2013 FORD F750 power steering

The Power Park Brake is controlled by the park brake dash-mounted,
yellow knob-type switch. The switch has three positions: apply (out),
neutral (central), and release (in). The switch is spring-loaded to return
to the neutral (central) position after being pushed or pulled.
There is no visual indication at the knob that the park brake is
applied or released; check the instrument cluster. If the light is
illuminated, the parking brake is applied.
Applying the Parking Brake
Pull the yellow, dash-mounted parking brake knob. The parking brake
light illuminates indicating that the parking brake has been successfully
set.
Note:If the light blinks and a warning chime sounds when the control
knob is pulled, the parking brake is not functioning properly. Seek
immediate service from your dealer. SeeParking brake warning
systemin this section.
Releasing the Parking Brake
WARNING:Hold the brake pedal down while moving the
gearshift lever from position to position. If the brake pedal is not
held down, the vehicle may move unexpectedly resulting in property
damage, personal injury or death.
Note:Read and understand the following steps and perform them
whenever you prepare to drive the vehicle.
Note:The parking brake does not disengage unless sufficient system air
pressure is available.
If your vehicle is equipped with a dash-mounted push button (Allison
3000 Series) or steering column-mounted (Allison 2200 and 2500) gear
selector:
1. Press and hold the service brake pedal while the engine is running.

Hot Weather
•Use a permanent-type engine coolant to protect the engine against
damage from overheating.
•Fill the fuel tank at the end of daily operation to prevent
condensation in the fuel system.
•Keep external surfaces of the engine, radiator, charge air cooler, A/C
condenser and accessories clean to avoid dirt build-up.
•Above normal coolant temperatures could be experienced while
driving in a transmission gear ratio which lugs the engine. To correct
this problem, engine speed should be increased by downshifting into
the next lower gear.
STEERING
Your vehicle is equipped with power steering. Power steering uses energy
from the engine to decrease the driver’s effort in steering the vehicle.
To help prevent damage to the power steering pump:
•Never hold the steering wheel to the extreme right or the extreme
left for more than a few seconds when the engine is running.
•Do not operate the vehicle with the power steering pump fluid level
below the ADD mark on the MAX. COLD side of the power steering
reservoir dipstick.
•Some noise is normal during operation. If the noise is excessive,
check for low power steering pump fluid level before seeking service
by your authorized dealer.
•Heavy or uneven steering efforts may be caused by low power
steering pump fluid level. Check for low power steering pump fluid
level before seeking service by your authorized dealer.
•Do not fill the power steering pump reservoir above the FULL mark
on the MAX. HOT side of the power steering reservoir dipstick, as
this may result in leaks from the reservoir.
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, check for:
•underinflated tire(s) on any wheel(s)
•uneven vehicle loading
•high crown in center of road
•high crosswinds
•wheels out of alignment
•loose or worn suspension components.

The upper portion of the switch must be pressed before operating with a
trailer or operating in the bobtail mode.
Suspension Conversions
WARNING:When operating a loaded vehicle, the driver must
keep all adjustable axles on the ground at all times, supporting
their share of the vehicle’s load. Failure to do so can overload other
axles, tires, wheels, springs, steering components, brakes and frames,
resulting in early component failure, loss of vehicle control, possible
property damage and personal injury.
It is not recommended, or approved, that suspension conversions be
performed. However, it is understood that, on occasion, aftermarket
add-on suspensions are installed by others on the truck chassis which
allow operator control for weight transfer from other axles (i.e., air lift
axles).
UPFITTER CONTROLS (IF EQUIPPED)
The upfitter option package
provides four switches, mounted in
the center of the instrument panel.
These switches are always on
whether the engine is running or
not. Make sure you put the switches
in the off position to avoid draining
the battery when the vehicle is not
being used. It is recommended that the engine remain running to
maintain battery charge when using the upfitter switches for extended
duration or higher current draws. (This is even more important for
vehicles with a diesel engine since the glow plugs are also draining
battery power when the ignition key is in the on position.)
Each switch provides 10 amps of electrical battery power for a variety of
personal or commercial uses.
There is also a relay box located on the passenger side end of the
instrument panel. See your authorized dealer for service.
Switch access location is in a connector located in the engine
compartment. More detailed information can be found at
https://www.fleet.ford.com/truck/bbas/.

