2003 Oldsmobile Alero Engine

The windshield washer
fluid reservoir is located in
the engine compartment
towards the front of
the vehicle. Notice:
Open the cap with the washer symbol on it. Add washer
fluid until the tank is full. When
using concentrated washer fluid, follow
the manufacturer’s instructions for adding
water.
Don’t mix water with ready-to-use washer fluid.
Water can cause
the solution to freeze and
damage your washer fluid tank and other parts
of the washer system.
Also, water doesn’t
clean as well as washer fluid.
Fill your washer fluid tank only three-quarters
full when
it’s very cold. This allows for
expansion if freezing occurs, which could damage the tank if
it is completely full.
Don’t use engine coolant (antifreeze)
in your
windshield washer.
It can damage your
washer system and paint.

Brakes
Brake Fluid
Your brake master cylinder reservoir is on the driver’s
side
of the engine compartment. It is filled with
DOT-3 brake fluid. See
Engine Compartment Overview
on page 5- 72.
There are only two reasons why the brake fluid level in
the reservoir might go down. The first is that the
brake fluid goes down to an acceptable level during
normal brake lining wear. When new linings are put in,
the fluid level goes back up. The other reason is
that fluid
is leaking out of the brake system. If it is, you
should have your brake system fixed, since a leak
means that sooner or later your brakes won’t work well,
or won’t work at all.
So, it isn’t a good idea to “top off your brake fluid.
Adding brake fluid won’t correct a leak.
If you add fluid
when your linings are worn, then you’ll have too
much fluid when you get new brake linings. You should
add (or remove) brake fluid, as necessary, only when
work is done on the brake hydraulic system.
If you have too much brake fluid, it can spill on
the engine. The fluid will burn if the engine is
hot enough. You or others could be burned,
and your vehicle could be damaged. Add brake
fluid only when work
is done on the brake
hydraulic system.

When your brake fluid falls
to a low level, your brake
warning light will come on. See
Brake System Warning
Light on page
3-28.
What to Add
When you do need brake fluid, use only DOT-3 brake
fluid. Use new brake fluid from a sealed container
only. See
Part D: Recommended Fluids and Lubricants
on page
6- 15.
Always clean the brake fluid reservoir cap and the area
around the cap before removing it.
This will help
keep dirt from entering the reservoir.

system, your brakes may not work well, or
they may not even work at all.
This could
cause a crash. Always use the proper
brake fluid.
Notice:
Using the wrong fluid can badly damage brake
system parts. For example, just a few drops
of
mineral-based oil, such as engine oil, in your
brake system can damage brake system
parts
so badly that they’ll have to be replaced.
Don’t let someone put in the wrong kind of fluid.
If you spill brake fluid on your vehicle’s painted
surfaces, the paint finish can be damaged. Be careful not to spill brake fluid on your vehicle. If
you do, wash
it off immediately. See
“Appearance Care’’ in the Index.

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
- for example, when your brake linings
wear down and you need new ones put in
- be sure
you get new approved replacement parts. If you
don’t, 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
- for the worse. The braking
performance you’ve come
to expect can change in
replacement brake parts.
many other ways if someone puts in the wrong
Battery
Your new vehicle comes with a maintenance free
ACDelco@ battery. When it’s time for a new battery, get
one that has the replacement number shown on the
original battery’s label. We recommend an ACDelcoC”-‘
battery. See
Engine Compartment Overview on
page
5- 12 for 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’re 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.
Batteries have acic bat can burn you and gas
that can explode. You can be badly hurt
if you
aren’t careful. See “Jump Starting” in the Index

Jump Starting
If your battery has run down, you may want to use
another vehicle and some jumper cables to start your
vehicle. Be sure to follow the steps below to do it safely.

burn you.
If you don’t follow these steps exactly, some
or all of these things can hurt you.
Notice: Ignoring these steps could result in costly
damage to your vehicle that wouldn’t be covered
by your warranty.
Trying to start your vehicle by pushing or pulling
it
won’t work, and it could damage your vehicle.
1. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.
Notice: If the other system isn’t a 12-volt system
with a negative ground, both vehicles can be
damaged.
2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren’t touching
each other.
If they are, it could cause a ground
connection you don’t want.
You wouldn’t be able to
start your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved in
the jump start procedure. Put an automatic
transaxle in PARK (P) or a manual transaxle in
NEUTRAL before setting the parking brake.
Notice: If you leave your radio on, it could be badly
damaged. The repairs wouldn’t be covered by
your warranty.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter. Turn
off the radio and all lamps that aren’t
needed. This will avoid sparks and help save
both batteries. And it could save your radio!
4. Open the hoods and locate the batteries. Find the
positive
(+) and negative (-) terminal locations on
each vehicle. See
Engine Compartment Overview
on page
5-12 for more information on location.

hands, clothing and tools away from any

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 tsthe ACDelco@
battery installed
in your new 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.
CAUTION: (Continued) 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.

missing insulation.

Before you connect the cables, here are some
basic things you should know. Positive
(+) will go to
positive
(+) or to a remote positive (+) terminal if
the vehicle has one. Negative (-) will go to a heavy,
unpainted metal engine part or to a remote
negative
(-) terminal if the vehicle with the dead
battery has one.

8. Now connect the black
negative
(-) cable to the
negative
(-) terminal
of the good battery. Use
a remote negative
(-)
terminal
if the vehicle
has one.
Don’t let the other end touch anything until the next
step. The other end
of the negative (-) cable
doesn’t go to the dead battery. It goes to a heavy,
unpainted metal engine part or to a remote
negative
(-) terminal on the vehicle with the dead
battery.
9. Connect the other end of the negative (-) 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, and the chance
of sparks getting back to the battery is much less.
10. NnW nt8t-t the vehicle with the coed battery and run
the engine for a while.

11. Try to start the vehicle that has the dead battery. If
it won’t start after a few tries, it probably needs
service.
Notice: Damage to your vehicle may result from
electrical shorting
if jumper cables are removed
incorrectly. To prevent electrical shorting, take care
that the cables don’t touch each other or any
other metal. The repairs wouldn’t be covered by
your warranty.
