1995 PONTIAC PONTIAC coolant temperature

Anti-Lock Brake System Active Light
(Option)
When your anti-lock system
is adjusting brake pressure
to help avoid a braking skid,
the
LOW TRAC light will
come on.
Slippery road conditions will exist
if this light comes on,
so adjust your driving accordingly. The light will stay on
for a few seconds after the system stops adjusting brake
pressure.
The
LOW TRAC light also comes on briefly, as a bulb
check, when the engine is started. If the light doesn’t
come on then, have it fixed
so it will be there to tell you
when the system is active.
Engine Coolant Temperature Light
4b 100
This light tells you that
your engine coolant has
overheated
or your radiator
cooling fan is not working.

En.gine Coolant Temperature Gage
You have a gage that
shows the engine coolant
temperature.
If the gage
pointer moves into the red
area, your engine is too hot!

That reading means the same thing as the warning light.
It means that your engine coolant has overheated. If you
have been operating your vehicle under normal driving
conditions, you should pull
off the road, stop your
vehicle and turn off the engine
as soon as possible.

In “Problems on the Road,” this manual shows what to
do. See “Engine Overheating” in the Index.
Low Coolant Warning Light
If this light comes on, your
system is low on coolant
and the engine may
overheat. See “Engine
Coolant” in the Index and
have your vehicle serviced as
soon as you can.

Control Buttons
The trip calculator has three buttons that control its
functions.
MODE: Press this button to change the mode being
displayed.
EM: Press this button to change the display from
English to metric units or metric to English.
RESET Press this button for one second to reset the
mode displayed.
If you push and hold RESET for more
than five seconds, all the modes will reset. You can’t
reset
INST ECON, RANGE or EXT TEMP.
Head-Up Display (Option)
If you have the Head-Up
Display (HUD), you can see
the speedometer reading, in
English or metric units,
displayed “through” the
windshield. The
HUD also shows these lights when they are
lit on
the instrument panel:
Turn Signal Indicators
0 High-Beam Indicator Symbol
Low Fuel Symbol
0 Oil Warning Symbol
0 Coolant Temperature Symbol
Charging System Symbol
When you sit straight in your seat, the HUD image will appear straight ahead near the front bumper.
When the ignition key is turned
to RUN, all possible
HUD images will come on. Then the Head-Up Display
will operate normally.
NOTICE:
Although the HUD image appears to be near the
front
of the vehicle, do not use it as a parking aid.
The
HUD was not designed for that purpose. If
you try to use it that way, such as in a parking
lot, you may misjudge distance and run into
something.

Air Conditioning Heating
On very hot days, open the
windows long enough to
let hot inside air escape. This reduces the time the
compressor has
to run, which should help fuel economy.
For quick cool-down on very hot days,
use MAX with
the temperature knob all the way in the blue area.
If this
setting is used for long periods
of time, the air in your
vehicle may become too dry.
For normal cooling on hot days, use
VENT with the
temperature hob in the blue area and the
A/C button
pushed
in. The system will bring in outside air and cool it.
On cool but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.
You can use BI-LEVEL with the temperature knob in
the middle and the
A/C button pushed in. The system
will bring in outside air and direct it to your upper body,
while sending slightly warmed air to your lower body.
You may notice this temperature difference more at
some times than others. On
cold days use
FLOOR with the temperature knob all
the way in the red area. The system will bring in outside
air, heat
it and send it to the floor ducts.
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm
air faster when it’s
cold outside (0°F (-lS0C) or lower).
An engine coolant
heater warms the coolant your engine and heating
system use to provide heat. See “Engine Coolant
Heater” in the Index.
Ventilation
For mild outside temperatures when little heating or
cooling is needed, use VENT
to direct outside air
through your vehicle. Your vehicle also has the
flow-through ventilation system described later in this
section.
Defogging and Defrosting Windows
Your system has two settings for clearing the front and
side windows. To defrost the windows quickly, use
DEFROST with the temperature knob all the way in the
red area. To warm passengers while keeping the
windows clean, use DEFOG.

Engine Overheating
You will find a coolant temperature gage and a warning
light about a hot engine on your instrument panel. See
“Engine Coolant Temperature Gage” and “Engine
Coolant Temperature Warning Light” in the Index. You
also have a low coolant light on your instrument panel.
See “Low Coolant Light” in the Index.
If Steam Is Coming From Your 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.
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.

Engine Coolant Heater
An engine coolant heater can be a big help if you have
to park outside in very cold weather,
0°F (-18°C) or
colder. If your vehicle has
this option, see “Engine
Coolant Heater” in the Index.
What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don’t let used oil stay on your skin
for very long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly throw
away clothing or rags containing used engine oil. (See
the manufacturer’s warnings about the use and disposal
of oil products.)
Used oil can be a real threat to the environment.
If you
change your own oil, be sure to drain all free-flowing oil
from the filter before disposal. Don’t ever dispose of oil
by putting
it in the trash, pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle it by taking it to a place that collects used oil.
If
you have a problem properly disposing of your used oil,
ask your dealer, a service station
or a local recycling
center for help.

Engine Coolant
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
radiator, see “Engine Overheating” in the Index.
The proper coolant for your Pontiac will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 262°F (128 “C).
0 Protect against rust and corrosion.
Help keep the proper engine temperature.
0 Let the warning lights work as they should.
What to Use
Use a mixture of one-half
clean water (preferably
distilled) and one-half antifreeze that meets “GM Specification 1825-M,” which won’t damage aluminum
parts. You can also use a recycled coolant conforming to
GM Specification 1825-M with
a complete coolant flush
and refill. Use GM Engine Coolant Supplement (sealer)
with any complete coolant flush and refill.
If you use
this mixture, you don’t need to add anything else.
I 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.

Radiator Pressure Cap
NOTICE:
Your radiator 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. Be sure the arrows
on
the cap line up with the overflow tube on the
radiator filler neck.
When you replace your radiator pressure cap, an A@
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.
When you replace your thermostat, an
AC@ thermostat
is recommended.
Power Steering Fluid
3.1L L82 (Code M) Engine 3.4L LQl (Code X) Engine
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.
