relearn the idle and fuel trim strategy.
•If you do not allow the engine to relearn its idle trim, the idle
quality of your vehicle may be adversely affected until the idle
trim is eventually relearned.
If the battery has been disconnected or a new battery has been installed,
the clock and radio settings must be reset once the battery is
reconnected.
•Always dispose of automotive
batteries in a responsible manner.
Follow your local authorized
standards for disposal. Call your
local authorized recycling center
to find out more about recycling
automotive batteries.
ENGINE COOLANT
Checking engine coolant
The concentration and level of engine coolant should be checked at the
intervals listed inscheduled maintenance information.The coolant
concentration should be maintained at 50/50 coolant and distilled water,
which equates to a freeze point of -34°F (-36°C). Coolant concentration
testing is possible with a hydrometer or antifreeze tester. The level of
coolant should be maintained at the FULL COLD level or within the
COLD FILL RANGE in the coolant reservoir. If the level falls below, add
coolant per the instructions in theAdding engine coolantsection.
Your vehicle was factory-filled with a 50/50 engine coolant and water
concentration. If the concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not work properly.A
50/50 mixture of coolant and water provides the following:
•Freeze protection down to -34°F (-36°C).
•Boiling protection up to 265°F (129°C).

•Protection against rust and other forms of corrosion.
•Proper function of calibrated gauges.
When the engine is cold, check the
level of the engine coolant in the
reservoir.
•The engine coolant should be at the FULL COLD level, or within the
COLD FILL or MIN / MAX range as listed on the engine coolant
reservoir (depending upon application).
•Refer toscheduled maintenance informationfor service interval
schedules.
If the engine coolant has not been checked at the recommended interval,
the engine coolant reservoir may become low or empty. If the reservoir is
low or empty, add engine coolant to the reservoir. Refer toAdding
engine coolantin this chapter.
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
When adding coolant, make sure it is a 50/50 mixture of engine coolant
and distilled water. Add the mixture to the coolant reservoir,when the
engine is cool,until the appropriate fill level is obtained. If coolant is
filled to the COLD FILL RANGE or FULL COLD level when the engine is
not cool, the system will remain underfilled.
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.
•DO NOT MIXdifferent colors or types of coolant in your vehicle.
Make sure the correct coolant is used.DO NOT MIXrecycled coolant
and new (unused) coolant together in the vehicle. 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. Refer toMaintenance product
specifications and capacitiesin this chapter.
Note:Do not use stop leak pellets or cooling system sealants/additives
as they can cause damage to the engine cooling and/or heating systems.
This damage would not be covered under your vehicle’s warranty.
•A large amount of water without engine coolant may be added, in case
of emergency, to reach a vehicle service location. In this instance, the
cooling system must be drained and refilled with a 50/50 mixture of
engine coolant and distilled water 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.
For vehicles with overflow coolant systems with a non-pressurized cap
on the coolant recovery system, add coolant to the coolant recovery
reservoir when the engine is cool. Add the proper mixture of coolant and
distilled water to the FULL COLD level. For all other vehicles which have
a coolant degas system with a pressurized cap, or if it is necessary to
remove the coolant pressure relief cap on the radiator of a vehicle with
an overflow system, follow these steps to add engine coolant.
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.

Add the proper mixture of coolant and water to the cooling system by
following these steps:
1. Before you begin, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the coolant
pressure relief cap on the coolant reservoir (a translucent plastic bottle).
Slowly turn cap counterclockwise (left) until pressure begins to release.
3. Step back while the pressure releases.
4. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
5. Fill the coolant reservoir slowly with the proper coolant mixture, to
within the COLD FILL RANGE or the FULL COLD level on the reservoir.
If you removed the radiator cap in an overflow system, fill the radiator
until the coolant is visible and radiator is almost full.
6. Replace the cap. Turn until tightly installed. Cap must be tightly
installed to prevent coolant loss.
After any coolant has been added, check the coolant concentration (refer
toChecking engine coolant). If the concentration is not 50/50
(protection to –34°F/–36°C), drain some coolant and adjust the
concentration. It may take several drains and additions to obtain a 50/50
coolant concentration.
Whenever coolant has been added, the coolant level in the coolant
reservoir should be checked the next few times you drive the vehicle. If
necessary, add enough 50/50 concentration of engine coolant and
distilled water to bring the liquid level to the proper level.
If you have to add more than 1.0 quart (1.0 liter) of engine coolant per
month, have your authorized dealer check the engine cooling system.
Your cooling system may have a leak. Operating an engine with a low
level of coolant can result in engine overheating and possible engine
damage.
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.
Used engine coolant should be disposed of in an appropriate
manner. Follow your community’s regulations and standards for recycling
and disposing of automotive fluids.
Coolant refill capacity
To find out how much fluid your vehicle’s cooling system can hold, refer
toMaintenance product specifications and capacitiesin this chapter.

Severe climates
If you drive in extremely cold climates (less than –34°F [–36°C]):
•It may be necessary to increase the coolant concentration
above 50%.
•NEVER increase the coolant concentration above 60%.
•A coolant concentration of 60% will provide freeze point
protection down to -62°F [-52°C]. Increased engine coolant
concentrations above 60% will decrease the overheat
protection characteristics of the engine coolant and may cause
engine damage.
•If available, refer to the chart on the coolant container to
ensure the coolant concentration in your vehicle will provide
adequate freeze protection at the temperatures in which you
drive in the winter months.
If you drive in extremely hot climates:
•It is still necessary to maintain the coolant concentration
above 40%.
•NEVER decrease the coolant concentration below 40%.
•A coolant concentration of 40% will provide freeze point
protection down to -12°F [-24°C]. Decreased engine coolant
concentrations below 40% will decrease the corrosion/freeze
protection characteristics of the engine coolant and may cause
engine damage.
•If available, refer to the chart on the coolant container to
ensure the coolant concentration in your vehicle will provide
adequate protection at the temperatures in which you drive.
Vehicles driven year-round in non-extreme climates should use a 50/50
mixture of engine coolant and distilled water for optimum cooling system
and engine protection.
What you should know about fail-safe cooling
If the engine coolant supply is depleted, this feature allows the vehicle to
be driven temporarily before incremental component damage is incurred.
The “fail-safe” distance depends on ambient temperatures, vehicle load
and terrain.
