1996 GMC SIERRA service interval

How to Check
Use a good quality pocket-type gage to check tire
pressure.
You can’t tell if your tires are properly inflated
simply by looking at them. Radial tires may
look
properly inflated even when they’re underinflated.
Be sure
to put the valve caps back on the valve
stems. They help prevent leaks
by keeping out dirt
.and moisture.
Tire Inspection and Rotation
Tires should be inspected every 6,000 to 8,000 miles
(10 000 to 13 000 km) for any signs of unusual wear. If
unusual wear
is present, rotate your tires as soon as
possible and check wheel alignment. Also check for
damaged tires or wheels. See “When It’s Time for New
Tires” and ‘‘Wheel Replacement” later
in this section for
more information.
If your vehicle has dual rear wheels,
also see “Dual ‘Tire Operation” later
in this section.

FRT FRT

The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation
is the most important. See “Scheduled
Maintenance Services”
in the Index for scheduled
rotation intervals.
If
your vehicle has single rear wheels, always use one of
the correct rotation patterns
shown here when rotating
your tires.
If your vehicle has front [Ires with different load ranges
or tread designs (such as all season vs. on/off road) than
the rear tires, don’t rotate your tires front to rear.

Part B: Owner Checks and Services
Listed below are owner checks and services which
should be performed at the intervals specified
to help
ensure the safety, dependability and emission control
performance
of your vehicle.
Be sure any necessary repairs are completed at once.
Whenever any fluids or lubricants are added to your
vehicle, make sure they are the proper
ones, as shown
in Part D.
At the First 100, 1,000 and 6,000 Miles
(160,1600 and 10 000 km)
For vehicles with dual wheels, check dual wheel nut
torque. For proper torque, see “Wheel Nut Torque” in
the Index.
At Each Fuel Fill
Engine Oil Level Check
Check the engine oil level and add the proper oil if necessary.
See “Engine Oil”
in the Index for further details.
Engine Coolant Level Check
Check the engine coolant level and add the proper
coolant mix
if necessary. See “Engine Coolant” in the
Index for further details.
Windshield Washer Fluid Level Check
Check the windshield washer fluid level in the
windshield washer tank and add the proper fluid
if
necessary. See “Windshield Washer Fluid” in the Index
for further details.
A Least Once a Month
Tire Inflation Check
Make sure tires are inflated to the correct pressures.
See “Tires”
in the Index for further details.
Cassette Deck Service
Clean cassette deck. Cleaning should be done every
50 hours of tape play. See “Audio Systems” in the
Index for further details.

Brake System Inspection
Inspect the complete system. Inspect brake lines and
hoses for proper hook-up, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads for wear and rotors
for surface condition. For vehicles with rear drum
brakes, also inspect drum brake linings for wear and
cracks. Inspect other brake parts, including drums,
wheel cylinders, calipers, parking brake, etc. Check
parking brake adjustment. You may need to have your
brakes inspected more often
if your driving habits or
conditions result
in frequent braking.
