Coolant Change
At specific mileage intervals, as listed in
the scheduled maintenance information,
the coolant should be changed. The
information display may display a message
to change coolant at this time. Add
prediluted coolant approved to the correct
specification. See Capacities and
Specifications (page 411).
Engine-driven Cooling Fan (Fan
Clutch)
Your vehicle may have an engine driven
cooling fan drive (also called a fan clutch).
This fan drive changes the fan speed to
match the vehicle ’s changing cooling air
flow requirements. Fan speed, fan noise
level and fuel consumption all will increase
based on the driving conditions that
include trailer towing, hill climbing, heavy
loads, high speed and high ambient
temperature, individually or in combination.
The fan drive is designed to provide the
minimum fan speed (and resulting
minimum fan noise and fuel consumption)
required to meet the ever changing vehicle
cooling air flow requirements. You will hear
the amount of fan noise increasing and
decreasing as the engine power
requirements and vehicle driving conditions
change as you drive. This is to be expected
as being normal to the operation of your
vehicle. High levels of fan noise might also
be heard when your engine is first started,
and should normally decrease after driving
for a short time.
AUTOMATIC TRANSMISSION
FLUID CHECK
Have an authorized dealer check and
change the transmission fluid and filter at
the correct service interval. See
Scheduled Maintenance
(page 567). Do not use supplemental transmission
fluid additives, treatments or cleaning
agents. The use of these materials may
affect transmission operation and result
in damage to internal transmission
components.
Checking Automatic Transmission
Fluid
For scheduled intervals of the fluid checks
and changes, See
Scheduled
Maintenance (page 567). Your
transmission does not consume fluid.
However, the fluid level should be checked
if the transmission is not working properly,
i.e., if the transmission slips or shifts slowly
or if you notice some sign of fluid leakage.
Automatic transmission fluid expands
when warmed. To obtain an accurate fluid
check, drive the vehicle until it is at normal
operating temperature (approximately
19 mi (30 km)
). Verify that the
transmission fluid temperature gauge,
located on the instrument cluster, is within
normal range.
1. Drive the vehicle
19 mi (30 km)until it
reaches normal operating temperature.
2. Park the vehicle on a level surface and
engage the parking brake.
3. With the engine running, parking brake
engaged and your foot on the brake
pedal, move the gearshift lever through
all of the gear ranges. Allow sufficient
time for each gear to engage.
4. Latch the gearshift lever in P and leave
the engine running.
5. Remove the dipstick, wiping it clean with a clean, dry lint free rag. If
necessary, refer to the Under Hood
Overview in this chapter for the
location of the dipstick.

Additional Axle Maintenance for Dual
Rear Wheels
Change rear axle fluid every 250,000 miles
(400,000 kilometers) under normal driving
conditions on all commercial applications.
When operating your vehicle at or near
maximum gross vehicle weights, change
the rear axle fluid every 60,000 miles
(96,000 kilometers). In addition, follow
this 60,000 mile (96,000 kilometer)
schedule when operating your vehicle
under the special operating conditions
where noted.
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
Vehicles operating in the Middle East,
North Africa, Sub-Saharan Africa or
locations with similar climates using an
American Petroleum Institute (API)
Certified for Gasoline Engines (Certification
mark) oil of SM or SN quality, the normal
oil change interval is 3000 miles (5000
kilometers). If the available API SM or SN oils are not
available, then the oil change interval is
1800 miles (3000 kilometers).
Engine Air Filter and Cabin Air Filter
Replacement
The life of the engine air filter and cabin 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
remanufactured (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.
