GENERAL PROCEDURES
System Flushing —
CIII 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 could 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.

CAUTION: Do not overfill the reservoir.
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.
10. Install the fuel pump fuse.
11. 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.
Start the engine and turn the steering wheel from stop- to-stop.
12. CAUTION: Do not overfill the reservoir.
NOTE: If the power steering system is noisy and is accompanied by evidence of aerated fluid it
will be necessary to purge the power steering system.
Check the fluid level. If necessary, fill the reservoir to the correct level.

GENERAL PROCEDURES
Purging —CII Power Steering Pump
CAUTION: If the air is not purged from the power steering system correctly, premature
power steering pump failure can result. This condition can occur on pre- delivery vehicles with
evidence of aerated fluid or on vehicles that have had steering component repairs.
1. NOTE: A whine heard from the power steering pump may be caused by air in the system. The
power steering purge procedure must be performed prior to any component repair for which
power steering noise complaints are accompanied by evidence of aerated fluid.
Remove the reservoir cap. 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.
2. Tightly insert the Vacuum Pump stopper into the reservoir.
3. Start the vehicle.
4. Using the special tool, apply maximum vacuum and maintain it for a minimum of three minutes with the engine speed set at idle. SECTION 211-

8.
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.
Cycle the steering wheel fully to the left and right every 30 seconds for approximately five
minutes.
9. Stop the engine, release the vacuum, and remove the special tool.
10. Install the reservoir cap.
11. Check for fluid leaks at all of the connections. If the power steering fluid shows signs of air, repeat this procedure. Klj . 3 ba
