CHECKING THE ENGINE OIL LEVEL
1.Make sure that your vehicle is on levelground.
2.Check the oil level before starting theengine, or switch the engine off afterwarm up and wait 15 minutes for theoil to drain into the oil pan.
Note:Checking the oil level too soon couldresult in an inaccurate reading.
3.Remove the dipstick and wipe it witha clean, lint-free cloth.
4.Reinstall the dipstick and make sure itis fully seated.
5.Remove the dipstick again to check theoil level.
Note: If the oil level is between themaximum and minimum marks, the oil levelis acceptable. Do not add oil.
6.If the oil level is at the minimum mark,immediately add oil.
7.Reinstall the dipstick. Make sure it isfully seated.
Note:The oil consumption of new enginesreaches its normal level after approximately3,000 mi (5,000 km).
Note:Increases in oil level can occur fromfrequent short trips that do not allow theengine to get to operating temperature, aswell as frequent idling or low speed drivingfor long periods of time.
Note:If oil levels are continuously notedabove the maximum mark, schedule a visitto your authorized dealer.
ADDING ENGINE OIL
WARNING: Do not remove the fillercap when the engine is running.
WARNING: Do not add engine oilwhen the engine is hot. Failure to followthis instruction could result in personalinjury.
Do not use supplemental engine oiladditives because they are unnecessaryand could lead to engine damage that thevehicle warranty may not cover.
1.Clean the area surrounding the engineoil filler cap before you remove it.
2.Remove the engine oil filler cap.
3.Add engine oil that meets ourspecifications. See Capacities andSpecifications (page 461).
4.Reinstall the engine oil filler cap. Turnit clockwise until you feel a strongresistance.

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.
355
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.
