To check the engine oil level consistently
and accurately, do the following:
1. Make sure that your vehicle is on level ground.
2. Run engine until it reaches normal operating temperature.
3. Make sure the parking brake is on. Make
sure the transmission is in park (P) or
neutral (N).
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.

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.
CHANGING THE ENGINE OIL
AND OIL FILTER WARNING: Do not add engine oil
when the engine is hot. Failure to follow
this instruction could result in personal
injury.
If your vehicle has 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 109).
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 431).
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
Engine Specifications
(page 429).
5. For diesel engines, you need to reset the Intelligent Oil Life Monitor™. See
Information Displays
(page 109).
Engine Lubrication for Severe
Service Operation
The following conditions define severe
operation:
• Frequent or extended idling such as
over 10 minutes per hour of normal
driving.
• Low-speed operation or stationary use.
• If the vehicle is operated in sustained,
ambient temperatures below
-9°F
(-23°C) or above 100°F (38°C).
• Frequent low-speed operation, or
consistent heavy traffic less than
25 mph (40 km/h)
.
• Operating in severe dust conditions.
• Operating the vehicle off road.
• Towing a trailer over
1,000 mi
(1,600 km).
• Sustained, high-speed driving at the
gross vehicle weight rating.
• Use of fuels with sulfur content other
than ultra-low sulfur diesel (ULSD).
• Use of high-sulfur diesel fuel.
Only use engine oil that meets our
specifications.
OIL CHANGE INDICATOR
RESET
Use the information display controls on
the steering wheel to reset the oil change
indicator.

Super Duty (TFE), enUSA, Edition date: 201909, Third-Printing- Maintenance

If you drive in extremely hot climates:
•
It may be necessary to decrease the
coolant concentration to 40%.
• A coolant concentration of 40%
provides improved overheat
protection. Coolant concentrations
below 40% decrease the freeze and
corrosion protection characteristics of
the coolant and may cause engine
damage.
Vehicles driven year-round in non-extreme
climates should use prediluted coolant for
optimum cooling system and engine
protection.
Fail-Safe Cooling
Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs. The fail-safe
distance depends on ambient
temperature, vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the
coolant temperature gauge moves toward
the red zone: A warning lamp illuminates and
a message may appear in the
information display.
If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating
cylinder operation. Each disabled cylinder
acts as an air pump and cools the engine.
When this occurs, your vehicle still
operates, however:
• Engine power is limited.
• The air conditioning system turns off. Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.
When the engine temperature cools, you
can re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage.
When Fail-Safe Mode Is Activated
WARNING: Fail-safe mode is for
use during emergencies only. Operate
your vehicle in fail-safe mode only as
long as necessary to bring your vehicle
to rest in a safe location and seek
immediate repairs. When in fail-safe
mode, your vehicle will have limited
power, will not be able to maintain
high-speed operation, and may
completely shut down without warning,
potentially losing engine power, power
steering assist, and power brake assist,
which may increase the possibility of a
crash resulting in serious injury. WARNING:
Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap
with a thick cloth to prevent the
possibility of scalding and slowly remove
the cap. Failure to follow this instruction
could result in personal injury.
Your vehicle has limited engine power
when in the fail-safe mode, drive your
vehicle with caution. Your vehicle does not
maintain high-speed operation and the
engine may operate poorly.
Remember that the engine is capable of
automatically shutting down to prevent
engine damage. In this situation:
1. Pull off the road as soon as safely possible and switch the engine off.
