(Option) -
1. Engine Coolant Heater Strap
2. Engine Coolant
Heater Cap
In very cold weather,
0°F (-1 8 "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.
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 1 10-volt outlet.
A CAUTION:
NOTICE:
After you've used the coolant heater, be sure to store the co\
rd as
it was before to keep it away from moving engine parts. If you
don't,
it could be damaged.

Downloaded from www.Manualslib.com manuals search engine How long should you keep the coolant heater plugged in? The answer
depends on the weather, the kind
of oil you have, and some other things.
Instead of trying to list everything here, we ask that you contact a
GM
dealer in the area where you’ll be parking your vehicle. The dealer can give
you the best advice for
that particular area.
Automatic Transmission
There are several
different positions for
your shift lever.
P (Park) - This locks your rear wheels. It’s the best position to use
when you start your engine because your vehicle can’t move easily.

Damage to your engine from neglected oil problems can be
costly and

Engine Coolant Temperature Gage
Standard Cluster
If you have the Standard Cluster, you have a gage that shows the engine
coolant temperature.
If the gage pointer moves to the “H” (red) side, your
engine
is too hot!
It means that your engine coolant has overheated. If you have been
operating your vehicle under normal driving conditions, you shou\
ld pull
off
the road, stop your vehicle and turn off the engine as soon as possible.
If you have a digital cluster, a box around the temperature symbol will also
flash when your engine is too hot.

In “Problems on the Road,” this manual shows what to do. See “Engine
Overheating” in the Index.
Voltmeter
Standard Cluster Digital Cluster
When your engine is not running, but the ignition is on (in the RUN
position), the gage shows your battery’s state of charge in DC volts. When
the ignition is running, the gage shows the condition of the charging system.
Readings between the low and high warning zones indicate the n\
ormal
operating range.
Readings
in either warning zone indicate a possible problem in the electrical
system.
On the digital cluster, a box around the voltmeter symbol will begin the
flash when the charging system needs service.
You can only drive for a short time with the readings in either warning zone.
If you must drive, turn off all unnecessary accessories.

If you use the optional engine coolant heater before starting your engine,
your heating system will produce warmer air faster to heat the passenger
compartment in cold weather. See “Engine Coolant Heater” in the Index.
Audio Systems
Your Delco@ audio system has been designed to operate easily and give
years
of listening pleasure. But you will get the most enjoyment out of it, if
you acquaint yourself
with it first. Find out what your Delco@ system can
do and how to operate all its controls, to be sure you’re getting the most out
of
the advanced engineering that went into it.
Be aware that hearing damage from loud noise is almost undetectable until
it is too late. Your hearing can adapt to higher volumes of sound. Sound that
seems normal can be loud and harmful to your hearing. Take precautions by
adjusting the volume control on your radio to a safe sound level before your
hearing adapts to it.
To help avoid hearing loss or damage:
0 Adjust the volume control to the lowest setting.
Increase volume slowly until you hear comfortably and clearly.
FM Stereo
FM stereo will give you the best sound. But FM signals will reach only
about
10 to 40 miles (16 to 65 km). Tall buildings or hills can interfere with
FM signals, causing the sound to come and go.
The range for most AM stations is greater than for FM, especially at night.
The longer range, however, can cause stations to interfere
with each other.
AM can pick up noise from things like storms and power lines. Try reducing
the treble to reduce this noise
if you ever get it.
AM Stereo
This means the Delco@ system can receive C-QUAM@ stereo broadcasts.
Many AM stations around the country use C-QUAM@ to produce stereo,
though some do not. (C-QUAM@ is
a registered trademark of Motorola,
Inc.) If your Delco@ system can get C-QUAM@, your
“STEREO” light will
come on
when you’re receiving it.

Here are some tips for winter driving:
Have your vehicle in good shape for winter. Be sure your engine
coolant
mix is correct.
You may want to put winter emergency supplies in your vehicle.
Include an ice scraper, a small brush or broom, a supply of windshield
washer fluid, a rag, some winter outer clothing,
a small shovel, a flashlight,
a red cloth, and a couple
of reflective warning triangles. And, if you will be
driving under severe conditions, include a small bag of sand, a piece of old
carpet or a couple of burlap bags to help provide traction. Be sure you
properly secure these items in your vehicle.
Driving on Snow or Ice
Most of the time, those places where your tires meet the road probably have
good traction.
However, if there is snow or ice between your tires and the road, you can
have a very slippery situation. You’ll have a lot less traction or “grip” and
will need to be very careful.

If Steam Is Coming From Your Enaine
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.
5-11

Downloaded from www.Manualslib.com manuals search engine When you decide it’s safe to lift the hood, here’s what you’ll see:
A. Coolant recovery tank
B. Radiator pressure cap
C. Engine fan
If the coolant inside the coolant recovery tank is boiling, don’t do anything
else until it cools down.
The
coolant level should be at or above FULL. 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.
NOTICE:
Engine damage from running your engine without coolant isn’t \
covered by your warranty.
If there seems to be no leak, start the engine again. See if the fan speed
increases when idle speed
is doubled by pushing the accelerator pedal down.
If it doesn’t, your vehicle needs service. Turn
off the engine.
