  Q: How to remove and install a power steering pump on Lexus ES350?

  A: Disconnect the cable from the negative battery terminal. Using a large syringe or suction gun, siphon as much fluid out of the power steering fluid reservoir as possible. Place a drain pan under the vehicle to catch any fluid that spills out when the hoses are disconnected. Loosen the right front wheel lug nuts. Raise the vehicle and support it securely on jackstands. Remove the right front wheel. Remove the right front fender apron seal by removing the three screws and the plastic inner seal from the fender well. Remove the drive belt. Detach the fluid feed hose from the pump. Remove the banjo bold and the feed line fitting bolt. Disconnect the electrical connector from the Power Steering Pressure Switch. Remove the pressure line-to-pump union bolt and separate the line from the pump. Use two wrenches, one to hold the pressure port fitting and one to hold the union bolt. Remove the sealing washers on each side of the fitting - these should be replaced when installing the pump. Working through the power steering pulley, loosen the pump mounting bolts completely. Turn the pulley until an opening is over the upper bolt for access. Lower the pump and remove the mounting bolts, then remove the pump. Installation is the reverse of removal. Be sure to tighten the pressure line banjo bolt and the feed line fitting bolt. Adjust the drive belt tension. Top up the fluid level in the reservoir and bleed the system.
