Mobile Power Steering Pump Replacement at Home or Office

If your vehicle's power steering feature unexpectedly stops working, it might be because of steering pump failure. Your vehicle's power steering pump may be causing a loss or decrease in hydraulic pressure. Your power steering system makes it easy to control your car's direction when you turn the steering wheel, and the power steering pump is a key component to make it work. The power steering pump circulates fluid throughout the system, but can fail due to internal problems, fluid leaks, or bearing and pulley issues. If the power steering pump develops a leak or loses its ability to circulate fluid properly, it will need to be replaced.

What is Power Steering Pump Replacement?

The reason your cars steering turns so easily is due to the power steering pump. High-pressure fluid circulates through the steering system, adding assist at the power steering gear to reduce the effort of your steering input. The high-pressure fluid originates from the power steering pump. The power steering pump is driven by a belt on your engine, typically a serpentine belt. The rotational force from the belt spins a shaft which turns a rotor in the pump housing that draws fluid in from the fluid reservoir. In the power steering pump, excessive wear can occur when the fluid is contaminated or gritty, or if the pump runs out of fluid.

How is Power Steering Pump Replacement Done?

  1. Shut off the engine and let it cool off.
  2. Locate and identify the power steering pump.
  3. Remove the power-steering belt from the pump.
  4. Place a pan under the pump and drain the power-steering fluid from the pump by disconnecting the feed and return lines.
  5. Remove the mounting bolts from the mounting bracket.
  6. Remove the power steering pump.
  7. Install the new power steering pump and bolt it down to the mounting bracket.
  8. Reconnect the feed and return lines to the pump.
  9. Reconnect the power steering belt, making sure it's tight.
  10. Fill the new pump with power steering fluid.
  11. Turn on the engine and let it run for a few minutes before you drive it, to allow the fluid to circulate in the new pump.
  12. Check the fluid level in the pump (using the dipstick) and make sure there is enough fluid.
  13. Turn the steering wheel to the right and left and see if it moves easily.


The complete power steering system should be flushed and new fluid used when power steering pump replacement is performed. Always use the correct fluid for your car's power steering, according to manufacturer's specs.
