Power Steering Bleeding: Service and Repair
Special Tools
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.

Use Motorcraft MERCON (R) Multi-Purpose ATF XT-2-QDX or MERCON (R) 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.
