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 enginecoolant for optimum cooling system andengine protection.
Coolant Change
At specific mileage intervals, as listed inthe scheduled maintenance information,the coolant should be changed. Theinstrument cluster display may display amessage to change coolant at this time.Add prediluted coolant approved to thecorrect specification. See Capacities andSpecifications (page 291).
Engine-driven Cooling Fan (FanClutch)
Your vehicle may have an engine drivencooling fan drive (also called a fan clutch).This fan drive changes the fan speed tomatch the vehicle’s changing cooling airflow requirements. Fan speed, fan noiselevel and fuel consumption all increasebased on the driving conditions thatinclude trailer towing, hill climbing, heavyloads, high speed and high ambienttemperature, individually or in combination.
The fan drive is designed to provide theminimum fan speed (and resultingminimum fan noise and fuel consumption)required to meet the ever changing vehiclecooling air flow requirements. You can hearfan noise increasing and decreasing as theengine power requirements and vehicledriving conditions change as you drive. Thisis to be expected as being normal to theoperation of your vehicle. High levels of fannoise might also be heard when yourengine is first started, and should normallydecrease after driving for a short time.
ENGINE COOLANT CHECK -
7.3L
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 put coolant inthe windshield washer reservoir. Ifsprayed on the windshield, coolant couldmake it difficult to see through thewindshield.

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.

4.On the wall or screen you will observea flat zone of high intensity lightlocated at the top of the right handportion of the beam pattern. If the topedge of the high intensity light zone isnot at the horizontal reference line, theheadlamp will need to be adjusted.
5.Locate the vertical adjuster on eachheadlamp. Using a Phillips #2screwdriver, turn the adjuster eitherclockwise or counterclockwise in orderto adjust the vertical aim of theheadlamp.
6.Repeat Steps 3 thru 5 to adjust theother headlamp.
7.Close the hood and turn off the lamps.
Horizontal Aim Adjustment
Horizontal aim is not required for thisvehicle and is not adjustable.
WASHER FLUID CHECK
WARNING: If you operate yourvehicle in temperatures below 40°F(5°C), use washer fluid with antifreezeprotection. Failure to use washer fluidwith antifreeze protection in coldweather could result in impairedwindshield vision and increase the riskof injury or accident.
Add fluid to fill the reservoir if the level islow. Only use a washer fluid that meetsFord specifications. See Capacities andSpecifications (page 291).
State or local regulations on volatileorganic compounds may restrict the useof methanol, a common windshield washerantifreeze additive. Washer fluidscontaining non-methanol antifreezeagents should be used only if they providecold weather protection without damagingthe vehicle’s paint finish, wiper blades orwasher system.
FUEL FILTER - 7.3L
Your vehicle is equipped with a lifetimefuel filter that is integrated with the fueltank. Regular maintenance or replacementis not needed.
