2017 FORD F450 SUPER DUTY overheating

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 untilthe 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. SeeCapacities and Specifications (page 427).Using water that has not been deionizedmay contribute to deposit formation,corrosion or plugging of the small coolingsystem 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.
Note:In case of emergency, you can add alarge amount of water without coolant inorder to reach a vehicle service location.Water alone, without coolant, can causeengine damage from corrosion, overheatingor freezing. When you reach a servicelocation, you must have the cooling systemdrained, flushed and refilled using thecorrect specification prediluted coolant orantifreeze concentrate. See Capacities andSpecifications (page 427).
Do not use the following as a coolantsubstitute:
•Alcohol.
•Methanol.
•Brine.
•Any coolant mixed with alcohol ormethanol antifreeze.
Alcohol and other liquids can cause enginedamage from overheating or freezing.
Do not add extra inhibitors or non-specifiedadditives to the coolant. These can beharmful and compromise the corrosionprotection of the coolant.

Maintenance

Type B
Fluid levels above the safe range mayresult in transmission failure. An overfillcondition of transmission fluid may causeshift and engagement concerns, andpossible damage.
High fluid levels can be caused by anoverheating condition.
Adjusting Automatic TransmissionFluid Levels
Note:Use of a non-approved automatictransmission fluid may cause internaltransmission component damage.
Before adding any fluid, make sure thecorrect type is used. The type of fluid usedis normally indicated on:
•the dipstick handle.
•See Capacities and Specifications(page 415).
If necessary, add fluid in 8 fl oz (250 ml)increments through the filler tube until thelevel is correct.
Type A
Type B
If an overfill occurs, excess fluid should beremoved by a qualified technician.
Note:An overfill condition of transmissionfluid may cause shift and engagementconcerns, and possible damage.

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.
Owner Checks and Services
Make sure you perform the following basicmaintenance checks and inspections everymonth or at six-month intervals.
Check every month
Air filter restriction gauge.
Fuel and water separator. Drain if necessary (or if indicated by the information display).
Tires (including spare) for wear and proper pressure.
Holes and slots in the tail pipe to make sure they are functional and clear of debris.

Scheduled Maintenance

Other maintenance items1
Inspect the engine and secondary cooling system coolantconcentration (freeze-point protection), additive (corro-sion inhibitor) strength, coolant level, and hoses. Addcoolant additive if necessary.
