2004 CHEVROLET TRACKER maintenance

3. Check both sides of the dipstick, and read the lower
level. The ¯uid level must be in the COLD area for
a cold check or in the HOT area for a hot check.
4. If the ¯uid level is in the acceptable range, push the
dipstick back in all the way.
How to Add Fluid
Refer to the Maintenance Schedule to determine
what kind of transmission ¯uid to use. See
Part D: Recommended Fluids and Lubricants on
page 6-30.
Add ¯uid only after checking the transmission ¯uid while
it is hot. (A cold check is used only as a reference.) If
the ¯uid level is low, add only enough of the proper ¯uid
to bring the level up to the HOT area for a hot check.
It doesn't take much ¯uid, generally less than 0.6 pints
(0.3 L).
Don't over®ll.
Notice:
We recommend you use only ¯uid labeled
DEXRONž-III, because ¯uid with that label is
made especially for your automatic transmission.
Damage caused by ¯uid other than DEXRON
ž-III is
not covered by your new vehicle warranty.
·After adding ¯uid, recheck the ¯uid level as
described under ªHow to Check.º
·When the correct ¯uid level is obtained, push the
dipstick back in all the way.

Manual Transmission Fluid
When to Check and Change
A good time to have it checked is when the engine oil is
changed. Refer to the Maintenance Schedule to
determine when to change your transmission ¯uid. See
Part A: Scheduled Maintenance Services on page 6-4.
How to Check
Because this operation can be a little difficult, you may
choose to have this done at your Chevrolet dealership
service department.
If you do it yourself, be sure to follow all the instructions
here, or you could get a false reading.
Notice:Too much or too little ¯uid can damage
your transmission. Too much can mean that some
of the ¯uid could come out and fall on hot engine
part or exhaust system parts, starting a ®re.
Too little ¯uid could cause the transmission to
overheat. Be sure to get an accurate reading if you
check your transmission ¯uid.Check the ¯uid level only when your engine is off, the
vehicle is parked on a level place and the transmission
is cool enough for you to rest your ®ngers on the
transmission case.
Then, follow these steps:
1. Remove the ®ller plug.
2. Check that the lubricant level is up to the bottom of
the ®ller plug hole.
3. If the ¯uid level is good, install the plug and be sure
it is fully seated. If the ¯uid level is low, add more
¯uid as described in the next steps.
5-23

How to Add Fluid
Here's how to add ¯uid. Refer to the Maintenance
Schedule to determine what kind of ¯uid to use. See
Part D: Recommended Fluids and Lubricants on
page 6-30.
1. Remove the ®ller plug.
2. Remove the drain plug, drain the ¯uid and reinstall
the drain plug.
3. Add ¯uid at the ®ller plug hole. Add only enough
¯uid to bring the ¯uid level up to the bottom of the
®ller plug hole.
4. Reinstall the ®ller plug. Be sure the plug is fully
seated.
Hydraulic Clutch
It is not necessary to regularly check clutch ¯uid unless
you suspect there is a leak in the system. Adding
¯uid won't correct a leak.
A ¯uid loss in this system could indicate a problem.
Have the system inspected and repaired.
When to Check and What to Use
Refer to the Maintenance Schedule to determine how
often you should check the ¯uid level in your clutch
master cylinder reservoir and for the proper ¯uid. See
Part B: Owner Checks and Services on page 6-24andPart D: Recommended Fluids and Lubricants on
page 6-30.

Brakes
Brake Fluid
Your brake master cylinder reservoir is ®lled with DOT-3
brake ¯uid. SeeEngine Compartment Overview on
page 5-12for the location of the reservoir.
There are only two reasons why the brake ¯uid level in
the reservoir might go down. The ®rst is that the
brake ¯uid goes down to an acceptable level during
normal brake lining wear. When new linings are put in,
the ¯uid level goes back up. The other reason is
that ¯uid is leaking out of the brake system.If it is, you should have your brake system ®xed, since a
leak means that sooner or later your brakes will not
work well, or will not work at all.
So, it is not a good idea to ªtop offº your brake ¯uid.
Adding brake ¯uid will not correct a leak. If you add ¯uid
when your linings are worn, then you will have too
much ¯uid when you get new brake linings. You should
add (or remove) brake ¯uid, as necessary, only when
work is done on the brake hydraulic system.
{CAUTION:
If you have too much brake ¯uid, it can spill on
the engine. The ¯uid will burn if the engine is
hot enough. You or others could be burned,
and your vehicle could be damaged. Add brake
¯uid only when work is done on the brake
hydraulic system. See ªChecking Brake Fluidº
in this section.
Refer to the Maintenance Schedule to determine when
to check your brake ¯uid. See
Part C: Periodic
Maintenance Inspections on page 6-28.

Replacing Brake System Parts
The braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together if
the vehicle is to have really good braking. Your
vehicle was designed and tested with top-quality GM
brake parts. When you replace parts of your braking
system Ð for example, when your brake linings
wear down and you need new ones put in Ð be sure
you get new approved GM replacement parts. If you do
not, your brakes may no longer work properly. For
example, if someone puts in brake linings that are wrong
for your vehicle, the balance between your front and
rear brakes can change Ð for the worse. The braking
performance you have come to expect can change
in many other ways if someone puts in the wrong
replacement brake parts.
Battery
Your new vehicle comes with a maintenance free
battery. When it is time for a new battery, get one that
has the replacement number shown on the original
battery's label. We recommend an ACDelco
žbattery.
SeeEngine Compartment Overview on page 5-12for battery location.
Warning:Battery posts, terminals and related
accessories contain lead and lead compounds,
chemicals known to the State of California to cause
cancer and reproductive harm. Wash hands after
handling.
Vehicle Storage
If you are not going to drive your vehicle for 25 days
or more, remove the black, negative (-) cable from the
battery. This will help keep your battery from
running down.
{CAUTION:
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
are not careful. See
Jump Starting on
page 5-43
for tips on working around a battery
without getting hurt.
Contact your dealer to learn how to prepare your
vehicle for longer storage periods.
