2011 FORD F750 power steering

Diesel exhaust fluid (DEF), Diesel particulate filter (DPF) and Select
catalyst reduction (SCR) system
Refer to your engine operator’s manual for information regarding DEF,
DPF and SCR system service.
Air induction system
Once each year, perform a complete inspection of the air induction
system. In areas where road salt is used, the inspection consists of
disassembling the joints of each aluminum component and inspecting for
salt build-up, presence of chlorine that can cause aluminum particles to
flake off and enter the engine combustion chambers.
If evidence of corrosion is found (usually at the pipe connections), use a
wire brush to clean the inside of the pipes and inside the rubber hoses.
If the intake pipes are pitted at the joint ends, use MotorcraftSilicone
Gasket and Sealant TA-30 to seal the joints. Be certain that no excess
material is on the inside of the pipes that can be pulled into the engine.
If the service condition of the pipes, hoses or clamps is questionable,
replace the defective part(s).
Be sure that prior to reassembly all dust and debris has been cleaned out
of the pipes and couplings with a clean, damp rag.
WARNING:When performing maintenance to any turbocharged
engine with engine air inlet piping disconnected, keep loose
clothing, jewelry and long hair away from the engine air inlet piping. A
turbocharger compressor air inlet protective shield should be installed
over the turbocharger air inlet to reduce the risk of personal injury or
death.
Steering - general inspection
•Ask your service technician to examine the steering mechanism. Only
minor adjustments may be necessary.
•Check tie rod, drag link end clamp bolts and ball joints. They must be
tight.
•Check for installation and spread of cotter pins and tightness of nuts
at both ends of the tie rod and drag link.
•Check that pitman arm (steering arm at steering gear) mounting is
tight and locked. Check system for leaks or hose chafing. Repair at
once.
•Maintain proper steering gear and power steering pump lubricant
levels.

•Regularly inspect steering column joint bolts and steering linkage,
particularly for body-to-chassis clearance.
Note:Have any steering problems corrected at once by a qualified
service technician.
WARNING:Failure to maintain the steering system in proper
condition can cause reduced steering ability resulting in property
damage, personal injury or death.
Tightening steering column joint bolts
As a good maintenance practice, it is recommended that steering column
joint bolts be checked for tightness every 60,000 miles (96,000 km) or
annually, whichever occurs first. DO NOT OVERTIGHTEN.
Power steering 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.
OPENING THE HOOD
The hood and fenders are held in position by a latch located on each
fender.
WARNING:The parking brake must be fully set before opening
the hood or possible personal injury may occur.
WARNING:To reduce the risk of the possibility of personal
injury, never stand beneath the hood when it is being raised or
lowered.
WARNING:If you must leave the engine running while checking
under the hood, do not allow any loose clothing, jewelry, hair or
other items to get near moving engine components or possible personal
injury may occur.

4. Remove the dipstick from the reservoir and wipe the dipstick clean.
5. Reinstall the dipstick. Remove it again and check the fluid level.
•If the fluid temperature is at
approximately 68°-120°F
(20°-49°C) (fluid cool or warm
to the touch), check the COLD
side of the dipstick. The fluid
level should be within the FULL
range
•If the fluid level is below the ADD
line, add fluid in small amounts, continuously checking the level until
it reaches the proper level.
•If the fluid temperature is at
approximately 176°–230°F
(80°-110°C) (fluid too hot to
touch), check the HOT side of
the dipstick. The fluid level
should be within the FULL range.
•If the fluid level is below the ADD
line, add fluid in small amounts,
continuously checking the level until it reaches the proper level.
Note:The fluid level may 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.
A low fluid level may indicate a leak in the power steering system.
Inspect the power steering system and repair the leak. If necessary, see
your dealer or a qualified service technician.
To avoid damage to the power steering system,do notoperate the
vehicle with a low power steering fluid level.
Whenever the dipstick is installed, make sure it is properly seated and
tightened securely.
BRAKE FLUID
Check and refill the Full Power brake fluid reservoir using the following
procedure. Refer to theScheduled Maintenance Guidechapter for the

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, discolored fluids that also show signs of
overheating and/or foreign material contamination should be inspected
immediately by a qualified expert such as the factory-trained technicians
at your authorized servicing dealership. Your vehicle’s oils and fluids
should be changed 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 MAINTENANCE
You can do much of the maintenance your vehicle requires yourself, if
you have the time and a reasonable amount of mechanical ability. If you
prefer to have this work done professionally, your authorized dealer
stands ready to help you.
All mechanical components and attachments are important in that they
could affect the performance of vital components and systems. If
replacement becomes necessary, they must be replaced with parts having
the same part number or with equivalent parts. Torque values of the
attaching parts must be used as specified during any reassembly
procedure to ensure proper retention.
