2018 FORD F250 SUPER DUTY maintenance

To avoid fluid contamination, the reservoir
cap must remain in place and fully tight,
unless you are adding fluid.
Only use fluid that meets Ford
specifications. See Capacities and
Specifications (page 421).
POWER STEERING FLUID
CHECK
Check the power steering fluid. See
Scheduled Maintenance
(page 581). If
adding fluid is necessary, use only
MERCON LV ATF
Note: This procedure is for vehicles with
gasoline engines. Vehicles with diesel
engines are similar. See Under Hood
Overview in your diesel supplement.
Check the fluid level when it is at ambient
temperature. 1. Check the fluid level in the reservoir. It
should be between the MIN and MAX
range. Do not add fluid if the level is
within this range.
2. If the fluid level is low, add fluid to bring
the fluid level up to between the MIN
and MAX range.
3. Switch the engine on.
4. While the engine idles, turn the steering
wheel left and right several times.
5. Switch the engine off.
6. Recheck the fluid level in the reservoir. Do not add fluid if the level is between
the MIN and MAX range.
7. If the fluid is low, add fluid in small amounts, continuously checking the
level until it is between the MIN and
MAX range. For proper fluid type, See
Capacities and Specifications (page
421). Be sure to put the cap back on the
reservoir.
WASHER FLUID CHECK WARNING
If you operate your vehicle in
temperatures below 40°F (5°C), use
washer fluid with antifreeze
protection. Failure to use washer fluid with
antifreeze protection in cold weather could
result in impaired windshield vision and
increase the risk of injury or accident. Add fluid to fill the reservoir if the level is
low. Only use a washer fluid that meets
Ford specifications. See

State or local regulations on volatile
organic compounds may restrict the use
of methanol, a common windshield washer
antifreeze additive. Washer fluids
containing non-methanol antifreeze
agents should be used only if they provide
cold weather protection without damaging
the vehicle
’s paint finish, wiper blades or
washer system.
DRAINING THE FUEL FILTER
WATER TRAP - 6.7L DIESEL WARNING
Do not dispose of fuel in the
household refuse or the public
sewage system. Use an authorized
waste disposal facility. Your vehicle has a diesel fuel conditioner
module. The module is mounted between
the outboard side of the fuel tank and the
frame rail.
Note:
The module is at the front of the fuel
tank or at the front of the aft-axle fuel tank
on some models. You should drain water from the
module assembly whenever the
warning light illuminates or a
message appears in the information
display advising you to drain the water
separator. This occurs when approximately
6.76 fl oz (200 ml) of water accumulates
in the module. If you allow the water level
to exceed this level, the water may pass
through to the engine and may cause fuel
injection equipment damage.

CHANGING THE 12V BATTERY
WARNINGS
Batteries normally produce explosive
gases which can cause personal
injury. Therefore, do not allow
flames, sparks or lighted substances to
come near the battery. When working near
the battery, always shield your face and
protect your eyes. Always provide correct
ventilation. When lifting a plastic-cased battery,
excessive pressure on the end walls
could cause acid to flow through the
vent caps, resulting in personal injury and
damage to the vehicle or battery. Lift the
battery with a battery carrier or with your
hands on opposite corners. Keep batteries out of reach of
children. Batteries contain sulfuric
acid. Avoid contact with skin, eyes or
clothing. Shield your eyes when working
near the battery to protect against possible
splashing of acid solution. In case of acid
contact with skin or eyes, flush
immediately with water for a minimum of
15 minutes and get prompt medical
attention. If acid is swallowed, call a
physician immediately. Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash hands after
handling. This vehicle may have more than one
battery. Removing the battery cables
from only one battery does not
disconnect your vehicle electrical system.
Make sure you disconnect the battery
cables from all batteries when
disconnecting power. Failure to do so may
cause serious personal injury or property
damage. Your vehicle is fitted with a Motorcraft
maintenance-free battery which normally
does not require additional water.
When a battery replacement is required,
you must use a recommended
replacement battery that matches the
electrical requirements of the vehicle.
Note:
After cleaning or replacing the
battery, make sure you reinstall the battery
cover or shield.
Note: If you add electrical accessories or
components to the vehicle, it may adversely
affect the low voltage battery performance
and durability. This may also affect the
performance of other electrical systems in
the vehicle.
For longer, trouble-free operation, keep the
top of the battery clean and dry.
If you see any corrosion on the battery or
terminals, remove the cables from the
terminals and clean with a wire brush. You
can neutralize the acid with a solution of
baking soda and water.
Because your vehicle ’s engine is
electronically controlled by a computer,
some control conditions are maintained
by power from the battery. When the
battery is disconnected or a new battery
is installed, the engine must relearn its idle
and fuel trim strategy for optimum
driveability and performance. Flexible fuel
vehicles (FFV) must also relearn the
ethanol content of the fuel for optimum
driveability and performance.
To restore the settings, do the following:
1. Apply the parking brake.
2. Shift into park (P) or neutral (N).
3. Switch off all accessories.
4. Press the brake pedal and start your vehicle.
354
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 201709, First Printing Maintenance

5. Run the engine until it reaches normal
operating temperature. While the
engine is warming up, complete the
following: Reset the clock. Reset the
power windows bounce-back feature.
See Windows and Mirrors (page 98).
Reset the radio station presets. See
Audio System (page 446).
6. Allow the engine to idle for at least one
minute.
7. Drive the vehicle at least 10 mi (16 km)
to completely relearn the idle trim and
fuel trim strategy.
Note: If you do not allow the engine to
relearn the idle and fuel trim strategy, the
idle quality of your vehicle may be adversely
affected until the engine computer
eventually relearns the idle trim and fuel
trim strategy.
Note: For flexible fuel vehicles, if you are
operating on E85, you may experience poor
starts or an inability to start the engine and
driveability problems until the fuel trim and
ethanol content have been relearned.
Make sure that you dispose of old batteries
in an environmentally friendly way. Seek
advice from your local authority about
recycling old batteries.
If storing your vehicle for more than 30
days without recharging the battery, we
recommend that you disconnect the
battery cables to maintain battery charge
for quick starting.
Battery Management System
(If
Equipped)
The battery management system monitors
battery conditions and takes actions to
extend battery life. If excessive battery
drain is detected, the system temporarily
disables some electrical systems to
protect the battery. Systems included are:
•
Heated rear window.
• Heated seats.
• Climate control.
• Heated steering wheel.
• Audio unit.
• Navigation system.
A message may appear in the information
displays to alert you that battery
protection actions are active. These
messages are only for notification that an
action is taking place, and not intended to
indicate an electrical problem or that the
battery requires replacement.
After battery replacement, or in some
cases after charging the battery with an
external charger, the battery management
system requires eight hours of vehicle sleep
time to relearn the battery state of charge.
During this time your vehicle must remain
fully locked with the ignition switched off.
Note: Prior to relearning the battery state
of charge, the battery management system
may temporarily disable some electrical
systems.
Electrical Accessory Installation
To make sure the battery management
system works correctly, do not connect an
electrical device ground connection
directly to the battery negative post. This
can cause inaccurate measurements of
the battery condition and potential
incorrect system operation.
Note: If you add electrical accessories or
components to the vehicle, it may adversely
affect battery performance and durability.
This may also affect the performance of
other electrical systems in the vehicle.
