Detailed Product Description

This Cardone power steering pump (part number 21-5459) features an aluminum housing that provides strength while helping dissipate heat generated during operation.

The pump includes a sealing kit and instruction sheet to assist with installation. It does not come with mounting hardware or a reservoir cap, and it is not equipped with a remote reservoir or reservoir itself.
