2001 Toyota 4Runner Power Steering Pump Parts Questions & Experts Answers

• Q: How to service and repair the power steering pump on 2001 Toyota 4Runner?

  A: Begin the service and repair work on the power steering pump by unscrewing its air cleaner assembly through the removal of three bolts. Before you disconnect the return hose you should remove its clip but keep the drive belt clean from any fluid spillage. The service requires disconnecting the oil pressure switch through connector removal from the pressure feed tube while preventing drops of the switch unit; if damage occurs replace the switch with a new one. You should remove the pressure feed tube by disassembling its union bolt along with the gasket. The drive belt removal process starts by loosening nut "B" and bolt "A" before easing bolt "C." The next step requires the PS vane pump assembly removal through bolt "A" followed by nut "B" before finally removing the whole assembly itself. Beginning with installing the PS vane pump assembly allows you to tighten bolt "A" and nut "B" temporarily before adjusting drive belt tension by tightening bolt "C." Finally, torque bolt "A" and nut "B" to 43 Nm (440 kgf-cm, 32 ft. lbs.). Before tightening the union bolt to 47 Nm (480 kgf-cm, 35 ft. lbs.), install a new gasket and the union bolt onto the pressure feed tube while ensuring that the stopper rests against the PS vane pump body walls. Apply torque of 21 Nm (210 kgf-cm, 15 ft. lbs.) to the installed oil pressure switch on the pressure feed tube before reconnecting the connector by keeping oil away from it. The return hose should be connected while installing the clip before reinstalling the air cleaner assembly using the 3 bolts. Bleeding should occur as the final step in the power steering system maintenance process.
