.

Downloaded from www.Manualslib.com manuals search engine Surge Tank Pressure Cap Power Steering Fluid
NOTICE:
The surge tank cap is a 15 psi (105 kPa)
pressure-type cap and must be tightly installed to prevent coolant loss and possible engine
damage from overheating.
If the surge tank pressure cap needs to be replaced, a
GM 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 the thermostat needs to be replaced, a GM thermostat
is recommended. The
power steering fluid reservoir
is located between
the battery and the brake master cylinder on the driver’
side
of the engine.
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.
