CHANGING THE ENGINE AIR
FILTER - 6.7L DIESEL
Air Filter Restriction Gauge
WARNING: To reduce the risk ofvehicle damage and personal burninjuries, do not start your engine with theair cleaner removed and do not removeit while the engine is running.
Note:Operating your vehicle in heavysnowfall or extreme rain conditions mayallow excessive amounts of snow or waterinto the air intake system. This could plugor soak the air filter and cause the engine tolose power or shut down.
The restriction gauge, on the upper housingof the air filter assembly, measures thevacuum inside the air filter. The more theair filter is dirty or clogged, the higher thevacuum reading.
Check the air filter restriction gaugewhenever you open the hood to performgeneral engine maintenance or at leastevery 7,500 mi (12,000 km). If you operateyour vehicle in extremely dusty conditions,check and reset the gauge at least every500 mi (800 km), or two weeks, whichevercomes first. Change the air filter when therestriction gauge reads near the changefilter line and the gauge is yellow. If youallow the restriction gauge to reachmaximum restriction, you can affect yourengine performance and fuel economy.
Note:Do not blow out the air filter elementwith compressed air since the compressedair could damage the filter paper.
Note:Do not rely on filter appearancealone. A filter which appears to be dirty mayhave several thousand miles (kilometers)of life remaining.
After installation of the new filter element,reset the gauge by pressing the resetbutton on top of the gauge.

DRAINING THE FUEL FILTER
WATER TRAP - 6.7L DIESEL
Your vehicle is equipped with a diesel fuelconditioner module located on theframe-rail under the driver-side floorboardnear the transmission.
You should drain water from themodule assembly whenever thewarning light comes on and themessage center directs you to drain thewater separator. This will occur whenapproximately 8.45 fl oz (250 ml) of wateraccumulates in the module. If you allowthe water level to exceed this level, thewater may pass through to the engine andmay cause fuel injection equipmentdamage.
Draining the Diesel FuelConditioner Module (DFCM)
WARNING: Do not drain thewater-in-fuel separator while the engineis running. Failure to follow this warningmay result in fire, serious injury, death orproperty damage.
Note:If you drain the diesel fuel conditionermodule while the system is running air willenter into the fuel system. The engine willnot operate properly if air enters the system.
Note:With fuel tank levels above 3⁄4 tankit may be necessary to loosen the bowl threeturns before opening the drain. This willactuate an anti-siphon valve at the fuel andwater separator inlet and prevent the fuelfrom siphoning out of the tank.
Note:A loose drain valve can allow air toenter the fuel system and cause drivetrainissues. The engine will not operate properly.Be sure that you fully tighten the drain valve.
1.Stop your vehicle and shut off theengine.
2.Locate the diesel fuel conditionermodule and place an appropriatecontainer under the drain port.
234
2024 F-650/750 (TBC) , enUSA, Edition date: 202210, First-PrintingMaintenanceE317619 E163360

