The 4.0L Aurora engine uses an engine accessory belt.
This diagram shows the features connected by the belt
routing. See”Maintenance Schedu1e”in the Index for
when to check the belt.

Engine Oil
If the CHECK 01L LEVEL message or the oil warning
light on the instrument panel comes
on, it means you
need to check your engine oil level right away.
For more
information, see “Check Oil Level Message” or
“Oil
Warning Light” in the Index. You should check your
engine
oil level regularly; this is an added reminder.
It’s a
good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
Turn off the engine and give the
oil a few minutes to
drain back into the oil pan.
If you don’t, the oil dipstick
might not show the actual level.

Engine Coolant
The following explains your cooling system and how to
add coolant when
it is low. If you have a problem with
engine overheating, see “Engine Overheating” in the
Index.
The proper coolant for your Aurora will:
0 Give freezing protection down to -34°F (-37°C)
0 Give boiling protection up to 262°F (128°C).
0 Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights work as they should.
What to Use
Use a mixture of one-half c.lt.crr~ wwtor (preferably
distilled) and one-half antifreeze that meets “GM
Specification 182S-M,” which won‘t damage aluminum
parts.
You call also use a recycled coolant conforming to
GM Specification 1825-M
with a complete coolant tlush
and refill. Use GM Engine Coolant Supplement (sealer)
with any cotnplete coolant flush and refill. If you use
this mixture, you don‘t need to add anything else.
A
special procedure is required for adding sealer; see the
ALI~o~~ Service Manual. (To order a service 1nanual. see
”Service Publications“
in the Index.)

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.
When your brake fluid falls
to a low level, your brake
warning light
will come on. A chime will sound if you
try to drive
with this warning light 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. 1052535). Use new brake fluid from a sealed
container only, and always clean the brake fluid
reservoir cap before removing it.
I NOTICE:
Don’t let someone put in the wrong kind of
fluid. 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.
Brake fluid can damage paint, so be careful
not
to spill brake fluid on your vehicle. If
you do, wash it off immediately. See
“Appearance Care” in the Index.

Brake Wear
Your Aurora has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that make
a high-pitched warning sound when the brake pads are
worn and new pads are needed. The sound may come
and
go or be heard all the time your vehicle is moving
(except when
you are pushing on the brake pedal
firmly).
I NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
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.
Brake linings should always
be replaced as complete
axle sets.
Brake Pedal Travel
See your retailer 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 YOLI apply the brakes, with or without the
vehicle moving, your brakes adjust for wear.
