Purging System (Ford Motor Co. Only)

Air trapped in the power steering system can be removed by using an air evacuation tool. To fabricate an air evacuation tool, a vacuum source capable of drawing 15" of Hg is required (DO NOT use engine vacuum). Connect this vacuum source, using a piece of 1/4-5/16" tubing, to a single hole rubber stopper that is large enough to form a tight seal in the reservoir cap opening.
Fill power steering reservoir to proper level. Raise and support front of vehicle so that front wheels are off of ground. Remove coil wire, crank engine, and recheck fluid level while turning wheels from side to side. Add fluid if necessary. Replace coil wire and insert evacuation tool into reservoir filler.
Start engine and let it idle. Apply vacuum to reservoir for 3 minutes. Recheck fluid level and apply vacuum again. Cycle steering from lock to lock every 30 seconds for 5 minutes. Remove tool, recheck fluid level and add if necessary. Lower vehicle and road test.
