ENGINE BLOCK HEATER (IF
EQUIPPED)
ENGINE BLOCK HEATERPRECAUTIONS
WARNING: Failure to follow engineblock heater instructions could result inproperty damage or serious personalinjury.
WARNING: Do not use your heaterwith ungrounded electrical systems ortwo-pronged adapters. There is a risk ofelectrical shock.
WARNING: Do not fully close thehood, or allow it to drop under its ownweight when using the engine blockheater. This could damage the powercable and may cause an electrical shortresulting in fire, injury and propertydamage.
We recommend that you do the followingfor a safe and correct operation:
•Use a 16-gauge outdoor extension cordthat is product certified byUnderwriter’s Laboratory (UL) orCanadian Standards Association(CSA). This extension cord must besuitable for use outdoors, in cold
temperatures, and be clearly markedSuitable for Use with OutdoorAppliances. Do not use an indoorextension cord outdoors. This couldresult in an electric shock or become afire hazard.
•Use as short an extension cord aspossible.
•Do not use multiple extension cords.
•Make sure that when in operation, theextension cord plug and heater cordplug connections are free and clear ofwater. This could cause an electricshock or fire.
•If the block heater cord is under thehood, do not remove the wiring fromits original location. Do not close thehood on the extension wiring.
•Make sure your vehicle is parked in aclean area, clear of combustibles.
•Make sure the heater, heater cord andextension cord are firmly connected.
•Check for heat anywhere in theelectrical hookup once the system hasbeen operating for about 30 minutes.
•Make sure the system is unplugged andproperly stowed before starting anddriving your vehicle. Make sure theprotective cover seals the prongs of theblock heater cord plug when not in use.
•Make sure the heater system ischecked for proper operation beforewinter.
HOW DOES THE ENGINE BLOCKHEATER WORK
The engine block heater warms the enginecoolant. This allows the climate controlsystem to quickly respond. The equipmentincludes a heater element installed in theengine block and a wire harness. You canconnect the system to a grounded 110 voltAC electrical source.

2023 Bronco (TG1) Canada/United States of America, enUSA, Edition date: 202208, DOMStarting and Stopping the Engine

Water alone, without engine coolant, cancause engine damage from corrosion,overheating or freezing.
Do not use the following as a coolantsubstitute, as they can cause enginedamage from overheating or freezing:
•Alcohol.
•Methanol.
•Brine.
•Any coolant mixed with alcohol ormethanol antifreeze.
Do not add extra inhibitors or additives tothe coolant. These can be harmful andcompromise the corrosion protection ofthe coolant.
Severe Climates
If you drive in extremely cold climates, youmay need to increase the coolantconcentration above 50%.
Note:A coolant concentration of 60%provides improved freeze point protection.Coolant concentrations above 60%decrease the overheat protectioncharacteristics of the coolant and couldcause engine damage.
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 531).
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.
357
2023 Bronco (TG1) Canada/United States of America, enUSA, Edition date: 202208, DOMMaintenanceE103308 E67028

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.
358
2023 Bronco (TG1) Canada/United States of America, enUSA, Edition date: 202208, DOMMaintenance

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:
1.Stop your vehicle as soon as it is safeto do so. Fully apply the parking brake,shift into park (P) or neutral (N).
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, add prediluted coolantimmediately.
5.If the coolant level is normal, restartthe engine and continue.
