GENERAL MAINTENANCE INFORMATION
The general maintenance services listed in this section are required
because they are considered essential to the life and performance of
your vehicle. Refer to the “Daily Owner Checks” chart for important
maintenance items.
Ford Motor Company recommends you perform the owner maintenance
services listed in this section. These services are matters of day-to-day
care that are important to the proper operation of your vehicle. In
addition to the conditions described in owner maintenance, be alert for
any unusual noise, vibration or other indication that your vehicle may
need service and attend to it promptly.
Your vehicle is very sophisticated and built with multiple complex
performance systems. Every manufacturer develops these systems using
different specifications and performance features. That’s why it’s
important to rely upon your Ford dealership to properly diagnose and
repair your vehicle.
Use only recommended fuels, lubricants, fluids and service parts
conforming to Ford specifications. Motorcraft parts are designed and
built for best performance in your vehicle. Using these parts for
replacement is your assurance that Ford-Built quality stays in your
vehicle.
Non-Ford approved chemicals or additives are not required for factory
recommended maintenance. In fact, Ford Motor Company recommends
against the use of such additive products unless specifically
recommended by Ford for a particular application.
SCHEDULED MAINTENANCE
Ford Motor Company has recommended maintenance intervals for
various parts and component systems based upon engineering testing.
Ford Motor Company relies upon this testing to determine the most
appropriate mileage for replacement of oils and fluids to protect your
vehicle at the lowest overall cost to you and recommends against
maintenance schedules that deviate from the scheduled maintenance
information.
The maintenance or replacement of the emission control devices (or
systems) in your new Ford Motor Company vehicle (or engine) may be
performed at your expense. These services may be performed by any
automotive repair establishment or individual using automotive parts
equivalent to those with which your vehicle or engine was originally
equipped. If any parts other than Ford, Motorcraft, or Ford authorized,
2008 F-650/750(f67)
Supplement
USA(fus)
Scheduled Maintenance Guide
227
Page 229 of 273

remanufactured parts are used for maintenance replacements (or for the
service) of components effecting the emission control, the owner should
be ensured that such parts are warranted by their manufacturer to be
equivalent to genuine Ford Motor Company Parts in performance and
durability. Please consult your warranty information booklet for complete
warranty information.
Authorized dealer maintenance
Your authorized dealer specializes in knowing all about Ford Motor
Company vehicles rather than knowing a little about all makes.
There are Ford or Ford of Canada dealer service shops ready to serve
you wherever you drive in the U.S. or Canada. They stock Ford and
Motorcraft parts, and Ford Chemicals and lubricants. You can be
confident that these meet the same exacting design and quality
standards as those used to build the vehicle originally. Dealer Service
Technicians have available training in the latest product developments
and service techniques.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a normal operating characteristic of
the chemical compound and in itself does not demonstrate that a fluid
needs to be changed. Oils and fluids identified in theScheduled
Maintenance Guidechapter should be changed at the specified interval
or in conjunction with a repair. Flushing is a viable way to change fluid
for many vehicle sub-systems during scheduled maintenance and should
only be done using the same fluid required to finish the maintenance
procedure, or 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.
