1998 CHEVROLET BLAZER coolant level

Downloaded from www.Manualslib.com manuals search engine 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 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 Operation
Your automatic transmission may have a shift lever
located on the console between the seats
or on the
steering column.
There
are several different positions for your shift lever.
If your vehicle is equipped with a column shift lever, it
features an electronic shift position indicator within the
instrument cluster. This display must be powered
anytime the shift lever is capable
of being moved out of
PARK (P). This means that if your key is in OFF, but
not locked, there will be
a small current drain on your
battery which could discharge your battery over a period
of time. If you need to leave your key in the ignition in
OFF for an extended period, it is recommended that you
disconnect the battery cable from the battery to prevent
discharging your battery. PARK
(P): This
locks your rear wheels. It’s the best
position to use when you start your engine because your
vehicle can’t move easily.
It is dangerous to get out of your vehicle if the
shift lever is
not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don’t leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You
or others could be injured. To be sure your
vehicle won’t move, even when you’re on
fairly
level ground, always set your parking brake and
move the shift lever to PARK
(P).
See “Shifting Into PARK (P)” in the Index. If
you’re pulling a trailer, see “Towing a nailer’’ in
the Index.

Downloaded from www.Manualslib.com manuals search engine With the automatic setting, the air conditioning
compressor automatically cycles when needed to cool
the air. In cold weather, when the system senses the need
for heat, the airflow will be directed out the floor
outlets.
As the interior temperature approaches a desired
setting, the blower speed will decrease. To maintain
interior comfort, the airflow will adjust between the
instrument panel air outlets and floor outlets. On bright
sunny days in cool weather, the airflow may come out of
the air conditioning and floor outlets (bi-level mode) to
maintain comfort and prevent stuffiness.
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 your vehicle
is sitting out on a warm day and you
have the fan set
on AUTO, the air will first flow out of
the floor air outlets for a few seconds. 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. Be careful
not to put anything over the solar sensor
located around the center of the instrument panel.
This sensor is used by the automatic system to
regulate temperature.
Mode Knob - Manual Operation
The right knob on the control panel allows you to
choose the direction of air delivery.
You can choose to set the climate control system
operations yourself, or let the system work for
you
by placing the system in AUTO mode. See “Mode
Knob
- Automatic Operation” earlier in this section.
+.
fl PANEL: This setting directs most of the air
through the instrument panel outlets and a small amount
through the floor outlets.
+H BI-LEVEL: Air is delivered through the heater
floor outlets as well as the instrument panel outlets.
+’ HEATER: This setting directs most of the
warmed air through the heater floor outlets and some
air through the windshield defroster outlets.

On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for your
vehicle
to cool down. Then keep your windows closed
for the air conditioner to work its best.
For quick cool-down on very hot days, use MAX A/C
with the temperature knob turned to the left. This setting
should be used to keep odors and/or dust from entering
the vehicle. For normal cooling
on hot days, use A/C
with the temperature knob turned to the left.
On vehicles equipped with the Electronic Climate
Control system, this same performance can be achieved
as long as the A/C is enabled and the outside air button
is not active.
Heating
On cool but sunny days, use BI-LEVEL A/C to deliver
warm air to the
floor and cooler air to the instrument
panel outlets.
When the air conditioner is on, you may sometimes
notice slight changes in your vehicle’s engine speed and
power. This is normal because the system is designed
to cycle the compressor on and off to keep the
desired temperature.
The heater works best if you keep your windows closed
while using it. On cold days,
use HEATER with the
temperature knob turned
to the right. BLEND is useful
in cool weather when
you have fog or ice on the
windshield or side windows.
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.
Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use
VENT to direct outside air
through your vehicle. Airflow is through the instrument
panel outlets.
Your vehicle’s ventilation system supplies outside air to
the inside
of your vehicle when it is moving. When the
vehicle is
not moving, you can get outside air to flow
through by selecting any mode and any fan speed.

Downloaded from www.Manualslib.com manuals search engine If you have an automatic transmission, you should use
DRIVE
(D) when towing a trailer. Operating your
vehicle in DRIVE (D) when towing a trailer will
minimize heat buildup and extend the life
of your
transmission. Or, if
you have a manual transmission,
it’s better not to use
FIFTH (5) gear, just drive in
FOURTH
(4) gear (or, as you need to, a lower gear).
When towing at high altitude on steep uphill grades,
consider the following: Engine coolant will boil at a
lower temperature than at normal altitudes. If
you turn
your engine off immediately after towing at high altitude
on steep uphill grades, your vehicle may show signs
similar to engine overheating.
To avoid this, let the
engine run while parked (preferably
on level ground)
with the automatic transmission in PARK (P) (or the
manual transmission out
of gear and the parking brake
applied) for a few minutes before turning the engine
off.
If you do get the overheat warning, see “Engine
Overheating” in the Index.
Parking on Hills
You really should not park your vehicle, with a trailer
attached,
on a hill. If something goes wrong, your rig
could start
to move. People can be injured, and both
your vehicle and the trailer can be damaged. But if you ever have
to park your rig
on a hill, here’s
how
to do it:
1.
2.
3.
4.
5.
6.
Apply your regular brakes, but don’t shift into
PARK
(P) yet, or into gear for a manual
transmission. Then turn your wheels into the curb if
facing downhill or into traffic if facing uphill.
Have someone place chocks under the trailer wheels.
When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
Reapply the regular brakes. Then apply your
parking brake, and then shift into PARK (P), or
REVERSE
(R) for a manual transmission.
If
you have a four-wheel-drive vehicle with a
manual transfer case shift lever, be sure the transfer
case is
in a drive gear -- not in NEUTRAL (N).
Release the regular brakes.
When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
0 Start your engine;
0 Shift into a gear; and
0 R.elease the parking brake.

Downloaded from www.Manualslib.com manuals search engine When you decide it’s safe to lift the hood, here’s what
you’ll see:
The coolant level should be at least up to the
ADD mark. i
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.
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.
5-14

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, start the engine again. See
if the engine cooling 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.
How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at the
ADD mark, add a 50/50 mixture of clean
water (preferably distilled) and DEX-COOL@ engine
coolant at the coolant recovery tank. (See “Engine
Coolant” in the Index for more information.)
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
50EO mixture of clean water and
DEX-COOL@ coolant.

5. Put the cap back on the coolant recovery tank, but
leave the pressure cap off.
6.
7.
Start the engine and let it run until you can feel the
upper radiator hose getting hot. Watch out for the
engine cooling fan.
By this time, the coolant level inside the radiator
filler neck may be lower. If the level is lower, add
more of the proper
DEX-COOL@ coolant mixture
through the filler neck
until the level reaches the
base
of the filler neck.
