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. 337 F-650/750 (TBC) , enUSA, First Printing Scheduled Maintenance
