3.Remove the air filter element from thehousing.
4.Install the new filter element. Becareful to put the filter seal on top ofthe tray, making sure that the seal isnot pushed down into the tray. Thiscould cause filter damage and allowunfiltered air to enter the engine if notproperly seated.
5.Install the air filter housing cover. Usespecial care to ensure that the aircleaner cover is reinstalled correctly.Verify that the tabs at the rear of theair cleaner housing cover are fullyinserted into the slots at the rear of theair cleaner housing tray.
6.Secure the air filter housing clips (x2).
ENGINE COOLANT CHECK
WARNING: Do not remove thecoolant reservoir cap when the engine ison or the cooling system is hot. Wait 10minutes for the cooling system to cooldown. Cover the coolant reservoir capwith a thick cloth to prevent thepossibility of scalding and slowly removethe cap. Failure to follow this instructioncould result in personal injury.
WARNING: Do not put coolant inthe windshield washer reservoir. Ifsprayed on the windshield, coolant couldmake it difficult to see through thewindshield.
WARNING: To reduce the risk ofpersonal injury, make sure the engine iscool before unscrewing the coolantpressure relief cap. The cooling systemis under pressure. Steam and hot liquidcan come out forcefully when you loosenthe cap slightly.
WARNING: Do not add coolantfurther than the MAX mark.

When the engine is cold, check theconcentration and level of the coolant atthe intervals listed in the scheduledmaintenance information. See ScheduledMaintenance (page 247).
Note:Make sure that the coolant level isbetween the MIN and MAX marks on thecoolant reservoir.
Note: Coolant expands when it is hot. Thelevel may extend beyond the MAX mark.
Maintain coolant concentration within48% to 50%, which equates to a freezepoint between -29°F (-34°C) and -35°F(-37°C). Coolant concentration should bechecked using a refractometer. We do notrecommend the use of hydrometers orcoolant test strips for measuring coolantconcentration.
Adding Coolant
WARNING: Do not add enginecoolant when the engine is on or thecooling system is hot. Failure to followthis instruction could result in personalinjury.
WARNING: Do not remove thecoolant reservoir cap when the engine ison or the cooling system is hot. Wait 10minutes for the cooling system to cooldown. Cover the coolant reservoir capwith a thick cloth to prevent thepossibility of scalding and slowly removethe cap. Failure to follow this instructioncould result in personal injury.
Note: Automotive fluids are notinterchangeable. Do not use coolant orwindshield washer fluid outside of itsspecified function and vehicle location.
Note: Do not use stop leak pellets, coolingsystem sealants, or non-specified additivesas they can cause damage to the enginecooling or heating systems. Resultingcomponent damage may not be covered bythe vehicle Warranty.
It is very important to use predilutedcoolant approved to the correctspecification in order to avoid plugging thesmall passageways in the engine coolingsystem. See Capacities andSpecifications (page 224). Do not mixdifferent colors or types of coolant in yourvehicle. Mixing of engine coolants or usingan incorrect coolant may harm the engineor cooling system components and maynot be covered by the vehicle Warranty.
Note:If prediluted coolant is not available,use the approved concentrated coolantdiluting it to 50/50 with distilled water. SeeCapacities and Specifications (page 224).Using water that has not been deionizedmay contribute to deposit formation,corrosion and plugging of the small coolingsystem passageways.
Note: Coolants marketed for all makes andmodels may not be approved to Fordspecifications and may cause damage tothe cooling system. Resulting componentdamage may not be covered by the vehicleWarranty.
If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
To top up the coolant level do thefollowing:
1.Unscrew the cap slowly. Any pressureescapes as you unscrew the cap.
2.Add prediluted coolant approved tothe correct specification. SeeCapacities and Specifications (page224).
3.Add enough prediluted coolant toreach the correct level.

