ELECTRICAL SYSTEM INSPECTIONS
Periodically inspect electrical connectors on the outside of the cab, on
the engine and frame for corrosion and tightness. Exposed terminals
such as the fuel sender, cranking motor, alternator and feed-through
studs should be cleaned and re-coated with a lubricant sealing grease
such as Motorcraft Silicone Brake Caliper Grease and Dielectic
Compound XG-3, or equivalent. This should include the ground cable
connector for batteries, engine and cab as well as the jump starting stud.
Accessory feed connections
Vehicle electrical systems are complex and often include electronic
components such as engine and transmission controls, instrument panels,
ABS, etc. While most systems operate on battery voltage (12 volts),
some systems can be as high as 90 volts or as low as five volts. Refer to
the Electrical Circuit Diagram Manuals, available from your vehicle’s
manufacturer, to ensure that any additional body lights and accessories
are connected to circuits that are both appropriate and not overloaded.
No modification should be made to any vehicle control system without
first contacting your dealer.
SUSPENSION INSPECTION
Note:Do not adjust air suspension height to any setting other than the
specified setting. Altering the height setting will change the driveline
angle and may result in unwarrantable component damage, such as
transmission component damage.
Verify drive axle air suspension height and height control valve
performance at engine lube oil change intervals.
Periodically:
•Check condition of spring leaves for evidence of fatigue, bending or
breakage.
•Check condition of suspension mounting brackets and bushings.
•Check that torque rod mounting fasteners are tight.
•Check to be sure the suspension alignment is maintained at all times.
•Check U-bolts after the chassis has been operating under load for
1,000 miles (1,600 km) or six months, whichever comes first, the
U-Bolt nuts must be re-torqued. The U-Bolt nuts thereafter must be
re-torqued every 36,000 miles (58,000 km). The U-Bolt and nut
threads and seats should be cleaned and lubricated to ensure a “like
new” condition when re-torquing.
Note:See theU-Bolt Nut Torquechart later in this section.

FACTORY AUTHORIZED SYSTEMS CHECKS
In the event that your vehicle experiences a component related concern,
please contact your Ford dealership. The Ford Motor Company Trained
Technicians who work at Ford dealerships are specifically trained to
understand your vehicle.
A proper repair begins with a thorough system check. A Factory
Authorized Systems Check can ONLY be found at a Ford dealership. In
some circumstances, the technician may need to request your
authorization to perform additional operations to determine the final
diagnosis. The technician’s goal is to ensure that your vehicle is fixed
right the first time, at the best value to you.
The following list represents several of the Factory Authorized Systems
Checks available at a participating Ford dealers:
•Air Conditioning
•Check Engine Light
•All Wheel Drive and4X4
•Automatic Transmission
•Engine Cooling and Cabin Heating
•Steering and Suspension
•Charge/Start/Battery
•Wheel Alignment
•Anti-Lock Brake System
EMISSIONS CONTROL SYSTEM
To ensure the emissions control systems operate effectively, you should
have the services listed in the maintenance schedule performed at the
specified time and mileage/km 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.
