2011 FORD F750 power steering fluid

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.

Every oil change
BrakesLubricate the air brake foot control valve, hinge
and roller.
Inspect the drum brake linings through the
inspection holes.
Lubricate the rear caliper slide rails.
Lubricate the brake camshafts (air brakes only).
Lubricate the brake slack adjuster (air brakes
only).
Inspect the disc brake pads and the piston boots
(hydraulic brakes only).
ClutchLubricate the clutch release cross shaft and all
linkages.
Check the clutch fluid level.
Fuel systemDrain the accumulated water or sediment from
the fuel tank(s).
Steering systemLubricate the steering shaft(s), U-joints and
splines if equipped with grease fittings.
Lubricate the front axle spindle pins.
Lubricate the steering linkage when equipped
with grease fittings.
Lubricate the power steering gear output shaft.
* Coolant protection checks should be made just prior to the onset of
freezing weather, where applicable. If coolant is dirty or rusty in
appearance, the system should be drained, flushed and refilled with the
prescribed solution of cooling system fluid and distilled water. Use only
permanent type coolant that meets specifications as listed in your
engine operator’s manual. See the engine manufacturer’s operating
guide for supplemental corrosion inhibitor specifications.
Periodic component/system checks
The following are vehicle checks that should be made periodically either
by the owner or a qualified technician. It is recommended that
deficiencies be brought to the attention of your dealer or another
qualified service outlet as soon as possible in order that advice regarding
the need for service or replacement can be obtained.

Maintenance operation Frequency/Observation
Check the transmission and
engine mountings
(2)Hard shifting or excessive vibration.
Check and adjust transmission
controls
(2)High effort to shift or noisy
transmission.
Check fuel pump pressure Insufficient full-throttle power or
backfiring.
Clean radiator cap seal. Clean
and inspect the cap surface on
the radiatorWhen the cap does not hold pressure.

Maintenance and
SpecificationschapterRequired initially at 500 and
1000 miles (800 and 1600 km).
Perform again at 500 and 1000 mile
(800 and 1600 km) intervals after
each tire removal/replacement.
Clean body/door drain holes At least twice annually.
Clean windshield wiper blades As required.
Replace windshield wiper
bladesIf wiping the blades with a clean cloth
and mild detergent and washing with
a cleaner does not restore a clean
wipe.
Lubricate body lock cylinders Noisy or difficult to operate.
Check headlamp alignment Lamp beams in wrong position when
vehicle operating loaded.
Check windshield washer fluid
level; add fluid if requiredIf washes do not spray when operated.
1During maintenance and repair, protect the fuel tube and the hose
assemblies, the power steering lines, and the brake lines from the
external heat, the acids and the abrasion that could damage the lines.
2Check for (free) linkage action and ensure that (return) spring force
is adequate to maintain pedal free play.
3Adjust, repair or replace as required with the same or equivalent
parts.
