2016 FORD EXPEDITION EL engine overheat

3. Refill with engine coolant as soon aspossible.
Water alone, without engine coolant, cancause engine damage from corrosion,overheating or freezing.
Do not use the following as a coolantsubstitute:
•Alcohol.
•Methanol.
•Brine.
•Any engine coolant mixed with alcoholor methanol antifreeze or coolant.
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 engine coolant.
When adding coolant:
1. Unscrew the cap slowly. Any pressurewill escape as you unscrew the cap.
2.Add prediluted engine coolant meetingthe correct specification. SeeCapacities and Specifications (page303).
3. Check the coolant level in the coolantreservoir the next few times you driveyour vehicle.
4. If necessary, add enough predilutedengine coolant to bring the coolantlevel to the proper level.
Recycled Engine Coolant
We do not recommend the use of recycledengine coolant as an approved recyclingprocess is not yet available.
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 anauthorized dealer increase the coolantconcentration above 50%.
•A coolant concentration of 60%provides improved freeze pointprotection. Engine coolantconcentrations above 60% decreasethe overheat protection characteristicsof the engine coolant and may causeengine damage.
If you drive in extremely hot climates:
•It may be necessary to have anauthorized dealer decrease the coolantconcentration to 40%.
•A coolant concentration of 40%provides improved overheat protection.Engine coolant concentrations below40% decrease the freeze and corrosionprotection characteristics of the enginecoolant and may cause enginedamage.
Vehicles driven year-round in non-extremeclimates should use prediluted enginecoolant for optimum cooling system andengine protection.
What You Should Know About Fail-Safe Cooling
If you deplete the engine coolant supply,fail-safe cooling allows you to temporarilydrive your vehicle before you incurincremental component damage. Thefail-safe distance depends on ambienttemperatures, vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the enginecoolant temperature gauge will move tothe red (hot) area and:
the coolant temperature warninglight will illuminate

Maintenance

At this time, you may notice your enginecoolant temperature gauge needle movetoward the H and the POWER REDUCEDTO LOWER TEMP message may appearin the information display.
You may notice a reduction in vehiclespeed caused by reduced engine power.In order to manage the engine fluidtemperatures, your vehicle may enter thismode if certain high-temperature andhigh-load conditions take place. Theamount of speed reduction depends onmany factors such as vehicle loading,towing, grade and ambient temperature.If this occurs, there is no need to pull offthe road. You can continue to drive yourvehicle while this message is active.
The air conditioning may also cycle on andoff during severe operating conditions toprotect overheating of the engine. Whenthe engine coolant temperature decreasesto a normal operating temperature, the airconditioning will turn on once again.
If the engine coolant temperature gaugemoves fully into the red (hot) area, or if thecoolant temperature warning or serviceengine soon messages appear in yourinformation display:
1. Pull off the road as soon as safelypossible and shift the transmission intoP.
2. Leave the engine running until thecoolant temperature gauge needlemoves away from the red (hot) area.After several minutes, if thetemperature does not drop, follow theremaining steps.
3.Switch the engine off and wait for it tocool before checking the coolant level.
4. If the coolant level is normal, restartyour engine and continue.
5. If the coolant is low, add coolant, andrestart the engine. See Adding EngineCoolant or How Fail-Safe CoolingWorks in this chapter for moreinformation.
AUTOMATIC TRANSMISSION
FLUID CHECK
If required, have an authorized dealer checkand change the transmission fluid at thecorrect service interval. See ScheduledMaintenance (page 372).
The automatic transmission does not havea transmission fluid dipstick.
Refer to your scheduled maintenanceinformation for scheduled intervals for fluidchecks and changes. Your transmissiondoes not consume fluid. However, if thetransmission slips, shifts slowly or if younotice a sign of leaking fluid, contact anauthorized dealer.
Do not use supplemental transmissionfluid additives, treatments or cleaningagents. The use of these materials mayaffect transmission operation and resultin damage to internal transmissioncomponents.

Maintenance

When the oil change message appears inthe information display, it is time for an oilchange. Make sure you perform the oilchange within two weeks or 500 miles(800 kilometers) of the messageappearing. Make sure you reset theIntelligent Oil-Life Monitor after each oilchange. See Oil Change Indicator Reset(page 246).
If your information display resetsprematurely or becomes inoperative, youshould perform the oil change interval atsix months or 5000 miles (8000kilometers) from your last oil change.Never exceed one year or 10000 miles(16000 kilometers) between oil changeintervals.
Your vehicle is very sophisticated and builtwith multiple, complex, performancesystems. Every manufacturer developsthese systems using differentspecifications and performance features.That is why it is important to rely upon yourdealership to properly diagnose and repairyour vehicle.
Ford Motor Company has recommendedmaintenance intervals for various partsand component systems based uponengineering testing. Ford Motor Companyrelies upon this testing to determine themost appropriate mileage for replacementof oils and fluids to protect your vehicle atthe lowest overall cost to you andrecommends against maintenanceschedules that deviate from the scheduledmaintenance information.
We strongly recommend the use of onlygenuine Ford, Motorcraft orFord-authorized re-manufacturedreplacement parts engineered for yourvehicle.
Additives and Chemicals
This owner's manual and the FordWorkshop Manual list the recommendedadditives and chemicals for your vehicle.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. However, a qualified expert, suchas the factory-trained technicians at yourdealership, should inspect discolored fluidsthat also show signs of overheating orforeign material contaminationimmediately.
Make sure to change your 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 a Ford-approved flushingchemical.
Owner Checks and Services
Make sure you perform the following basicmaintenance checks and inspections everymonth or at six-month intervals.
