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 WARNINGS
Do not handle a hot oil filter with
bare hands.
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 114).
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 423).
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.

ENGINE COOLANT CHECK -
6.2L/6.8L WARNINGS
Never remove the coolant reservoir
cap when the engine is running or
hot.
Do not put coolant in the windshield
washer reservoir. If sprayed on the
windshield, coolant could make it
difficult to see through the windshield. To reduce the risk of personal injury,
make sure the engine is cool before
unscrewing the coolant pressure
relief cap. The cooling system is under
pressure. Steam and hot liquid can come
out forcefully when you loosen the cap
slightly. Do not add coolant further than the
MAX
mark. When the engine is cold, check the
concentration and level of the coolant at
the intervals listed in the scheduled
maintenance information. See Scheduled
Maintenance
(page 581).
Note: Make sure that the coolant level is
between the
MIN and the MAX marks on
the coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the
MAX mark.
Maintain coolant concentration within
48% to 50%, which equates to a freeze
point between -30°F (-34°C) and -34°F
(-37°C). Coolant concentration should be
checked using a refractometer. We
recommend, Robinair® Coolant and
Battery Refractometer 75240 (Rotunda
tool part number: ROB75240). We do not
recommend the use of hydrometers or
coolant test strips for measuring coolant
concentration.
Note: Automotive fluids are not
interchangeable. Do not use coolant or
windshield washer fluid outside of its
specified function and vehicle location.
Note: Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the engine
cooling or heating systems. Resulting
component damage may not be covered by
the vehicle Warranty.
Adding Coolant WARNING
Never remove the coolant reservoir
cap when the engine is running or
hot.

It is very important to use prediluted
coolant meeting the correct specification
in order to avoid plugging the small
passageways in the engine cooling system.
See Capacities and Specifications
(page 428). Incorrect prediluted coolant
use can cause damage not covered by the
vehicle Warranty.
If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.
To top up the coolant level do the
following:
1. Unscrew the cap slowly. Any pressure escapes as you unscrew the cap.
2. Add prediluted coolant meeting the correct specification. See
Capacities
and Specifications (page 421).
3. Add enough prediluted coolant to reach the correct level.
4. Replace the coolant reservoir cap, turn
it clockwise until you feel a strong
resistance.
5. Check the coolant level in the coolant reservoir the next few times you drive
your vehicle.
Note: During normal vehicle operation, the
coolant may change color from orange to
pink or light red. As long as the coolant is
clear and uncontaminated, this color change
does not indicate the coolant has degraded
nor does it require the coolant to be drained,
the system to be flushed, or the coolant to
be replaced.
Do not mix different colors or types of
prediluted coolant in your vehicle. Mixing
of prediluted coolant or using an incorrect
prediluted coolant may harm the engine
or cooling system components and may
not be covered by the vehicle Warranty.
In case of emergency, you can add a large
amount of water without prediluted
coolant in order to reach a vehicle service
location. On arrival do the following: 1. Drain the cooling system.
2. Chemically clean the cooling system.
We recommend Motorcraft Premium
Cooling System Flush.
3. Refill with prediluted coolant as soon as possible.
Water alone, without prediluted coolant,
can cause engine damage from corrosion,
overheating or freezing.
Do not use the following as a coolant
substitute:
• Alcohol.
• Methanol.
• Brine.
• Any coolant mixed with alcohol or
methanol antifreeze.
Alcohol and other liquids can cause engine
damage from overheating or freezing.
Do not add extra inhibitors or additives to
the coolant. These can be harmful and
compromise the corrosion protection of
the coolant.
Recycled Coolant
We do not recommend the use of recycled
coolant as an approved recycling process
is not yet available.
Dispose of used engine coolant in an
appropriate manner. Follow your
community ’s regulations and standards
for recycling and disposing of automotive
fluids.
