2017 FORD F250 SUPER DUTY coolant temperature

To help prolong engine life, werecommended you allow the engine to idlefor three to five minutes, especially afterany of the following:
•Continuous engine speed.
•High ambient temperature.
•High GVW or GCW operation, forexample heavy loads or trailers.
This allows the turbo charged engine tocool down.
ENGINE IDLE SHUTDOWN (If
Equipped)
Your vehicle may be equipped with anengine idle shutdown system. This systemautomatically shuts down your enginewhen it has been idling in P (Park) or N(Neutral) for five minutes (parking brakeset) or 15 minutes (parking brake not set).When the engine idle shutdown processhas started:
•A chime sounds and the informationdisplay will show ENGINE TURNS OFFIN 30 (seconds) and start countingdown
•You can restart the five or 15-minutetimer by changing the position of theaccelerator pedal, brake pedal or thepark brake within the final 30 seconds
•When the timer reaches zero, theengine shuts down and this messagewill appear in your information displayENGINE TURNED OFF
•One minute after the engine has shutdown, the electrical system simulateskey off, even though the ignition is stillin the on position, initiating normalaccessory delay period
•You must move the ignition to the offposition to reset the system beforerestarting your vehicle.
The engine idle shutdown idle timer doesnot start if:
•The engine is operating in powertake-off mode.
•The engine coolant temperature isbelow 60°F (16°C).
•The exhaust emission control device isregenerating.
ENGINE BLOCK HEATER (If
Equipped)
WARNINGS
Failure to follow engine block heaterinstructions could result in propertydamage or serious personal injury.
Do not use your heater withungrounded electrical systems ortwo-pronged adapters. There is a riskof electrical shock.
Note:The heater is most effective whenoutdoor temperatures are below 0°F(-18°C).
The heater acts as a starting aid bywarming the engine coolant. This allowsthe climate control system to respondquickly. The equipment includes a heaterelement (installed in the engine block) anda wire harness. You can connect thesystem to a grounded 120-volt ACelectrical source.

Starting and Stopping the Engine

Switching Between E85 andGasoline
We do not recommend repeatedlyalternating between E85 and gasoline. Ifyou switch from using E85 to gasoline, orfrom gasoline to E85, add as much fuel aspossible, at least half a tank. Drive yourvehicle immediately for a minimum of 5 mi(8 km) to allow it to adapt to the changein ethanol concentration. If you use E85exclusively, we recommend that you fillthe fuel tank with regular unleadedgasoline at each scheduled oil change.
FUEL QUALITY - DIESEL
Fuel Requirements - Choosing TheRight Fuel: Vehicles OperatedWhere Ultra Low Sulfur Diesel FuelIs Required (UnitedStates/Canada/Puerto Rico/U.S.Virgin Islands And Other Locales)
You should use Ultra-Low Sulfur Dieselfuel (also known as ULSD) designated asnumber 1-D or 2-D with a maximum of15-ppm sulfur in your diesel vehicle. Youmay operate your vehicle on diesel fuelscontaining up to 20% biodiesel, alsoknown as B20. These fuels should meetthe ASTM D975 diesel or the ASTM D7467B6-B20 biodiesel industry specifications.Outside of North America, use fuelsmeeting EN590 or equivalent local marketstandard.
Note:The vehicle Warranty does not coverdamage caused by using an improper typeof fuel or fuel additive.
Note:Do not blend used engine oil withdiesel fuel under any circumstances.Blending used oil with the fuel willsignificantly increase your vehicle’s exhaustemissions and reduce engine life due toincreased internal wear.
Using low sulfur diesel fuel(16-500 ppm) or high sulfurdiesel fuel (greater than 500ppm) in your diesel engine will causecertain emission components tomalfunction which may also cause theservice engine soon light to illuminateindicating an emissions-related concern.
Diesel fuel is adjusted seasonally for coldtemperature. For best results attemperatures below 19°F (-7°C), it isrecommended to use a diesel fuel whichhas been seasonally adjusted for theambient conditions.
Fuel Requirements - Choosing TheRight Fuel: Vehicles OperatedWhere Ultra Low Sulfur Diesel FuelIs Not Required
For the engine to operate reliably onlow-sulfur or high-sulfur diesel fuel, theengine must be a factory built high-sulfurengine (available as a dealer order optionfor select markets) or an ultra low sulfurdiesel fuel configured engine that has beenretrofitted for high-sulfur diesel fuel usingFord Motor Company dealer service parts.Failure to use retrofit components otherthan those available through yourauthorized dealer will result in coolantsystem damage, engine overheating,selective catalyst reduction system ordiesel particulate filter damage andpossible base engine damage.
Use only a diesel engine configured for usewith high sulfur diesel fuel in markets withdiesel fuel that has sulfur content greaterthan 15 ppm. Using low sulfur diesel fuel(16–500 ppm) or high sulfur diesel fuel(greater than 500 ppm) in a diesel enginedesigned to use only Ultra Low SulfurDiesel fuel may result in damage to engineemission control devices and theaftertreatment system, potentiallyrendering the vehicle inoperable.

