Downloaded from www.Manualslib.com manuals search engine Oil Pressure Gage
I
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 Pa (kilopascals). Oil pressure may vary with engine speed,
outside temperature and oil viscosity, but readings above the l\
ow 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.
NOTICE:
Damage to your engine from neglected oil problems can be
costly and
is not covered by your warranty.
Indicator Lights
Indicator lights go on when you use your turn signals, change from low
beam headlights to high beams, or when you use your hazard fl\
ashers. The
next few pages will also tell you about the indicator lights \
on your vehicle
and help you locate them.

DO
NOT USE SAE 1OW-40, SAE

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
oil container show its viscosity, or thickness. Do not use
other viscosity oils, such as
SAE 1OW-40 or SAE 20W-50.

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.
1. 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 “SWCD”, or
“SH, SG,
CD,” or “SGKD”, etc. To determine the preferred viscosity oil for your
vehicle’s engine (e.g. SAE 5W-30), see “Engine
Oil” in the Index.
2. 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.
3.
COOLING SYSTEM SERVICE* - Drain, flush and refill the
system with new or approved recycled coolant conforming to “\
GM
Specification 6038-M” (4.3L engine) or “GM Specification 6043-M”
(2.2L engine). 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.
4. AIR CLEANER FILTER REPLACEMENT* - Replace at
specified intervals. Ask your dealer for the proper replacement
intervals for your driving conditions.
5. FRONT WHEEL BEARING REPACK (%WHEEL DRIVE
ONLY) - Clean and repack the front wheel bearings at each brake
relining, or at the specified interval, whichever comes first.
