2024 FORD F650/750 air conditioning

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 inorder 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 noneed to pull off the road. You can continueto drive your vehicle.
The air conditioning may turn on and offduring severe operating conditions toprotect the engine from overheating. Whenthe coolant temperature decreases to thenormal operating temperature, the airconditioning turns 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.
AUTOMATIC TRANSMISSION
FLUID CHECK
The transmission does not consume fluid.However, check the fluid level if thetransmission is not working properly, forexample if the transmission slips, shiftsslowly or if there are signs of fluid loss.
Replace the transmission fluid and filteron your vehicle at the specified serviceinterval. See Scheduled Maintenance(page 325).
Automatic transmission fluid expandswhen warmed. To check the fluid levelconsistently and accurately, do thefollowing:
1.Drive the vehicle until it reaches normaloperating temperature. This may takeup to 20 mi (30 km). Make sure thatthe transmission fluid temperaturegauge on the instrument cluster iswithin normal operating temperature196–215°F (91–102°C) beforechecking.
2.Make sure that your vehicle is on levelground.
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.Make sure the parking brake is on. Makesure the transmission is in park (P) orneutral (N) and leave the enginerunning.
5.Open the hood. See Opening andClosing the Hood (page 223).
6.Remove the dipstick and wipe it witha clean, lint-free cloth. See UnderHood Overview (page 225).
7.Replace the dipstick and remove itagain to check the fluid level.

Note:Battery posts, terminals and relatedaccessories contain lead and leadcompounds. Wash hands after handling.
Note:Electrical or electronic accessoriesor components added to the vehicle by thedealer or the owner may adversely affectbattery performance and durability.
Your vehicle is equipped with a Motorcraftmaintenance-free battery which normallydoes not require additional water duringits life of service.
For longer, trouble-free operation, keep thetop of the battery clean and dry. Also,make certain the battery cables are alwaystightly fastened to the battery terminals.
If you see any corrosion on the battery orterminals, remove the cables from theterminals and clean with a wire brush. Youcan neutralize the acid with a solution ofbaking soda and water.
It is recommended that the negativebattery cable terminal be disconnectedfrom the battery if you plan to store yourvehicle for an extended period of time.
Because your vehicle’s engine iselectronically controlled by a computer,some control conditions are maintainedby power from the battery. When thebattery is disconnected or a new batteryis installed, the engine must relearn its idleand fuel trim strategy for optimumdriveability and performance. To begin thisprocess
1.With the vehicle at a complete stop,set the parking brake.
2.Put the gearshift in park (P) or neutral(N) and turn off all accessories.
3.Start the engine. Run the engine untilit reaches normal operatingtemperature.
4.Allow the engine to idle for at least oneminute.
5.Turn the air conditioning (if equipped)on and allow the engine to idle for atleast one minute.
6.Release the parking brake. With yourfoot on the brake pedal and with theair conditioning on, put the vehicle indrive (D) and allow the engine to idlefor at least one minute.
•If you do not allow the engine torelearn its idle trim, the idle qualityof your vehicle may be adverselyaffected until the idle trim iseventually relearned.
7.Drive the vehicle to complete therelearning process
•The vehicle may need to be driven10 mi (16 km) or more to relearn theidle and fuel trim strategy alongwith the ethanol content for flexiblefuel vehicles.
If the battery has been disconnected or anew battery has been installed, the clockand radio settings must be reset once thebattery is reconnected.
Always dispose of automotivebatteries in a responsible manner.Follow your local authorized standardsfor disposal. Call your local authorizedrecycling center to find out more aboutrecycling automotive batteries.
Battery Management System (IfEquipped)
The battery management system (BMS)monitors battery conditions and takesactions to extend battery life. If excessivebattery drain is detected, the system maytemporarily disable certain electricalfeatures to protect the battery. Thoseelectrical accessories affected include therear defrost, heated/cooled seats, climatecontrol fan, heated steering wheel, audioand navigation system. A message may beshown in the information displays to alert
