Before purchasing and installing a power steering pump make sure it is the correct fit for your vehicle.

  • Check your vehicle's power steering fluid levels periodically and add fluid when necessary.
  • Replace O-rings when doing any steering system service, as re-using old O-rings can potentially cause leaks.
  • Regardless of the original color of new power steering fluid, all fluids will darken in color during use. Fluid color is not necessarily an indicator of fluid condition.
  • Always check the manufacturer's service information for the correct power steering fluid to use. Different fluids are specified by the manufacturer to meet the operating requirements of their power steering systems. Using the wrong fluid could cause hose and seal damage as well as fluid leaks.
  • After any service of the power steering system, always bleed the air from the system and verify proper system operation. An accurate fluid level cannot be obtained unless air is bled from the steering system. The air in the fluid may cause pump cavitation noise as well as pump damage over a period.
  • Flushing the system will help eliminate any residual contaminants from causing future power steering pump failure. Dirty or contaminated fluid may cause low or no pressure from the power steering pump.
  • Always follow the manufacturer's specific instructions on flushing.
  • If you live in areas that experience harsh winter weather, have the entire steering system inspected before winter arrives.
  • Regularly inspect power steering pump for signs of damage or wear and replace them if signs of damage are found.

Signs of wear for power steering pumps include but are not limited to:

  • Excessive noise from the pump
  • Nonexistent or inconsistent power assist when steering
  • Power steering components seizing up
  • Power steering system leaking
  • Reduced power steering fluid flow
  • Unusual noise when turning the steering wheel
  • Contamination of power steering fluid
  • A shimmy or shake in the steering wheel
  • Heavy or unresponsive steering at low speeds or during parking lot maneuvers