3.Rotate the drain counterclockwise untilthe O-ring is visible. Allow the dieselfuel conditioner module to drain forapproximately 25 seconds or untilclean fuel is observed. Rotate the drainclockwise to tighten it. If no liquiddrains, there may be a clog in the drain.Have the conditioner module servicedby an authorized dealer.
4.Make sure that you fully tighten thedrain valve and then remove thecontainer from under your vehicle.
5.Restart the engine. If the Water in FuelDrain Filter message and lightcontinues to illuminate, have the fuelsystem checked and repaired.
ENGINE COOLANT CHECK -
6.7L DIESEL
WARNING: Do not remove thecoolant reservoir cap when the engine ison or the cooling system is hot. Wait 10minutes for the cooling system to cooldown. Cover the coolant reservoir capwith a thick cloth to prevent thepossibility of scalding and slowly removethe cap. Failure to follow this instructioncould result in personal injury.
WARNING: To reduce the risk ofpersonal injury, make sure the engine iscool before unscrewing the coolantpressure relief cap. The cooling systemis under pressure. Steam and hot liquidcan come out forcefully when you loosenthe cap slightly.
When the engine is cold, check theconcentration and level of the coolant atthe intervals listed in the scheduledmaintenance information. See ScheduledMaintenance (page 325).
Note:Make sure that the coolant level isbetween the MIN and the MAX marks onthe coolant reservoir.
Note: Coolant expands when it is hot. Thelevel may extend beyond the MAX mark.
Maintain coolant concentration within48% to 50%, which equates to a freezepoint between -30°F (-34°C) and -34°F(-37°C). Coolant concentration should bechecked using a refractometer. We do notrecommend the use of hydrometers orcoolant test strips for measuring coolantconcentration.
Adding Coolant
WARNING: Do not put coolant inthe windshield washer reservoir. Ifsprayed on the windshield, coolant couldmake it difficult to see through thewindshield.
WARNING: Do not add coolantfurther than the MAX mark.
WARNING: Do not add coolantwhen the vehicle is on or the coolingsystem is hot. Failure to follow thisinstruction could result in personal injury.
WARNING: Do not remove thecoolant reservoir cap when the engine ison or the cooling system is hot. Wait 10minutes for the cooling system to cooldown. Cover the coolant reservoir capwith a thick cloth to prevent thepossibility of scalding and slowly removethe cap. Failure to follow this instructioncould result in personal injury.
Note: Automotive fluids are notinterchangeable. Do not use coolant orwindshield washer fluid outside of itsspecified function and vehicle location.
235
2024 F-650/750 (TBC) , enUSA, Edition date: 202210, First-PrintingMaintenance

Note: Do not use stop leak pellets, coolingsystem sealants, or non-specified additivesas they can cause damage to the enginecooling or heating systems. Resultingcomponent damage may not be covered bythe vehicle warranty.
It is very important to use predilutedcoolant approved to the correctspecification to avoid plugging the smallpassageways in the engine cooling system.See Cooling System Capacity andSpecification (page 301). Do not mixdifferent colors or types of coolant in yourvehicle. Mixing of engine coolants or usingan incorrect coolant may harm the engineor cooling system components and maynot be covered by the vehicle warranty.
Note: Coolants marketed for all makes andmodels may not be approved to Fordspecifications and may cause damage tothe cooling system. Resulting componentdamage may not be covered by the vehicleWarranty.
If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
For vehicles with overflow coolant systemswith a non-pressurized cap on the coolantrecovery system, add coolant to thecoolant recovery reservoir when the engineis cool. Add prediluted coolant to themaximum level. For all vehicles which havea coolant degas system with a pressurizedcap, or if it is necessary to remove thecoolant pressure relief cap on the radiator,follow these steps to add engine coolant:
1.Turn the engine off and let it cool.
2.Unscrew the cap slowly. Any pressureescapes as you unscrew the cap.
3.Fill the coolant reservoir slowly withprediluted engine coolant to within theminimum and maximum range on theengine coolant reservoir. If youremoved the radiator cap in anoverflow system, fill the radiator until
the coolant is visible and the radiatoris almost full. If coolant is added tobring the level within the minimum andmaximum range when the engine is notcold, the system may remain underfilled.
4.Replace the coolant reservoir cap, turnit clockwise until you feel a strongresistance.
5.Check the coolant level in the coolantreservoir the next few times you driveyour vehicle. If necessary, add enoughprediluted engine coolant to bring thecoolant level to the proper level.
Note:If prediluted coolant is not available,use the approved antifreeze concentratediluting it to 50/50 with distilled water. SeeCooling System Capacity andSpecification (page 301). Using water thathas not been deionized may contribute todeposit formation, corrosion or plugging ofthe small cooling system passageways.
If you have to add more than 1.1 qt (1 L) ofengine coolant per month, have yourvehicle checked as soon as possible.Operating an engine with a low level ofcoolant can result in engine overheatingand possible engine damage.
Note:During normal vehicle operation, thecoolant may change color from orange topink or light red. As long as the coolant isclear and uncontaminated, this color changedoes not indicate the coolant has degradednor does it require the coolant to be drained,the system to be flushed, or the coolant tobe replaced.
In case of emergency, you can add a largeamount of water without predilutedcoolant to reach a vehicle service location.On arrival do the following:
1.Drain the cooling system.
2.Chemically clean the cooling system.We recommend Motorcraft PremiumCooling System Flush.
