Product Details and Specifications
This power steering pump features a hose barb inlet attachment and a single threaded outlet with a 16x1.5 thread size, ensuring compatibility with the original steering system plumbing.

Installation Notes and Tips
When installing the Cardone 21-494 power steering pump, ensure the pulley from the original pump is reused, as this unit does not include a pulley.