Steering System
WARNING:Failure to maintain the steering system in proper
condition can cause reduced steering ability resulting in property
damage, personal injury or death.
Note:Have any steering problems immediately corrected by a qualified
service technician.
Ask your service technician to examine the steering mechanism. Only
minor adjustments may be necessary. Regular inspections should include:
•checking the tie rod, drag link end clamp bolts and ball joints for
proper tightness.
•checking for installation and spread of cotter pins and tightness of
nuts at both ends of the tie rod and drag link.
•checking that the pitman arm (steering arm at steering gear)
mounting is tight and locked. Check system for leaks or hose chafing.
Repair immediately, if necessary.
•maintaining proper steering gear and power steering pump lubricant
levels.
•checking steering column joint bolts and steering linkage, particularly
for body-to-chassis clearance.
Steering Column Joint Bolts
As a good maintenance practice, it is recommended that steering column
joint bolts be checked for tightness every 60000 miles (96000 kilometers)
or annually, whichever occurs first. DO NOT OVERTIGHTEN.
Hydraulic System
Whenever the power steering’s hydraulic system has been drained and
refilled for any reason, air must be bled from the system before returning
the vehicle to service. Failure to properly bleed the hydraulic system can
result in degradation of power system performance.
Consult your dealer who is aware of the proper procedures for filling and
bleeding the system.

POWER STEERING FLUID CHECK
Note:To avoid damage to the power steering system, do not operate the
vehicle with a low power steering fluid level.
Note:If adding fluid is necessary, use only the appropriate fluid. See the
Capacities and Specificationschapter. A low fluid level may indicate a
leak in the power steering system. Inspect the power steering system
and repair the leak or see your dealer or a qualified technician for
service. See theScheduled Maintenancechapter for the recommended
service intervals.
Check the fluid level when it is at ambient temperature, 20°F–80°F
(-7°C–25°C):
1. Set the parking brake, then start the engine.
2. Shift into positionNorP(if equipped) (automatic transmission) or
first gear (manual transmission) and turn the engine off.
3. Open the hood.
4. Clean the top of the power steering fluid reservoir.
5. Remove the dipstick from the reservoir and wipe the dipstick clean.
6. Reinstall the dipstick. Remove it again and check the fluid level.
Check the MAX. COLD side of the
dipstick if the fluid is cool or warm to
the touch (approximately 68°F-120°F
[20°C-49°C]). The fluid level should
be within the FULL range. If
necessary, add fluid in small amounts,
continuously checking the level, until
it reaches the proper level.
Check the MAX. HOT side of the
dipstick if the fluid is too hot to
touch (approximately 176°F–230°F
[80°C-110°C]). The fluid level
should be within the FULL range.
If necessary, add fluid in small
amounts, continuously checking the
level, until it reaches the proper
level.
Whenever the dipstick is installed, make sure it is properly seated and
tightened securely.
The fluid level can also be checked by looking at the see-through plastic
reservoir. Make sure that the fluid is within the minimum and maximum
fluid range as marked on the reservoir.

Additives and Chemicals
This owner’s manual and the Ford Workshop Manual list the
recommended additives and chemicals for your vehicle. We do not
recommend using chemicals or additives not approved by us as part of
your vehicle’s normal maintenance. Please consult your warranty
information.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a normal operating characteristic
and, by itself, does not necessarily indicate a concern or that the fluid
needs to be changed. However, a qualified expert, such as the
factory-trained technicians at your dealership, should inspect discolored
fluids that also show signs of overheating or foreign material
contamination immediately.
Make sure to change your vehicle’s oils and fluids at the specified
intervals or in conjunction with a repair. Flushing is a viable way to
change fluid for many vehicle sub-systems during scheduled
maintenance. It is critical that systems are flushed only with new fluid
that is the same as that required to fill and operate the system or using a
Ford-approved flushing chemical.
Owner Checks and Services
Certain basic maintenance checks and inspections should be performed
monthly or at six month intervals.
