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.

•The gearshift lever must be in P (Park)or N (Neutral) in order for the starterto operate.
•Try operating the starter switch severaltimes. This operation may cleanpotentially corroded contacts or makethe switch temporarily operable untilyou can reach the dealer.
•If all electrical connections are tightand you need assistance to start, SeeJump Starting the Vehicle (page 190).
If engine cranks but won’t start
Prolonged starter cranking (in excess of 10seconds) could cause damage to thestarter motor or the high-pressure fuelpump.
•Check the fuel gauge. You may be outof fuel. If the gauge shows that thereis fuel in the tank, the trouble may bein the electrical system or the fuelsystem. If equipped with an auxiliarytank, be sure that the tank controlswitch is set for the tank with fuel andnot on an empty tank.
•Leaving your ignition key turned to onfor over two minutes without startingmay make starting difficult becausethe glow plugs will cease activation.Reset the system by turning the ignitionkey to off and then back to on again.
Note:If the system is out of fuel and theengine will not start, do not continuecranking the engine. Continued cranking candamage the high-pressure fuel pump.
If the engine runs hot
The following could cause the engine tooverheat:
•Lack of coolant
•Dirty cooling system.
•Plugged radiator fins, A/C condenserand/or oil cooler
•Malfunctioning fan drive
•Driving with frozen coolant
•Sticking thermostat
•Overloading or pulling heavy trailersduring hot weather
•Grill or radiator air blockage
•Slipping or missing drive belt
•Plugged or very dirty air filter
If fuses burn out
WARNING: Replacement fuses andcircuit breakers must always be thesame rating as the original equipmentshown. Never replace a fuse or circuitbreaker with one of a higher rating.Higher rated fuses or circuit breakerscould allow circuit overloading in theevent of a circuit malfunction, resultingin severe vehicle damage or personalinjury due to fire.
Burned-out or blown fuses usually indicatean electrical short-circuit, although a fusemay occasionally burn out from vibration.Insert a second fuse. If this fuseimmediately burns out and you cannotlocate the cause, return your vehicle toyour dealer for a circuit check. SeeChanging a Fuse (page 211).
Selective catalytic reduction systemspeed limit and Idle-only modes
If the vehicle’s speed is limited or in anidle-only mode, the selective catalyticreduction system may be limiting thevehicle’s functions due to low orcontaminated DEF. Check the DEF. SeeSelective Catalytic Reductant System(page 120).

Cold Weather Starting
WARNING: Do not use startingfluid, for example ether, in the air intakesystem. Such fluid could causeimmediate explosive damage to theengine and possible personal injury.
WARNING: Do not mix diesel withgasoline, gasohol or alcohol. This couldcause an explosion.
We recommend using the engine blockheater for starting when the ambienttemperature is at or below -9°F (-23°C).See Engine Block Heater (page 105).
When operating in cold weather, you canuse Motorcraft® cetane improvers ornon-alcohol-based cetane improvers froma reputable manufacturer as needed.
Do not crank the engine for more than 10seconds as starter damage may occur. Ifthe engine fails to start, turn the key to theoff position and wait 30 seconds beforetrying again.
Your vehicle may come with a coldweather starting strategy that preventssevere engine damage by assisting inengine lubrication warm-up. In extremelycold ambient temperatures, this strategyactivates and prevents the acceleratorpedal use for 30 seconds after startingyour vehicle. A message appears in theinformation display as your vehicle warmsup. By not allowing the accelerator pedaluse, the engine oil can properly lubricatethe bearings preventing engine damagedue to lack of proper lubrication. After the30 second warm-up period, theaccelerator pedal is operational again anda message appears informing you that yourvehicle is ready to drive.
When starting the engine in extremely coldtemperatures, for example -15°F (-26°C),we recommend you allow the engine toidle for several minutes before driving yourvehicle.
Illuminates when you switch theignition on as part of thepre-starting system.
1.Turn the key to the on position withoutturning the key to the start position. Donot start the engine until the wait tostart indicator turns off.
2.When the wait to start indicator turnsoff, turn the key to the start positionand release the key as soon as theengine starts. Once the engine starts,the glow plugs may remain on for aperiod. If you attempt to start theengine before the glow plug activationtime ends, but it fails to start, reset theglow plugs by turning the key to the offposition.
3.Once the engine starts, allow it to idlefor about 15 seconds. This is to protectthe engine. Do not increase enginespeed until the oil pressure gaugeindicates normal pressure.
SWITCHING OFF THE ENGINE
Allow the engine to idle for three to fiveminutes before shutting it down. The largerthe engine, the greater the need is for thisidling period.
Note:Try to limit engine idle to 10 minutes.Excessive idling reduces fuel economy.

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.
