Filling the Tank
{CAUTION:
Fuel vapor is highly ammable. It burns
violently, and that can cause very bad injuries.
Do not smoke if you are near fuel or refueling
your vehicle. Keep sparks, ames and smoking
materials away from fuel.The fuel cap can be on either or both sides of your
vehicle depending on option content.
To take off the cap, turn it slowly counterclockwise.
{CAUTION:
If you get fuel on yourself and then something
ignites it, you could be badly burned. Fuel can
spray out on you if you open the fuel cap too
quickly. This spray can happen if your tank is
nearly full, and is more likely in hot weather.
Open the fuel cap slowly and wait for any
“hiss” noise to stop. Then unscrew the cap all
the way.
When you put the cap back on, turn it clockwise until it
is tight.
Notice:If you need a new fuel cap, be sure to get
the right type. Your dealer/retailer can get one for
you. If you get the wrong type, it may not t properly.
This may cause your malfunction indicator lamp to
light and may damage your fuel tank and emissions
system. SeeMalfunction Indicator Lamp on
page 3-36. Fuel caps for all
gasoline applications,
and all diesel between
frame rail fuel tank
applications

How to Inspect the Engine Air
Cleaner/Filters (DURAMAX®7.8L and
Isuzu 6H Diesel Engine)
{CAUTION:
Operating the engine with the air cleaner/lter
off can cause you or others to be burned. The
air cleaner not only cleans the air; it helps to
stop ames if the engine backres. If it is not
there and the engine backres, you could be
burned. Do not drive with it off, and be careful
working on the engine with the air cleaner/
lter off.
Notice:If the air cleaner/lter is off, a backre can
cause a damaging engine re. And, dirt can
easily get into your engine, which will damage it.
Always have the air cleaner/lter in place when you
are driving.The engine air cleaner/filter is located in the center of
the engine compartment.
To inspect the engine air cleaner/filter, perform the
following:
1. Disconnect the air
compressor hose by
pinching the connector
ring to release the
connector lock.
2. Unclip the four clips that hold the upper housing to
the lower housing and remove the upper housing.
3. Remove the filter from the vehicle and lightly shake
the filter to release loose dust and dirt. If the filter
remains caked with dirt, a new filter is required.
4. Reinstall the upper housing and make sure that the
air compressor hose is reconnected by pushing the
connector back onto the port. Listen for the
connector to click to be sure that the air compressor
hose is securely locked and connected.

Hood Inlet Seal
If your vehicle is being used in heavy snow conditions
or for snow plowing, there is a possibility of snow and
ice build up in the inlet to the air cleaner, blocking airflow
to the engine and negatively impacting engine
performance.
To prevent the blocking of air, remove the hood inlet
seal, by doing the following:
1. Loosen the clamp that holds the seal to the air
cleaner.
2. Slide the seal off.3. Store the seal in the inlet, located on the underside
of the hood.
4. Store the clamp on the coolant surge tank. Pull the
overflow tube out of the white plastic retainer, slip
the clamp over and reinstall the hose.
The seal will need to be replaced on to the air cleaner
for normal driving, especially in the warmer months.

Notice:In cold weather, water can freeze and crack
the engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mixture.
{CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it will burn if the engine parts are hot
enough. Do not spill coolant on a hot engine.
1. You can remove the
coolant surge tank
pressure cap when the
cooling system,
including the coolant
surge tank pressure
cap and upper radiator
hose, is no longer hot.
Turn the pressure cap slowly counterclockwise
about one full turn. If you hear a hiss, wait for that to
stop. A hiss means there is still some pressure left.2. Then keep turning the pressure cap slowly, and
remove it.
3. Fill the coolant surge tank with the proper mixture,
to the FULL COLD mark.

