• Q: How to service and repair the vane power steering pump on 2006 Toyota Solara?

  A: The first step to maintain the 2AZ-FE vane power steering pump requires wheel removal from the front right position followed by power steering fluid draining. The first step involves removing the front fender apron seal from the right side and disassembling the fan and generator V belt as well as completing the removal of clip securing hose No.1 to the oil reservoir. Avoid transferring fluid onto the V belt surfaces during the servicing process. The pressure feed tube assembly requires a 27 mm wrench to hold the pressure port union before removing the union bolt together with its gasket. Remove the vane pump assembly after disconnecting the oil pressure switch connector and applying Special Service Tool 09249-63010 with a 14 mm deep socket wrench to loosen bolt A (do not remove bolt A) and removing bolt B. Securing the vane pump assembly in a vise using Special Service Tool: 09630-00014 (09631-00132) enables one to remove the power steering suction port union with its O-ring followed by taking out the flow control valve and compression spring. Replace the damaged O-ring before removing it from the power steering oil pressure switch. The w/pulley shaft sub-assembly becomes accessible after removing the O-ring then the four bolts to separate the rear housing. Proceed by taking out ten vane pump plates together with the vane pump rotor from the pump and then remove the vane pump cam ring and front side plate including all O-rings. Take out the housing oil seal from its compartment while protecting the housing front from damage. Check the vane pump shaft and its bush inside the housing front for oil clearance while verifying proper measurements less than 0.07 mm (0.0028 inch). Measure the vane pump plates for thickness between 1.405 to 1.411 mm (0.05531 to 0.05555 inch) while also validating the vane pump rotor groove clearance against the vane plates up to 0.03 mm (0.0012 inch). Apply compressed air to verify that the flow control valve works well and also check for any leakage present. Verify the compression spring stands at least 36.9 mm (1.453 inch) in its free length. Check for union damage at the pressure port while examining the smooth operation of the pump during rotation without producing any noises. A temporary service bolt measuring 50 mm (1.97 inch) long and with characteristics of 10 mm (0.39 inch) diameter and 1.25 mm (0.0492 inch) pitch should be installed for pulley rotating torque evaluation. Acceptable torque values are below 0.27 Nm (2.8 kgf-cm, 2.4 ft. lbs.). Use Special Service Tool: 09950-60010 (09951-00280) and Special Service Tool: 09950-70010 (09951-07100) with a press to reassemble the new housing oil seal that has power steering fluid coating according to the correct orientation. The assembly of w/pulley shaft should be handled with care to prevent oil seal lip damage. Insert the front side plate with new O-rings pre-coated in power steering fluid and position the cam ring correctly and install the vane pump plates with the round end outward. Position the vane pump rotor and apply power steering fluid to all the vane pump plates before facing its round side outward. Place the w/pulley shaft sub-assembly into its slot while installing the rear housing by using a new O-ring in precise alignment before tightening it to 22 Nm (224 kgf-cm, 16 ft. lbs.). Start with installing the power steering oil pressure switch that incorporates a new O-ring then torque it to 21 Nm (214 kgf-cm, 16 ft. lbs.). Next, position the flow control valve and its components before torquing the pressure port union to 69 Nm (704 kgf-cm, 51 ft. lbs.) and the suction port union to 12 Nm (122 kgf-cm, 9 ft. lbs.). The last assembly step involves first tight bolt A temporarily before securing it with bolt B at 37 Nm (377 kgf-cm, 27 ft. lbs.) then torquing bolt A to 26 Nm (264 kgf-cm, 19 ft. lbs.) by using the special service tool. The oil pressure switch connector must be reestablished after which the pressure feed tube assembly with new gasket must be installed along with 52 Nm (525 kgf-cm, 38 ft. lbs.) torque on the union bolt. The technician must reinstall the oil reservoir to hose No.1 and insert the fan and generator V belt followed by attaching the front fender apron seal and front wheel while torquing the parts to 103 Nm (1,050 kgf-cm, 76 ft. lbs.). The final step involves bleeding power steering fluid while inspecting for leakages.
