1994 GMC SIERRA recommended oil

Never use too much of any lubricant and be sure to wipe up any extra
lubricant when
you are finished.
Your maintenance schedule
will tell you how often to lubricant these items.
See “Recommended Fluids and Lubricants”
in the Index for the proper
lubricant
to use.
Lock Cylinders
To be sure your locks operate properly, they must be lubricated. Your
vehicle’s maintenance schedule will
tell you how often to lubricate them.
See “Recommended Fluids and Lubricants”
in the Index for the proper
lubricant
to use.
You should not use penetrating oils because they could wash
out the factory
installed lubricant and cause the lock
to bind. De-icers which contain
alcohol could
also wash away the lubricant, so be sure to lubricate the lock
after using
a de-icer of this type.
Tailgate Handle
The tailgate handle pivot points on your vehicle should be lubricated to keep
the handle working smoothly.
Your maintenance schedule
will tell you how often to lubricant the handle.
See “Recommended Fluids and Lubricants” in the Index for the proper
lubricant to use.
Battery
Every new GM vehicle has a Delco Freedom@ battery. You never have to
add water to
one of these. When it’s time for a new battery, we recommend
a Delco Freedom@ battery. Get one that has the catalog number shown on
the original battery’s label.
Vehicle Storage
If you’re not going to drive your vehicle for 25 days or more, take off the
black, negative (-) cable from the battery. This will help keep your battery
from running down.

Aluminum Wheels (If So Equipped)
Your aluminum wheels have a protective coating similar to the painted
surface
of your vehicle. Don’t use strong soaps, chemicals, chrome polish,
abrasive cleaners or abrasive cleaning brushes on them because you could
damage this coating. After rinsing thoroughly, a wax may be applied.
NOTICE:
If you have aluminum wheels, don’t use an automatic vehicle
wash that has hard silicon carbide cleaning brushes. These
brushes can take
off the protective coating.
White Side wall Tires
Your GM dealer has a GM White Sidewall Tire Cleaner. You can use a stiff
brush with the cleaner.
Weatherstrips
Silicone grease on weatherstrips will make them last longer, seal better, and
not stick or squeak. Apply silicone grease with
a clean cloth at least every
six months. During very cold, damp weather more frequent application may
be required. (See “Recommended Fluids
& Lubricants” in the Index.)
Sheet Metal Damage
If your vehicle is damaged and requires sheet metal repair or replacement,
make sure
the body repair shop applies anti-corrosion material to the parts
repaired or replaced
to restore corrosion protection.
Foreign Material
Calcium chloride and other salts, ice melting agents, road oil and tar, tree sap,
bird droppings, chemicals from industrial chimneys, and other foreign matter
can damage your vehicle’s finish
if they remain on painted surfaces. Use
cleaners that are marked safe for painted surfaces to remove foreign matter.
Finish Damage
Any stone chips, fractures or deep scratches in the finish should be repaired
right away. Bare metal will corrode quickly and may develop into a major
repair expense.
Minor chips and scratches can be repaired with touch-up materials available
from your dealer or other service outlets. Larger areas of finish damage can
be corrected
in your dealer’s body and paint shop.

Locking differential - Drain fluid at first oil change and refill.
Check fluid level and add
as needed at subsequent oil changes. In
dusty areas, or trailer towing applications drain fluid at every
15,000 miles (24 135 kilometers) and refill.
Standard differential - Check fluid level and add as needed at
every
oil change. In dusty areas, or trailer towing applications,
drain fluid every
15,000 miles (24 I35 kilometers) and refill.
More frequent lubrication may be required on heavy-duty or
off-road use.
3500 HD Models - 3500 HD Models with applications requiring
extreme overload/trdiler tow conditions
and high speed conditions
(above 45 mph (72
kdh)) for extended periods of time must
change drive axle fluid every
3,000 miles (4828 kilometers) or 3
months, whichever comes first, OR must use 75W-140 synthetic
fluid meeting
GM specifications. See “Recommended Fluids and
Lubricants” at the end of this section for the proper fluid to use.
25.
BRAKE SYSTEM INSPECTION-f - When the engine oil is
changed, inspect the lines and hoses for proper hookup, binding, leaks,
cracks, chafing, etc. Check the parking brake adjust, and the fluid level
in the master cylinder. A low fluid level can indicate worn disc brake
pads which may need
to be serviced.
When the wheels are removed for rotation, inspect disc brake pads for
wear and rotors for surfxe condition. Also inspect drum brake linings
for wear and cracks. Inspect other brake parts, including drums, wheel
cylinders, parking brake, etc., at the same time. Remove any
rust or dirt
from the wheel and mounting surfaces before mounting the wheel.
Inspect brakes more often if driving habits or conditions result in
frequent braking.
?A fluid loss in these systems may indicate a problem. Have them
inspected and repaired at once.

Owner Checks and Services
Listed below are owner checks and services which should be made at the
time period specified to help ensure proper safety, emission performance,
and dependability
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 this Section.
At Least Once a Month
Tire inflation pressure check - Check the tires for proper inflation. If
they are low, inflate them to the level specified on the Certification/Tire
label. See “Loading Your Vehicle” or “Inflation-Tire Pressure”
in the Index.
At Least Once a Year
Key lock cylinder lubrication - Lubricate key lock cylinders with engine
oil. See
the “Recommended Fluid and Lubricants” chart in this section.
Transmission neutral or clutch start switch operation -
1. Before you start, be sure you have enough room around the vehicle.
2. Firmly apply both the manual parking brake and the regular brake. See
“Brakes” and “Parking Brake”

pedal.
3. Be ready to turn off the engine immediately if it starts.
4. On automatic transmission vehicles, try to start the engine in each gear.
The starter should work only
