Product Details and Specifications

This remanufactured power steering pump features an aluminum housing for strength and heat dissipation. It uses a press-on pulley attachment type, though the pulley itself is not included, so reuse of the original pulley is necessary. The pump has a single power steering outlet with a 16x1.5 thread size and a threaded outlet attachment type. The inlet connection is a hose barb with a seat-type hose port, designed to fit the original hydraulic lines. This pump is intended for vehicles equipped with a remote reservoir system; however, the reservoir and reservoir cap are not included in the package. The package contents include the hydraulic pump, an instruction sheet, and a sealing kit to assist with installation.

Common Applications and Problem Resolution

• Restores power steering assist in Buick Allure, LaCrosse, and Cadillac XTS models
• Addresses whining noises caused by worn or failing pumps
• Eliminates hard steering or inconsistent assist at low engine RPM
• Resolves leaks or pressure loss due to pump seal failure
• Corrects issues related to input shaft wear or flow control valve blockages

Installation Notes and Tips

When installing the Cardone 21-4063 power steering pump, ensure the original pulley is reused or replaced separately, as it is not included. Verify that the hose connections match the seat-type port and hose barb inlet attachment. Use the included sealing kit to prevent leaks and follow the instruction sheet carefully. It is recommended to inspect and, if necessary, replace power steering fluid during installation to maintain system performance. Proper bleeding of the power steering system after installation will help avoid air pockets and ensure smooth operation.
