Air filter replacement:
When replacing the air filter element, use the Motorcraft® air filter
element listed inMotorcraft part numbersin theCapacities and
Specificationschapter.
Failure to use the correct air filter element may result in severe
engine damage.
1. Locate the mass air flow sensor
electrical connector on the air inlet
tube. This connector will need to be
unplugged.
Unlock the locking clip on the
connector, then squeeze and pull
the connector off of the air inlet
tube.
2. Release the four clamps that
secure the cover to the air filter
housing. Push the air filter cover
forward (away from you) and up
slightly to release it.
3. Remove the air filter element from the air filter housing.

MINOR TROUBLESHOOTING GUIDE
Air purge procedure
Turn the key on for 30 seconds, then turn off. Repeat the procedure six
times.
If the engine won’t crank
WARNING:Battery posts, terminals and related accessories
contain lead and lead compounds.Wash hands after handling.
Turn on the headlights. If the lights are dim, do not go on at all or when
the ignition is turned to START the lights become dim or go out, the
battery connections may be loose or corroded, or the battery may be
discharged. If there is a clicking or stuttering sound coming from the
engine compartment when you turn the key to START, this may also
indicate a loose or corroded battery connection.
Check the battery connections at the battery posts, cable connection to
the engine grounding point and at the starter connection.
If a discharged battery is suspected, have it checked and corrected.
•The gearshift lever must be in P (Park) or N (Neutral) in order for
the starter to operate.
•Try operating the starter switch several times. Should the switch be
corroded, this operation may clean the contacts or make the switch
temporarily operable until you can reach the dealer.
•If all electrical connections are tight and you need assistance to start,
refer toJump startingin theRoadside Emergencieschapter of your
Owner’s Manual.
If engine cranks but won’t start
Prolonged starter cranking (in excess of 10 seconds) could cause
damage to the starter motor.
•
Check the fuel gauge. You may be out of fuel. If the gauge shows that
there is fuel in the tank, the trouble may be in the electrical system or
the fuel system. If equipped with an auxiliary tank, be sure that the tank
control switch is set for the tank with fuel and not on an empty tank.
•Leaving the ignition key turned to on for over two minutes without
starting may make starting difficult because the glow plugs will cease
activation. Reset the system by turning the ignition key to off and
then back to on again.

ENGINE
Engines are more efficient when they are clean because grease and dirt
buildup keep the engine warmer than normal. When washing:
•Take care when using a power washer to clean the engine. The
high-pressure fluid could penetrate the sealed parts and cause
damage.
•Do not spray a hot engine with cold water to avoid cracking the
engine block or other engine components.
•Spray Motorcraft® Engine Shampoo and Degreaser (ZC-20) on all
parts that require cleaning and pressure rinse clean.
•Never wash or rinse the engine while it is running; water in the
running engine may cause internal damage.
•Cover the highlighted areas to prevent water damage when cleaning
the engine.

EXCEPTIONS
In addition, there are several exceptions to the Normal Schedule. They
are listed below:
Normal vehicle axle maintenance:Rear axles and power take-off
(PTO) units with synthetic fluid and light-duty trucks equipped with
Ford-design axles are lubricated for life; do not check or change fluid
unless a leak is suspected, service is required or the assembly has been
submerged in water. During long periods of trailer towing with outside
temperatures above 70°F (21°C) and at wide-open throttle for long
periods above 45 mph (72 km/h), non-synthetic rear axle fluids should
be changed every 3000 miles (4800 kilometers) or three months,
whichever comes first. This interval can be waived if the axle is filled
with 75W140 synthetic gear fluid meeting Ford specification
WSL-M2C192-A, part number F1TZ-19580-B or equivalent. Add friction
modifier XL-3 (EST-M2C118-A) or equivalent for complete refill of
Traction-Lok rear axles (refer toTechnical specificationsin the
Maintenancechapter for details).
F-450 and F-550 axle maintenance:Change rear axle fluid every
100000 miles (160000 kilometers) under normal driving conditions on all
commercial applications. For trucks operated at or near maximum Gross
Vehicle Weights, the rear axle fluid should be changed every 50000 miles
(80000 kilometers). In addition, this 50000 mile (80000 kilometer)
schedule should be observed when the vehicles are operated under the
special operating conditions, where noted.
Diesel Particulate Filter (DPF):The DPF may need to be removed
for ash cleaning at approximately 120000 miles (192000 kilometers) or
greater (actual mileage can vary greatly depending upon engine/vehicle
operating conditions) and replaced with a new or remanufactured (ash
cleaned) part. The filter may need to be replaced at approximately
250000 miles (400000 kilometers) depending upon engine/vehicle
operating conditions. In both cases the engine control system will set a
service light (
) to inform you to bring the vehicle to the dealer for
service. If there are any issues with the oxidation catalyst/DPF system a
service light (
or) will be set by the engine control system to
inform you to bring the vehicle into a dealership for service.
