If the level is below the COLD FILL RANGE, add coolant immediately.
SeeAdding Engine Coolantin this chapter.
The coolant concentration should be maintained within 48% to 50%, which
equates to a freeze point between -30 °F (-34 °C) and -34 °F (-37 °C).
Note:For best results, coolant concentration should be tested with a
refractometer such as Robinair Coolant and Battery Refractometer
75240. Ford does not recommend the use of hydrometers or coolant test
strips for measuring coolant concentration.
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, cooling system sealants or additives
as they can cause damage to the engine cooling or 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.

FUEL FILTER
Your vehicle is equipped with a lifetime fuel filter that is integrated with
the fuel tank. Regular maintenance or replacement is not needed.
WASHER FLUID CHECK
WARNING:If you operate your vehicle in temperatures below
40°F (5°C), use washer fluid with antifreeze protection. Failure
to use washer fluid with antifreeze protection in cold weather could
result in impaired windshield vision and increase the risk of injury or
accident.
Add fluid to fill the reservoir if the level is low. Only use a washer fluid
that meets Ford specifications. See the technical specifications chart in
theCapacities and Specificationschapter.
Note:The front and rear washer systems are supplied from the same
reservoir.
State or local regulations on volatile organic compounds may restrict the
use of methanol, a common windshield washer antifreeze additive.
Washer fluids containing non-methanol antifreeze agents should be used
only if they provide cold weather protection without damaging the
vehicle’s paint finish, wiper blades or washer system.
CHANGING THE VEHICLE BATTERY
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 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.
Your vehicle is equipped with a Motorcraft® maintenance-free battery
which normally does not require additional water during its life of service.
Note:If your battery has a cover or a shield, make sure it is reinstalled
after the battery has been cleaned or replaced.
For longer, trouble-free operation, keep the top of the battery clean and
dry. Also, make certain the battery cables are always tightly fastened to
the battery terminals.
If you see any corrosion on the battery or terminals, remove the cables
from the terminals and clean with a wire brush. You can neutralize the
acid with a solution of baking soda and water.
It is recommended that the negative battery cable terminal be
disconnected from the battery if you plan to store your vehicle for an
extended period of time.
Battery relearn
Because your vehicle’s engine is electronically controlled by a computer,
some control conditions are maintained by power from the battery. When
the battery is disconnected or a new battery is installed, the engine must
relearn its idle and fuel trim strategy for optimum driveability and
performance. To begin this process:
1. With the vehicle at a complete stop, set the parking brake.
2. Put the gearshift lever inP(Park), turn off all accessories and start
the engine.
3. Run the engine until it reaches normal operating temperature.
4. Allow the engine to idle for at least one minute.
5. Turn the A/C on and allow the engine to idle for at least one minute.
6. Drive the vehicle to complete the relearning process.
