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 481).
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.

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
WARNINGS
Fail-safe mode is for use duringemergencies 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.
Never remove the coolant reservoircap while the engine is running or hot.
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.
