Standard Cluster Digital Cluster
f
The oil pressure gage shows the engine oil pressure in psi (pounds per
square inch) when the engine is running. Canadian vehicles indicate
pressure in kPa (kilopascals). Oil pressure may vary with engine speed,
outside temperature and
oil viscosity, but readings above the low pressure
zone indicate the normal operating range.
A reading in the low pressure zone may be caused by a dangerously low oil
level or other problems causing low
oil pressure.
On the digital cluster, a box around the oil pressure symbol
will begin to
flash when the oil pressure is low.
Don't keep driving if the oil pressure is low. If you do, your

can use
SAE low-30 if it’s going to be 0°F (-1 8°C) or above. These

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

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 the vehicle.

ENGINE OIL AND OIL FILTER CHANGE* - ALWAYS USE
API SERVICE SH OR SG ENERGY CONSERVING I1 OILS OF THE
PROPER VISCOSITY. The “SH” or “SG” designation may be shown
alone or in combination with others, such as “SHKD”, or
“SH, SG,
CD,” or “SG/CD”, etc.
To determine the preferred viscosity oil for your
vehicle’s engine (e.g. SAE
5W-30), see “Engine Oil” in the Index.
CHASSIS LUBRICATION - Lubricate the front suspension, ball
joint, steering linkage, and transfer case shift linkage, parking brake
cable guides, propshaft splines, universal joints, brake pedal springs,
and clutch pedal springs at the intervals specified on the proper
maintenance schedule, or at every engine oil change, whichever comes
first.
Ball joints should
not be lubricated unless their temperature is 10°F
(-12°C) or higher. When the weather is cold, let them warm up before
lubricating them
or they could be damaged.
Also, be sure to check all the vehicle fluid levels at this time.
COOLING SYSTEM SERVICE* - Drain, flush and refill the
system with new or approved recycled coolant conforming to “GM
Specification
603%”’. See “Engine Coolant” in the Index for the
proper coolant and mixture to use in your vehicle.
Also inspect
the hoses and replace them if they are cracked, swollen, or
deteriorated. Clean the outside of the radiator and air conditioning
condenser. Wash the radiator neck. To ensure proper operation,
pressure test the radiator and cap.
AIR CLEANER FILTER REPLACEMENT” - Replace at
specified intervals. Ask your dealer for the proper replacement
intervals for your driving conditions.
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.
