How to bleed a power steering pump

Updated February 21, 2017

Your automobile's power steering works under hydraulic pressure, allowing the steering wheel to be turned with a finger. For the system to perform at its optimum level, all air must be removed from it. If the steering becomes difficult to operate, or begins making squealing sounds, the system needs attention. First check the pump's reservoir to determine if the fluid is up to the proper level. If the fluid level is OK, you will need to bleed the power steering pump and lines.

Lift one of the vehicle's front wheel's off the ground with the jack and set it down on one of the jack stands. Repeat for other side.

Place the bottle cap on the ground and carefully punch a hole in the top with the Phillips screwdriver.

Slip one end of the PVC tubing over the power steering pump's bleeder valve. Place the other end of the tubing into the bottle, through the hole in the bottle cap.

Start the car and turn the wheel back and forth, all the way to one side and then the other, two times each.

Loosen the bleeder valve half a turn and place the bottle where you will be able to see it. Continue to turn the steering wheel back and forth until the fluid is running freely into the bottle, with no air pockets or bubbles. Close the bleeder valve.

Remove the vehicle from the jack stands and refill the power steering reservoir.
