Product Line Details: Cardone Power Steering Pump

The Cardone Power Steering Pump line focuses on remanufactured components that meet or exceed OEM specifications. This product line emphasizes quality restoration of hydraulic power steering systems, providing reliable performance and fitment for specific vehicle applications. The 21-188 pump is part of this line, offering a balance of durability and precision engineered to Subaru's steering requirements.

Detailed Product Description

This power steering pump features an aluminum housing that ensures corrosion resistance and structural integrity under demanding conditions. The pump uses a hose barb inlet and a threaded outlet (14x1.5 thread size) with an O-ring seal to prevent leaks. The included pulley is press-on type, designed for easy installation and secure attachment. While the pump supports a remote reservoir setup, the reservoir itself is not included. Mounting hardware is not provided, so reusing existing hardware is necessary. The package contains the hydraulic pump, a sealing kit, and an instruction sheet to assist with installation.
