ATSCO pumps experience 100% performance testing to ensure proper pressure, flow and leak proof operation. All hard parts are stringently inspected, polished, resurfaced, or replaced if they do not meet specifications. ATSCO power steering pumps are remanufactured to ensure factory performance.


  • Bushings & bearings are inspected and replaced when necessary
  • Internal components are inspected for wear and replaced with new when necessary
  • Input shafts are measured, centerless ground, and replaced if not to OE tolerances
  • New OE quality seals and O-rings packs provide a leak-proof installation
  • Campack rings are resurfaced or replaced if necessary
Installation Tips
  • Replace Power Steering Pressure and Return Hoses when replacing the power steering pump. Steering hoses can degrade internally and cause contamination in the power steering system, which can damage the new power steering pump
  • Where applicable, replace the Power Steering Reservoir or clean the internal filter
  • Completely flush the system with an OE approved Power Steering Fluid prior to installation (the correct type of fluid is noted on the reservoir cap or in your owner's manual). Flushing the system is critical to prevent system contamination and failure
  • Consider replacing the Belt (found in the Belt Drive category). Modern belts wear gradually and become less efficient, which can put strain on the Power Steering Pump and other belt driven components
  • Install the pump and all supplied o-ring seals according to installation instructions, to prevent leaking
  • Consider installing a Power Steering Filter on the Power Steering Return Hose to prevent system contamination and extend the life of the power steering components
  • A replacement Power Steering Pump can whine or make noise until air is purged from the fluid. Bleed the system during installation to prevent noise and extend the life of the steering components
