Atlantic Automotive Engineering Power Steering Reservoir P/N:RES-0112
$108.99

Keep your power steering system quiet and properly fed with the Atlantic Automotive Engineering (AAE) Power Steering Reservoir RES-0112. This new hydraulic steering fluid reservoir drops in as a direct replacement for the OEM unit on the 2001-2007 Toyota Highlander, holding and supplying fluid to the pump. See the Buyer's Guide tab for engine-level fitment details.

  • Direct replacement: fits and functions like the original equipment reservoir.
  • Complete assembly: includes the reservoir and reservoir cap.
  • Protects new components: AAE recommends replacing the reservoir whenever a failed steering pump or rack is serviced, so old debris can't damage the replacement parts.
  • Restores a sealed supply: a cracked or damaged reservoir can let air into the hydraulic system, causing noise and premature steering component wear, or restrict fluid flow.

Signs this part may need replacing include cracks or damage to the reservoir body, fluid seepage, or air/noise in the steering system. When you replace a pump or rack, the power steering system should be flushed and the reservoir replaced to keep the new components clean. Always diagnose the cause of a steering complaint before ordering, since these symptoms can have other sources.
