engine CHEVROLET TRACKER 1993 Workshop Manual

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.

Problems on the Road
c
Engine damage from running yollr I
engine without coolant isn’t
covered by your warranty.
I
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.

you turn the radiator pressure cap
- even a little - they can come
out at high speed. Never turn
the
cap when the cooling system,
including the radiator pressure cap,
is hot. Wait for the cooling system
and radiator pressure cap to cool

4. Then fill the coolant recovery tank to
the
FULL mark.
5. Put the cap back on the coolant
recovery tank, but leave the radiator
pressure cap
off.
6. Start the engine and let it run until
you can feel the upper radiator hose
getting
hot. Watch out for the engine
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 mix through the filler neck until the level reaches the base of the
filler neck.

CAUTION
A
Changing a tire can cause an injury. The vehicle can slip off the jack
and roll over you or other people. You and they could be badly injured.
Find a level place to change your tire.
To help prevent the vehicle from
moving:
1. Set the parking brake firmly.
2. Put the shift lever in P (Park).
3. Shift a manual transmission to 1 (First) or R (Reverse).
4. If you have a four-wheel-drive vehicle, be sure the transfer case is in a
5. Turn off the engine.
To be even more certain the vehicle won’t move, you can put chocks at the
front and rear of the tire farthest away from the one being changed. That
would be the tire on the other side of the vehicle, at the opposite end.

- not in N (Neutral).
I The following steps will tell
you how to use the jack and change a tire. The
equipment you’ll need
is under the
front seats.
The jack and wheel wrench are under
the passenger’s seat.

If You’re Stuck: In
Sand, Mud, Ice or
Snow
What you don’t want to do when your
vehicle is stuck is to spin your wheels.
The method known as “rocking” can
help you get out when you’re stuck, but
you must use caution.
‘ If you let your tires spin at
42 high speed, they can explode
and you or others could be injured.
And, the transmission and other
parts
of the vehicle can overheat.
That could cause
an engine
compartment fire or other damage.
When you’re stuck, spin the
wheels as little
as possible. Don’t
spin the wheels above
35 mph
(55 km/h) as shown on the
speedometer. Spinning
your wheels can destroy
parts of your vehicle as well as th
tires. If you spin the wheels too
fast while shifting your
transmission
back and forth, you
can destroy your transmission.

I NOTICE
r
Fuel
Use regular unleaded gasoline rated at
87 octane or higher. It should meet
specifications, ASTM
D4814 in the U.S.
and CGSB 3.5-M92 in Canada. These
fuels should have the proper additives,
so you should not have to add anything
to the fuel.
In the U.S. and Canada, it’s easy to be
sure you get the right kind of gasoline
(unleaded). You’ll see
UNLEADED
right on the pump. And only unleaded
nozzles will fit into your vehicle’s filler
neck.
Be sure the posted octane is at least
87.
If the octane is less than 87, you may
get a heavy knocking noise when you drive.
If it’s bad enough, it can damage
your engine.
If you’re using fuel rated at
87 octane or
higher and you still hear heavy
knocking, your engine needs service.
But don’t worry if you hear a little
pinging noise when you’re accelerating or driving up a
hill. That’s normal, and
you don’t have to buy a higher octane
fuel to get rid of pinging. It’s the heavy,
constant knock that means you have a
problem.
What about gasoline with blending materials that contain oxygen, such as
MTBE or alcohol?

Gasolines for Cleaner Air
Your use of gasoline with detergent
additives will help prevent deposits from
forming in your engine and fuel system.
That helps keep your engine in tune and your emission control system working
properly. It’s
good for your vehicle, and
you’ll be doing your part for cleaner air.
Many gasolines are now blended with
materials called oxygenates. General
Motors recommends that you use
gasolines
with these blending materials,
such as MTBE and ethanol.
By doing
so, you can help clean the air, especially
in those parts of the country that have
high carbon monoxide levels.
ProCarManuals.com

In addition, some gasoline suppliers are
now producing reformulated gasolines.
These gasolines are specially designed to
reduce vehicle emissions. General
Motors recommends that you use
reformulated gasoline. By doing
so, you
can help clean the air, especially in
those parts of the country that have high
ozone levels,
You should ask your service station
operators
if their gasolines contain
detergents and oxygenates, and if they
have been reformulated
to reduce
vehicle emissions.
Fuels in Foreign Countries
If you plan on driving in another
country outside the
U.S. or Canada,
unleaded fuel may be hard to find.
Do
not use leaded gasoline. If you use even
one tankful, your emission controls
won’t work well or at
all. With
continuous use, spark plugs can get
fouled, the exhaust system can corrode,
and your engine oil
can deteriorate
quickly. Your vehicle’s oxygen sensor
will be damaged. All of that means costly repairs that wouldn’t be covered
by your warranty.
To check on fuel availability, ask an
auto club, or contact a major oil company that does business in
the
country where you’ll be
driving.
You can also write us at the following
address for advice. Just tell us where
you’re going and give your Vehicle
Identification Number
(VIN).
