ENGINE COOLANT CHECK
Checking the Engine Coolant
WARNING: Do not add engine coolantwhen the engine is hot. Steam and scaldingliquids released from a hot cooling systemcan burn you badly. Also, you can be burnedif you spill coolant on hot engine parts.
WARNING: Do not put engine coolantin the windshield washer fluid container. Ifsprayed on the windshield, engine coolantcould make it difficult to see through thewindshield.
WARNING: To reduce the risk ofpersonal injury, make sure the engine is coolbefore unscrewing the coolant pressure reliefcap. The cooling system is under pressure;steam and hot liquid can come out forcefullywhen the cap is loosened slightly.
WARNING: Do not add coolant furtherthan the MAX mark.
Note:Automotive fluids are notinterchangeable. Do not use engine coolantor windshield washer fluid outside of itsspecified function and vehicle location.
Note:Do not use stop leak pellets, coolingsystem sealants, or additives as they cancause damage to the engine cooling orheating systems. This damage would not becovered under your vehicle’s warranty.

Maintenance

Note:During normal vehicle operation, theengine coolant may change color fromorange to pink or light red. As long as theengine coolant is clear and uncontaminated,this color change does not indicate theengine coolant has degraded nor does itrequire the engine coolant to be drained,the system to be flushed, or the enginecoolant to be replaced.
When the engine is cold, check theconcentration and level of the engine coolantat the intervals listed in the scheduledmaintenance information. See ScheduledMaintenance (page 487).
Note:Make sure that the level is betweenthe MIN and MAX marks on the coolantreservoir.
Note:Coolant expands when it is hot. Thelevel may extend beyond the MAX mark.
Note:If the level is at the MIN mark, belowthe MIN mark, or empty, add coolantimmediately. See Adding Engine Coolantin this chapter.
The coolant concentration should bemaintained within 48% to 50%, whichequates to a freeze point between -30°F(-34°C) and -34°F (-37°C).
Note:For best results, coolant concentrationshould be tested with a refractometer suchas Robinair® Coolant and BatteryRefractometer 75240. We do notrecommend the use of hydrometers orcoolant test strips for measuring coolantconcentrations.
Adding Engine Coolant
•Do not mix different colors or types ofcoolant in your vehicle. Make sure thecorrect coolant is used. Mixing of enginecoolants may harm your engine’s coolingsystem. The use of an improper coolantmay harm engine and cooling systemcomponents and may void the warranty.Use prediluted engine coolant meetingthe Ford specification. See Capacitiesand Specifications (page 344).
•In case of emergency, a large amount ofwater without engine coolant may beadded in order to reach a vehicle servicelocation. In this instance, the coolingsystem must be drained, chemicallycleaned with Motorcraft Premium CoolingSystem Flush, and refilled with enginecoolant as soon as possible. Water alone(without engine coolant) can causeengine damage from corrosion,overheating or freezing.

Maintenance

•Do not use alcohol, methanol, brine orany engine coolants mixed with alcoholor methanol antifreeze (coolant). Alcoholand other liquids can cause enginedamage from overheating or freezing.
•Do not add extra inhibitors or additivesto the coolant. These can be harmful andcompromise the corrosion protection ofthe engine coolant.
Unscrew the cap slowly. Any pressure willescape as you unscrew the cap.
Add prediluted engine coolant meeting theFord specification. See Capacities andSpecifications (page 344).
Whenever coolant has been added, thecoolant level in the coolant reservoir shouldbe checked the next few times you drive thevehicle. If necessary, add enough predilutedengine coolant to bring the coolant level tothe proper level.
Recycled Engine Coolant
We do not recommend the use of recycledengine coolant since a Ford-approvedrecycling process is not yet available.
Used engine coolant should be disposed ofin an appropriate manner. Follow yourcommunity’s regulations and standards forrecycling and disposing of automotive fluids.
Severe Climates
If you drive in extremely cold climates:
•It may be necessary to have a Fordauthorized dealer increase the coolantconcentration above 50%.
•A coolant concentration of 60% willprovide improved freeze point protection.Engine coolant concentrations above60% will decrease the overheatprotection characteristics of the enginecoolant and may cause engine damage.
If you drive in extremely hot climates:
•It may be necessary to have a Fordauthorized dealer decrease the coolantconcentration to 40%.
•A coolant concentration of 40% willprovide improved overheat protection.Engine coolant concentrations below40% will decrease the freeze andcorrosion protection characteristics ofthe engine coolant and may causeengine damage.
Vehicles driven year-round in non-extremeclimates should use prediluted enginecoolant for optimum cooling system andengine protection.
What You Should Know About Fail-SafeCooling
If the engine coolant supply is depleted, thisfeature allows the vehicle to be driventemporarily before incremental componentdamage is incurred. The “fail-safe” distancedepends on ambient temperatures, vehicleload and terrain.

