•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 Guide.
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.
If the engine runs hot
The following could cause the engine to overheat:
•Lack of coolant.
•Dirty cooling system.
•Plugged radiator fins, A/C condenser and/or oil cooler.
•Malfunctioning fan drive.
•Driving with frozen coolant.
•Sticking thermostat.
•Overloading or pulling heavy trailers during hot weather.
•Grill or radiator air blockage.
•Slipping or missing drive belt.
•Plugged or very dirty air filter.

Towing a trailer or using a camper or car-top carrier
As required Change engine oil and filter as indicated by
message center and perform services listed in
the scheduled maintenance chart
Every 15,000 miles
(24,000 km) or 600
engine hoursInspect concentration (freeze-point
protection) and additive strength (corrosion
inhibitor); add engine coolant additive, if
required
Every 15,000 miles
(24,000 km),
6 months, 600 engine
hours or as indicated
by message centerReplace engine- and frame-mounted fuel filters
Every 30,000 miles
(48,000 km)Replace wheel bearing grease/grease seals if
non-sealed bearings are used (2WD vehicles)
Every 60,000 miles
(96,000 km)Change transfer case fluid (4WD vehicles)
Every 60,000 miles
(96,000 km) or 2,400
engine hoursFlush and refill engine coolant; do not add
engine coolant additive
Perform the services noted in the preceding table at the specified
time/mileage (km) period either within 3,000 miles (4,800 km) of the
OIL CHANGE REQUIRED message appearing in the message center or
when the time/mileage (km) reading indicates service is due.
Example #1:The OIL CHANGE REQUIRED message comes on at
19,751 miles (31,786 km); perform the 22,500 mile (36,000 km) fuel
filter replacement.
Example #2:The OIL CHANGE REQUIRED message hasnotcome on
but the odometer reads 22,500 miles (36,000 km); perform the fuel filter
replacement. (i.e., Intelligent Oil Life Monitor™ was reset at 15,000 miles
[24,000 km].)
Note:When adding coolant additive, do not exceed the specified
maximum of 48 fl. oz. (1.4L). Operating the engine with excessive
coolant additive may cause overheating which could lead to severe
permanent engine damage.
Note:After initial coolant flush and fill at 60,000 miles (96,000 km) or
2,400 engine hours, flush and fill every 45,000 miles (72,000 km) or
1,800 engine hours thereafter.

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 3,000 miles (4,800 km) 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 toMaintenance product specifications and capacitiesin
theMaintenance and Specificationschapter for details).
F-450 and F-550 axle maintenance:Change rear axle fluid every
100,000 miles (160,000 km) 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 50,000 miles
(80,000 km). In addition, this 50,000 mile (80,000 km) 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 120,000 miles (192,000 km) 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 250,000 miles
(400,000 km) 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.
