engine CHEVROLET TRACKER 1997 Workshop Manual

Using a match near a battery can cause battery
gas to explode. People have been hurt doing this,
and some have been blinded. Use a flashlight
if
you need more light.
Be sure the battery has enough water. You don’t
need to add water to the Delco Freedom@ battery
installed in every new
GM vehicle. But if a
battery has filler caps, be sure the right amount
of
fluid is there. If it is low, add water to take care
of that first. If you don’t, explosive gas could
be present.
Battery fluid contains acid that can burn you.
Don’t get
it on you. If you accidentally get it in
your eyes or
on your skin, flush the place with
water and get medical help immediately.
5. Check that the jumper cables don’t have loose or
missing insulation. If they do, you could get a shock.
The vehicles could be damaged, too.
A CAUTION:
-
Fans or other moving engine parts can injure you
badly. Keep your hands away from moving parts
once the engine is running.

6. Positive (+) goes to positive (+) and negative (-)
goes to negative (-) or a metal engine part. Don’t
connect positive
(+) to negative (-) or you’ll get a
short that would damage the battery and maybe other
parts, too. Connect the red positive
(+) cable to the
positive
(+) terminal of the vehicle with the dead
battery.
Use a remote positive (+) terminal if the
vehicle has one.

touch metal. Connect it
to the positive

terminal of the good
battery. Use a remote
positive
(+) terminal if
the vehicle has one.

black negative
(-) cable
to the
good battery’s
negative
(-) terminal.
Don’t let the other end
touch anything until the
next step.

9. The other end of the negative (-) cable doesn’t go
to the dead battery. It goes to a heavy unpainted
metal part on the engine of the vehicle with the
dead battery. Attach the cable at least
18 inches (45
cm) away from the dead battery, but not near
engine parts that move. The electrical connection is
just as good there, but the chance
of sparks getting
back to the battery is much less.

Engine Overheating
You will find a coolant temperature gage on your Geo
instrument panel.
If Steam Is Coming From Your Engine
Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay
away
from the engine if you see or hear steam coming
from it. Just turn it off and get everyone
away
from the vehicle until it cools down. Wait until
there is no sign of steam or coolant before you
open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch fire. You or
others could be badly burned. Stop your engine if
it overheats, and get out of the vehicle until the
engine is cool.
I NOTICE:
~~~~ ~ ~~
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be
covered by your warranty.

If No Steam Is Coming From Your Engine
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 --AUTOMATIC OVERDRIVE
0 or
DRIVE (D) for automatic transmissions.
Ii‘ 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.

When you decide it’s safe to lift the hood, here‘s what
you’ll see:
A. Radiator Pressure Cap
B. Electric Engine Fan
C. Coolant Recovery Tank

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.
I
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.
I 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 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 the
FULL mark, 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
mix.)
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 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 coolant.
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 mix.

/ CAUTION:
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 or
above the
FULL mark, start your vehicle.
If the overheat warning continues, there's one more
thing you can try.
You can add the proper coolant mix
directly
to the radiator, but be sure the cooling system is
cool before you do it.

If the level is lower, add
more of
the proper coolant mixture through the
filler neck until the level reaches the base of the

this procedure
if coolant begins to flow out of the