2023 E-Series (TE4) Canada/United States of America, enUSA, Edition date: 202111, First-PrintingMaintenance

4.Replace the coolant reservoir cap. Turnthe cap clockwise until it contacts thehard stop.
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 correct level.
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, and slightlydarken. As long as the coolant is clear anduncontaminated, this color change does notindicate the coolant has degraded nor doesit require the coolant to be drained, thesystem to be flushed, or the coolant to bereplaced.
In case of emergency, you can add a largeamount of water without coolant in orderto reach a vehicle service location. In thisinstance, qualified personnel:
1.Must drain the cooling system.
2.Chemically clean the coolant system.
3.Refill with coolant that meets thecorrect specification. See Capacitiesand Specifications (page 224).
Water alone, without coolant, can causeengine damage from corrosion,overheating or freezing.
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 additives tothe coolant. These can be harmful andcompromise the corrosion protection ofthe coolant.
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.
If you drive in extremely hot climates:
•You can decrease the coolantconcentration to 40%.
•Coolant concentrations below 40%decrease the freeze and corrosionprotection characteristics of thecoolant and may cause enginedamage.
Vehicles driven year-round in non-extremeclimates should use prediluted coolant foroptimum cooling system and engineprotection.

Coolant Change
At specific mileage intervals, as listed inthe scheduled maintenance information,the coolant should be changed. Addprediluted coolant approved to the correctspecification. See Capacities andSpecifications (page 224).
Fail-Safe Cooling
Fail-safe cooling allows you to temporarilydrive your vehicle before any incrementalcomponent damage occurs. The fail-safedistance depends on ambienttemperature, vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, thecoolant temperature gauge moves towardthe red zone:
A warning lamp illuminates anda message may appear in theinformation display.
If the engine reaches a presetover-temperature condition, the engineautomatically switches to alternatingcylinder operation. Each disabled cylinderacts as an air pump and cools the engine.
When this occurs, your vehicle stilloperates, however:
•Engine power is limited.
•The air conditioning system turns off.
Continued operation increases the enginetemperature, causing the engine tocompletely shut down. Your steering andbraking effort increases in this situation.
When the engine temperature cools, youcan re-start the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.
When Fail-Safe Mode Is Activated
WARNING: Fail-safe mode is foruse during emergencies only. Operateyour vehicle in fail-safe mode only aslong as necessary to bring your vehicleto rest in a safe location and seekimmediate repairs. When in fail-safemode, your vehicle will have limitedpower, will not be able to maintainhigh-speed operation, and maycompletely shut down without warning,potentially losing engine power, powersteering assist, and power brake assist,which may increase the possibility of acrash resulting in serious injury.
WARNING: Do not remove thecoolant reservoir cap when the engine ison or the cooling system is hot. Wait 10minutes for the cooling system to cooldown. Cover the coolant reservoir capwith a thick cloth to prevent thepossibility of scalding and slowly removethe cap. Failure to follow this instructioncould result in personal injury.
Your vehicle has limited engine powerwhen in the fail-safe mode, drive yourvehicle with caution. Your vehicle does notmaintain high-speed operation and theengine may operate poorly.
Remember that the engine is capable ofautomatically shutting down to preventengine damage. In this situation:
1.Pull off the road as soon as safelypossible and switch the engine off.
2.If you are a member of a roadsideassistance program, we recommendthat you contact your roadsideassistance service provider.
3.If this is not possible, wait a shortperiod for the engine to cool.
169
2023 E-Series (TE4) Canada/United States of America, enUSA, Edition date: 202111, First-PrintingMaintenance