Maintenance

How Fail-Safe Cooling Works
If the engine begins to overheat, the enginecoolant temperature gauge will move to thered (hot) area and:
A high engine temperaturemessage will appear in theinformation display.
The service engine soon indicatorwill light.
If the engine reaches a presetover-temperature condition, the engine willautomatically switch to alternating cylinderoperation. Each disabled cylinder acts as anair pump and cools the engine.
When this occurs the vehicle will still operate.However:
•The engine power will be limited.
•The air conditioning system will bedisabled.
Continued operation will increase the enginetemperature and the engine will completelyshut down, causing steering and brakingeffort to increase.
Once the engine temperature cools, theengine can be re-started. Take your vehicleto an authorized dealer as soon as possibleto minimize engine damage.
When Fail-Safe Mode Is Activated
WARNING: Fail-safe mode is for useduring emergencies only. Operate yourvehicle in fail-safe mode only as long asnecessary to bring your vehicle to rest in asafe location and seek immediate repairs.When in fail-safe mode, the vehicle will havelimited power, will not be able to maintainhigh-speed operation, and may completelyshut down without warning, potentially losingengine power, power steering assist, andpower brake assist, which may increase thepossibility of a crash resulting in seriousinjury.
WARNING: Never remove the coolantreservoir cap while the engine is running orhot.
You have limited engine power when in thefail-safe mode, so drive your vehicle withcaution. Your vehicle will not be able tomaintain high-speed operation and theengine will run rough. Remember that theengine is capable of completely shuttingdown automatically to prevent enginedamage, therefore:
1. Pull off the road as soon as safelypossible and switch the engine off.
2. Arrange for your vehicle to be taken toan authorized dealer.
3.If this is not possible, wait a short periodfor the engine to cool.
4. Check the coolant level and replenish iflow.
5.Re-start the engine and take your vehicleto an authorized dealer.
Note:Driving your vehicle without repairingthe engine problem increases the chance ofengine damage. Take your vehicle to anauthorized dealer as soon as possible.

Maintenance

When a battery replacement is required, youmust use a recommended replacementbattery that matches the electricalrequirements of the vehicle.
Note:If your vehicle has a battery cover,after cleaning or replacing the battery, makesure you reinstall it.
Note:See an authorized dealer for batteryaccess, testing, or replacement.
To make sure the battery managementsystem works correctly, do not connect anelectrical device ground connection directlyto the battery negative post. This can causeinaccurate measurements of the batterycondition and potential incorrect systemoperation.
Note:If you add electrical accessories orcomponents to the vehicle, it may adverselyaffect battery performance and durability.This may also affect the performance ofother electrical systems in the vehicle.
If you see any corrosion on the battery orterminals, remove the cables from theterminals and clean with a wire brush. Youcan neutralize the acid with a solution ofbaking soda and water.
Because your vehicle’s engine iselectronically-controlled by a computer,some engine control settings are maintainedby power from the battery. Some enginecomputer settings, like the idle trim and fueltrim strategy, optimize the driveability andperformance of the engine. The clock andradio station presets are also maintained inmemory by power from the low-voltagebattery. These settings are erased when atechnician disconnects and connects thelow-voltage battery.
To restore the settings, do the following:
Note:Until you switch the ignition to the onposition, you will receive a message in yourinformation display stating that your vehicleis not in park.
1. Apply the parking brake.
2. Shift into park (P) or neutral (N).
3. Switch off all accessories.
4. Press the brake pedal and start yourvehicle.
5. Run the engine until it reaches normaloperating temperature. While the engineis warming up, complete the following:Reset the clock. See Audio Unit (page368). Reset the power windowsbounce-back feature. See PowerWindows (page 95). Reset the radiostation presets. See Audio Unit (page368).
6. Allow the engine to idle for at least oneminute.
7.Drive the vehicle at least 10 mi (16 km) tocompletely relearn the idle trim and fueltrim strategy.
Note:If you do not allow the engine torelearn the idle and fuel trim strategy, theidle quality of your vehicle may be adverselyaffected until the engine computereventually relearns the idle trim and fuel trimstrategy.
Note:Certain features may not operate ifthe battery monitor system is not reset witha scan tool following a jump start or batteryreplacement. Normal electrical accessoryoperation should resume after your vehicleis left undisturbed for 8 hours.
