EXCEPTIONS
In addition, there are several exceptions to the Normal Schedule. They
are listed below:
COOLANT CHANGE RECORD
Normal Vehicle Axle Maintenance
❑Rear axles and power take-off (PTO) units containing synthetic lubricant and light duty trucks equipped with Ford-design
axles are lubricated for life. These lubricants are not to be checked or changed unless a leak is suspected, service is re-
quired or the axle assembly has been submerged in water. The axle and PTO lubricant should be changed anytime the axle
and PTO have been submerged in water. Non-synthetic rear axle lubricants should be replaced every 3,000 miles
(5,000 km) or 3 months, whichever occurs first, during extended trailer tow operation above 70°F (21°C) ambient and
wide open throttle for extended periods above 45 mph (72 km/h). The 3,000 mile (5,000 km) lube change interval may
be waived if the axle was filled with 75W140 synthetic gear lubricant meeting Ford specification WSL-M2C192-A, part
number F1TZ-19580-B or equivalent. Add four ounces (118 mL) of additive friction modifier C8AZ-19B546-A (EST-
M2C118-A) or equivalent for complete refill of Traction-Lok rear axles. The axle lubricant should be changed anytime an
axle has been submerged in water.
F-450 and F-550 Axle Maintenance
❑Replace rear axle lubricant every 100,000 miles (160,000 km) under normal driving conditions on all F-450 and F-550
commercial applications. For F-450 and F-550 trucks operated at or near maximum Gross Vehicle Weights, the rear axle
lubricant should be replaced 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.
Engine Coolant
❑6 years or 105,000 miles (168,000 km) - change coolant (whichever comes first) or as indicated from the coolant tests
for concentration (freeze-point) or additive strength (corrosion inhibitor).
❑After initial change - change coolant every 3 years or 45,000 miles (72,000 km) or as indicated from the coolant tests
for concentration (freeze-point) or additive strength (corrosion inhibitor).
