CHANGING A FUSE
Fuses
WARNING
Always replace a fuse with one thathas the specified amperage rating.Using a fuse with a higher amperagerating can cause severe wire damage andcould start a fire.
If electrical components in the vehicle arenot working, a fuse may have blown. Blownfuses are identified by a broken wire withinthe fuse. Check the appropriate fusesbefore replacing any electricalcomponents.

ENGINE OIL CHECK
Note:Check the level before starting theengine.
Note:Make sure that the level is betweenthe MIN and the MAX marks.
1.Make sure that your vehicle is on levelground.
2.Turn the engine off and wait 10 minutesfor the oil to drain into the oil pan.
3.Remove the dipstick and wipe it witha clean, lint-free cloth. Replace thedipstick and remove it again to checkthe oil level.
If the level is at the MIN mark, add oilimmediately.
Adding Engine Oil
Note:Do not remove the filler cap whenthe engine is running.
Note:Do not add oil further than the MAXmark. Oil levels above the MAX mark maycause engine damage.
Only use oils certified for gasoline enginesby the American Petroleum Institute (API).An oil with this trademark symbolconforms to the current engine andemission system protection standards andfuel economy requirements of theInternational Lubricants SpecificationAdvisory Council (ILSAC), comprised ofU.S. and Japanese automobilemanufacturers.
1.Remove the filler cap.
2.Add engine oil that meets the Fordspecifications. See Capacities andSpecifications (page 111).
3.Replace the filler cap. Turn it until youfeel a strong resistance.
Resetting the Oil Life MonitoringSystem
Note:Reset the oil life monitoring only afteran oil change.
1.Turn the ignition key to the ON position.Do not start the engine. For vehicleswith push-button start, press and holdthe start button for two secondswithout pressing the brake pedal. Donot attempt to start the engine.
2.Press both the accelerator and brakepedals at the same time.
3.Keep both pedals fully pressed.

5.After 25 seconds, the Service: Oil resetcomplete message will be displayed.
6.Release the accelerator and brakepedals, then rotate the key to the offposition.
Note:The Service: Oil reset completemessage will no longer be displayed.
ENGINE COOLANT CHECK
WARNINGS
Do not add engine coolant when theengine is hot. Steam and scaldingliquids released from a hot coolingsystem can burn you badly. Also, spillingcoolant on hot engine parts can burn you.
Do not put engine coolant in thewindshield washer fluid container. Ifsprayed on the windshield, enginecoolant could make it difficult to seethrough the windshield.
To reduce the risk of personal injury,make sure the engine is cool beforeunscrewing the coolant pressurerelief cap. The cooling system is underpressure; steam and hot liquid can comeout forcefully when you loosen the capslightly.
Do not add coolant further than theMAX mark.
When the engine is cold, check theconcentration and level of the enginecoolant at the intervals listed in thescheduled maintenance information. SeeScheduled Maintenance (page 121).
Note:Make sure that the level is betweenthe MIN and MAX marks on the coolantreservoir.
Note:Coolant expands when it is hot. Thelevel may extend beyond the MAX mark
Note:If the level is at the MIN mark, belowthe MIN mark, or empty, add coolantimmediately. See Adding Engine Coolantin this chapter.
The coolant concentration should bemaintained within 48% to 50%, whichequates to a freeze point between -30°F(-34°C) and -34°F (-37°C).
Note:For best results, coolantconcentration should be tested with arefractometer such as Robinair Coolant andBattery Refractometer 75240. We do notrecommend the use of hydrometers orcoolant test strips for measuring coolantconcentrations.
Note:Automotive fluids are notinterchangeable. Do not use engine coolant,antifreeze or windshield washer fluid outsideof its specified function and vehicle location.
Adding Engine Coolant
Note:Do not use stop leak pellets, coolingsystem sealants, or additives as they cancause damage to the engine cooling orheating systems. Your vehicle’s warrantydoes not cover this damage.
76Motorhome (TY3) , enUSAMaintenance

•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 111).
•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 111).
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.
