This bulletin supersedes Technical Bulletin Group 4, Number 9006, dated August 7, 1990.
Concern:
Proper cleaning of system when replacing power steering pumps.
Repair Procedure:
Whenever a power steering pump is replaced, the hose from the reservoir to the pump, the hose from the pump
to the rack, and the hose from the rack to the reservoir*, all have to be flushed out with clean solvent to ensure
that no foreign material is in the system. The oil reservoir must be replaced because it is not serviceable.
*The return line from the rack to the reservoir includes the oil cooler and is more easily cleaned in place on the
car.
