GENERAL MAINTENANCE INFORMATION
The Scheduled Maintenance Services listed in this section are required
because they are considered essential to the life and performance of
your vehicle.
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 the Owner Maintenance Checklist,
be alert for any unusual noise, vibration or other indication that your
vehicle may need service and attend to it promptly.
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.
SCHEDULED MAINTENANCE
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,
remanufactured parts are used for maintenance replacements (or for the
service) of components effecting the emission control, the owner should
be assured 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.

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.

Inspect the drive belts
Exhaust system
Inspect the entire exhaust system (including the inlet pipe(s),
muffler(s), outlet pipe(s), clamps and fasteners) for holes,
leakage, breakage, corrosive damage and separation from other
components. Adjust, service or replace with the same or the
equivalent part. (Also a noise emission control service)

Tighten the front and rear spring U-bolts to the specified torque
Driveline and rear axle system
Lubricate the U-joints and the slip yoke
Brake system
Lube the air brake foot control valve, hinge and roller
Inspect the drum brake linings through the inspection holes
Lubricate the brake camshafts (air brakes)
Lubricate the brake slack adjuster (air brakes)
Lubricate rear caliper slide rails
Inspect the disc brake pads and the piston boots (hydraulic
brakes)
Clutch system
Lubricate the clutch release cross shaft and all linkages
Check the clutch fluid
Fuel system
Drain the accumulated water or sediment from the fuel tank(s)
Steering system
Lubricate the steering shaft(s), U-joints and splines when
equipped with grease fittings
Lubricate the front axle spindle pins
Lubricate the steering linkage when equipped with grease fittings
Grease 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 water. Use only
permanent type coolant that meets Ford specifications WSS-M97B51-A1. See the engine
manufacturer’s operating guide for supplemental corrosion inhibitor specifications.

Check fuel pump pressure Insufficient full-throttle power or
backfiring
Clean radiator cap seal. Clean
and inspect the cap surface on

corrosionWhenever electrical power supply has
diminished
Tighten the wheel mounting
nuts to the specified torque.
Refer toServicing your
wheels and tiresRequired initially at 800 and 1,600 km
(500 and 1,000 miles). Perform again
at 800 and 1,600 km (500 and 1,000
mile) intervals after each tire
removal/replacement.
*a During 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.
*b Check for (free) linkage action and ensure that (return) spring
force is adequate to maintain pedal free play.
*c Adjust, repair or replace as required with the same or equivalent
parts.
