GENERAL PROCEDURES
Hydro-
Boost Bleeding
1. NOTE: The Hydro- Boost power brake booster (2B560) is generally self- bleeding, and the
following procedure will normally bleed the air from the power brake booster. Normal operation
of the vehicle will further remove any additional trapped air.
Fill the power steering oil reservoir (3A697) with MERCON® Multi- Purpose ATF XT-2-QDX or
MERCON® equivalent.
2. Remove the powertrain control module (PCM) fuse to prevent the engine from starting.
3. Crank the engine for several seconds.
4. Check the fluid level in the power steering oil reservoir and add if necessary. Install the powertrain control module (PCM) fuse.
5. Start the engine.
6. With the engine running, turn the steering wheel (3600) from stop- to-stop twice. Turn the engine
off.
7. Depress the brake pedal (2455) several times to discharge the accumulator.
8. Repeat Steps 5 and 6.
9. If foaming occurs, stop the engine and allow the foam to dissipate.
10. Repeat Steps 5 and 6 as required, until all the air is removed from the system (when the foaming stops).

GENERAL PROCEDURES
System Flushing —
CII Power Steering Pump
WARNING: Do not mix oil types. Any mixture or any unapproved oil can lead to seal
deterioration and leaks. A leak can ultimately cause loss of fluid, which can result in a loss of
power steering assist.
1. Remove the fuel pump fuse from the battery junction box.
2. Disconnect the power steering return hose. Plug the reservoir.
3. Attach an extension hose between the power steering return hose and an empty container.
4. Raise the front wheels off the floor. For additional information, refer to Section 100 - 02 .
5. Check the fluid level. If necessary, fill the reservoir to the correct level. zUse Motorcraft MERCON® Multi-Purpose ATF XT -2-QDX or MERCON® equivalent.
6. CAUTION: Do not crank the engine for more than 15 seconds at a time. Allow the
starter to cool for 1 minute before cranking again. Premature starter failure can occur.
CAUTION: Do not hold the steering wheel against the stops for more than three to
five seconds at a time. Damage to the power steering pump will occur.
Turn the steering wheel from stop- to-stop while cranking the engine until the fluid exiting the
power steering return hose is clear of all contamination and foreign material.
zAdd Motorcraft MERCON® Multi-Purpose ATF XT -2-QDX or MERCON® equivalent as
needed.
7. Lower the vehicle.
8. Disconnect the extension hose from the power steering return hose. Remove the plug. Attach the power steering return hose to the reservoir.
