- Complete kit: ships with a new pump, pulley, return pipe adapter, o-ring, and reservoir.
- 100% tested: each unit is hydraulically tested under load in the USA to confirm OE operation and fitment.
- OE-quality build: manufactured with OE-quality components and held to strict industry standards.
- No core charge: AAE New P/S pumps are sold without a core charge.
The pump is the belt-driven heart of the hydraulic steering system, generating the fluid pressure that provides steering assist. If a worn or failing original pump is behind heavy steering effort, whining, or fluid leaks, this kit replaces it. AAE recommends replacing the fluid reservoir when replacing the pump, since a clogged reservoir can starve the new pump. Flush and fill the system with an OE-approved power steering fluid.
