2015 FORD F SERIES MOTORHOME AND COMMERCIAL CHASSIS overheating

Yellow area
The transmission fluid is higher thannormal operating temperature. This canbe caused by special operation conditions(i.e. snowplowing, towing or off-road use).Operating the transmission for extendedperiods of time with the gauge in theyellow area may cause internaltransmission damage. Altering the severityof the driving conditions is recommendedto lower the transmission temperature intothe normal range.
Red area
The transmission fluid is overheating. Stopthe vehicle to allow the temperature toreturn to normal range.
If the gauge is operating in the yellow orred area, stop the vehicle and verify theairflow is not restricted such as snow ordebris blocking airflow through the grill. Ifthe gauge continues to show hightemperatures, see your authorized dealer.

•Do not mix different colors or types ofcoolant in your vehicle. Make sure thecorrect coolant is used. Mixing ofengine coolants may harm the engine’scooling system. The use of an impropercoolant may harm the engine andcooling system components and mayvoid the warranty. Use predilutedengine coolant meeting the Fordspecification. See Capacities andSpecifications (page 110).
•In case of emergency, you can add alarge amount of water without enginecoolant in order to reach a vehicleservice location. In this instance, youmust have the cooling system drained,chemically cleaned with MotorcraftPremium Cooling System Flush, andrefilled with engine coolant as soon aspossible. Water alone (without enginecoolant) can cause engine damagefrom corrosion, overheating or freezing.
•Do not use alcohol, methanol, brine orany engine coolants mixed with alcoholor methanol antifreeze (coolant).Alcohol and other liquids can causeengine damage from overheating orfreezing.
•Do not add extra inhibitors or additivesto the coolant. These can be harmfuland compromise the corrosionprotection of the engine coolant.
Unscrew the cap slowly. Any pressure willescape as you unscrew the cap.
Add prediluted engine coolant meeting theFord specification. See Capacities andSpecifications (page 110).
Whenever you add coolant, check thecoolant level in the coolant reservoir thenext few times you drive the vehicle. Ifnecessary, add enough prediluted enginecoolant to bring the coolant level to theproper level.
Recycled Engine Coolant
Ford Motor Company does not recommendthe use of recycled engine coolant since aFord-approved recycling process is not yetavailable.
Used engine coolant should be disposedof in an appropriate 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 have a Fordauthorized dealer increase the coolantconcentration above 50%.
•A coolant concentration of 60% willprovide improved freeze pointprotection. Engine coolantconcentrations above 60% willdecrease the overheat protectioncharacteristics of the engine coolantand may cause engine damage
If you drive in extremely hot climates:
•It may be necessary to have a Fordauthorized dealer decrease the coolantconcentration to 40%.
•A coolant concentration of 40% willprovide improved overheat protection.Engine coolant concentrations below40% will decrease the freeze andcorrosion protection characteristics ofthe engine coolant and may causeengine damage.
Vehicles driven year-round in non-extremeclimates should use prediluted enginecoolant for optimum cooling system andengine protection.

The transmission fluid should be in thisrange if at normal operating temperature(150°F-170°F [66°C-77°C]).
The transmission fluid should be checkedat normal operating temperature150°F-170°F (66°C-77°C) on a levelsurface. The normal operating temperaturecan be reached after approximately 20miles (30 km) of driving. You can checkthe fluid without driving if the ambienttemperature is above 50°F (10°C).However, if fluid is added at this time, anoverfill condition could result when thevehicle reaches normal operatingtemperature
High fluid level
Fluid levels above the safe range mayresult in transmission failure. An overfillcondition of transmission fluid may causeshift and/or engagement concerns and/orpossible damage. High fluid levels can becaused by an overheating condition.
Adjusting automatic transmissionfluid levels
Note:Use of a non-approved automatictransmission fluid may cause internaltransmission damage. Before adding anyfluid, make sure the correct type is used. Thetype of fluid used is normally indicated onthe transmission dipstick and also in theSee Capacities and Specifications (page110).
Add fluid in ½ pint (250 ml) incrementsthrough the filler tube until the level iscorrect.
Note:If an overfill occurs, excess fluidshould be removed by an authorized dealer.An overfill condition of transmission fluidmay cause shift and/or engagementconcerns and/or possible damage.
Do not use supplemental transmissionfluid additives, treatments or cleaningagents. The use of these materials mayaffect transmission operation and resultin damage to internal transmissioncomponents.
Automatic transmission fluid filter
The TorqShift™ automatic transmissionis equipped with a serviceable transmissionfluid filter located inside the transmissionbottom pan. Refer to the scheduledmaintenance information for serviceintervals for the automatic transmissionfluid and transmission filter. Fortransmission filter maintenance, see yourauthorized dealer.
BRAKE FLUID CHECK
Fluid levels between the MIN and MAXlines are within the normal operating range;there is no need to add fluid. If the fluidlevels are outside of the normal operatingrange, the performance of the systemcould be compromised; seek service fromyour authorized dealer immediately.
