Rear Axle Maintenance
A rear axle fluid change or level check is
not required unless a leak is suspected 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), change
the rear axle fluid every 24,000 mi (38,000
km) or three months, whichever comes
first.
California Fuel Filter Replacement
If you register your vehicle in California, the
California Air Resources Board has
determined that the failure to perform this
maintenance item does not nullify the
emission warranty or limit recall liability
before the completion of your vehicle's
useful life. Ford Motor Company, however,
urges you to have all recommended
maintenance services performed at the
specified intervals and to record all vehicle
service.
Hot Climate Oil Change Intervals
The normal oil change interval is 3000
miles (5000 kilometers) for gasoline
vehicles operating in the Middle East, North
Africa, Sub-Saharan Africa or locations
with similar climates using American
Petroleum Institute (API) oils Certified for
Gasoline Engines and displaying the API
Certification Mark. If API Certified Oils are
not available, then it is acceptable to use
API SM or SN oils. If API oils are not
available, then the oil change interval is
1800 miles (3000 kilometers).
Engine Air Filter Replacement
The life of the engine air filter is dependent
on exposure to dusty and dirty conditions.
Vehicles operated in these conditions
require frequent inspection and
replacement of the engine air filter and
cabin air filter.
Diesel Particulate Filter
The filter may need to be removed for ash
cleaning at approximately 120000 miles
(192000 kilometers) or greater (actual
mileage can vary greatly depending upon
engine and vehicle operating conditions)
and replaced with a new or
re-manufactured (ash cleaned) part. The
filter may need to be replaced at
approximately 250000 miles (400000
kilometers) depending upon engine and
vehicle operating conditions. In both cases,
the engine control system sets a service
light (wrench icon) to inform you to bring
your vehicle to the dealer for service. If
there are any issues with the oxidation
catalyst or particulate filter system, a
service light (wrench or engine icon) sets
by the engine control system to inform you
to bring your vehicle into a dealer for
service.
