-
Turning the surge tank pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn you badly.
Never turn the surge tank pressure cap
-- even a
little
-- when the engine and radiator are hot.
When your engine is cold, the coolant level should be at
the
KALT/COLD line (seam).
If this light comes on, it
means you’re low
on
engine coolant.
Adding Coolant
If you need more coolant, add the proper DEX-COOL@
coolant mixture at the surge tank, but only when the
engine is
cool.
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 replacing the surge tank pressure cap, make sure
it
is tight.
For more information, see “Low Coolant Light” in
the Index.

NOTICE:
The surge tank cap is a 15 psi (105 kPa)
pressure-type cap and must be tightly installed to prevent coolant loss and possible engine
damage from overheating.
If the surge tank pressure cap needs to be replaced, a
GM cap is recommended.
Thermostat
Engine coolant temperature is controlled by a thermostat
in the engine coolant system. The thermostat stops the
flow
of coolant through the radiator until the coolant
reaches a preset temperature.
If the thermostat needs to be replaced, a GM thermostat
is recommended. The
power steering fluid reservoir
is located between
the battery and the brake master cylinder on the driver’
side
of the engine.
When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system or
you hear an unusual noise. A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.

When the engine compartment is cool, wipe the cap and
the top of the reservoir clean, then unscrew the cap and
wipe the dipstick with a clean rag. Replace the cap and
completely tighten it. Then remove the cap again and
look at the fluid level on the dipstick.
The level should be at the full mark. There are two lines
on the dipstick. The top line is the “full” mark and the
bottom
line is the “add” line (which means that fluid
should be added). If necessary, add only enough fluid
to bring the level up to the
full mark.
What to Use
To determine what kind of fluid to use, see
“Recommended Fluids and Lubricants” in the
Maintenance Schedule booklet. Always use the
proper fluid. Failure to use the proper fluid can
cause leaks and damage hoses and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer’s instructions before use. If you will be
operating your vehicle
in an area where the temperature
may fall below freezing, use a fluid that has sufficient
protection against freezing.
Adding Washer Fluid
The windshield washer
fluid reservoir is located
behind the front grille
on the driver’s side
of
the engine.
Open the cap with the washer symbol on it. Add washer
fluid until
the tank is full.

Downloaded from www.Manualslib.com manuals search engine 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 radiator antifreeze in your
windshield washer. It can damage your
washer system and paint.
Brakes
Brake Fluid
Your brake master cylinder reservoir is here. It is filled
with DOT-3 brake fluid.
6-25
Page 269 of 338

Downloaded from www.Manualslib.com manuals search engine 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.
r
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” in the Index.
What to Add
When you do need brake fluid, use only DOT-3
brake fluid -- such as Delco Supreme 11 @ (GM
Part No. 12377967). Use new brake fluid from a
sealed container only.
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.

With the wrong kind of fluid in your brake
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:
0
0 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.
Your Catera has four-wheel disc brakes.
Your Catera has electronic wear sensors that let you
know when the front brake pads are significantly worn
and new pads are needed. The brake pad wear indicator
light will come
on and stay on when the brake pads are
worn and need
to be replaced. (See “Brake Pad Wear
Indicator Light”
in the Index.)
The brake pad wear indicator light means that
soon your brakes won’t work
well. That could
lead to
an accident. When the brake pad wear
indicator light comes on and stays on, have your
vehicle serviced.
I NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.

Downloaded from www.Manualslib.com manuals search engine Some driving conditions or climates may cause a
brake squeal when the brakes are first applied or
lightly applied. This does not mean something is
wrong with your brakes.
Properly torqued wheel bolts are necessary to help
prevent brake pulsation. When tires are rotated,
inspect brake pads for wear and evenly torque wheel
bolts in the proper sequence
to GM specifications.
Brake linings should always be replaced as complete
axle sets.
See “Brake System Inspection’’ in Section
7 of the
Maintenance Schedule booklet under Part
C “Periodic
Maintenance Inspections.”
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in pedal
travel. This could be a sign
of brake trouble.
Brake Adjustment
Every time you apply the brakes, with or without the
vehicle moving, your brakes adjust for wear.
Replacing Brake System Parts
The braking system on a modem 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 have to have new ones put in
-- be sure
you get new approved GM 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 many
other ways
if someone puts in the wrong replacement
brake parts.
