1995 PONTIAC BONNEVILLE engine oil

As shown in the chart, SAE 1OW-30 is best for your
vehicle. However, you can use
SAE 5W-30 if it’s
going to be colder than
60” F ( 16” C) before your
next oil change. When it’s very cold,
you should use
SAE 5W-30. These numbers on an oil container show
its viscosity, or thickness. Do not use other viscosity
oils, such as
SAE 20W-50.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
“Starburst” symbol. Failure to use the proper
oil
can result in engine damage not covered by your
warranty.

What to Do with Used Oil
Did you how that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don’t let used oil stay on your
skin
for very long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly throw
away clothing or 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 co’llects lased 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
Refer to the Maintenance Schedule to determine when to
replace the air filter.
See “Scheduled Maintenance Services”
in the Index.
NOTICE:
If the air cleaner is off, a backfire can cause a
damaging engine &e. And, dirt can eady get
into your engine,
which will damage it. Always
have the air cleaner in place when you’re driving.

Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle fluid level
is when the engine oil is changed. Refer to the
Maintenance Schedule to detemrrine 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 your Pontiac dealer Service
Department.
If you do it yourself, be sure to follow all the
instructions here, or you could get a false reading on the
dipstick.
NOTICE:
Too much or too little fluid can damage your
transaxle.
Too much can mean that some of the
fluid could come out and fall
on hot engine parts
or exhaust system parts, starting a fire. Be sure to
get an accurate reading if you check your
transaxle fluid.
~~~
Wait at least 30 minutes before checking the transaxle
fluid level
if you have been driving:
0 When outside temperatures are above 90" F (32°C).
At high speed for quite a while.
In heavy traffic - especially in hot weather.
0 While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which is
180 "F to 200°F (82" C
to 93 "C).
Get the vehicle warmed up by driving about €5 des (24 km)
when outside temperatures are above 50°F (10°C). If it's
colder
than 50°F (lO"C), you may have to drive longer.
To check the fluid level
1. Park your vehicle on a level place. Keep the engine
running.
2. With the parking brake applied, place the shift lever
in PARK (P).
3. With your foot on the brake pedal, move the shift
lever through each gear range, pausing for about
three seconds
in each range. Then, position the shift
lever in PARK (P).
4. Let the engine run at idle for three to five minutes.

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 co’olant for your Pontiac 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.
Help keep the proper engine temperature.
Let the warning Sights work as they should.
What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half antifreeze that meets
“GM
Specification 1825M,?’ which won’t damage aluminum
parts. You can also use a recycled coolant conforming to
GM specification 1825M with a complete coolant flush
and refill. Use GM Engine Coolant Supplement (sealer)
with
any complete coolant flush and refill. If you use
this mixture,
you don’t need to add anything else.
NOTICE:
If you use an improper coolant nrsix, yuur engine
could overheat and be badly damaged. The
repair cast wouldn’t be mvmd by your

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:
~ 0 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 Pontiac has front 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).
