2017 FORD F450 SUPER DUTY service interval

Vehicles with engines configured for usewith high sulfur diesel fuel are onlyavailable for sale in countries where ultralow sulfur diesel fuel is generally notavailable or mandated by the government.Vehicles originally sold in a ultra low sulfurdiesel fuel market that are subsequentlyexported to non- ultra low sulfur diesel fuelmarkets will need to be retrofitted (at thecustomer’s expense using Ford authorizeddealer service parts) in order to be reliablyoperated on non- ultra low sulfur dieselfuel.
Biodiesel
WARNINGS
Do not use home heating oil,agricultural fuel, raw fats and oils,waste cooking greases, biodieselfuels greater than 20% or any diesel fuelnot intended for highway use. Damage tothe fuel injection system, engine andexhaust catalyst can occur if an improperfuel is used. Do not add gasoline, gasoholor alcohol to diesel fuel. This practicecreates a serious fire hazard and engineperformance problems.
Do not mix diesel fuel with gasoline,gasohol or alcohol. This could causean explosion resulting in personalinjury.
Do not add gasoline, gasohol oralcohol to diesel fuel. This practicecreates a serious fire hazard resultingin personal injury and engine performanceproblems.
Do not use home heating oil or anydiesel fuel not intended for highwayuse. Damage to the fuel injectionsystem, engine, exhaust catalyst and dieselparticulate filter can occur if an improperfuel is used. Red dye is used to identifyfuels intended for agricultural andnon-highway use.
You may operate your vehicle on dieselfuels containing up to 20% biodiesel, alsoknown as B20.
Biodiesel fuel is a chemically convertedproduct from renewable fuel sources, suchas vegetable oils, animal fats and wastecooking greases.
To help achieve acceptable engineperformance and durability when usingbiodiesel in your vehicle:
•Confirm the biodiesel content of thefuel to be B20 (20% biodiesel) or less
•Only use biodiesel fuel of good qualitythat complies with industry standards
•Follow the recommended servicemaintenance intervals. SeeScheduled Maintenance (page 573).
•Do not store biodiesel fuel in the fueltank for more than 1 month
•Consider changing brands or reducingbiodiesel content if you have coldtemperature fuel gelling issues or afrequent LOW FUEL PRESSUREmessage appearing
•Do NOT use raw oils, fats or wastecooking greases
Use of biodiesel in concentrations greaterthan 20% may cause damage to yourvehicle, including engine and/or exhaustafter-treatment hardware (exhaustcatalyst and particulate filter) failures.Concentrations greater than 20% can alsocause fuel filter restrictions that may resultin a lack of power or damage to fuelsystem components, including fuel pumpand fuel injector failures.
SAE 5W-40 or SAE 15W-40 oil isrecommended for fuels with greater than5% biodiesel (B5). Refer to the Specialoperating conditions section under theSchedule Maintenance chapter for moreinformation about oil change intervals andother maintenance when operating onbiodiesel.

Fuel and Refueling

•Front wheel toe may requirere-adjustment to prevent prematureuneven tire wear. Specifications are inthe Ford Workshop Manual.
•Headlight aim may requirere-adjustment.
•The tire air pressures recommendedfor general driving are on the vehicle’sSafety Certification Label. Themaximum cold inflation pressure forthe tire and associated load rating ison the tire sidewall. Tire air pressuremay require re-adjustment within thesepressure limits to accommodate theadditional weight of the snowplowinstallation.
•Federal and some local regulationsrequire additional exterior lamps forsnowplow-equipped vehicles. Consultyour authorized dealer for additionalinformation.
Operating the Vehicle with theSnowplow Attached
Note:Do not use your vehicle for snowremoval until you have driven at least500 mi (800 km).
Ford recommends vehicle speed does notexceed 45 mph (72 km/h) whensnowplowing.
The attached snowplow blade restrictsairflow to the radiator, and may cause theengine to run at a higher temperature:Attention to engine temperature isespecially important when outsidetemperatures are above freezing. Anglethe blade to maximize airflow to theradiator and monitor engine temperatureto determine whether a left or right angleprovides the best performance.
Follow the severe duty schedule in yourScheduled Maintenance information forengine oil and transmission fluid changeintervals.
Snowplowing with your AirbagEquipped Vehicle
WARNINGS
Do not attempt to service, repair, ormodify the airbag supplementalrestraint system (SRS) or its fuses.Contact an authorized dealer.
Additional equipment for examplesnowplow equipment may affect theperformance of the airbag sensorsincreasing the risk of injury. Please refer tothe Body Builders Layout Book forinstructions about the appropriateinstallation of additional equipment.
All occupants of the vehicle,including the driver, should alwaysproperly wear their seatbelt, evenwhen provided with an airbagsupplemental restraint system (SRS).
Your vehicle is equipped with a driver andpassenger airbag supplemental restraintsystem. The supplemental restraint systemwill activate in certain frontal and offsetfrontal collisions when the vehicle sustainssufficient frontal deceleration.
Careless or high speed driving whileplowing snow that results in sufficientvehicle decelerations can deploy theairbags. Such driving also increases the riskof accidents.
Never remove or defeat the trippingmechanisms designed into the snowremoval equipment by its manufacturer.Doing so may cause damage to the vehicleand the snow removal equipment as wellas possible airbag deployment.
Engine temperature while plowing
When driving with a plow, your engine mayrun at a higher temperature than normalbecause the attached snowplow blade willrestrict airflow to the radiator.

