2002 FORD F650 oil change

Continuous operation with low
coolant temperature, below 60ÉC
(140ÉF) or high coolant temperature
100ÉC (212ÉF) can damage the
engine.
Most failures give some kind of early
warning. Look and listen for changes
in performance, sound or engine
appearance that can indicate service
or engine repair is needed. Some
changes to look and/or listen for:
²Engine misfires
²Loss of power
²Sudden changes in engine operating temperature or oil pressure
²Excessive smoke
²Fuel, oil or coolant leaks
²Vibration
²Increased oil or fuel consumption
Excessive full throttle operation below peak torque RPM will shorten
engine life to overhaul and can cause serious engine damage. Operation
of the engine below peak torque RPM can occur during gear shifting due
to difference of gear ratios.
Engine shutdown system (if equipped)
This system is designed to help prevent engine damage that could result
from operating the engine during a prolonged period of low engine oil
pressure, high engine coolant temperature or low coolant level. If any of
these conditions occur, a warning light will illuminate and a chime will
sound warning the operator that the engine will shutdown in 30 seconds.
This is to allow time for the operator to move the vehicle off the road. If
additional time is required, the engine can be restarted and run each
time for approximately 30 seconds.
Do not attempt to use this restarting feature to drive the vehicle, serious
engine damage could result.

²Front end out of alignment
²Total vehicle out of alignment (i.e. rear axle[s] out of alignment with
front axle)
²Improper adjustment in the steering gear
²Vehicle overloaded or unevenly loaded
²High crosswinds
²High crown in center of road
²Components in steering linkage loose or worn
²Wheel bearings improperly adjusted
²Excessive lash in steering shaft or universal joints
If the vehicle steers hard
Hard steering can be caused by any of the following conditions:
²Underinflated tire(s) on any wheel(s)
²Vehicle overload
²Misalignment of the front tires
²Lack of lubricant in the front spindle bearings or linkage components
²Low oil level in the power steering system
²Broken or loose power steering pump direct drive connection
²Malfunctioning relief valve in power steering gear or steering pump
²Malfunctioning power steering pump
²Restriction in power steering lines
²Improperly set turn stops
²Air entrapped in power steering system fluid
AIR SUSPENSION SYSTEM (IF EQUIPPED)
The on-highway air suspension system is designed to provide a superior
ride, outstanding driver comfort while minimizing wear on the cab, frame
and payload.
The height control valve automatically keeps the vehicle at a constant
level due to load changes and uneven road surfaces.

Engine oil and filter recommendationsÐ7.3L Power Stroke engine
To help achieve proper engine performance and durability, it is important
that you:
²Use only engine lubricating oils and oil filters of the proper quality.
²Change the engine oil and filterno laterthan the recommended
service interval. Refer to the Scheduled Maintenance Guide for the
appropriate intervals for changing the engine oil and filter.
²Change your engine oil and filter more frequently if your vehicle
operation includes extended periods of idling or low-speed operation,
driving for a long time in cold temperatures or short driving distances.
Diesel engines require specially formulated oil to resist contamination.
Proper quality oils also provide maximum efficiency of the crankcase
ventilation system which reduces air pollution.
For normal or severe service, use Motorcraft oil or an equivalent oil
conforming to Ford Specification WSS-M2C171±C or API Service
categories CH-4, CH-4/SJ or CH-4/SL. If CH-4 oil is not available, CG-4 is
acceptable.
Diesel engine oils with improved fuel economy properties (energy
conserving) are currently available. If you use an energy conserving oil,
be sure it meets Ford specification WSS-M2C171±C or API service
category designation CH-4/SJ and is of the proper viscosity grade for the
temperature range in which you expect to operate your vehicle. Some
energy conserving oils do not meet the requirements necessary for your
diesel engine.

10. Reset the air filter restriction indicator.
11. Inspect the air induction system for loose fitting, damaged or missing
components and repair as necessary.
SERVICING YOUR WHEELS AND TIRES
Wheel assembly
Your vehicle is fitted with hub
piloted wheels and two-element
swiveling lug nuts (20 & 22 mm).
Do not use taper type wheels or ball
seat wheel nuts.
²Do not paint the mating face of the hub/drum.
²Do not paint the two-element swiveling lug nuts or wheel stud.
²Do not allow an excessive thickness of paint to build between the disc
wheel mounting surfaces.
²Do not install disc wheels where the paint has not fully cured.
²At wheel changes, ensure mounting faces are clean and free of rust,
dirt and excess paint.
If fasteners are needed, use only Ford recommended replacement parts.
²To maintain the desired
torque/tension relation between
nut body and flange, it is
necessary to use clean engine oil
meeting Ford specification
WSS-M2C153-G between nut body and flange. Lubricate the nut body
and flange any time a wheel is removed.
Maintenance and Specifications

Refer to the Ford Service Manual applicable to your vehicle for proper
tightening procedures and torque specifications.
Periodically check the oil level on oil filled front bearing hubs. If
necessary, add oil through the filler plug so the oil level is between the
ADD and FULL marks indicated on the hub. Do not overfill. Overfilling
can result in oil on brake linings.
Refer to your Scheduled Maintenance Guide for fluid level checks and
change intervals for the front hubs.
Your front hubs may be filled with an optional synthetic fluid which
allows use of the extended service intervals. A green colored filler plug
identifies use of the synthetic fluid.

MINOR TROUBLESHOOTING GUIDE
Diesel engine
For troubleshooting information, refer to the diesel engine operator's
manual.
If engine won't crank
For troubleshooting information, refer to the engine operator's manual.
Maintenance and Specifications

If engine cranks but won't start
For troubleshooting information, refer to the engine operator's manual.
If engine runs hot
For troubleshooting information, refer to the engine operator's manual.
If fuses burn out
Burned-out or ªblown-outº fuses or circuit breaker tripping (if equipped)
usually indicate an electrical short circuit, although a fuse may
occasionally fail from vibration. Insert a second fuse or reset the breaker
(if equipped). If this fuse immediately burns out or the breaker (if
equipped) trips and you cannot locate the fuse, return your vehicle to
your dealer for a circuit check.
If lamp bulbs burn out
Repeated lamp burn-out usually indicates a loose connection, either at
the lamp socket, the system ground or a malfunctioning voltage
regulator. If examination does not indicate the cause of the trouble,
return your vehicle to your dealer for inspection.
If headlamps flash on and off
If headlamps flash on and off at regular intervals, the system circuit
breaker (if equipped) is operating, indicating a short circuit or overload.
Take your vehicle to your dealer for a circuit check.
