cooling FORD BRONCO 2023 User Guide

•When stopped in congested or heavytraffic during hot weather, place thetransmission in park (P) to aid engineand transmission cooling and to helpA/C performance.
•Turn off the speed control with heavyloads or in hilly terrain. The speedcontrol may turn off when you aretowing on long, steep slopes.
•Shift to a lower gear when driving downa long or steep hill. Do not continuouslyapply the brakes, as they may overheatand become less effective.
•If your transmission has Grade Assistor Tow/Haul, use this feature whentowing. This provides engine brakingand helps eliminate excessivetransmission shifting for optimum fueleconomy and transmission cooling.
•Your vehicle has AdvanceTrac with rollstability control. When towing a trailer,additional loads could cause theAdvanceTrac system to engage duringcornering maneuvers. Reduce corneringspeeds to make sure that you canmaintain control of the vehicle andtrailer if the AdvanceTrac systemengages.
•Allow more distance for stopping witha trailer attached. Anticipate stops andgradually brake.
•Avoid parking on a slope. However, ifyou must park on a slope, turn thesteering wheel to point your vehicletires away from traffic flow, set theparking brake, place the transmissionin park (P) and place wheel chocks infront and back of the trailer wheels.
Note:Chocks are not included with yourvehicle.
LAUNCHING OR RETRIEVING
A BOAT OR PERSONAL
WATERCRAFT
When backing down a ramp during boatlaunching or retrieval:
•Do not allow the static water level torise above the bottom edge of the rearbumper.
•Do not allow waves to break higherthan 6 in (15 cm) above the bottomedge of the rear bumper.
Exceeding 6 in (15 cm) could allow waterto enter vehicle components, causinginternal damage to the components andaffecting driveability, emissions andreliability.
Note:Replace the rear axle lubricantanytime the rear axle has been submergedin water.
Note:Disconnect the trailer wiringconnector before backing the trailer into thewater.
Note:Reconnect the trailer wiringconnector after removing the trailer fromthe water.

Muddy waters can reduce the coolingsystem effectiveness by depositing debrisinto the radiator.
Extra care must be taken crossing any typeof water. Do not drive into water unlessnecessary. You should only drive throughareas that are designated and approved.
High currents even in shallow water canwash the dirt out from around your tires orpush your vehicle across slippery rocks orsurfaces.
Never attempt to cross flowing water thatis deeper than your vehicles groundclearance. Even in low currents yourvehicles body surface area can be pusheddownstream and out of control.
Do not cross any body of water that is fastflowing and rising, wait for the flow rate toreduce.
Determine exit points that are downstreamof your entry point to allow for drifting.
If there are other vehicles ahead, wait untilthey’ve left the water. Unsettled water canmake a safe passage more challenging.
Know your vehicle’s abilities and be ableto recover it if something goes wrong.
Keep the doors fully closed during a watercrossing.
Vehicles used to traverse water regularlyshould be periodically inspected for signsof water ingestion in all of the vehicle'sfluids. If water is found inside your vehiclefluids, service your vehicle or see anauthorized dealer.
After driving through water and as soon asit is safe to do so, check the brakes, horn,lights, and steering wheel to make sureeverything is still in working order.
Avoid Getting High-Centered
Always keep available ground clearancein mind and pick a route that minimizes therisk of catching the underside of the vehicleon an obstacle and getting high-centered.
Freeing A Stuck Vehicle
WARNING: Do not spin the wheelsat over 34 mph (55 km/h). The tires mayfail and injure a passenger or bystander.
Recovery hooks are mounted to thevehicle's structure and are used to pull outthe vehicle from a surface or location whenstuck. Recover your vehicle using varioustowing apparatus attached to yourrecovery hook such as winch, open hook,or strap.
Note:Do not use recovery hooks torecreationally tow your vehicle. SeeRecreationally Towing Your Vehicle (page338).
If your vehicle gets stuck in mud or snow,you may rock it out by shifting betweenforward and reverse gears, stoppingbetween shifts in a steady pattern. Pressthe accelerator in each gear.
Note: Do not rock your vehicle if the engineis not at normal operating temperaturedamage to the transmission may occur.
Note:Do not rock your vehicle for morethan a minute damage to the transmissionand tires may occur or the engine mayoverheat.
If you are unable to free your vehicle callroadside assistance. See RoadsideAssistance (page 328).

