Fill the pump reservoir with fluid to the FULL COLD level.
Attach the Power Steering Bleeder Adapter J-43485 to the Mityvac J-35555 or equivalent.
Place the Power Steering Bleeder Adapter J-43485 on or in the pump reservoir filler neck.
Apply a vacuum of  up to 20 inch Hg (68 kPa) maximum

Wait 5 minutes.

Remove the Power Steering Bleeder Adapter J-43485 and the Metal Mityvac J-35555.
Top up fluid as necessary.
Reinstall the pump reservoir cap.

Start the engine. Allow the engine to idle.
Turn off the engine.

Verify the fluid level. Repeat Previous Section.

Remove the pump reservoir cap.

Attach the Power Steering Bleeder Adapter J-43485 to the Metal Mityvac J-35555 or equivalent
Place the Power Steering Bleeder Adapter J-43485 on or in the pump reservoir filler neck.
Apply a vacuum of  up to 20 inch Hg (68 kPa) maximum.
Wait 5 minutes.
There should be no drop in vacuum.
A drop in vacuum indicates a leak in the power steering system and should be repaired before continuing.
A leak in the power steering system will create noise from the power steering pump and possible premature failure of the steering
hydraulic system.
If no leaks were found remove the Power Steering Bleeder Adapter J-43485 and the Metal Mityvac J-35555.
Verify the fluid level.  Reinstall the pump reservoir cap.
