Engine coolant change interval
Initial change 6 years or 100,000 miles (160,000 km)
(whichever comes first), or as indicated from the
coolant tests for concentration (freeze-point) or
additive strength (corrosion inhibitor)
After initial change Every 3 years or 50,000 miles (80,000 km), or as
indicated from the coolant tests for concentration
(freeze-point) or additive strength (corrosion
inhibitor)
Use engine coolant specified in theMaintenance product
specifications and capacitiestable in theMaintenance and
Specificationschapter
Refer toSpecial operating conditionslater in this chapter
Check every month
Engine air filter restriction gauge
Fuel filter/water separator; drain if necessary (or if indicated by the
message center)
Holes/Slots in the tail pipe to make sure they are functional and clear
of debris
Retightening lug nuts*
Vehicles with single
rear wheelsRetighten the lug nuts to the specified torque at
500 miles (800 km) after any wheel disturbance
(tire rotation, changing a flat tire, wheel removal,
etc).
Vehicles with dual
rear wheelsRetighten the wheel lug nuts to the specified
torque at 100 miles (160 km), and again at
500 miles (800 km) of new vehicle operation and
after any wheel disturbance (tire rotation,
changing a flat tire, wheel removal, etc).
*Refer toWheel lug nut torque specificationsin yourOwner’s Guide
for the proper lug nut torque specification

NORMAL SCHEDULED MAINTENANCE AND LOG
Intelligent Oil Life Monitor™
Your vehicle is equipped with an Intelligent Oil Life Monitor™ that
determines when the engine oil should be changed based on how your
vehicle is used. By using several important factors in its calculations, the
monitor helps reduce the cost of owning your vehicle and reduce
environmental waste at the same time. This means you won’t have to
remember to change the oil on a mileage-based schedule; the vehicle lets
you know when an oil change is due by displaying OIL CHANGE
REQUIRED in the message center. The following table is intended to
provide examples of vehicle use and its impact on engine oil change
intervals; it is provided as a guideline only. Actual engine oil change
intervals will depend on several factors and will generally decrease with
severity of use.
When to expect the OIL CHANGE REQUIRED message
Miles (km) Vehicle use and examples
7500-10000
(12000-16000)Normal
– Normal commuting with highway driving
– No, or moderate, load/towing
– Flat to moderately hilly roads
– No extended idling
5000-7499
(8000-11999)Severe
– Moderate to heavy load/towing
– Mountainous or off-road conditions
– Extended idling
– Extended hot or cold operation
3000-4999
(4000-7999)Extreme
– Maximum load/towing
– Extreme hot or cold operation
– Use of high sulfur diesel fuel
Use the appropriate special operating condition for maintenance
information when using high sulfur diesel fuels, operating your vehicle
off-road or in dusty conditions (such as unpaved roads)

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.
