You did use power steering fluid? This is an oil, it does not boil, it airates(bubles) When all these parts are changed getting all air out of the system can be tough, a vacuum pump method is prefered, but you might be able to do it by turning the wheel full from stop to stop for at least 5 minutes, do not hold wheel against the stops, as this can destroy the pump seals. Bulletin No.: 93-26-5 Date: December 22, 1993 This bulletin supersedes the following Technical Service Bulletins: 93-7-3 dated March 31, 1993 93-3-4 dated February 3, 1993 92-21-2 dated October 7, 1992. SERVICE INFORMATION ISSUE Noise heard from the Power Steering Pump may be caused by air in the system. ACTION Purge all air from the system to eliminate any noise caused by air. Perform the following "Purge Air From Power Steering System" service procedure for either of the following conditions: For all power steering noise complaints and evidence of aerated fluid. If noise persists, proceed with service diagnostics and repair procedures. For all vehicles following the disconnecting/decoupling of any power steering hydraulic connections/couplings. This does not include fluid top off procedures. FLUID LEVEL TOP OFF - PROCEDURE 1. Check and fill pump reservoir to dipstick FULL COLD or remote reservoir center mark. 2. Disable ignition by disconnecting the EDIS/DIS/TFI module or, for remote TFI, disconnect CMP/Hall Effect/PIP sensor. 3. Crank engine 30 seconds, check fluid level and add if required. 4. Crank engine 30 seconds while cycling the steering wheel lock to lock. NOTE: If the air is not purged from the power steering system correctly, a second customer concern or pump failure could result. This condition can only occur on vehicles with evidence of aerated fluid or vehicles that have had steering component service. NOTE: On 7.3L diesel vehicles, the fuel shutoff solenoid (on the injection pump) must be disconnected to prevent starting. NOTE: Do not hold steering wheel on stops. Page 1 of 2 1/16/2010 ...5. Check fluid level and add fluid if required. AIR PURGE WITH VACUUM EXTERNAL SOURCE - PROCEDURE 1. Tightly insert the rubber stopper of the air evacuator assembly into pump reservoir. 2. Reconnect connection used to disable ignition and start vehicle. 3. Apply 20-25 in-Hg. (68-85 kPa) maximum vacuum for minimum of three minutes at idle; maintain maximum vacuum with vacuum source. Refer to Fig. 1 . 4. Release vacuum and remove vacuum source. 5. Add fluid to FULL WARM or reservoir center mark. 6. Re-install vacuum source and apply 20-25 in-Hg (68-85 Kpa) vacuum. 7. Cycle steering wheel from lock to lock every 30 seconds for approximately 5 minutes. 8. Shut engine off, release vacuum and remove vacuum source. 9. Add fluid if necessary and install dipstick or reservoir cap. 10. Start engine and cycle steering wheel from lock to lock every 30 seconds for approximately 5 minutes. 11. Check for oil leaks at all connections. NOTE: Do not hold steering wheel on stops. NOTE: Do not hold steering wheel on stops. NOTE: In severe cases it may be necessary to repeat air purge with vacuum source procedure.
