Installation Notes
Before installing this Cadillac STS power steering pump, flush the steering system and refill it with an OE-approved power steering fluid. AAE also recommends replacing the steering fluid reservoir when servicing the pump, since a restricted reservoir can starve the replacement unit. Verify vehicle application and inspect related steering components before installation.
