NOTICE:
If you keep driving your vehicle with
this light on, after a while the emis-
sion controls won’t work as well,
your fuel economy won’t be as good
and your engine may not run as
smoothly. This could lead to costly
repairs not covered by your warranty.

hgine Oil Pressure Gage
‘his gage tells you if there could be a
roblem with your engine oil pressure.
’he engine oil pressure gage shows the
ngine oil pressure in psi (pounds per
quare inch)
in the U.S., or kPa
cilopascals) in Canada, when the engine
; running. Oil pressure should be 20 to
0 psi (140 to 550 kPa). It may vary with
ngine speed, outside temperature and
il viscosity, but readings above the red
rea show the normal operating range.
leadings in the red area tell you that the
ngine is low on oil, or that you might
ave some other oil problem. See “Engint
Iil” in the Index.
NOTICE:
Damage to your engine from
neglected oil problems can be costly
and is not covered by your warqanty.

NOTICE:
Don’t add too much oil. If your
engine has
so much oil that the oil
level gets above the cross-hatched
area that shows the proper operating
range, your engine could be dam-
aged.

somewhere
in the proper operating range.
Push the dipstick all the way back

What Kind of Oil to Use:
3eginning midyear 1993, oils of the
roper quality for your vehicle will be
dentified with this new “starburst”
‘ymbol. The “starburst” symbol indicates
hat the oil has been certified by the
imerican Petroleum Institute (API), and
s preferred for use in your gasoline
mgine.
r‘ou should
look for this on the front of
he oil container, and use only oils that
lisplay this new symbol.
You should also use
the proper viscosity
il for your vehicle, as shown in the
following chart.

IF NllTHER SAE SW-30 NOR SAE 1OW-30 GRADE OILS ARE AVAILABLE, SAE 30 GRADE

ANY OTHER GRADE OIL NOT RECOMMENDED. Dd NO? USE SAE 1OW-40, SAE 2OW-50 OR
As shown in the chart, SAE 5W-30
is best for your vehicle. However,
you can use
SAE 1OW-30 if it’s
going to be
0°F (-18°C) or above.
These numbers on an oii container
show its viscosity,
or thickness. Do
not use other viscosity oils such as
SAE 1OW-40 or SAE 20W-50.
If you cannot find oils with
the new
“starburst” symbol on the front of the
container, you should look for and use
oils containing the following three
things:

SH or SG
“SH” or “SG” must be on the oil
container, eithet by itself or
combined
with other quality
designations, such as “SWCD,”
“SH, SG, CD,” “SGKD,” etc.
These letters show American
Petroleum Institute
(API) levels of
quality.

Oils with these words on the
container will help you save fuel. These three things are usually
included in a doughnut shaped logo
(symbol) on most containers. If you
cannot find oils with the “starburst”
symbol, you should look for oils
with the doughnut shaped symbol,
containing the three things noted
above.
NOTICE:
If you use oils that do not have
either the “starburst” symbol or an
API SH or SG designation, you can
cause engine damage not covered
by your warranty.
GM Goodwrench@ oil
(in Canada,
GM Engine Oil) meets all the
requirements for your vehicle.
Engine Oil Additives:
Don’t add anything to your oil. Your
Pontiac dealer is ready to advise
if you
think something should be added.

Explanation of Scheduled
Maintenance Services
Following are explanations of the services
listed in Schedule I and Schedule
II.
The proper fluids and lubricants to use are
listed in Section
D. Make sure whoever
services your vehicle uses these. All parts
should be replaced and all necessary
repairs done before you or anyone else
drives the vehicle.
NOTE: To determine your engine’s
displacement and code, see
“Engine Identification” in the
Index.

Chassis Lubrication
- Lubricate
the suspension and steering
linkage. Lubricate the
transmission
shift linkage.
Tire and Wheel Rotation and
InsDection
- For proper wear
and maximum tire life, rotate
your tires following the
instructions in this manual. See
“Tires, Inspection and Rotation”
in the Index. Check the tires for
uneven wear or damage. If you
see irregular or premature wear,
check the wheel alignment.
Check for damaged wheels also.

InsDection
- Inspect the belt(s)
for cracks, fraying, wear and
proper tension. Replace as
needed. (Belts can have many small cracks in individual ribs
without affecting performance.)
ITEM
NO. SERVICE
5 Cooling: System Service* -
Drain, flush and refill the system
with new or approved recycled
coolant conforming to GM
Specification 1825M. Keep
coolant at the proper mixture as specified. See “Coolant”
in the
Index. This provides proper
freeze and boil protection, corrosion inhibitor level and
maintains proper engine operating temperature.
Inspect hoses and replace if they
are cracked, swollen or deterior-
ated. Tighten screw-type hose
clamps. Clean the outside of the
radiator and air conditioning
condenser. Wash the pressure cap and neck.
To help ensure proper operation,
we recommend a pressure test of
both the cooling system and the
pressure cap.
