Fill Procedure

DESCRIPTION
This procedure is recommended whenever the power steering pump or power rack and pinion steering gear is removed, serviced and installed into the power steering hydraulic system.

MATERIALS REQUIRED
1. A vacuum pump with gauge, capable of pulling 101 kPa (30 in-Hg). The vacuum source should be one of the following:
^ Distributor test machine vacuum pump.
^ Vacuum motor from an air conditioning charging system.
2. A No.7 stopper cap or a special power steering reservoir pump cap assembly with a hose connection.

PREPARATION
1. If the power steering short rack or power steering pump has been changed or flushed, allow old fluid to drain from the system.
2. Tighten all steering system connections.

INITIAL FILL
1. Pour enough steering fluid in the power steering pump reservoir to exceed the amount required for filling the system.
2. Connect vacuum pump to fill part of power steering pump reservoir.
3. Start the vacuum pump. Operate the pump until a gauge reading of 84-101 kPa (25-30 in-Hg) is obtained.
4. Shut off the vacuum pump. Watch the gauge for approximately 30 seconds. If the vacuum reading drops more than 3 kPa (1 in-Hg), there is a leak in the power steering or filling system that must be corrected.

FINAL FILL
1. Adjust fluid level in power steering pump reservoir to correct level. There will be a slight drop in the level when the engine is first started and the steering wheel is cycled. Steps After Repairs (Start-Up Procedure)
2. Operate the engine at an idle for 15 minutes then inspect for leaks.
