1994 CADILLAC FLEETWOOD engine oil

rags containing used engine oil. (See the manufacturer’s warnings about
the use and disposal of oil products.)
Used oil can be a real threat to the environment.
If you change your own
oil, be sure to drain all free-flowing oil from the filter before disposal.
Don’t ever dispose of oil by putting.it
in the trash, pouring it on the
ground, into sewers, or into streams or bodies
of water. Instead, recycle it
by taking it to a place that collects used oil. If you have a problem
properly disposing of your used oil, ask your dealer, a service station or a
local recycling center for help.
AIR CLEANER
c- c
See “Scheduled Maintenance Services” in the Index. Refer
to the
Maintenance Schedule
to determine when to
replace the air filter.

-NOTICE:
If the air cleaner is off, a backfire can cause a damaging engine
fire:And, dirt can easily get into your engine, which will damage
it. Always have the air cleaner in place when you’re driving. I
I AUTOAUTIC .TRANsIMISSION FLUID
‘When to Check and Change
A good time to check your automatic transmission fluid level is when the
engine oil is changed. Refer to the Maintenance Schedule to determine
when to change your fluid. See “Scheduled Maintenance Services” in
the Index.
How to Check
Because this operation can be a little difficult, you may choose to have
this done at .a Cadillac dealership Service Department.
If you do it yourself, be sure to follow all the instructions here, or you
cou.ld get a false reading on the dipstick.
I I Too NOTICE: much or too little fluidcan damage your. transmission. Too
much can mean that some of the fluid could come out and fall
on hot engine parts or exhaust system, starting
a fire. Be sure to
get an accurate reading
if you check your transmission fluid. i
I
Wait at least 30 minutes before checking the transmission fluid level if
you
have been driving:
When outside temperatures are above 90°F (32OC).
At high speed for. quite a while.

What to Use
Standard Differential
Use Axle Lubricant (GM Part No. 1052271) or SAE 8OW-90 GL-5 gear
lubricant.
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 Cadillac
will:
Give freezing protection down to -34 F (-37 C).
Give boiling protection up to 262 F (128 C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
I Let the warning lights work as they should.
1 What to Use
Use a mixture of one-half clean water (preferably distilled) and one-half
antifreeze that meets “GM Specification 1825-M,” which won’t damage
aluminum parts.
You can also use a recycled coolant conforming to GM
Specification 1825-M with a complete coolant flush and refill. Use GM
Engine Coolant Supplement (sealer) with any complete coolant change.
If you use this mixture, you don’t need to add anything else.

I
You can check the brake fluid without taking off the cap. Just look at the
windows on the brake fluid reservoir. The fluid levels should be above
“MIN.”
If they aren’t, have your brake system checked to see if there is a
leak.
After work is done
on the brake hydraulic system, make sure the levels
are above “MIN” and below the top
of each window.
What to Add
When you do need brake fluid, use only DOT-3 brake fluid -- such as
Delco Supreme
ll@ (GM Part No.1052535). Use new brake fluid from a
sealed container only, and always clean the brake fluid reservoir cap
.before removing it.
NOTICE:
DOT-5 silicone brake fluid can damage your vehicle. Don’t
use it.
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 Cadillac has front-wheel disc brakes and rear drum 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).
