Ford Five Hundred (2007 year). Manual — part 63

8. Add coolant/water mixture
through the thermostat housing
opening until full at housing
opening.

9. Install the thermostat housing
bleed plug. Install metal pin by
pushing into the slot.

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.

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.

Maintenance and Specifications

254

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 Maintenance product specifications and 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.

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%.

• Decreased engine coolant concentrations below 40% will

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

Maintenance and Specifications

255

• Decreased engine coolant concentrations below 40% will

decrease the freeze 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
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.

FUEL FILTER
For fuel filter replacement, see your authorized dealer. Refer to
scheduled maintenance information for the appropriate intervals for
changing the fuel filter.
Replace the fuel filter with an authorized Motorcraft part. The
customer warranty may be void for any damage to the fuel system
if an authorized Motorcraft fuel filter is not used.

WHAT YOU SHOULD KNOW ABOUT AUTOMOTIVE FUELS

Important safety precautions

Do not overfill the fuel tank. The pressure in an overfilled tank
may cause leakage and lead to fuel spray and fire.

The fuel system may be under pressure. If the fuel filler cap is
venting vapor or if you hear a hissing sound, wait until it stops

before completely removing the fuel filler cap. Otherwise, fuel may
spray out and injure you or others.

If you do not use the proper fuel filler cap, excessive vacuum in
the fuel tank may damage the fuel system or cause the fuel cap

to disengage in a collision, which may result in possible personal injury.

Automotive fuels can cause serious injury or death if misused or
mishandled.

Gasoline may contain benzene, which is a cancer-causing agent.

Maintenance and Specifications

256

Observe the following guidelines when handling automotive fuel:
• Extinguish all smoking materials

and any open flames before
refueling your vehicle.

• Always turn off the vehicle before

refueling.

• Automotive fuels can be harmful

or fatal if swallowed. Fuel such as gasoline is highly toxic and if
swallowed can cause death or permanent injury. If fuel is swallowed,
call a physician immediately, even if no symptoms are immediately
apparent. The toxic effects of fuel may not be visible for hours.

• Avoid inhaling fuel vapors. Inhaling too much fuel vapor of any kind

can lead to eye and respiratory tract irritation. In severe cases,
excessive or prolonged breathing of fuel vapor can cause serious
illness and permanent injury.

• Avoid getting fuel liquid in your eyes. If fuel is splashed in the eyes,

remove contact lenses (if worn), flush with water for 15 minutes and
seek medical attention. Failure to seek proper medical attention could
lead to permanent injury.

• Fuels can also be harmful if absorbed through the skin. If fuel is

splashed on the skin and/or clothing, promptly remove contaminated
clothing and wash skin thoroughly with soap and water. Repeated or
prolonged skin contact with fuel liquid or vapor causes skin irritation.

• Be particularly careful if you are taking “Antabuse” or other forms of

disulfiram for the treatment of alcoholism. Breathing gasoline vapors,
or skin contact could cause an adverse reaction. In sensitive
individuals, serious personal injury or sickness may result. If fuel is
splashed on the skin, promptly wash skin thoroughly with soap and
water. Consult a physician immediately if you experience an adverse
reaction.

When refueling always shut the engine off and never allow
sparks or open flames near the filler neck. Never smoke while

refueling. Fuel vapor is extremely hazardous under certain conditions.
Care should be taken to avoid inhaling excess fumes.

The flow of fuel through a fuel pump nozzle can produce static
electricity, which can cause a fire if fuel is pumped into an

ungrounded fuel container.
