3. Step back while the pressure releases.

• 2.3L coolant bleed valve
5. For the 2.3L engine ONLY, open the coolant bleed valve on the back of
the engine water outlet.
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. For the 2.3L engine ONLY, close the bleed valve.
8. 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.
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.
