heating FORD EXPEDITION 2023 User Guide

If you drive in extremely hot climates, youmay need to decrease the coolantconcentration to 40%.
Note:A coolant concentration of 40%provides improved overheat protection.Coolant concentrations below 40%decrease the overheat and corrosionprotection characteristics of the coolant andcould cause engine damage.
Coolant Change
WARNING: Do not dispose ofcoolant in the household refuse or thepublic sewage system. Use an authorizedwaste disposal facility.
Change the coolant at specific mileageintervals. Refer to the scheduledmaintenance information. See NormalScheduled Maintenance (page 542).
Note:Dispose of used coolant in theappropriate manner.
Follow your community's regulations andstandards for recycling and disposing ofautomotive fluids.
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
WARNING: If you continue to driveyour vehicle when the engine isoverheating, the engine could stopwithout warning. Failure to follow thisinstruction could result in the loss ofcontrol of your vehicle.
If the engine begins to overheat,the coolant temperature gaugemoves toward the 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 could 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 for a shortperiod of time for the engine to cool.
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:If you continue to drive your vehiclein fail-safe mode without repairing it, youwill damage your engine.
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 grade 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 noneed to stop your vehicle. You cancontinue to drive.
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:

You can also drive your vehicle in such away that dilutes and increases the level ofoil by frequent short trips that do not allowthe engine to get to operating temperature,extended idling and low speed driving forlong periods of time.
It is important to rely upon your dealershipto properly diagnose and repair yourvehicle.
We strongly recommend only using ourgenuine or our authorized re-manufacturedreplacement parts engineered for yourvehicle.
Additives and Chemicals
We do not recommend using chemicals oradditives not approved by us as part ofyour vehicle’s normal maintenance. Pleaseconsult your warranty information.
Oils, Fluids and Flushing
In many cases, fluid discoloration is anormal operating characteristic and, byitself, does not necessarily indicate aconcern or that the fluid needs to bechanged. Have discolored fluids that alsoshow signs of overheating or foreignmaterial contamination checkedimmediately.
Make sure to change the vehicle’s oils andfluids at the specified intervals or inconjunction with a repair. Flushing is aviable way to change fluid for many vehiclesub-systems during scheduledmaintenance. It is critical that systems areflushed only with new fluid that is the sameas that required to fill and operate thesystem or using our approved flushingchemical.
Owner Checks and Services
Make sure you perform the following basicmaintenance checks and inspections.
Check Every Month
The air filter restriction gauge.1
The engine oil level.
Function of all interior and the exterior lights.
The tires including the spare for wear and proper pressure.
The windshield washer fluid level.
The fuel and water separator. Drain if necessary or if indicated by the instrument cluster
display.1
The holes and slots in the tail pipe to make sure they are functional and clear of debris.1
1 Diesel vehicles only.
