Product Details and Specifications
This power steering pump features an aluminum housing that ensures strength and efficient heat management during operation. The pump uses a press-on pulley attachment, though the pulley itself is not included, allowing for reuse of the original pulley if it remains in good condition. The inlet connection is a hose barb type, while the outlet is threaded with a 16x1.5 size, designed for secure and leak-free hose attachment using O-ring seals. The pump supports remote reservoir setups, but the reservoir cap and reservoir are not included in the package. The package contents include the hydraulic pump, an instruction sheet for installation guidance, and a sealing kit to ensure proper sealing of connections.

Installation Notes and Tips
When installing the Cardone 21-5310 power steering pump, ensure the original pulley is inspected for cracks or damage, as the pulley is not included with this pump. Use the provided sealing kit to prevent leaks at hose connections. Confirm that the hose port type matches your vehicle’s system (O-ring type) and that the inlet and outlet attachment types correspond to your existing hoses. Bleed the power steering system properly after installation to avoid air pockets and ensure smooth steering operation.
