How to remove and install the power steering pump on Lexus RX330?

The first step to work while handling the power steering pump is to unhook the cable of the negative terminal of the battery. Turn the steering wheel back and forth in its fullest extent several times to evacuate maximum fluid that can be siphoned from the power steering fluid reservoir with the help of a large syringe or suction gun; prepare a drain pan for the fluid spill while disconnecting the fluid hoses. Turn the right front wheel lug nuts on the counterclockwise direction, lift the vehicle, and place it on jackstands, then remove the right front wheel. If needed remove the right front fender apron seal and the liner on the right front. Next, remove the drivebelt. Remove the fluid feed hose from the pump and unscrew the electrical connector of the power steering pressure switch. Loosen the pressure line to pump union bolt and dis-connect the pressure line from the pump with the help of two spanners and make sure that you change all the sealing washers if required. After that, the mounting bolts will have to be unscrewed for the removal of the pump, although the upper bolt is partially disguised but will let go when the pump is removed. In regard to installation, it is recommended to reverse the process of removal when tightening the union bolt of pressure line, and mounting bolts to the recommended torque and adjusting the tension of the drivebelt. Last, replenish the amount of the fluid in the reservoir to the required level, and evacuate the system.

Lexus RX330 Power Steering Pump

The Lexus RX330 Power Steering Pump allows drivers to turn the wheel with minimal exertion as it converts engine power into hydraulic pressure. Mounted on the engine and spun by a belt, the pump draws fluid from an attached or remote reservoir, then proceeds to pump pressurized fluid through a high-pressure hose to the steering gear control valve, where it moves a piston that adds muscle to every turn. When the wheel remains in the center, equal pressure keeps the piston in a fixed position, but the second the driver turns, the valve redirects flow to one side and help arrives instantly. Over the years, the Lexus RX330 applied two styles of Power Steering Pump; they are hydraulic units with a built-in reservoir and one fed by a separate tank, the difference being mainly in fluid storage and return hose routing. Some later models of the Lexus RX330 added an electronic flow control feature, whereby the output from the Power Steering Pump would vary according to the speed of the vehicle so that in parking lots the vehicle would have generous assistance, but on the highway it would have a stiffer feel. Warning signs are whining, belt squeal, leaks, or heavy steering, all of which point toward checking or replacing the Power Steering Pump before assist is gone. Regular checks keep the Lexus RX330 Power Steering Pump healthy and steering effortless.
