cooling CHEVROLET TRACKER 1993 User Guide

When you decide it’s safe to lift the
hood, here’s what you’ll see:
1. Coolant Recovery Tank
2. Radiator Pressure Cap
3. Electric Engine Fan
A An electric fan under the
hood can start up even when
thL @ne is not running and can
injure you. Keep hands, clothing
and tools away from any
underhood electric fan.
Don’t reach through the grille to
release the underhood lever.
- II E I L
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.
unu I lVlV
Heater and radiator hoses,
1 L 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.

If there seems to be no leak, check to
see if the electric engine fan
is running.
If
the engine is overheating, the fan
should be running. If it isn’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 or above
FULL, add a 50/50 mixture of clean
water
(preferably distilled) and the
proper antifreeze at the coolant recovery
tank. (See “Engine Coolant”
in the
Index for more information about the
proper coolant mix.)
A Adding only plain water to
L your cooling system can be
dangerous. Plain water, or some
other liquid, like alcohol, can boil
before the proper coolant mix will.
Your vehicle’s coolant warning
system is set for the proper coolant
mix. With plain water, or the
wrong mix, 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 mix
of clean water and a proper
antifreeze.

How to Add Coolant to the Radiator
1. You can remove the radiator pressure
cap when the cooling system,
including the radiator pressure cap
and upper radiator hose, is no longer
hot. Turn the pressure cap slowly
to
the left until it first stops. (Don't
press down while turning the
pressure cap.)
If you hear a hiss, wait for that to
stop. A hiss means there is still some
pressure
left.
2. Then keep turning the pressure cap,
but now push down as you turn
it.
Remove the pressure cap.

3. Fill the radiator with the proper mix,

How to Check Lubricant:
If the level is below the bottom of the
filler plug hole, you’ll need to add some
lubricant.
If the differential is at operating
temperature (warm), add enough
lubricant to raise the level to the bottom
of the filler plug hole.
If the differential
is cold, add enough
lubricant to raise the level to
1/2 inch
(12 mm) below the filler plug hole.
What to Use:
Refer to the Maintenance Schedule to
determine what kind of lubricant to use.
See “Recommended Fluids and
Lubricants” in the Index.
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, see “Engine
Overheating” in the Index.

What to Use:
Use a mixture of one-half clean water
(preferably distilled) and one-half
antifreeze or approved recycled coolant
that meets “GM Specification 6038M,”
which won’t damage aluminum parts.
Also use GM Engine Coolant
Supplement (sealer) with a complete

Engine Oil and Filter Change* - Always use SG
Energy Conserving I1 Oils of proper viscosity. The
SG designation may be shown alone or in
combination with others, such as SG/CC, SG/CD,
or SF, SG, CC, etc. To determine the preferred
viscosity for your vehicle’s engine (e.g., SAE
5W-30 or 1OW-30) see “Engine Oil’’ in the Index.
Engine Idle Speed Check* - Check the idle speed
and adjust it to underhood label specifications.
*An Emission Control Service.
The proper fluids and lubricants to use are listed in Section
D. Make sure whoever services your vehicle uses these. All
parts should be replaced and all necessary repairs done
before

3 Cooling System Service* - Drain, flush and refill
the system with new or approved recycled coolant
conforming to
GM Specification 4038M. Keep
coolant at
the proper mixture as specified. See
“Coolant”
in the Index. This provides proper freeze
protection, corrosion inhibitor level, and engine
operating temperature.
Inspect hoses and replace
if they are cracked,
swollen, or deteriorated. Tighten screw-type hose
clamps. Clean the outside of the radiator and air
conditioning condenser. Wash
the pressure cap and
neck.
To help ensure proper operation, we recommend a
pressure test of both
the cooling system and the
pressure cap.
