²If your vehicle is equipped
with the 7.3L Power Stroke
engine,it will be necessary to
remove the air filter element from
the filter housing by moving the
exposed end of the filter element
down and to the rear of the
vehicle, then lifting the other end
of the filter element up and out
of the engine compartment.
²If your vehicle is equipped with the Cummins B engine,a
secondary air filter is located the bottom of the air filter housing to
keep dirt and debris from falling into the engine when the air filter
element is being removed. This secondary filter needs to be replaced
only after the primary air filter element has been replaced several
times. If necessary replace the secondary air filter.
5. Reach inside the air filter housing and clean the outlet tube where it
extends into the housing. Be sure not to damage the tube because the
air filter element seals around this surface.
6. Check to be sure that the drain hole in the air filter housing is open
and clear of any dirt and debris.
7. Check to be sure the new air filter element is not damaged, then
install it. Make sure there is a tight seal (apply pressure at the outer rim
of the element, not the flexible center).
8. Align the air filter cover latches with the holes in the air filter housing
and install the cover.

SERVICING YOUR WHEELS AND TIRES
Wheel assembly
Your vehicle is fitted with hub
piloted wheels and two-element
swiveling lug nuts (20 & 22 mm).
Do not use taper type wheels or ball
seat wheel nuts.
²Do not paint the mating face of the hub/drum.
²Do not paint the two-element swiveling lug nuts or wheel stud.
²Do not allow an excessive thickness of paint to build between the disc
wheel mounting surfaces.
²Do not install disc wheels where the paint has not fully cured.
²At wheel changes, ensure mounting faces are clean and free of rust,
dirt and excess paint.
If fasteners are needed, use only Ford recommended replacement parts.
²To maintain the desired
torque/tension relation between
nut body and flange, it is
necessary to use clean engine oil
meeting Ford specification
WSS-M2C153-G between nut body and flange. Lubricate the nut body
and flange any time a wheel is removed.
The M20 & M22 wheel nuts are right-hand threads. Refer to the

procedures.
ESSENTIALS OF GOOD FUEL ECONOMY
Measuring techniques
Your best source of information about actual fuel economy is you, the
driver. You must gather information as accurately and consistently as
possible. Fuel expense, frequency of fillups or fuel gauge readings are NOT
accurate as a measure of fuel economy. We do not recommend taking fuel
economy measurements during the first 1 600 km (1 000 miles) of driving
(engine break-in period). You will get a more accurate measurement after
3 000 km±5 000 km (2 000 miles-3 000 miles).
The advertised fuel capacity of the fuel tank(s) on your vehicle is equal
to the rated refill capacity of the fuel tank(s) as listed inFuel Tank
Capacitiesin theCapacities and Specificationschapter. The
advertised capacity is the amount of the Indicated Capacity and the
Empty Reserve combined. Indicated Capacity is the difference in the
amount of fuel in a full tank and a tank when the fuel gauge indicates
empty. Empty Reserve is the small amount of usable fuel remaining in
the fuel tank after the fuel gauge indicates empty.

For troubleshooting information, refer to the engine operator's manual.
If fuses burn out
Burned-out or ªblown-outº fuses or circuit breaker tripping (if equipped)
usually indicate an electrical short circuit, although a fuse may
occasionally fail from vibration. Insert a second fuse or reset the breaker
(if equipped). If this fuse immediately burns out or the breaker (if
equipped) trips and you cannot locate the fuse, return your vehicle to
your dealer for a circuit check.
If lamp bulbs burn out
Repeated lamp burn-out usually indicates a loose connection, either at
the lamp socket, the system ground or a malfunctioning voltage
regulator. If examination does not indicate the cause of the trouble,
return your vehicle to your dealer for inspection.
If headlamps flash on and off
If headlamps flash on and off at regular intervals, the system circuit
breaker (if equipped) is operating, indicating a short circuit or overload.
Take your vehicle to your dealer for a circuit check.
CLEANING AND CARING FOR YOUR VEHICLE
Refer to the Customer Assistance chapter for a list of Ford-approved
cleaners, polishes and waxes.
Washing your vehicle
