1998 CHEVROLET PRIZM heater

Downloaded from www.Manualslib.com manuals search engine Bi-Level
You may want to use bi-level heating on cool, but sunny
days. This setting directs outside air toward your body
and warmer air toward your feet.
Move the air intake lever to CIRCULATE and turn the
airflow knob
to BI-LEVEL. Turn the temperature knob
to the white area and the fan knob toward
HI.
Ventilation System
For mild outside temperatures, when very little heating
is required,
you can still direct outside air through
your vehicle.
Move the air intake lever to CIRCULATE and turn the
airflow knob
to VENT. Turn the temperature knob to a
comfortable setting and the fan knob toward
HI.
Airflow through the side vents is normal in all airflow
modes.
To optimize the effectiveness of your system in
FLOOR, DEFOG, or DEFROST modes, turn
the
outboard vent (shut-off) thumbwheels down to the
closed position.
Your vehicle's flow-through ventilation system
supplies outside air into the vehicle when it
is moving.
Outside air will also enter the vehicle when the heater or
the air conditioning fan is running and
the air intake
lever is at CIRCULATE. Adjust the direction
of airflow
by moving the
louvered vents.
Ventilation Tips
Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging
the inside of your windows.

Downloaded from www.Manualslib.com manuals search engine Run your engine only as long as you must. This saves
fuel. When you
run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that
you get and it keeps the
battery charged. You will need a well-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlamps. Let the heater run for a while.
Then, shut the engine
off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But
do it as little as possible. Preserve the
fuel as long as you can.
To help keep warm, you can get
out
of the vehicle and do some fairly vigorous exercises
every half hour or
so until help comes.
Loading Your Vehicle
VEHICLE CAPACITY WEIGHT
RECOMMENDED TIRE SIZE
SEE OWNER'S MANUAL FOR ADDITIONAL INFORMATION
Two labels on your vehicle show how much weight it
may properly carry. The Tire-Loading Information label
found in the glove compartment tells you the proper
size, speed rating and recommended inflation pressures
for the tires on your vehicle. It also gives you important
information about the number
of people that can be in
your vehicle and the total weight that you can carry.
This weight is called the Vehicle Capacity Weight and
includes the weight
of all occupants, cargo and all
nonfactory-installed options.

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:
0 Climb a long hill on a hot day.
0 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. If you have an air conditioner, turn it off.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- DRIVE (D) for automatic transaxles. 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 minutes 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.
You may decide not to lift the hood but to get service
help right away.

wnen you decide it’s safe to lift the hood, here’s what
you’ll
see:
A. Electric Engine Cooling Fans
B. Radiator Pressure Cap
C. Coolant Recovery Tank
An electric engine cooling fan under the hood can
start up even when the engine
is not running and
can injure you. Keep hands, clothing and tools
away from any underhood electric 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.
5-16

Downloaded from www.Manualslib.com manuals search engine A CAUTION:
Heater and radiator hoses, and other engine
parts, can be
very hot. Don’t touch them. If you
do, you can be burned.
Don’t run the engine if there is a leak.
If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
NOTICE:
Engine damage from running your engine
without coolant isn’t covered by your warranty.
If there seems to be no leak, with the engine on, check to
see if the electric engine cooling fans
are running. If the
engine is overheating, both
fans should be running. If
they aren’t, your vehicle needs service.
How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the coolant
level isn’t at
FULL, add a 50/50 mixture of clean water
(preferably distilled) and a proper coolant at the coolant
recovery tank. (See “Engine Coolant” in the Index for
more information about the proper coolant mixture.)
/! CAUTION:
I
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 mixture will. Your vehicle’s coolant
warning system is set for the proper coolant
mixture. With plain water or the wrong mixture,
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 mixture of clean water and a
proper coolant.
5-17

Downloaded from www.Manualslib.com manuals search engine NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mixture. You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it
will burn if the engine parts are hot
enough. Don’t spill coolant on a hot engine.
When the coolant in the coolant recovery tank is at
FULL start your vehicle.
If the overheat warning continues, there’s one more
thing
you can try. You can add the proper coolant
mixture directly to the radiator, but
be sure the
cooling system is cool before you do it.
5-18

Downloaded from www.Manualslib.com manuals search engine NOTICE:
If you use an improper coolant mixture, your
engine could overheat and be badly damaged.
The repair cost wouldn’t be covered
by your
warranty. Too much water in the mixture can
freeze and crack the engine, radiator, heater
core and other parts.
If you have to add coolant more than four times a year,
lave
your dealer check your cooling system.
I NOTICE:
If you use the proper coolant, you don’t have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.
Checking Coolant
When your engine is cold,
the coolant level should be
at
LOW, or a little higher.
When your engine is warm,
the level should be up to
FULL, or a little higher.
Adding Coolant
If you need more coolant, add the proper coolant
mixture
at the coolant recovery tank, but be careful not
to spill it.
