2015 FORD SUPER DUTY coolant level

•the engine coolant temperature gaugemoves fully into the red (hot) area
•the coolant temperature warning lightilluminates
•the service engine soon indicatorilluminates.
WARNING
Never remove the coolant reservoircap while the engine is running or hot.
1.Pull off the road as soon as safelypossible and place the vehicle in P(Park).
2.Leave the engine running until thecoolant temperature gauge needlemoves away from the H range. Afterseveral minutes, if this does nothappen, follow the remaining steps.
3.Turn the engine off and wait for it tocool before checking the coolant level.
4.If the coolant level is normal, you mayrestart your engine and continue on.
5.If the coolant is low, add coolant,restart the engine and take your vehicleto an authorized dealer. See Addingengine coolant in this chapter for moreinformation. Refer to fail-safe coolingfor additional information.
AUTOMATIC TRANSMISSION
FLUID CHECK
Have an authorized dealer check andchange the transmission fluid and filter atthe correct service interval. SeeScheduled Maintenance (page 440).
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 (If Equipped)
For scheduled intervals of the fluid checksand changes, See ScheduledMaintenance (page 440). 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.
6.Install the dipstick making sure it is fullyseated in the filler tube.
7.Remove the dipstick and inspect thefluid level. The fluid should be in thedesignated area for normal operatingtemperature or ambient temperature.

240Super Duty (), enUSAMaintenance

Engine
•The engine oil and filter should bechanged prior to storage, as usedengine oil contain contaminates thatmay cause engine damage.
•Start the engine every 15 days. Run atfast idle until it reaches normaloperating temperature
•With your foot on the brake, shiftthrough all the gears while the engineis running.
Fuel system
•Fill the fuel tank with high-quality fueluntil the first automatic shutoff of thefuel pump nozzle.
Cooling system
•Protect against freezing temperatures.
•When removing your vehicle fromstorage, check coolant fluid level.Confirm there are no cooling systemleaks, and fluid is at the recommendedlevel.
Battery
•Check and recharge as necessary. Keepconnections clean.
•If storing your vehicle for more than 30days without recharging the battery, itmay be advisable to disconnect thebattery cables to ensure battery chargeis maintained for quick starting.
Note:If battery cables are disconnected, itwill be necessary to reset memory features.
Brakes
•Make sure brakes and parking brakeare fully released.
Tires
•Maintain recommended air pressure.
Miscellaneous
•Make sure all linkages, cables, leversand pins under your vehicle are coveredwith grease to prevent rust.
•Move vehicles at least 25 feet (8meters) every 15 days to lubricateworking parts and prevent corrosion.
Removing Vehicle From Storage
When your vehicle is ready to come out ofstorage, do the following:
•Wash your vehicle to remove any dirtor grease film build-up on windowsurfaces.
•Check windshield wipers for anydeterioration.
•Check under the hood for any foreignmaterial that may have collectedduring storage (mice/squirrel nests).
•Check the exhaust for any foreignmaterial that may have collectedduring storage.
•Check tire pressures and set tireinflation per the Tire Label.
•Check brake pedal operation. Driveyour vehicle 15 feet (4.5 meters) backand forth to remove rust build-up.
•Check fluid levels (including coolant,oil and gas) to make sure there are noleaks, and fluids are at recommendedlevels.
•If the battery was removed, clean thebattery cable ends and inspect.
Contact your authorized dealer if you haveany concerns or issues.

1Add 8 oz. (236 ml) of Additive Friction Modifier XL-3 or equivalent meeting FordSpecification EST-M2C118–A for complete refill of limited slip Ford axles. Ford designrear axles contain a synthetic lubricant that does not require changing unless you submergethe axle in water.2Ford recommends using Motorcraft (Ford) DOT 3 LV High Performance Motor VehicleBrake Fluid, Motorcraft (Ford) DOT 4 LV High Performance Motor Vehicle Brake Fluid orequivalent meeting WSS-M6C65-A1 or WSS-M6C65-A2. Use of any fluid other than therecommended fluid may cause degraded brake performance and not meet the Fordperformance standards. Keep brake fluid clean and dry. Contamination with dirt, water,petroleum products or other materials may result in brake system damage and possiblefailure.3Add the coolant type originally equipped in your vehicle.4Ford has designed your engine to use Motorcraft engine oils or equivalent oils that meetFord’s specification. It is also acceptable to use an engine oil of recommended viscositygrade that meets API SN requirements and displays the API Certification Mark for gasolineengines.5Do not use oils labeled as API SN unless the label also display the API certification mark.These oils do not meet the requirements of your vehicles engine and emissions system.6Do not use supplemental engine oil additives. They are unnecessary and could lead toengine damage not covered by your Ford warranty.7Use the correct automatic transmission fluid. Transmission fluid requirements areindicated on the dipstick blade or the dipstick handle. Check the container to verify thefluid you are adding is of the correct type. Refer to your scheduled maintenance informationto determine the correct service interval.
Note:Automatic transmissions that require MERCON LV should only use MERCON LV fluid.Use of any fluid other than the recommended fluid may cause transmission damage.8Indicates only approximate dry-fill capacity. Some applications may vary based on coolersize and if equipped with an in-tank cooler. You should set the amount of transmissionfluid and fluid level by the indication on the dipstick’s normal operating range.9Fill to the proper capacity according to dipstick Type A. For correct dipstick type, SeeAutomatic Transmission Fluid Check (page 240).9Fill to the proper capacity according to dipstick Type B. For correct dipstick type, SeeAutomatic Transmission Fluid Check (page 240).10See the Warning below:
