How to remove and install the power steering pump on Toyota Highlander?

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.

Toyota Highlander Power Steering Pump

The Power Steering Pump converts engine rotation into hydraulic pressure to reduce steering effort by assisting the steering gear. The Power Steering Pump is the single part in your Toyota Highlander system that creates and maintains this pressure. The engine is where the Power Steering Pump is mounted. It is belt driven, which means that it gets the rotational movement from the car engine. The Power Steering Pump draws fluid from a reservoir. It pushes fluid through a high-pressure hose to the control valve. Turning the steering wheel causes the valve to send hydraulic pressure to one side of the piston located in the hydraulic cylinder. This causes a force to be generated on the linkage that moves the wheels. In case the steering wheel is centered, the pressure will be the same on either side of the piston and will maintain the vehicle straight on the road. A low-pressure return hose delivers fluid to the Power Steering Pump on the Toyota Highlander. Belt tension or fluid level problems can cause noise and affect driver assist. Usually, a leak, loose belt, or worn part will bring about a whining or squealing noise, while a worn pump and other issues can cause a reduction in driver assist. A Power Steering Pump sealed up perfectly helps ensure no fluid is lost, retaining normal steering feel and assisting the Toyota Highlander to steer with minimal effort.