In 4H, the system offers lift pedal brakingand auto hill hold functionality. See WhatIs Trail One Pedal Drive (page 223).
Note:Trail one pedal drive is only availablewhen the vehicle is in 4H or 4L.
Using Trail Turn Assist
The feature reduces the turn radius of thevehicle on off-road surfaces.
The system reduces driver effort tonegotiate difficult off-road terrain byallowing the vehicle to make a tight turnin a single maneuver that might otherwiserequire a three point turn. See Trail TurnAssist (page 227).
Note:Trail turn assist is only available whenthe vehicle is in 4H or 4L.
Note:Trail turn assist cannot activate if therear differential is locked.
What Are Rock Rails (If Equipped)
Rock rails protect the rocker and body sidefrom damage and provide a sliding surfaceto allow the vehicle to cross boulders androck ledges.
Rock rails also can act as a pivot point tosharply turn the vehicle in tight spaces withhigh walls or rocks present.
AFTER DRIVING YOUR VEHICLEOFF-ROAD
WARNING: After off-road use,before returning to the road, check thewheels and tires for damage. Off-roaduse may cause damage to your wheelsand tires that can lead to tire failure, lossof vehicle control, serious injury or death.
Driving off-road places more stress on yourvehicle than most on-road driving. Afterdriving off-road, check for damage to thewheels, chassis and underbody.
Inspect the underbody of your vehicle bychecking tires, body structure, steering,suspension, and exhaust system fordamage.
Inspect the tires for any cuts in the treador sidewall area. Also inspect the sidewallfor any bulge indicating damage to the tire.
Make sure the tires are inflated to propertire pressure as indicated on the tireplacard.
Check the radiator for mud and debris andclean as needed.
Check that the air filter is clean and dry.
Remove accumulations of plants or brush.These things could be a fire hazard or hidedamage to the fuel lines, brake hoses andpropeller shafts.
Make sure the grille and radiator are clearof any obstructions that may affectcooling.
After extended operation in mud, sand,water, or similar dirty conditions, inspectthe wipers and washers to make sure theyare working.
Note:Mud caked windows are hard to seethrough and can damage wiper blades ormotor.
Check wipers for debris or anything thatmay scratch the windshield.
If you experience unusual vibration afterdriving in mud, slush or similar conditions,check the wheels for impacted material.Impacted material can cause vibrationswhen driving and wheel imbalance.Remove the material to reduce thevibration.

ENGINE OIL CAPACITY ANDSPECIFICATION
For filling information, please refer to theCapacities and Specifications section ofyour owner's manual. See Engine OilCapacity and Specification (page 467).
CHECKING THE COOLANT
When the engine is cold, check theconcentration and level of the coolant atthe intervals listed in the scheduledmaintenance information. See ScheduledMaintenance (page 528).
Note:Make sure that the coolant level isbetween the minimum and maximum markson the coolant reservoir.
Note: Coolant expands when it is hot. Thelevel may extend beyond the MAX mark.
If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
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: Keep your hands andclothing clear of the cooling fan.

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

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 add coolantwhen the vehicle is on or the coolingsystem is hot. Failure to follow thisinstruction could result in personal injury.
WARNING: Do not add coolantfurther than the MAX mark.
WARNING: Do not put coolant inthe windshield washer reservoir. Ifsprayed on the windshield, coolant couldmake it difficult to see through thewindshield.
WARNING: Do not allow the fluidto touch your skin or eyes. If thishappens, rinse the affected areasimmediately with plenty of water andcontact your physician.
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.
Note:Automotive fluids are notinterchangeable.
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 461). 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 couldvoid the vehicle Warranty.
Note:If prediluted coolant is not available,use the approved concentrated coolantdiluting it to 50/50 with deionized ordistilled water. See Capacities andSpecifications (page 461). Using water thathas not been deionized may contribute todeposit formation, corrosion and pluggingof the small cooling system passageways.
To top up the coolant level do thefollowing:
1.Unscrew the cap slowly. Any pressureescapes as you unscrew the cap.
2.Add enough prediluted coolant toreach the correct level.
Note:We do not recommend the use ofrecycled coolant.
3.Replace the coolant reservoir cap. Turnthe cap clockwise until it contacts thehard stop.
4.Check the coolant level in the coolantreservoir the next few times you driveyour vehicle. If necessary, repeat step2.
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.
In case of emergency, you can add a largeamount of water without engine coolantin order to reach a vehicle service location.Service your vehicle as soon as possible.

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

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.
