WARNING:The use of inferior parts can adversely affect the
quality and reliability of your vehicle which, in turn, can result in
property damage, personal injury or death.
To avoid damage to the vehicle’s electrical components prior to electric
welding:
•disconnect both battery cables.
•attach the welder ground cable as close as possible to the part being
welded.
•it is recommended that the component be temporarily removed if
welding close to an electrical component.
Follow the checks and services in theScheduled Maintenancechapter.
Have your dealer or service center inspect your vehicle at least once a
year. Remember that regular maintenance and inspections usually
prevent serious problems from developing later.
If the owner or operator of the vehicle is a skilled technician and intends
on performing the vehicle maintenance and service, he is strongly urged
to purchase a service manual.
Electrical System
Periodically inspect electrical connectors on the outside of the cab and
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 powertrain
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. See theElectrical Circuit Diagram Manuals,available from your
vehicle’s manufacturer, to make sure 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.

Note:For best results, coolant concentration should be tested with a
refractometer such as Rotunda tool 300-ROB75240E available from your
dealer. Ford does not recommend the use of hydrometers or coolant test
strips for measuring coolant concentrations.
Note:Automotive fluids are not interchangeable; do not use engine
coolant, antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
Adding Engine Coolant
WARNING:Do not add engine coolant when the engine is hot.
Steam and scalding liquids released from a hot cooling system
can burn you badly. Also, you can be burned if you spill coolant on hot
engine parts.
WARNING:Do not put engine coolant in the windshield washer
fluid container. If sprayed on the windshield, engine coolant
could make it difficult to see through the windshield.
WARNING:To reduce the risk of personal injury, make sure the
engine is cool before unscrewing the coolant pressure relief cap.
The cooling system is under pressure; steam and hot liquid can come
out forcefully when the cap is loosened slightly.
WARNING:Do not add coolant further than the MAX mark.
Note:
Do not use stop leak pellets or cooling system sealants or additives
as they can cause damage to the engine cooling and heating systems. This
damage would not be covered under your vehicle’s warranty.
Note:During normal vehicle operation, the engine coolant may change
color from orange to pink or light red. As long as the engine coolant is
clear and uncontaminated, this color change does not indicate the engine
coolant has degraded nor does it require the engine coolant to be
drained, the system to be flushed, or the engine coolant to be replaced.
•DO NOT MIX different colors or types of coolant in your vehicle.
Make sure the correct coolant is used. Mixing of engine coolants may
harm your engine’s cooling system. The use of an improper coolant
may harm engine and cooling system components and may void the
warranty.

CHANGING THE VEHICLE BATTERY
WARNING:This vehicle may be equipped with more than one
battery, removal of cable from only one battery does not
disconnect the vehicle electrical system. Be sure to disconnect cables
from all batteries when disconnecting power. Failure to do so may
cause serious personal injury or property damage.
WARNING:Batteries normally produce explosive gases which
can cause personal injury. Therefore, do not allow flames, sparks
or lighted substances to come near the battery. When working near the
battery, always shield your face and protect your eyes. Always provide
proper ventilation.
WARNING:When lifting a plastic-cased battery, excessive
pressure on the end walls could cause acid to flow through the
vent caps, resulting in personal injury and/or damage to the vehicle or
battery. Lift the battery with a battery carrier or with your hands on
opposite corners.
WARNING:Keep batteries out of reach of children. Batteries
contain sulfuric acid. Avoid contact with skin, eyes or clothing.
Shield your eyes when working near the battery to protect against
possible splashing of acid solution. In case of acid contact with skin or
eyes, flush immediately with water for a minimum of 15 minutes and
get prompt medical attention. If acid is swallowed, call a physician
immediately.
WARNING:Battery posts, terminals and related accessories
contain lead and lead compounds. Wash hands after handling.
Note:If your battery has a cover/shield, make sure it is reinstalled after
the battery has been cleaned or replaced.
Note:Electrical or electronic accessories or components added to the
vehicle by the dealer or the owner may adversely affect battery
performance and durability.

WARNING(Continued)
•Do not change from aluminum wheels to steel wheels or vice-versa
without changing the mounting hardware where required or, in some
cases with flange nut mounting systems, changing the hub and stud
assembly. Mixing components could cause wheel or fastener failures
and result in property damage, personal injury, or death.
WARNING:An inflated tire and rim can be very dangerous if
improperly used, serviced or maintained. To avoid serious injury,
never attempt to re-inflate a tire which has been run flat or seriously
under-inflated without first removing the tire from the wheel assembly
for inspection. Do not attempt to add air to tires or replace tires or
wheels without first taking precautions to protect persons and property.
All tires with Steel Carcass Plies (if equipped):This type of tire
utilizes steel cords in the sidewalls. As such, they cannot be treated like
normal light truck tires. Tire service, including adjusting the air pressure,
must be performed by personnel trained, supervised and equipped
according to Federal Occupational Safety and Health Administration
(OSHA) regulations. For example, during any procedure involving tire
inflation, the technician or individual must utilize a remote inflation
device, and make sure that all persons are clear of the trajectory area.

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.
TECHNICAL SPECIFICATIONS
Wheel Lug Nut Torque Specifications
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.
