2011 FORD F450 service

EXCEPTIONS
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 to Maintenance product specifications and capacities in
the Maintenance and Specifications chapter for details).
Police/Taxi/Livery vehicle axle maintenance: Change rear axle fluid
every 100,000 miles (160,000 km). Rear axle fluid change may be waived
if the axle was filled with 75W140 synthetic gear fluid meeting Ford
specification WSL-M2C192-A, part number FITZ-19580-B or equivalent.
Add four ounces (118 mL) of additive friction modifier XL-3
(EST-M2C118-A) or equivalent for complete refill of Traction-Lok rear
axles. The axle fluid should be changed anytime the axle has been
submerged in water.
E–450 and F–450/550 axle maintenance: Change rear axle fluid every
100,000 miles (160,000 km) under normal driving conditions. For
vehicles 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.
California fuel filter replacement: If the vehicle is registered in
California, the California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify the emission
warranty or limit recall liability prior to the completion of the 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.Scheduled Maintenance

Class A Motorhome: Change brake fluid every two years.
Hot climate oil change intervals: If operating conditions are normal
and you drive your vehicle under typical, everyday conditions and you
are using an API performance category oil of SL or later (for example
SM, etc.) then you can follow the 7,500 mile (12,000 km) normal service
oil change intervals schedule. Vehicles operating in the Middle East,
North Africa, Sub-Saharan Africa or locations with similar climates must
follow the oil change interval of 3,000 mile (4,800 km) if the owner is
using oils defined by the American Petroleum Institute (API)
performance category of API SK or earlier (for example SJ, etc).
Edge/MKX AWD only – vehicles operating off-road in sand during high
ambient temperatures must replace the AWD PTU (All-wheel drive
Power Transfer Unit) lube every 20,000 miles (32,000 km).
Engine air filter & cabin air filter replacement: Engine air filter and
cabin air filter life is dependent on exposure to dusty and dirty
conditions. Vehicles operated in these conditions will require frequent
inspection and replacement of the engine air filter and cabin air filter.
ENGINE COOLANT CHANGE RECORD
