Adding Engine Oil
Note:Do not remove the filler cap when the engine is running.
Note:Do not add engine oil further than the MAX mark. Oil levels above
the MAX mark may cause engine damage.
Only use oils certified for gasoline engines by the
American Petroleum Institute (API). An oil with this
trademark symbol conforms to the current engine and
emission system protection standards and fuel
economy requirements of the International Lubricants
Specification Advisory Council (ILSAC), comprised of
U.S. and Japanese automobile manufacturers.
1. Remove the filler cap.
2. Add engine oil that meets Ford specifications. SeeCapacities and
Specificationsfor more information.
3. Replace the filler cap. Turn it until you feel a strong resistance.
ENGINE COOLANT CHECK
Checking the Engine Coolant
The concentration and level of engine coolant should be checked at the
intervals listed inScheduled Maintenance Information.
Note:Make sure that the level is at the FULL COLD level or within the
COLD FILL RANGE in the coolant reservoir.
Note:Coolant expands when it is hot. The level may extend beyond the
COLD FILL RANGE.
If the level is below the COLD FILL RANGE, add coolant immediately.
SeeAdding Engine Coolantin this chapter.
The coolant concentration should be maintained within 50%, which
equates to a freeze point between -34°F (-37°C).
Note:For best results, coolant concentration should be tested with a
refractometer such as Rotunda tool 300ROB75240 available from your
dealer. Ford does not recommend the use of hydrometers or coolant test
strips for measuring coolant concentrations.
Note:Automotive fluids are not interchangeable; do not use engine
coolant/antifreeze or windshield washer fluid outside of its specified
function and vehicle location.

EXCEPTIONS
There are several exceptions to the Normal Schedule. They are listed below:
Normal vehicle axle maintenance:Rear axles and power take-off
units with synthetic fluid and light-duty trucks equipped with
Ford-design axles are lubricated for life; do not check or change fluid
unless a leak is suspected, service is required or the assembly has been
submerged in water. During long periods of trailer towing with outside
temperatures above 70°F (21°C) and at wide-open throttle for long
periods above 45 mph (72 km/h), non-synthetic rear axle fluids should
be changed every 3000 miles (4800 kilometers) or three months,
whichever comes first. This interval can be waived if the axle is 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 (seeTechnical specificationsin theCapacities
and Specificationschapter for details).
Police, Taxi and Livery vehicle axle maintenance:Change rear axle
fluid every 100000 miles (160000 kilometers). 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 additive 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:Vehicles operating in the Middle
East, North Africa, Sub-Saharan Africa or locations with similar climates
using an American Petroleum Institute (API) Certified for Gasoline
Engines (Certification mark) oil of SM or SN quality, the normal oil
change interval is 5000 miles (8000 kilometers).
If the available API SM or SN oils are not available, then the oil change
service interval is 3000 miles (4800 kilometers).
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 require frequent
inspection and replacement of the engine air filter and cabin air filter.
