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 assure proper retention.
EMISSIONS CONTROL SYSTEM
To assure the emissions control systems operate effectively, you should
have the services listed in the maintenance schedule performed at the
specified time and km/mileage intervals. You should avoid running out of
fuel or turning off the ignition while the vehicle is in motion, especially
at high speeds.
Because of high engine compartment and exhaust system
temperatures resulting from emissions equipment, do not park,
idle or operate your vehicle in dry grass or other dry ground cover
where the possibility of ground fire exists.
Do not make unauthorized modifications to the engine or vehicle.
Modifications causing increased amounts of unburned fuel to reach the
exhaust system can significantly increase the temperature of the engine
compartment and/or the exhaust system.
Avoid driving your vehicle if it does not operate properly. If the engine
diesels (more than five seconds of engine run-on after shut-off), misfires,
surges, stalls or backfires, see your dealer. Be alert for fluid leakage,
odor, smoke, loss of oil pressure, or charge indicator or over temperature
warning.
Do NOT use diesel fuel blended with waste oil in engines equipped with
a CATALYTIC CONVERTER-MUFFLER. Waste lube oil blending in fuel
will plug the CATALYTIC CONVERTER-MUFFLER, resulting in a
significant loss of engine power.

Emissions control system(s) laws
Federal law prohibits vehicle manufacturers, dealers and other persons
engaged in the business of repairing, servicing, selling, leasing or trading
motor vehicles, as well as fleet operators from knowingly removing or
rendering an emissions control device or system inoperative. Further,
modifications of the emissions control system(s) could create liability on
the part of individual owners under the laws of some states. In Canada,
modification of the emissions control system could create liability under
applicable Federal or Provincial laws.
NOISE EMISSIONS WARRANTY, PROHIBITED TAMPERING ACTS
AND MAINTENANCE
On January 1, 1978, Federal regulations became effective governing the
noise emissions on trucks over 4 535 kgs. (10 000 lbs.) GVWR. The
following statements concerning prohibited tampering acts and
maintenance and the noise warranty are found in the Warranty Guide,
and are applicable to completed trucks.
Tampering with noise control system prohibited
Federal law prohibits the following acts or the causing thereof: (1) The
removal or rendering inoperative, by any person other than for purposes
of maintenance, repair or replacement, of any device or element of
design incorporated into any new vehicle for the purpose of noise control
prior to its sale or delivery to the ultimate purchaser or while it is in use,
or (2) the use of the vehicle after such device or element of design has
been removed or rendered inoperative by any person.
Among those acts presumed to constitute tampering are the following
acts listed:
Vehicle System Acts
Acoustical Shielding Removal of noise shields, hood blanket, tunnel
liner or acoustical absorptive material.
Engine Removal or rendering inoperative the engine
speed governor so as to allow engine speed to
exceed manufacturer specifications. Removal
of engine mounted noise shield or oil pan
enclosure.

SCHEDULED MAINTENANCE SERVICES
Maintenance service adjustments must conform to specifications
contained in this manual, and those shown on the Important Engine
Information Decal. The following services are to be performed at
scheduled intervals because they are considered essential to the life and
performance of your vehicle. Ford recommends that you perform
maintenance on all designated items to achieve best vehicle operation.
Scheduled maintenance beyond 160 930 km (100 000 miles) should be
continued as before 160 930 km (100 000 miles).
SPECIAL OPERATING CONDITIONS
If your driving habitsfrequentlyinclude one or more the following
conditions:
•Short trips oflessthan 16 km (ten miles) when outside temperatures
remain below freezing.
•Operating duringhot weatherin stop-and-go“rush hour”traffic.
•Operating in severe dust conditions.
•Extensive idling, or low speed operation such as door-to-door delivery
service.
•High speed operation with a fully loaded vehicle (max. GVW).
•Snowplowing.
Perform the following:
•Change engine oil and oil filter every three months, 8 000 km (5 000
miles) or 125 hours of engine service.
•If operating in severe dust conditions, replace the air cleaner filter
more often than regular intervals as determined by the air filter
restriction indicator. Make sure that the air filter restriction indicator
is in good working order.
•Lube the manual transmission and the rear axle every 48 279 km
(30 000 miles) or 6 months, whichever comes first.
•See the Allison, Cummins and Caterpillar Operator’s Manual.

appearance, the system should be drained, flushed and refilled with the
prescribed solution of cooling system fluid and water. Use only
permanent type coolant that meets Ford specifications ESE-M97B18-C.
