Coolant Change
At specific mileage intervals, as listed in
the scheduled maintenance information,
the coolant should be changed. The
information display may display a message
to change coolant at this time. Add
prediluted coolant approved to the correct
specification. See Capacities and
Specifications (page 420).
Engine-driven Cooling Fan (Fan
Clutch)
Your vehicle may have an engine driven
cooling fan drive (also called a fan clutch).
This fan drive changes the fan speed to
match the vehicle ’s changing cooling air
flow requirements. Fan speed, fan noise
level and fuel consumption all will increase
based on the driving conditions that
include trailer towing, hill climbing, heavy
loads, high speed and high ambient
temperature, individually or in combination.
The fan drive is designed to provide the
minimum fan speed (and resulting
minimum fan noise and fuel consumption)
required to meet the ever changing vehicle
cooling air flow requirements. You will hear
the amount of fan noise increasing and
decreasing as the engine power
requirements and vehicle driving conditions
change as you drive. This is to be expected
as being normal to the operation of your
vehicle. High levels of fan noise might also
be heard when your engine is first started,
and should normally decrease after driving
for a short time.
AUTOMATIC TRANSMISSION
FLUID CHECK
Have an authorized dealer check and
change the transmission fluid and filter at
the correct service interval. See
Scheduled Maintenance
(page 581). Do not use supplemental transmission
fluid additives, treatments or cleaning
agents. The use of these materials may
affect transmission operation and result
in damage to internal transmission
components.
Checking Automatic Transmission
Fluid
For scheduled intervals of the fluid checks
and changes, See
Scheduled
Maintenance (page 581). Your
transmission does not consume fluid.
However, the fluid level should be checked
if the transmission is not working properly,
i.e., if the transmission slips or shifts slowly
or if you notice some sign of fluid leakage.
Automatic transmission fluid expands
when warmed. To obtain an accurate fluid
check, drive the vehicle until it is at normal
operating temperature (approximately
19 mi (30 km)
). Verify that the
transmission fluid temperature gauge,
located on the instrument cluster, is within
normal range.
1. Drive the vehicle
19 mi (30 km)until it
reaches normal operating temperature.
2. Park the vehicle on a level surface and
engage the parking brake.
3. With the engine running, parking brake
engaged and your foot on the brake
pedal, move the gearshift lever through
all of the gear ranges. Allow sufficient
time for each gear to engage.
4. Latch the gearshift lever in P and leave
the engine running.
5. Remove the dipstick, wiping it clean with a clean, dry lint free rag. If
necessary, refer to the Under Hood
Overview in this chapter for the
location of the dipstick.

6.
Install the dipstick making sure it is fully
seated in the filler tube.
7. Remove the dipstick and inspect the fluid level. The fluid should be in the
designated area for normal operating
temperature or ambient temperature.
Low Fluid Level
Type A Type B
Do not drive the vehicle if there is no
indication of fluid on the dipstick and the
ambient temperature is above 50°F
(10°C).
Correct Fluid Level
Type A Type B
For vehicles equipped with 5-speed
transmissions, check the fluid at the
normal operating temperature of
151°F
(66°C) to 170°F (77°C) on a level surface.
For vehicles equipped with 6-speed
transmissions, check the fluid at the
normal operating temperature of
196°F
(91°C) to 215°F (102°C) on a level surface.
The normal operating temperature can be
reached after approximately
19 mi
(30 km).
High Fluid Level
Type A

Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 201709, Second Printing MaintenanceE163739 E163740 E163741 E163742

Do not use supplemental transmission
fluid additives, treatments or cleaning
agents. The use of these materials may
affect transmission operation and result
in damage to internal transmission
components.
TRANSFER CASE FLUID
CHECK (If Equipped)
1. Clean the filler plug.
2. Remove the filler plug and inspect the
fluid level.
3. Add only enough fluid through the filler
opening so that the fluid level is at the
bottom of the opening.
Only use fluid that meets Ford
specifications. See
Capacities and
Specifications (page 420). BRAKE FLUID CHECK WARNINGS
Do not use any fluid other than the
recommended brake fluid as this will
reduce brake efficiency. Use of
incorrect fluid could result in the loss of
vehicle control, serious personal injury or
death. Only use brake fluid from a sealed
container. Contamination with dirt,
water, petroleum products or other
materials may result in brake system
damage or failure. Failure to adhere to this
warning could result in the loss of vehicle
control, serious personal injury or death. Do not allow the fluid to touch your
skin or eyes. If this happens, rinse the
affected areas immediately with
plenty of water and contact your physician. A fluid level between the
MAX and
MIN lines is within the normal
operating range and there is no need
to add fluid. A fluid level not in the normal
operating range could compromise the
performance of the system. Have your
vehicle checked immediately. 349
