2000 Toyota Avalon Parts Questions & Experts Answers

• Q: How to service and repair the power steering pump on 2000 Toyota Avalon?

  A: You must start power steering pump maintenance by removing the front fender apron seal RH and its 2 bolts. Begin the procedure by completely removing the return hose adapter along with its clip while being watchful of fluid spillage onto the drive belt. Start by removing the 2 clamp plate set nuts and proceed to disconnect the bolt and complete removal of the 2 clamp plates together with the 2 holders from the pressure feed tube. A spanner should steady the pressure feed tube during its removal with Special Service Tool: 09631-22020. Remove the drive belt by turning loose the 2 bolts as you disconnect the oil pressure switch connector and only partially loosen bolt A because complete removal of bolt A is not possible. Begin by removing bolt B together with the PS vane pump assembly before extracting the oil pressure switch with caution to replace if the component sustains any damage. Start by taking out the oil pressure switch from the union bolt after which follow the union bolt and gasket and associated pressure feed tube removal. Install the pressure feed tube combined with gasket onto the PS vane pump assembly using a union bolt while maintaining the stopper in contact with the front bracket before torquing to 52 Nm (525 kgf.cm, 38 ft. lbs.). Attach the oil pressure switch while torquing it to 21 Nm (210 kgf.cm, 15 ft. lbs.) with caution to prevent oil seal attachment to the connector. The installation process requires temporary bolt attachment of PS vane pump assembly components A and B followed by a torque adjustment of bolt A using Special Service Tool: 09249-63010 until reaching 29 Nm (293 kgf.cm, 21 ft. lbs.) while the final step includes bolt B torquing to 43 Nm (440 kgf.cm, 32 ft. lbs.) and connection of the oil pressure switch connector. The pressure feed tube requires a spanner tool for steady connection through Special Service Tool: 09631-22020 and should be torqued to 20 Nm (203 kgf.cm, 15 ft. lbs.). Fasten a bolt into each holder and clamp plate of the pressure feed tube before tightening the nuts to 7.8 Nm (80 kgf.cm, 69 inch lbs.). The return hose requires clippage after which the front fender apron seal RH gets installed with 2 bolts while the power steering system needs pressure bleeding.