Rear Axle Shift Motor
When to Check and Change Fluid
If you have an optional air-shift two-speed, controlled
traction, or locking differential type rear axle, a good time
to check the fluid level in the axle shift motor is when
the rear axle lubricant is checked.
How to Check Fluid
Remove the plug on the front plate of the axle shift
motor, add enough fluid to raise the level to the bottom
of the filler plug hole, then replace the plug.
What to Use
Refer to your Maintenance Schedule to determine what
kind of lubricant to use. SeePart C: Recommended
Fluids and Lubricants on page 6-31.
Four-Wheel Drive
Transfer Case
When to Check Lubricant
It is not necessary to regularly check transfer case fluid
unless you suspect there is a leak or you hear an
unusual noise. A fluid loss could indicate a problem.
Have it inspected and repaired.
How to Check Lubricant
A. Fill Plug
B. Drain Plug
To get an accurate reading, the vehicle should be on a
level surface.
If the level is below the bottom of the fill plug hole,
located on the transfer case, you’ll need to add some
lubricant. Add enough lubricant to raise the level to
the bottom of the fill plug hole. Use care not to
overtighten the plug.

Hub-Piloted Wheels, 8-Hole or 10-Hole
The studs and nuts used with these wheels have
right-hand threads.
1. With intermittent pilot pads, position a pad at
12 o’clock to center the wheel and reduce run-out.
2. Put the tire and rim assembly on the axle hub.
Install the outer rear tire and rim assembly so
that its valve stem is exactly opposite the valve stem
on the inner tire and rim assembly.
3. Put on the wheel nuts.4. Finger-tighten the nuts.
5. Oil the surfaces (B)
between the nuts (C)
and washers (A).
Do not oil the studs or
the threads of the nut.

Service Parts Identication Label
This label is in a location determined by the body
manufacturer. It is very helpful if you ever need to order
parts. The label has the following information:
•Vehicle Identification Number (VIN)
•Model designation
•Paint information
•Production options and special equipment
Do not remove this label from the vehicle.
Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to your
vehicle unless you check with your dealer/retailer
rst. Some electrical equipment can damage your
vehicle and the damage would not be covered by
your warranty. Some add-on electrical equipment can
keep other components from working as they should.
Add-on equipment can drain your vehicle’s battery, even
if your vehicle is not operating.Your vehicle has an airbag system. Before attempting to
add anything electrical to your vehicle, seeServicing
Your Airbag-Equipped Vehicle on page 1-59.
Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the light switch. An electrical overload will cause the
lights to go on and off, or in some cases to remain off.
If this happens, have your headlamp wiring checked
right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by a circuit
breaker inside the motor and a circuit breaker or fuse in
the fuse block. If the motor overheats, the wipers will
stop until the motor cools. If the overload is caused by
an electrical problem, be sure to get it fixed.
5-102

Fusible Links
A fusible link is a short piece of wire several gauge
sizes smaller than the circuit it protects. It will melt in an
overload situation, opening the circuit.
Your starter and other circuits have these fusible links.
The size is printed on the insulation. If the insulation
is burned beyond recognition, consult your dealer for the
proper size. Replace a fusible link with one of the same
size and insulation type. Fusible link insulation is a
special purpose high-temperature material.
Some examples of circuits with fusible links are the
hydraulic brake booster motor feed circuit, the generator
output circuit, and the intake heater feed circuit in
vehicles with a diesel engine.
Power Windows and Other Power
Options
Circuit breakers in the fuse panel protect the power
windows and other power accessories. When the current
load is too heavy, the circuit breaker opens. This
protects the circuit until the current load returns to normal
or the problem is fixed.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers,
maxi-fuses and fusible links. This greatly reduces the
chance of a fire caused by an electrical problem. There
may be a fuse taped to the wiring harness near the
hydraulic brake booster.
Instrument Panel Fuse Block
There are two instrument panel fuse blocks located
behind the instrument panel on the passenger side of
the vehicle.
Be sure to replace fuses with fuses of the same rating.
Do not use fuses of higher amperage than those
indicated on the fuse block.

Both underhood fuse blocks are located in the engine
compartment, on the passenger side of the vehicle.To access the fuse blocks, gently squeeze both sides of
the cover to unlatch the tabs at the top. Then, unsnap
both attachments at the bottom and remove the cover.
Notice:Spilling liquid on any electrical components
on your vehicle may damage it. Always keep the
covers on any electrical component.
Be sure to replace fuses with fuses of the same rating.
Do not use fuses of higher amperage than those
indicated on the fuse block.
