ENGINE COOLANT CHECK
WARNINGS
Never remove the coolant reservoircap when the engine is running orhot.
Do not put coolant in the windshieldwasher reservoir. If sprayed on thewindshield, coolant could make itdifficult to see through the windshield.
To reduce the risk of personal injury,make sure the engine is cool beforeunscrewing the coolant pressurerelief cap. The cooling system is underpressure. Steam and hot liquid can comeout forcefully when you loosen the capslightly.
Do not add coolant further than theMAX mark.
When the engine is cold, check theconcentration and level of the coolant atthe intervals listed in the scheduledmaintenance information. See ScheduledMaintenance (page 270).

Maintenance

Note:Make sure that the coolant level isbetween the MIN and MAX marks on thecoolant reservoir.
Note: Coolant expands when it is hot. Thelevel may extend beyond the MAX mark.
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
WARNINGS
Do not add engine coolant when theengine is hot. Failure to follow thisinstruction could result in personalinjury.
Never remove the coolant reservoircap when the engine is running orhot.
Note: Automotive fluids are notinterchangeable. Do not use coolant orwindshield washer fluid outside of itsspecified function and vehicle location.
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.
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 199). 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 maynot be covered by the vehicle Warranty.
Note:If prediluted coolant is not available,use the approved concentrated coolantdiluting it to 50/50 with distilled water. SeeEngine Specifications (page 194). Usingwater that has not been deionised maycontribute to deposit formation, corrosionand plugging of the small cooling systempassageways.
Note: Coolants marketed for all makes andmodels may not be approved to Fordspecifications and may cause damage tothe cooling system. Resulting componentdamage may not be covered by the vehicleWarranty.
If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
To top up the coolant level do thefollowing:
1. Unscrew the cap slowly. Any pressureescapes as you unscrew the cap.
2. Add prediluted coolant approved tothe correct specification. SeeCapacities and Specifications (page194).
3. Add enough prediluted coolant toreach the correct level.
4.Replace the coolant reservoir cap, turnit clockwise until you feel a strongresistance.

Maintenance

5. Check the coolant level in the coolantreservoir the next few times you driveyour vehicle. If necessary, add enoughprediluted engine coolant to bring thecoolant level to the correct level.
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.
Note:During normal vehicle operation, thecoolant may change color from orange topink or light red. As long as the coolant isclear and uncontaminated, this color changedoes not indicate the coolant has degradednor does it require the coolant to be drained,the system to be flushed, or the coolant tobe replaced.
In case of emergency, you can add a largeamount of water without coolant in orderto reach a vehicle service location. In thisinstance, qualified personnel:
1. Must drain the cooling system.
2. Chemically clean the coolant system.
3. Refill with coolant that meets thecorrect specification. See Capacitiesand Specifications (page 194).
Water alone, without coolant, can causeengine damage from corrosion,overheating or freezing.
Do not use the following as a coolantsubstitute:
•Alcohol.
•Methanol.
•Brine.
•Any coolant mixed with alcohol ormethanol antifreeze.
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 coolant.
Recycled Coolant
We do not recommend the use of recycledcoolant as an approved recycling processis not yet available.
Dispose of used engine coolant in anappropriate 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 increase thecoolant concentration above 50%.
•A coolant concentration of 60%provides improved freeze pointprotection. Coolant concentrationsabove 60% decrease the overheatprotection characteristics of thecoolant and may cause enginedamage.
If you drive in extremely hot climates:
•You can decrease the coolantconcentration to 40%.
•Coolant concentrations below 40%decrease the freeze and corrosionprotection characteristics of thecoolant and may cause enginedamage.
Vehicles driven year-round in non-extremeclimates should use prediluted coolant foroptimum cooling system and engineprotection.

Maintenance

Coolant Change
At specific mileage intervals, as listed inthe scheduled maintenance information,the coolant should be changed. Addprediluted coolant approved to the correctspecification. See Capacities andSpecifications (page 194).
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
If the engine begins to overheat, thecoolant temperature gauge moves towardthe 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
WARNINGS
Fail-safe mode is for use duringemergencies only. Operate yourvehicle in fail-safe mode only as longas necessary to bring your vehicle to restin a safe location and seek immediaterepairs. When in fail-safe mode, yourvehicle will have limited power, will not beable to maintain high-speed operation, andmay completely shut down withoutwarning, potentially losing engine power,power steering assist, and power brakeassist, which may increase the possibilityof a crash resulting in serious injury.
Never remove the coolant reservoircap when the engine is running orhot.
Your vehicle has limited engine powerwhen in the fail-safe mode, drive yourvehicle with caution. Your vehicle does notmaintain high-speed operation and theengine may 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 a shortperiod 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.
