Warnings
WARNING: Throughout this guide,you will find warnings identified by thewarning symbol. Warnings remind youto be especially careful to reduce the riskof personal injury.
Diesel Engine Information
The diesel engine fuel system is apressurized two-stage filtration systemand consists of:
•A frame-mounted Fuel and WaterSeparator primary filter with an electricfuel pump and water drain
•An engine-mounted secondary fuelfilter
•A fuel injector for each cylinder (8total)
•A high-pressure fuel pump
•A high-pressure fuel rail for eachcylinder bank (2 total)
•Numerous high-pressure pipes fromthe high-pressure pump to the rails,and rails to the injectors
The fuel and water separator removesboth water and impurities from the fuel.The engine-mounted filter filters finerimpurities from the diesel fuel. Theengine-mounted fuel filter and theframe-mounted fuel filter should bechanged at the recommended serviceinterval or when indicated by theinformation display LOW FUEL PRESSUREmessage. See Scheduled Maintenance(page 325).
The fuel and water separator should bedrained at regular intervals (recommendedat every oil change) or when indicated bythe information display and water in fuelindicator light. See Fuel Quality (page108).
Proper fuel filter maintenance and promptwater draining when the water in fuel lightilluminates is essential to prevent injectionequipment damage. Ignoring the water infuel light or the information displaymessage WATER IN FUEL DRAIN FILTERcan cause your vehicle to go into a reducedpower mode.
A frame-mounted electric fuel pumplocated inside the fuel and water separatordraws fuel from the fuel tank to providepressurized fuel to the engine. The fuelpump contains a pressure relief valve foroverpressure protection in the event ofrestricted flow.
The fuel injection system is controlledthrough the powertrain control module.
Engine Protection Mode
Ford diesel engines are equipped withengine protection and emission controlsystems. These systems monitor criticaltemperatures and pressures, and modifyengine operation accordingly. Thesemodified engine performancecharacteristics are normal.

If these modified engine performancecharacteristics persist for an extendedperiod and either the service engine soonor powertrain malfunction, reduced power,electronic throttle control light isilluminated, have the system checked byan authorized dealer.
Service engine soon
Powertrain malfunction, reducedpower, electronic throttle control
Diesel Lubrication System
It is important to change the engine oil atthe recommended service intervals orwhen indicated by the information displayto maintain oil viscosity. Extending the oiland filter change interval beyond therecommended interval can negativelyaffect engine performance, fuel economyand engine life. See Engine Oil Check(page 227).
Engine and secondary cooling system
The cooling system contains a primarycooling loop to cool the engine and asecondary cooling loop to cool thetransmission, charge air, and fuel. Thecoolant serves three primary purposes: toprovide heat transfer, freeze pointprotection, and corrosion protection usingadditives.
Vehicles with diesel engines typically areused to carry heavy loads and accumulatemileage rapidly. These two factors maycause the additives in the coolant to wearout in a shorter time. You can find moreinformation about coolant additives andcoolant change intervals in the coolantchapter. See General MaintenanceInformation (page 325). Operating theengine with insufficient coolant or coolantadditive can cause severe engine damage.
Selective catalytic reduction system
Your vehicle is equipped with a selectivecatalytic reduction system designed toreduce emission levels of nitrogen oxidesfrom the exhaust of your diesel engine. Thissystem relies on the use of Diesel ExhaustFluid (DEF) that you must replenish atcertain intervals. Failure to maintain properDEF levels or if the DEF becomescontaminated will result in vehicle speedlimitations or result in your vehicle enteringan idle-only mode. See SelectiveCatalytic Reductant System (page 120).
Minor Troubleshooting Guide
If the engine won’t crank
WARNING: Battery posts,terminals and related accessoriescontain lead and lead compounds. Washhands after handling.
Turn on the headlights. If the lights are dim,do not go on at all or when the ignition isturned to the start position, the lightsbecome dim or go out, the batteryconnections may be loose or corroded, orthe battery may be discharged. If there isa clicking or stuttering sound coming fromthe engine compartment when you turnthe key to the start position, this may alsoindicate a loose or corroded batteryconnection.
Check the battery connections at thebattery posts, cable connection to theengine grounding point and at the starterconnection.
If you suspect a discharged battery, haveit checked and corrected.

