Oil Pressure Gage
Standard Cluster Digital Cluster
The oil pressure gage shows the engine oil pressure in psi (\
pounds per square inch) when the engine is running. Canadian vehicles ind\
icate pressure
in kPa (kilopascals). Oil pressure may vary with engine speed\
, outside
temperature and oil viscosity, but readings above the low press\
ure zone indicate the normal operating range.
A reading in the low pressure zone may be caused by a dangerous\
ly low oil
level or other problem causing oil pressure.
On the digital cluster, a box around the oil pressure symbol \
will begin to flash
when the
oil pressure is low.
CAUTION
Don't keep driving if the oil pressure is low. If you do, your engine
can become
so hot that it catches fire. You or others could be
burned. Check your oil as soon as possible and have your vehi\
cle
serviced.

Operating the engine with the air cleaner off can cause you or other!
to be burned. The air cleaner not only cleans the air, it stops flame
if the engine backfires. If it isn’t there, and the engine backfires, you
could be burned. Don’t drive with it off, and be careful working on
the engine with the air cleaner off.

Automatic Transmission Nuid
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 choo\
se to have this
done at a
GM dealership 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.
Too much or too little fluid can damage your transmission. Too much can
mean that some of the fluid could come out and fall on hot engine part-
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 (32°C).
At high speed for quite a while.
In heavy traffic-especially in hot weather.
While pulling a trailer.

PO453
The following explains your cooling system and how to add cool\
ant when it is low.
If you have a problem with engine overheating, see "Engine
Overheating" in the Index.
The proper coolant for your vehicle will:
Give freezing protection down to -20°F (-29°C) or -40°F (-40°C) for
Canadian vehicles and vehicles with the cold climate option.
Give boiling protection up to 258°F (125°C).
Protect' against rust and corrosion.
Help keep the proper engine temperature.
Let the warning gages work as they should,
What to Use:
Use a mixture of clean water (preferably distilled) and antifreeze that meets
"GM Specification 6038-M," which won't damage aluminum parts.
Also use
GM Engine Coolant Supplement (sealer) with a complete coolant \
change.
If
you use these, you don't need to add anything else.

Explanation Of Scheduled Maintenance Services
Below are explanations of the services listed in the maintenance charts.
The proper fluids and lubricants to use are listed in this section. Make sure
whoever services your vehicle uses these. All parts should be \
replaced and
all necessary repairs done before you or anyone else drives th\
e vehicle.
1. ENGINE OIL AND OIL FILTER CHANGE* -ALWAYS USE SG OR
SG/CE QUALITY, ENERGY CONSERVING II OILS OF THE PROPER
VISCOSITY.
To determine the preferred viscosity oil for your vehicle’s
engine (e.g. SAE 5W-30). See “Engine Oil” in the Index.
bushings, steering linkage, transfer case shift linkage, parking \
brake cable
guides, propshaft splines, universal joints and brake pedal spri\
ngs at the
intervals specified on the proper maintenance schedule or at ev\
ery
engine oil change, whichever comes first.
2.
CHASSIS LUBRICATION -Lubricate the front suspension, king pin
Ball joints and king pin bushings should not be lubricated unl\
ess their
temperature is
10°F (-12”C), or higher. When the weather is cold, let
them warm up before lubrication or they could be damaged.
Also, be sure to check all the vehicle fluid levels at this time.
3.
COOLING SYSTEM SERVICE* -Drain, flush and refill system with new
coolant. See the Index under “Engine Coolant” for the pro\
per coolant and mixture to use in your vehicle.
Also inspect the hoses and replace them
if they are cracked, swollen, or
deteriorated. Tighten all hose clamps. Clean the outside of the radiator
and air conditioning condenser. Wash the radiator neck.
To ensure proper
operation, pressure test the radiator and cap.
4. AIR CLEANER FILTER REPLACEMENT* -Replace at specified
intervals. Replace more often under dusty conditions. Ask your \
dealer for
the proper replacement intervals for your driving conditions.
5. FRONT WHEEL BEARING REPACK (2-WHEEL DRIVE ONLY) -Clean
and repack the front wheel bearings at each brake relining, or at the
specified interval, whichever comes first.
* An Emission Control Service
