2017 FORD F450 SUPER DUTY radiator cap

9. Start your vehicle.
Perform Steps 4 through 8 in reverse order,making sure to engage the hinge pivotsbetween the upper and lower halves of theshroud. Keep slight pressure in the forwarddirection as you rotate the halves together.
If Your Vehicle Gets Stuck In Mudor Snow
Note:Do not rock your vehicle if the engineis not at normal operating temperature ordamage to the transmission may occur.
Note:Do not rock your vehicle for morethan a minute or damage to thetransmission and tires may occur, or theengine may overheat.
If your vehicle is stuck in mud or snow, youmay rock it out by shifting between forwardand reverse gears, stopping between shiftsin a steady pattern. Press lightly on theaccelerator in each gear.
POWER TAKE-OFF
WARNING
Use of auxiliary equipment thatexceeds the maximum PowerTake-Off (PTO) load specified in theFord Truck Body Builders Layout Book canadversely affect the performance of thepowertrain system. Refer to the BodyBuilders Layout Book for instructions aboutthe appropriate installation of additionalequipment.
Auxiliary equipment called power take-off,or PTO, is often added to the engine ortransmission to operate utility equipment.Examples include a wheel-lift for towtrucks, cranes, tools for construction or tireservice, and pumping fluids. PTOapplications draw auxiliary horsepowerfrom the powertrain, often while thevehicle is stationary. In this condition, thereis limited cooling air flow through theradiator and around the vehicle thatnormally occurs when a vehicle is moving.The aftermarket PTO system installer,having the most knowledge of the finalapplication, is responsible for determiningwhether additional chassis heat protectionor powertrain cooling is required, andalerting the user to the safe and properoperation.
Ford Super Duty Vehicles are approved foruse as a stationary (including split shaftcapability) or mobile power source, withinlimits and operating guidelines detailed inthe Ford Truck Body Builders Layout Book,found at www.fleet.ford.com/truckbbas,and through the Ford Truck Body BuildersAdvisory Service.

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.

Engine and Secondary CoolingSystem Refill Procedure
The following procedure should be usedwhen refilling the engine or secondarycooling systems after it has been drainedor become extremely low:
1. Before you remove the cap, turn theengine off and let it cool.
2. When the engine is cool, wrap a thickcloth around the cap. Slowly turn capcounterclockwise until pressure beginsto release.
3.Step back while the pressure releases.
4.When you are sure that all the pressurehas been released, use the cloth to turnit counterclockwise and remove thecap.
5. Slowly add prediluted engine coolantto the coolant reservoir until thecoolant level is within the minimumand maximum range as listed on thereservoir.
6. Reinstall the pressure relief cap.
7. Start and run the engine at 2000 rpmfor 2 minutes.
8. Shut engine off, and remove thepressure relief cap as previouslyoutlined.
9. If required, add prediluted enginecoolant to the coolant reservoir untilthe coolant level is within the minimumand maximum range as listed on thereservoir.
10.Engine cooling system: RepeatStep 5 until the coolant level hasstabilized (is no longer dropping aftereach step) and the upper radiatorhose at the radiator is warm to thetouch (indicating that the enginethermostat is open and coolant isflowing through the radiator).
11.Check the secondary cooling system.Repeat Step 5 until the coolant levelhas stabilized (is no longer droppingafter each step) and the lowerpassenger side of the secondaryradiator is warm to the touch(indicating secondary thermostat isopen and coolant is flowing throughthe entire system).
12.Reinstall the pressure relief cap. Shutthe engine off and let it cool.
13. Check the coolant level in thereservoir before you drive your vehiclethe next few times.
14. If necessary, add prediluted enginecoolant to the coolant reservoir untilthe coolant level is within theminimum and maximum range aslisted on the reservoir. After anycoolant has been added, check thecoolant concentration.
Recycled Coolant
We do not recommend the use of recycledcoolant as an approved recycling processis not yet available.
Dispose of used engine coolant in anappropriate manner. Follow yourcommunity’s regulations and standardsfor recycling and disposing of automotivefluids.
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.
