Q: How to service and repair the power steering pump on Toyota 4Runner?
A: The power steering pump service requires draining the power steering fluid first. Release the tension on the belt tensioner counterclockwise to take out the air cleaner assembly and vane pump V belt. unning the pump requires the operator to release two clips and disconnect two vacuum hoses before releasing a third clip and disconnection of the hose from the oil reservoir to pump hose No. 1. The next procedure requires removal of the union bolt along with gasket for pressure feed tube assembly separation and tube disconnection. The vane pump assembly removal requires the user to remove its two bolts and nut before using a "torx" socket (E10) to loosen the stud bolt.
Q: How to service and repair the power steering pump on Toyota Camry?
A: Service and repair of the power steering pump starts with removing the front fender apron seal on the right-hand side through the removal of its 2 bolts. According to the steps unique to 5S-FE and 1MZ-FE engines you must first remove various clamps and holders then use Special Service Tool: 09023-12700 to disconnect the tube. After loosening the 2 bolts marked as A and B on the drive belt you can remove the belt. Then proceed to take out the PS vane pump assembly with pressure feed tube by disconnecting the oil pressure switch connector and loosening bolt A, which remains on the align. Toward the end of pressure feed tube removal disconnect the oil pressure switch from the union bolt while being cautious about dropping it before you take out the union bolt and gasket. Begin installing the pressure feed tube by adding a new gasket then position its stopper against the front bracket before torquing the union bolt to 52 Nm (525 kgf-cm, 38 ft. lbs.). Affix the oil pressure switch into the union bolt section while tightening it to 21 Nm (210 kgf-cm, 15 ft. lbs.). First install the PS vane pump assembly along with the pressure feed tube and tighten the 2 bolts A and B in a temporary manner. Then install the drive belt after adjusting its tension. Torque bolt A to 29 Nm (293 kgf-cm, 21 ft. lbs.) while using Special Service Tool: 09249-63010. Disconnect the clamp with engine wire when working on the 1MZ-FE engine. Apply 43 Nm (440 kgf-cm, 32 ft. lbs.) torque along with a connector connection to the oil pressure switch after ensuring the connector remains free from oil contamination. The pressure feed tube requires installation with Special Service Tool: 09023-12700 while torquing it to 23 Nm (235 kgf-cm, 17 ft. lbs.) and maintaining tool parallelness to the torque wrench. The tube clamp must be attached first on the 5S-FE engine followed by installing 2 clamp plates and 2 holders before tightening the clamp plate set bolt and nut to 10 Nm (100 kgf-cm, 7 ft. lbs.). Precise installation of the 1MZ-FE engine includes the placement of 2 clamp plates with 2 holders while tightening the bolt followed by torquing 2 clamp plate set nuts to 7.8 Nm (80 kgf-cm, 69 inch lbs.). The power steering system bleed process needs completion and the right-hand front fender apron seal needs 2 bolts tightening together with the return hose connection.
Q: How to service and repair the power steering pump on Toyota Tacoma?
A: The power steering pump repair starts with drive belt removal after unscrewing both the power steering idle pulley set bolt and belt adjusting bolt. Apply a spanner (24 mm) onto the pressure port union to disconnect the pressure feed tube by removing the union bolt and two required gaskets. Wipe off all fluid from the drive belt before disconnecting the return hose. Secondly remove the PS vane pump assembly through bolt removal of its two assembly set bolts. Begin with PS vane pump assembly installation through two bolts using a torque value of 39 Nm (400 kgf-cm, 29 ft. lbs.). Begin by attaching the return hose and then connect the pressure feed tube while installing new gaskets on both tube sides along with installing the union bolt. Perform torque adjustments to 47 Nm (475 kgf-cm, 34 ft. lbs.) after verifying that the tube stopper touches the PS pump body. Finish the installation with drive belt tightening using the belt adjusting bolt first before torquing the power steering idle pulley set nut to 39 Nm (400 kgf-cm, 29 ft. lbs.) while performing power steering system bleeding.
