Quality service parts are available through an authorized dealer. If dealer
parts are not used, make sure the replacement parts are of equivalent
quality.
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 your vehicle’s electrical components before electric
welding:
•Disconnect both battery cables.
•Attach the welder ground cable as close as possible to the part being
welded.
•We recommend temporarily removing the component if welding close
to an electrical component.
Follow the checks and services in theScheduled Maintenancechapter.
Have an authorized 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 Dielectric
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
and ABS. 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 the
Electrical Circuit Diagram Manuals,available from your vehicle’s
manufacturer, to make sure that any extra body lights and accessory
connections to circuits are both appropriate and not overloaded. Do not
make modifications to any vehicle control system without first contacting
an authorized dealer.

Gasoline Engine
Checking the Engine Coolant
When the engine is cold, check the concentration and level of engine
coolant at the intervals listed in theScheduled Maintenancechapter.
Note:Make sure that the level is between the MIN and MAX marks on
the coolant reservoir.
Note:Coolant expands when it is hot. The level may extend beyond the
MAX mark.
Note:If the level is at the MIN mark, below the MIN mark, or empty,
add coolant immediately. SeeAdding engine coolantin this section.
Note:For best results, coolant concentration should be tested with a
refractometer such as Rotunda tool 300-ROB75240 available from an
authorized 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. Your vehicle’s warranty does not cover this damage.
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 draining the engine coolant,
flushing the system, or replacing the engine coolant.
•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. Use prediluted engine coolant meeting the Ford
specification. See theCapacities and Specificationschapter for
more information.
•In case of emergency, you may add a large amount of water without
engine coolant in order to reach a vehicle service location. In this
instance, drain the cooling system, chemically clean it with Motorcraft
Premium Cooling System Flush, and refill it with engine coolant as
soon as possible. Water alone (without engine coolant) can cause
engine damage from corrosion, overheating or freezing.
•Do not use alcohol, methanol, brine or any engine coolants mixed
with alcohol or methanol antifreeze (coolant). Alcohol and other
liquids can cause engine damage from overheating or freezing.
•Do not add extra inhibitors or additives to the coolant. These can be
harmful and compromise the corrosion protection of the engine
coolant.
Unscrew the cap slowly. Any pressure escapes as you unscrew the cap.
Add prediluted engine coolant meeting the Ford specification. See
Capacities and Specificationsfor more information.
Whenever you add coolant, check the coolant level in the coolant
reservoir the next few times you drive your vehicle. If necessary, add
enough prediluted engine coolant to bring the coolant level to the proper
level.
Recycled Engine Coolant
Ford Motor Company does not recommend the use of recycled engine
coolant since a Ford-approved recycling process is not yet available.
Dispose of used engine coolant in an appropriate manner. Follow your
community’s regulations and standards for recycling and disposing of
automotive fluids.

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 or shield, make sure to reinstall it after
cleaning or replacing the battery.
Note:Electrical or electronic accessories or components added to your
vehicle by an authorized dealer or the owner may adversely affect
battery performance and durability.
