1996 CHEVROLET EXPRESS heater

Downloaded from www.Manualslib.com manuals search engine Engine Coolant Heater (Option)
-
In very cold weather, 0°F (- 1 SOC) 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 AC outlet.
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 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.

to move by rotating the
switch counterclockwise to
adjust the passenger side
mirror and clockwise to
adjust the driver side
mirror. The center position
is neutral.
Then, adjust the mirror angle by pressing the outer
arrows on the switch until the mirror is adjusted
where
you want it.
Your electric outside
rearview mirrors can be
defrosted by pressing the
switch next to the heater
controls. (See “Comfort
Controls” in the Index.)
Convex Outside .Mirror
Your passenger’s side mirror is convex. A convex
mirror’s surface
is curved so you can see more from the
driver’s seat.
CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder before
changing lanes.

In this section you’ll find out how to operate the comfort Heater Controls
control and audio systems offered with your vehicle. Be
sure to read about the particular systems supplied with
your vehicle.
Comfort Controls
This section tells you how to make your air system work
for you. Your comfort control system uses
ozone-friendly
R- 134a refrigerant.
With these systems, you can control the heating,
cooling and ventilation in your van. Your vehicle also
has a flow-through ventilation system described later in
this section. If your vehicle does not have air conditioning, your
heater controls will
look like this.

The knob on the left side of the heating system control
panel controls the fan speed. The knob has four speed
positions. To increase airflow, move the knob toward
HI. To decrease airflow, move it toward LO. To turn the
fan off, move the knob to OFF.
Temperature
Knob
The middle knob lets you select the relative temperature
of the air flowing into the passenger area of your
vehicle. This knob will allow
you to adjust the relative

If you have a rear heater (without rear air conditioning),
the control switch
is located on the instrument panel.
To increase and decrease the flow of heated air to the
rear floor vents, move the switch marked
REAR HEAT
to the blower speed you want.
The knob has three speed positions.
To increase the flow
of heated air, move the switch toward HIGH. To turn the
fan
off, move the switch to OFF.
Rear Air Conditioning and Rear Heater
If your vehicle has a rear air conditioning and rear heater
system combination, controls are provided to regulate the
temperature, location
and speed of the air flow.
Front Passenger Control
To adjust the air temperature, turn the temperature knob
on the right side of the control panel.
For warmer air, turn the knob clockwise toward the red
area, and for cooler air, turn the knob counterclockwise
toward the blue area.

Downloaded from www.Manualslib.com manuals search engine Air Conditioning
Before using your vehicle’s air conditioning, open the
windows to clear the vehicle of hot air. This reduces the
time
it takes for your vehicle to cool down. Then keep
your windows closed for the air conditioner
to work at
its best.
You can use MAX A/C with the temperature knob in the
blue area, when it’s really hot outside and you need to
cool the inside air quickly. MAX A/C lets in only a little
air from the outside.
If you first use
MAX A/C, you can then use A/C with
the temperature knob
in the blue area, as soon as the
vehicle has cooled down,
so outside air will be going
through your vehicle.
If your vehicle has rear air conditioning, setting it on LO
may enhance front A/C performance by allowing
trapped refrigerant
in rear lines to circulate.
When the air conditioning, DEFROST or
BLEND is on,
you may notice a slight increase or decrease in engine
speed, due
to compressor operation. This is normal
because the system is designed
to cycle the compressor
on and off to keep the desired temperature.
Heating
On cold days, use HEATER with the temperature knob
in the red area. Outside air will be brought in through
the floor outlets. The heater works best if
you keep your
windows closed while using
it.
If you use the optional engine coolant heater before
starting your engine, your heating system will produce
warmer air ftdster to heat the passenger compartment in
cold weather. See “Engine Coolant Heater” in the Index.
