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.

How to Interrupt or Cancel OperatorCommanded Regeneration
If you need to cancel the operatorcommanded regeneration, pressing thebrake, accelerator or switching the engineoff stops the procedure. Depending on theamount of time you allowed the operatorcommanded regeneration to operate, sootmay not have had sufficient time to be fullyeliminated, but the exhaust system andexhaust gas may still be hot. If you shutyour vehicle off during operatorcommanded regeneration, you may noticeturbo flutter. This is a normal consequencecaused by shutting off a diesel engineduring boosted operation and is considerednormal.
Filter Service and Maintenance
Over time, a slight amount of ash buildsup in the diesel particulate filter, which isnot removed during the regenerationprocess. The filter may need to be replacedwith a new or remanufactured part atapproximately 250,000 mi (400,000 km).Actual mileage varies depending on engineand vehicle operating conditions.
If filter service is required, theengine control system warninglamp illuminates in theinformation display.
If there are any issues with thediesel particulate filter system,the engine control systemwarning lamp and a serviceengine soon warning lampilluminate to inform you thatyour vehicle requires service. Have yourvehicle checked as soon as possible.
Resonator and Tailpipe AssemblyMaintenance
Aftermarket devices or modifications tothe exhaust system may reduce theeffectiveness of the exhaust system aswell as cause damage to the exhaustsystem or engine. This may also degradevehicle performance and could lead toengine damage that may not be coveredby the vehicle Warranty.

Severe Climates
If you drive in extremely cold climates:
•It may be necessary to increase thecoolant concentration above 50%.
•A coolant concentration of 60%provides improved freeze pointprotection.Coolant concentrationsabove 60% decrease the overheatprotection characteristics of thecoolant and may cause enginedamage.
If you drive in extremely hot climates:
•You can decrease the coolantconcentration to 40%.
•Coolant concentrations below 40%decrease the freeze and corrosionprotection characteristics of thecoolant and may cause enginedamage.
Vehicles driven year-round in non-extremeclimates should use prediluted enginecoolant for optimum cooling system andengine protection.
Coolant Change
At specific mileage intervals, as listed inthe scheduled maintenance information,the coolant should be changed. Theinstrument cluster display may display amessage to change coolant at this time.Add prediluted coolant approved to thecorrect specification. See Capacities andSpecifications (page 291).
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 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 can hearfan noise increasing and decreasing as theengine power requirements and vehicledriving conditions change as you drive. Thisis to be expected as being normal to theoperation of your vehicle. High levels of fannoise might also be heard when yourengine is first started, and should normallydecrease after driving for a short time.

on the road. If a tire is mounted byerror on the wrong-sized rim, donot remount it on the proper rim -scrap it. It may have beendamaged internally (which is notexternally visible) by having beendangerously stretched and couldfail on the highway.
Old valves may leak. When newtubeless tires are mounted,have new valves of the correcttype installed. Tubeless tiresmust only be mounted onwheels designed for tubelesstires i.e., wheels which havesafety humps or ledges.
It is recommended that you haveyour tires and wheels balanced.Tires and wheels, which are notbalanced, may cause steeringdifficulties, a bumpy ride, andirregular tire wear.
Be sure that all your valveshave suitable valve caps. Thevalve cap is the primary sealagainst air loss.
TEMPORARY SPARE TIRES
When using any temporary sparetire, be sure to follow the vehiclemanufacturer’s instructions.
REMEMBER... TO AVOIDDAMAGE TO YOUR TIRES ANDPOSSIBLE ACCIDENT:
•CHECK TIRE PRESSURE ATLEAST ONCE EACH MONTHWHEN TIRES ARE COLD ANDBEFORE LONG TRIPS.

Your vehicle can be driven in such a waythat dilutes and increases the level of oilby short trips that do not allow the engineto get to operating temperature, extendedidling, and low speed driving for longperiods of time.
A message appears in the instrumentcluster display when it is time for an oilchange. Make sure you perform the oilchange within two weeks or 500 mi(800 km) of the message appearing. Makesure you reset the Intelligent Oil-LifeMonitor after each oil change. SeeInstrument Cluster (page 64).
If your instrument cluster display resetsprematurely or becomes inoperative, youshould perform the oil change interval atsix months or 5,000 mi (8,000 km) fromyour last oil change. Never exceed one yearor 10,000 mi (16,000 km) between oilchange intervals for gas engines.
Never exceed one year or 15,000 mi(24,000 km) between oil change intervalsfor diesel engines.
Your vehicle is very sophisticated and builtwith multiple, complex, performancesystems. Every manufacturer developsthese systems using differentspecifications and performance features.That is why it is important to rely upon yourdealership to properly diagnose and repairyour vehicle.
Ford Motor Company has recommendedmaintenance intervals for various partsand component systems based uponengineering testing. Ford Motor Companyrelies upon this testing to determine themost appropriate mileage for replacementof oils and fluids to protect your vehicle atthe lowest overall cost to you andrecommends against maintenanceschedules that deviate from the scheduledmaintenance information.
We strongly recommend the use of onlygenuine Ford, Motorcraft orFord-authorized re-manufacturedreplacement parts engineered for yourvehicle.
Additives and Chemicals
This owner's manual and the FordWorkshop Manual list the recommendedadditives and chemicals for your vehicle.We do not recommend using chemicals oradditives not approved by us as part ofyour vehicle’s normal maintenance. Pleaseconsult your warranty information.
Oils, Fluids and Flushing
In many cases, fluid discoloration is anormal operating characteristic and, byitself, does not necessarily indicate aconcern or that the fluid needs to bechanged. However, a qualified expert, suchas the factory-trained technicians at yourdealership, should inspect discolored fluidsthat also show signs of overheating orforeign material contaminationimmediately.
Make sure to change your vehicle’s oils andfluids at the specified intervals or inconjunction with a repair. Flushing is aviable way to change fluid for many vehiclesub-systems during scheduledmaintenance. It is critical that systems areflushed only with new fluid that is the sameas that required to fill and operate thesystem or using a Ford-approved flushingchemical.