Driving Hints

If your vehicle is equipped with a dieselengine, an Intelligent Oil Life Monitor™calculates the proper oil change serviceinterval. When the information displayindicates: OIL CHANGE REQUIRED, changethe engine oil and oil filter. SeeInformation Displays (page 111).
The engine oil filter protects your engineby filtering harmful, abrasive or sludgeparticles and particles significantly smallerthan most available will-fit filters. SeeMotorcraft Parts (page 419).
1. Unscrew the oil filter and oil pan drainplug and wait for the oil to drain.
2. Replace the filter.
3. Reinstall the oil pan drain plug.
4. Refill the engine with new oil. SeeCapacities and Specifications (page427).
5. For diesel engines, you need to resetthe Intelligent Oil Life Monitor™. SeeInformation Displays (page 111).

Maintenance

Coolant Change
At specific mileage intervals, as listed inthe scheduled maintenance information,the coolant should be changed. Theinformation display may display a messageto change coolant at this time. Addprediluted coolant approved to the correctspecification. See Capacities andSpecifications (page 415).
Engine-driven Cooling Fan (FanClutch)
Your vehicle may have an engine drivencooling fan drive (also called a fan clutch).This fan drive changes the fan speed tomatch the vehicle’s changing cooling airflow requirements. Fan speed, fan noiselevel and fuel consumption all will increasebased on the driving conditions thatinclude trailer towing, hill climbing, heavyloads, high speed and high ambienttemperature, individually or in combination.
The fan drive is designed to provide theminimum fan speed (and resultingminimum fan noise and fuel consumption)required to meet the ever changing vehiclecooling air flow requirements. You will hearthe amount of fan noise increasing anddecreasing as the engine powerrequirements and vehicle driving conditionschange as you drive. This is to be expectedas being normal to the operation of yourvehicle. High levels of fan noise might alsobe heard when your engine is first started,and should normally decrease after drivingfor a short time.
AUTOMATIC TRANSMISSION
FLUID CHECK
Have an authorized dealer check andchange the transmission fluid and filter atthe correct service interval. SeeScheduled Maintenance (page 573).
Do not use supplemental transmissionfluid additives, treatments or cleaningagents. The use of these materials mayaffect transmission operation and resultin damage to internal transmissioncomponents.
Checking Automatic TransmissionFluid
For scheduled intervals of the fluid checksand changes, See ScheduledMaintenance (page 573). Yourtransmission does not consume fluid.However, the fluid level should be checkedif the transmission is not working properly,i.e., if the transmission slips or shifts slowlyor if you notice some sign of fluid leakage.
Automatic transmission fluid expandswhen warmed. To obtain an accurate fluidcheck, drive the vehicle until it is at normaloperating temperature (approximately19 mi (30 km)). Verify that thetransmission fluid temperature gauge,located on the instrument cluster, is withinnormal range.
1. Drive the vehicle 19 mi (30 km)until itreaches normal operating temperature.
2.Park the vehicle on a level surface andengage the parking brake.
3.With the engine running, parking brakeengaged and your foot on the brakepedal, move the gearshift lever throughall of the gear ranges. Allow sufficienttime for each gear to engage.
4.Latch the gearshift lever in P and leavethe engine running.
5. Remove the dipstick, wiping it cleanwith a clean, dry lint free rag. Ifnecessary, refer to the Under HoodOverview in this chapter for thelocation of the dipstick.