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 325).
•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.
Look for a label on the fuel pump toconfirm the amount of biodiesel containedin a diesel fuel. Biodiesel content is oftenindicated with the letter B followed by thepercent of biodiesel in the fuel. Forexample, B20 indicates a fuel containing20% biodiesel. Ask the service stationattendant to confirm the biodiesel contentof a diesel fuel if you do not see a label onthe fuel pump.
Biodiesel fuels degrade more easily thandiesel fuels not containing biodiesel andshould not be stored in the fuel tank formore than 1 month. If you plan to park orstore your vehicle for more than 1 month,then you should empty your vehicle fueltank of biodiesel fuel. You should fill thetank with a pure petroleum-based dieselfuel and run your vehicle for a minimum of30 minutes.
Note:Degraded or oxidized biodiesel candamage fuel system seals and plastics andcorrode steel parts.
During cold weather, if you have problemsoperating on biodiesel, you may need touse a diesel fuel with lower biodieselcontent, try another brand, or discontinuethe use of biodiesel.
Diesel Fuel Additives
It should not be necessary to add anyaftermarket additives to your fuel if youuse a high quality diesel fuel that conformsto ASTM industry specifications.Aftermarket additives can damage the fuelinjector system or engine.
Use Motorcraft® cetane booster or anequivalent cetane booster additive if yoususpect fuel has low cetane. UseMotorcraft® anti-gel & performanceimprover or an equivalent additive if thereis fuel gelling.

Illumination of the service engine soonindicator, charging system warning light orthe temperature warning light, fluid leaks,strange odors, smoke or loss of enginepower could indicate that the emissioncontrol system is not working properly.
An improperly operating or damagedexhaust system may allow exhaust toenter the vehicle. Have a damaged orimproperly operating exhaust systeminspected and repaired immediately.
Do not make any unauthorized changes toyour vehicle or engine. By law, vehicleowners and anyone who manufactures,repairs, services, sells, leases, tradesvehicles, or supervises a fleet of vehiclesare not permitted to intentionally removean emission control device or prevent itfrom working. Information about yourvehicle’s emission system is on the VehicleEmission Control Information Decallocated on or near the engine. This decalalso lists engine displacement.
Please consult your warranty informationfor complete details.
On-Board Diagnostics (OBD-II)
Your vehicle has a computer known as theon-board diagnostics system (OBD-II) thatmonitors the engine’s emission controlsystem. The system protects theenvironment by making sure that yourvehicle continues to meet governmentemission standards. The OBD-II systemalso assists a service technician in properlyservicing your vehicle.
When the service engine soonindicator illuminates, the OBD-IIsystem has detected amalfunction. Temporary malfunctions maycause the service engine soon indicator toilluminate. Examples are:
1.Your vehicle has run out of fuel—theengine may misfire or run poorly.
2.Poor fuel quality or water in thefuel—the engine may misfire or runpoorly.
3.The fuel fill inlet may not have closedproperly. See Refueling (page 112).
4.Driving through deep water—theelectrical system may be wet.
You can correct these temporarymalfunctions by filling the fuel tank withgood quality fuel, properly closing the fuelfill inlet or letting the electrical system dryout. After three driving cycles without theseor any other temporary malfunctionspresent, the service engine soon indicatorshould stay off the next time you start theengine. A driving cycle consists of a coldengine startup followed by mixed city andhighway driving. No additional vehicleservice is required.
If the service engine soon indicator remainson, have your vehicle serviced at the firstavailable opportunity. Although somemalfunctions detected by the OBD-II maynot have symptoms that are apparent,continued driving with the service enginesoon indicator on can result in increasedemissions, lower fuel economy, reducedengine and transmission smoothness andlead to more costly repairs.
Readiness for Inspection andMaintenance (I/M) Testing
Some state and provincial and localgovernments may haveInspection/Maintenance (I/M) programsto inspect the emission control equipmenton your vehicle. Failure to pass thisinspection could prevent you from gettinga vehicle registration.
If the service engine soonindicator is on or the bulb doesnot work, your vehicle may needservice. See On-Board Diagnostics.
