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-
