Note:Make sure the tire valve stem clears the brake caliper when
installing the tire and rim assembly on disc-brake equipped axles. The
use of a tire manufacturer’s stem forming tool is the only acceptable
method of obtaining clearance when necessary.
Proper Torque
It is important to tighten and maintain wheel and rim mounting nuts to
the proper torque. Loose nuts or over-tightened nuts can lead to
premature wear and possible failure of the wheel or mounting hardware.
Changing Wheel Types
WARNING:Use only the same type and style wheels and
mounting hardware to replace original parts. Failure to do so may
result in an assembly that looks fine, but does not fit together properly.
This could possibly cause wheel or fastener failures which could result
in property damage, personal injury or death.
Note:Do not attempt to mix stud-piloted wheels or fasteners with
hub-piloted wheels or fasteners.
Note:Do not change from aluminum wheels to steel wheels or
vice-versa without changing the mounting hardware required or, with
flange nut mounting systems, changing the hub and stud assembly.
Consult your dealer or wheel or rim distributor before attempting any
wheel or fastener changes.

Note:Do not use lubrication on dry threads. Where excessive corrosion
exists, a light coat of lubricant on the first three threads of the stud bolt
is permitted. Keep lubricant away from:
•Hex nut and rim clamp contact surfaces.
•Cap nut ball face and ball seat on the disc wheel.
•Flange nut washer surface and flat on the disc wheel.

Additives and Chemicals
This owner’s manual and the Ford Workshop Manual list the
recommended additives and chemicals for your vehicle. We do not
recommend using chemicals or additives not approved by us as part of
your vehicle’s normal maintenance. Please consult your warranty
information.
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, a qualified expert, such as the
factory-trained technicians at your dealership, should inspect discolored
fluids that also show signs of overheating or foreign material
contamination immediately.
Make sure to change your vehicle’s oils and fluids 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 Checks and Services
Certain basic maintenance checks and inspections should be performed
monthly or at six month intervals.
Daily Owner Checks
EngineAir filter restriction gauge.
Engine oil level.
Engine coolant level.
Brake SystemAir brake reservoir automatic drain valve
operation.

Observation Maintenance Operation
Cleaning the wiper blades with a
clean cloth and mild detergent and
washing with a cleaner does not
restore a clean wipe.Replace wiper blades.
Noisy or difficult to operate. Lubricate body lock cylinders.
Headlamp beams in wrong position
when vehicle operating loaded.Check headlamp alignment.
Windshield washers do not spray

level. Add fluid if required.
1During maintenance and repair, protect the fuel tube and the hose
assemblies, power steering lines, and brake lines from external heat,
acids and abrasions that could damage them.
2Check for (free) linkage action and make sure that (return) spring force
is adequate to maintain pedal free play.
3Adjust, repair or replace, as required, with the same or equivalent parts.
Emissions Control System
WARNING: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.
To make sure the emissions control systems operate effectively, you
should have the services listed in the maintenance schedule performed at
the specified time and mileage intervals. You should avoid running out of
fuel or turning off the ignition while the vehicle is in motion, especially
at high speeds.
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 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.

Emissions Information Label
Emissions information appears on the Important Engine Information
decal located on or near the engine.
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.
Maintenance intervals are provided for three types of general vehicle
environments: On-Highway, City and Severe Service. In all applications,
the actual interval is determined by monitoring miles (kilometers) and
time and when the engine is due for an oil change. When the engine oil
change is required prior to the truck lubrication interval, it is
recommended that the lubrication be performed at the same time in
order to reduce your vehicle’s time out of service.
Air Brake Adjustment
WARNING:Failure to maintain proper air brake adjustment can
result in reduction or loss of braking ability.
Air brake inspection and adjustment or repairs should be performed by a
qualified service technician in accordance with the instructions in the
service manual.