4.Check the coolant level. If the coolantlevel is at or below the minimum mark,add prediluted coolant immediately.
5.When the engine temperature cools,you can re-start the engine. Have yourvehicle checked as soon as possible tominimize engine damage.
Note:Driving your vehicle without repairincreases the chance of engine damage.
Engine Coolant TemperatureManagement (If Equipped)
WARNING: To reduce the risk ofcrash and injury, be prepared that thevehicle speed may reduce and thevehicle may not be able to acceleratewith full power until the coolanttemperature reduces.
If you tow a trailer with your vehicle, theengine may temporarily reach a highertemperature during severe operatingconditions, for example ascending a longor steep slope in high ambienttemperatures.
At this time, you may notice the coolanttemperature gauge moves toward the redzone and a message may appear in theinformation display.
You may notice a reduction in vehiclespeed caused by reduced engine power inorder to manage the engine coolanttemperature. Your vehicle may enter thismode if certain high-temperature andhigh-load conditions take place. Theamount of speed reduction depends onvehicle loading, grade and ambienttemperature. If this occurs, there is no needto pull off the road. You can continue todrive your vehicle.
The air conditioning may automaticallyturn on and off during severe operatingconditions to protect the engine fromoverheating. When the coolanttemperature decreases to the normaloperating temperature, the air conditioningturns on.
If the coolant temperature gauge movesfully into the red zone, or if the coolanttemperature warning or service enginesoon messages appear in your informationdisplay, do the following:
1.Pull off the road as soon as safelypossible and shift the transmission intopark (P).
2.Leave the engine running until thecoolant temperature gauge needlereturns to the normal position. If thetemperature does not drop afterseveral minutes, follow the remainingsteps.
3.Switch the engine off and wait for it tocool. Check the coolant level.
4.If the coolant level is at or below theminimum mark, immediately addprediluted coolant.
5.If the coolant level is normal, restartthe engine and continue driving.
AUTOMATIC TRANSMISSION

Checking Automatic TransmissionFluid
For scheduled intervals of the fluid checksand changes, See ScheduledMaintenance (page 247). Yourtransmission does not consume fluid.However, if the transmission is not workingproperly, for example, if the transmissionslips or shifts slowly, or if you notice somesign of fluid leakage, check the fluid levelas soon as possible.
Automatic transmission fluid expandswhen warmed. Obtain an accurate readingas follows :
1.Drive the vehicle approximately 19 mi(30 km) to reach normal operatingtemperature via the transmission fluidtemperature gauge on the instrumentcluster.
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.Put the transmission in park (P) andleave the engine running.
5.Remove the dipstick, wiping it cleanwith a clean, dry, lint free rag.
6.Install the dipstick, fully seating it in thefiller tube.
7.Remove the dipstick and inspect thefluid level. The fluid should be in thedesignated area for normal operatingtemperature or ambient temperature.
Low Fluid Level
Do not drive the vehicle if there is noindication of fluid on the dipstick and theambient temperature is above 50°F(10°C).
Correct Fluid Level
Drive the vehicle 19 mi (30 km) or until itreaches normal operating temperature.Check the fluid at the normal operatingtemperature of 196°F (91°C) to 215°F(102°C) on a level surface.

Always dispose of automotive batteries ina responsible manner. Follow your localauthorized standards for disposal. Call yourlocal authorized recycling center to findout more about recycling automotivebatteries.
Reconnecting the Battery
Because your vehicle’s engine iselectronically controlled by a computer,some control conditions are maintainedby power from the battery. When thebattery is disconnected or a new batteryis installed, the engine must relearn its idleand fuel trim strategy for optimumdriveability and performance. Flexible fuelvehicles (FFV) must also relearn theethanol content of the fuel for optimumdriveability and performance.
To begin this process.
1.Switch off all accessories and start theengine.
2.Run the engine until it reaches normaloperating temperature.
3.Allow the engine to idle for at least oneminute.
4.Turn the A/C on and allow the engineto idle for at least one minute.
5.Fully press the foot brake. Release theparking brake. Shift the gearshift leverto Drive (D) and allow the engine toidle for at least one minute.
6.Drive the vehicle for approximately10 mi (16 km) to complete therelearning process.
Note:If you do not carry out the aboveprocess, the idle quality of your vehicle maybe adversely affected until the idle trim iseventually relearned.
Flexible fuel vehicles operating on E85 mayexperience poor starts and driveabilityproblems until the fuel trim and ethanolcontent have been relearned.
When the battery is disconnected or a newbattery installed, the transmission mustlearn its adaptive strategy. As a result ofthis, the transmission may shift firmly. Thisoperation is considered normal and fullyupdates transmission operation to itsoptimum shift feel.
