VEHICLE INSPECTION
INFORMATION
To make sure your vehicle is ready to
operate, conduct a pre-trip inspection at
the beginning of each work period. Follow
the steps listed in this section to verify a
proper vehicle inspection procedure.
WARNING: Exercise great caution
when working on a vehicle equipped with
an automatic fan clutch. The fan starts
in motion only after the engine coolant
reaches a predetermined temperature
or the refrigerant pressure (if equipped
with air conditioning) reaches a
predetermined setting. The fan starts at
this point with no advance warning.
Never reach near, or permit objects to
protrude into, the fan blade radius while
the engine is running as this could result
in vehicle damage, personal injury or
death. WARNING:
Do not operate the
vehicle if any suspension conditions
listed in the following charts are evident.
Loss of steering or suspension could
result in property damage, personal injury
or death. WARNING:
If a wheel must be
changed, obtain expert tire service help.
Mounting and un-mounting of tires
should only be performed by a qualified
technician using necessary safety
procedures and equipment, otherwise
the result could be property damage,
personal injury or death.
Note: Always make sure you apply the
parking brake before starting the engine. Engine compartment (with engine off)
Use the dipstick to verify the oil level is in the proper operating
range. See
Engine Oil Dipstick (page 217).

Look through the plastic reservoir and verify the coolant level
is within the proper operating range. Do not remove the
pressure cap until the coolant has cooled. See
Engine
Coolant Check (page 226).
Engine coolant
Verify that the fluid level is in the proper operating range. See
Power Steering Fluid Check
(page 238).

ENGINE OIL CHECK - 7.3L
To check the engine oil level consistently
and accurately, do the following:
1. Make sure the parking brake is on. Make
sure the transmission is in park (P) or
neutral (N). 2. Run the engine until it reaches normal
operating temperature.
3. Make sure that your vehicle is on level ground.
4. Switch the engine off and wait 15 minutes for the oil to drain into the oil
pan. Checking the engine oil level too
soon after you switch the engine off
may result in an inaccurate reading.
5. Open the hood. See Maintenance
(page 212).
6. Remove the dipstick and wipe it with a clean, lint-free cloth. See
Maintenance
(page 212).
7. Replace the dipstick and remove it again to check the oil level. See
Maintenance
(page 212).
8. Make sure that the oil level is between
the maximum and minimum marks. If
the oil level is at the minimum mark,
add oil immediately. See
Capacities
and Specifications (page 281).
9. If the oil level is correct, replace the dipstick and make sure it is fully seated.
Note: Do not remove the dipstick when the
engine is running.
Note: If the oil level is between the
maximum and minimum marks, the oil level
is acceptable. Do not add oil.
Note: The oil consumption of new engines
reaches its normal level after approximately
3,000 mi (5,000 km)
.
Adding Engine Oil WARNING: Do not remove the filler
cap when the engine is running.
Do not use supplemental engine oil
additives because they are unnecessary
and could lead to engine damage that may
not be covered by the vehicle Warranty.

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 Committee (ILSAC).
To top up the engine oil level do the
following:
1. Clean the area surrounding the engine
oil filler cap before you remove it.
2. Remove the engine oil filler cap.
3. Add engine oil that meets the correct specification.
4. Recheck the oil level.
5. If the oil level is correct, replace the dipstick and make sure it is fully seated.
6. Replace the engine oil filler cap. Turn it clockwise until you feel a strong
resistance.
Note: Do not add oil further than the
maximum mark. Oil levels above the
maximum mark may cause engine damage.
Note: Make sure you install the oil filler cap
correctly.
Note: Soak up any spillage with an
absorbent cloth immediately. ENGINE OIL CHECK - 6.7L

Adding Engine Oil
WARNING: Do not remove the filler
cap when the engine is running.
Do not use supplemental engine oil
additives because they are unnecessary
and could lead to engine damage that may
not be covered by the vehicle Warranty.
To top up the engine oil level do the
following:
1. Clean the area surrounding the engine oil filler cap before you remove it.
2. Remove the engine oil filler cap. See Under Hood Overview (page 215).
Turn it counterclockwise and remove
it.
3. Add engine oil of the proper viscosity and grade that meets Ford
specifications. See
Capacities and
Specifications (page 288). You may
have to use a funnel to pour the engine
oil into the opening.
4. Recheck the oil level.
5. If the oil level is correct, replace the dipstick and make sure it is fully seated.
6. Replace the engine oil filler cap. Turn it clockwise until you feel a strong
resistance.
Note: Do not add oil further than the
maximum mark. Oil levels above the
maximum mark may cause engine damage.
Note: Make sure you install the oil filler cap
correctly.
Note: Soak up any spillage with an
absorbent cloth immediately. Engine lubrication for severe
service operation
The following conditions define severe
operation for which engine operation with
SAE 5W-40 oil which meets Ford
specification, WSS-M2C171-F1, is
recommended. Oil and oil filter change
intervals will be determined by the
Intelligent Oil Life Monitor™ as noted
previously.
CHANGING THE ENGINE OIL
AND OIL FILTER
WARNING: Do not handle a hot oil
filter with bare hands. WARNING:
Continuous contact
with used motor oil has caused cancer
in laboratory mice. Protect your skin by
washing with soap and water.
If your vehicle is equipped with a diesel
engine, an Intelligent Oil Life Monitor™
calculates the proper oil change service
interval. When the information display
indicates: OIL CHANGE REQUIRED, change
the engine oil and oil filter. See
Information Displays
(page 70).
The engine oil filter protects your engine
by filtering harmful, abrasive or sludge
particles and particles significantly smaller
than most available will-fit filters. See
Motorcraft Parts
(page 283).
1. Unscrew the oil filter and oil pan drain plug and wait for the oil to drain.
2. Replace the filter.
3. Reinstall the oil pan drain plug.
4. Refill the engine with new oil. See Capacities and Specifications (page
288
).
