What you should know about fail-safe cooling
If the engine coolant supply is depleted, this feature allows the vehicle to
be driven temporarily before incremental component damage is incurred.
The “fail-safe” distance depends on ambient temperatures, vehicle load
and terrain.
How fail-safe cooling works
If the engine begins to overheat:
•The engine coolant temperature gauge
will move to the red (hot)
area.
•The engine coolant temperature indicator will illuminate.
•The service engine soon indicator light will illuminate.
If the engine reaches a preset over-temperature condition, the engine
will automatically switch to alternating cylinder operation. Each disabled
cylinder acts as an air 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 be disabled.
Continued operation will increase the engine temperature:
•The engine will completely shut down.
•Steering and braking effort will increase.
Once the engine temperature cools, the engine can be re-started. Take
your vehicle to an authorized dealer as soon as possible to minimize
engine damage.
When fail-safe mode is activated
You have limited engine power when in the fail-safe mode, so drive the
vehicle with caution. The vehicle will not be able to maintain high speed
operation and the engine will run rough. Remember that the engine is
capable of completely shutting down automatically to prevent engine
damage, therefore:
1. Pull off the road as soon as safely possible and turn off the engine.
2. Arrange for the vehicle to be taken to an authorized dealer.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and replenish if low.

EXCEPTIONS
In addition, there are several exceptions to the Normal Schedule. They
are listed below:
Normal vehicle axle maintenance
❑Rear axles and power take-off (PTO) units containing synthetic fluid and light duty trucks equipped with Ford-design axles
are lubricated for life. These fluids are not to be checked or changed unless a leak is suspected, service is required or the
axle assembly has been submerged in water. The axle and PTO fluids should be changed anytime the axle and PTO have
been submerged in water. During extended trailer tow operation above 70°F (21°C) ambient and wide open throttle for
extended periods above 45 mph (72 km/h), non-synthetic rear axle fluids should be changed every 3,000 miles
(4,800 km) or three months, whichever occurs first. The 3,000 mile (4,800 km) fluid change interval may be waived if
the axle was filled with 75W140 synthetic gear fluid meeting Ford specification WSL-M2C192-A, part number F1TZ-19580-B
or equivalent. Add friction modifier XL-3 (EST-M2C118-A) or equivalent for complete refill of Traction-Lok rear axles (refer to
Maintenance product specifications and capacitiesin theMaintenance and Specificationschapter for details). The axle fluid
should be changed anytime an axle has been submerged in water.
Police/Taxi/Livery vehicle axle maintenance
❑Change rear axle fluid every 100,000 miles (160,000 km). Rear axle fluid change may be waived if the axle was filled
with 75W140 synthetic gear fluid meeting Ford specification WSL-M2C192-A, part number FITZ-19580-B or equivalent. Add
four ounces (118 mL) of friction modifier XL-3 (EST-M2C118-A) or equivalent for complete refill of Traction-Lok rear axles.
The axle fluid should be changed anytime the axle has been submerged in water.
California fuel filter replacement
❑If the vehicle is registered in California, the California Air Resources Board has determined that the failure to perform this
maintenance item will not nullify the emission warranty or limit recall liability prior to the completion of the vehicle’s useful
life. Ford Motor Company, however, urges you to have all recommended maintenance services performed at the specified
intervals and to record all vehicle service.
Hot climate oil change intervals
❑If operating conditions are normal and you drive your vehicle under typical, everyday conditionsandyou are using an API
performance category oil of SL or later (for example SM, etc.) then you can follow the 7,500 mile (12,000 km) normal
service oil change intervals schedule. Vehicles operating in the Middle East, North Africa, Sub-Saharan Africa or locations with
similar climates must follow the oil change interval of 3,000 mile (4,800 km) if the owner is using oils defined by the
American Petroleum Institute (API) performance category of API SK or earlier (for example SJ, etc.).
Engine air filter & cabin air filter replacement
❑Engine air filter and cabin air filter life is dependent on exposure to dusty and dirty conditions. Vehicles operated in these
conditions will require frequent inspection and replacement of the engine air filter and cabin air filter.