Maintenance

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:
•It may be necessary to decrease thecoolant concentration to 40%.
•A coolant concentration of 40%provides improved overheat protection.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 coolant foroptimum cooling system and engineprotection.
Fail-Safe Cooling
Fail-safe cooling allows you to temporarilydrive your vehicle before any incrementalcomponent damage occurs. The fail-safedistance depends on ambienttemperature, vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, thecoolant temperature gauge moves towardthe red zone:
A warning lamp illuminates anda message may appear in theinformation display.
If the engine reaches a presetover-temperature condition, the engineautomatically switches to alternatingcylinder operation. Each disabled cylinderacts as an air pump and cools the engine.
When this occurs, your vehicle stilloperates, however:
•Engine power is limited.
•The air conditioning system turns off.
Continued operation increases the enginetemperature, causing the engine tocompletely shut down. Your steering andbraking effort increases in this situation.
When the engine temperature cools, youcan re-start the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.
When Fail-Safe Mode Is Activated
WARNINGS
Fail-safe mode is for use duringemergencies only. Operate yourvehicle in fail-safe mode only as longas necessary to bring your vehicle to restin a safe location and seek immediaterepairs. When in fail-safe mode, yourvehicle will have limited power, will not beable to maintain high-speed operation, andmay completely shut down withoutwarning, potentially losing engine power,power steering assist, and power brakeassist, which may increase the possibilityof a crash resulting in serious injury.
Never remove the coolant reservoircap while the engine is running or hot.
Your vehicle has limited engine powerwhen in the fail-safe mode, drive yourvehicle with caution. Your vehicle does notmaintain high-speed operation and theengine may operate poorly.
Remember that the engine is capable ofautomatically shutting down to preventengine damage. In this situation:

Maintenance

1. Pull off the road as soon as safelypossible and switch the engine off.
2. If you are a member of a roadsideassistance program, we recommendthat you contact your roadsideassistance service provider.
3. If this is not possible, wait a shortperiod for the engine to cool.
4. Check the coolant level. If the coolantlevel is at or below the minimum mark,add prediluted coolant immediately.
5. When the engine temperature cools,you can re-start the engine. Have yourvehicle checked as soon as possible tominimize engine damage.
Note:Driving your vehicle without repairincreases the chance of engine damage.
Engine Coolant TemperatureManagement (If Equipped)
WARNING
To reduce the risk of crash and injury,be prepared that the vehicle speedmay reduce and the vehicle may notbe able to accelerate with full power untilthe coolant temperature reduces.
If you tow a trailer with your vehicle, theengine may temporarily reach higher atemperature during severe operatingconditions, for example ascending a longor steep grade in high ambienttemperatures.
At this time, you may notice the coolanttemperature gauge moves toward the redzone and a message may appear in theinformation display.
You may notice a reduction in vehiclespeed caused by reduced engine power.In order to manage the engine coolanttemperature. Your vehicle may enter thismode if certain high-temperature andhigh-load conditions take place. Theamount of speed reduction depends onvehicle loading, grade and ambienttemperature. If this occurs, there is no needto pull off the road. You can continue todrive your vehicle.
The air conditioning may automaticallyturn on and off during severe operatingconditions to protect the engine fromoverheating. When the coolanttemperature decreases to the normaloperating temperature, the air conditioningturns on.
If the coolant temperature gauge movesfully into the red zone, or if the coolanttemperature warning or service enginesoon messages appear in your informationdisplay, do the following:
1. Pull off the road as soon as safelypossible and shift the transmission intopark (P).
2. Leave the engine running until thecoolant temperature gauge needlereturns to the normal position. Afterseveral minutes, if the temperaturedoes not drop, follow the remainingsteps.
3.Switch the engine off and wait for it tocool. Check the coolant level.
4. If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
5. If the coolant level is normal, restartthe engine and continue.

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.
