Ford E-450 (2018 year). Manual — part 37

E163741

Type B

E163742

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

E163743

Type B

E163744

Fluid levels above the safe range may
result in transmission failure. An overfill
condition of transmission fluid may cause
shift and engagement concerns, and
possible damage.

High fluid levels can be caused by an
overheating condition.

Adjusting Automatic Transmission
Fluid Levels

Note: Use of a non-approved automatic
transmission fluid may cause internal
transmission component damage.

Before adding any fluid, make sure the
correct type is used. The type of fluid used
is normally indicated on:

•

the dipstick handle.

•

See Capacities and Specifications
(page 195).

If necessary, add fluid in 8 fl oz (250 ml)
increments through the filler tube until the
level is correct.

Type A

E163745

Type B

E163746

If an overfill occurs, excess fluid should be
removed by a qualified technician.

Note: An overfill condition of transmission
fluid may cause shift and engagement
concerns, and possible damage.

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.

Automatic Transmission Fluid
Filter

E196355

Your automatic transmission is equipped
with a serviceable transmission fluid filter
located inside the transmission bottom
pan. For service intervals for the automatic
transmission fluid and transmission filter,
See Scheduled Maintenance (page 272).

For transmission filter maintenance, see
your authorized dealer.

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.

WARNINGS

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.

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 195).

POWER STEERING FLUID
CHECK

WARNINGS

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.

For E-350 and E-450 vehicles with
the Hydro-Boost Brake System, do
not press the brake pedal after the

engine has been turned off. Pressing the
brake pedal after the engine has been
turned off will give a false power steering
fluid level reading.

Only use fluid that meets Ford
specifications. See Capacities and
Specifications (page 200).

To top up the power steering fluid level do
the following.

1.

Start the engine and let it run until it
reaches normal operating temperature.

2. Make sure the fluid is within the MIN

and MAX range.

3. If the fluid level is low, add fluid to be

within the MIN and MAX range. Do not
overfill.

4. While the engine idles, turn the steering

wheel left and right several times.

5. Recheck the fluid level in the reservoir.

Note: Do not operate the vehicle with a low
power steering pump fluid level.

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 Capacities and
Specifications (page 195).

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.

CHANGING THE 12V BATTERY

WARNINGS

This vehicle may be fitted with more
than one battery, removal of cable
from only one battery does not

disconnect the vehicle electrical system.
Be sure to disconnect cables from all
batteries when disconnecting power.
Failure to do so may cause serious
personal injury or property damage.

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 proper
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/or 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.

Note: If your vehicle battery has a cover,
make sure it is reinstalled after the battery
has been cleaned or replaced.

Note: Electrical or electronic accessories
or components added to the vehicle by the
dealer or the owner may adversely affect
battery performance and durability.

Your vehicle is fitted with a Motorcraft®
maintenance-free battery which normally
does not require additional water during
its life of service.

For longer, trouble-free operation, keep the
top of the battery clean and dry. Also,
make certain the battery cables are always
tightly fastened to the battery terminals.

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.

Always dispose of automotive batteries in
a responsible manner. Follow your local
authorized standards for disposal. Call your
local authorized recycling center to find
out more about recycling automotive
batteries.

Reconnecting the Battery

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 begin this process.

1.

Switch off all accessories and start the
engine.

2. Run the engine until it reaches normal

operating temperature.

3. Allow the engine to idle for at least one

minute.
