WINDSHIELD WASHER FLUID

Add fluid to fill the reservoir if the
level is low. In very cold weather, do
not fill the reservoir completely.

Only use a washer fluid that meets
Ford specification WSB-M8B16-A2.
Do not use any special washer fluid
such as windshield water repellent
type fluid or bug wash. They may
cause squeaking, chatter noise,
streaking and smearing. Refer to the
Lubricant specifications section in
this chapter.

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.

If you operate your vehicle in temperatures below 40° F (4.5°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.

Note: Do not put washer fluid in the engine coolant reservoir. Washer
fluid placed in the cooling system may harm engine and cooling system
components.

Engine oil and filter recommendations

Look for this certification
trademark.

Use SAE 5W-20 engine oil.

Only use oils “Certified For Gasoline Engines” by the American
Petroleum Institute (API). An oil with this trademark symbol conforms
to the current engine and emission system protection standards and fuel
economy requirements of the International Lubricant Standardization and
Approval Committee (ILSAC), comprised of U.S. and Japanese
automobile manufacturers.

To protect your engine’s warranty use Motorcraft SAE 5W-20 or an
equivalent SAE 5W-20 oil meeting Ford specification WSS-M2C930-A.
SAE 5W-20 oil provides optimum fuel economy and durability
performance meeting all requirements for your vehicle’s engine.

Do not use supplemental engine oil additives, cleaners or other engine
treatments. They are unnecessary and could lead to engine damage that
is not covered by Ford warranty.

Change your engine oil according to the appropriate schedule listed in
the scheduled maintenance information.

Ford production and aftermarket (Motorcraft) oil filters are designed for
added engine protection and long life. If a replacement oil filter is used
that does not meet Ford material and design specifications, start-up
engine noises of knock may be experienced.

It is recommended you use the appropriate Motorcraft oil filter (or
another brand meeting Ford specifications) for your engine application.

BATTERY

Your vehicle is equipped with a
Motorcraft maintenance-free battery
which normally does not require
additional water during its life of
service.

If your battery has a cover/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.

Note: Electrical or electronic accessories or components added to
the vehicle by the dealer or the owner may adversely affect
battery performance and durability.

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.

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.

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.

Battery posts, terminals and related accessories contain lead and
lead compounds. Wash hands after handling.

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 in P (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. Release the parking brake. With your foot on the brake pedal and with
the A/C on, put the vehicle in D (Drive) and allow the engine to idle for
at least one minute.

7. Drive the vehicle to complete the relearning process.
• The vehicle may need to be driven 10 miles (16 km) or more to

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.

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 in scheduled 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 (such as the
Rotunda Battery and Antifreeze Tester, 014–R1060). 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 the Adding engine coolant section.

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.
• Enables calibrated gauges to work properly.

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 RANGE” as listed on the engine coolant reservoir
(depending upon application).

• Refer to scheduled maintenance information for service interval

schedules.

• Be sure to read and understand Precautions when servicing your

vehicle in this chapter.

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 to Adding
engine coolant in 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.

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.

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.

• Add Motorcraft Premium Gold Engine Coolant or equivalent

meeting Ford specification WSS-M97B51-A1. Refer to Lubricant
specifications in this chapter.

Note: Use of Motorcraft Cooling System Stop Leak Pellets or an
equivalent product meeting Ford specification WSS-M99B37-B6, may
darken the color of Motorcraft Premium Gold Engine Coolant from
yellow to golden tan.

Note: When adding more than 1 quart (.95L) of coolant it is necessary
to use the coolant bleed valve. Failure to bleed the cooling system when
adding engine coolant may cause engine damage. Refer to the Cooling
section of the Workshop Instruction.
• Do not add/mix an orange-colored, extended life coolant such

as Motorcraft Specialty Orange Engine Coolant, meeting Ford
specification WSS-M97B44-D, with the factory-filled coolant.
Mixing Motorcraft Specialty Orange Engine Coolant or any
orange-colored extended life product with your factory filled coolant
can result in degraded corrosion protection.

• 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.

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.

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 (an opaque 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.
• 2.3L coolant bleed valve

• 3.0L coolant bleed valve

5. Open the coolant bleed valve on the back of the engine water outlet
for the 2.3L engine or the coolant bleed valve located on the upper
radiator hose for the 3.0L engine.

6. Fill the coolant reservoir slowly with the proper coolant mixture (see
above), to within the “COLD FILL RANGE” or the “FULL COLD” level on
the reservoir.

7. Close the bleed valve and reinstall the cap on the coolant reservoir.
Turn the cap until it is tightly installed to prevent coolant loss.

After any coolant has been added, check the coolant concentration.
Refer to the Checking engine coolant section. 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.

Maintenance and Specifications

223

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 in vehicles originally equipped with Motorcraft Premium Gold
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
to Refill capacities in this chapter.

Fill your engine coolant reservoir as outlined in Adding engine coolant
in this section.

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%.
• Increased engine coolant concentrations above 60% will

decrease the overheat protection characteristics of the engine
coolant and may cause engine damage.

• 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.
