CARDONE Reman Power Steering Pump P/N:21-5466

Restore smooth, effort-saving power assist with the CARDONE Remanufactured Power Steering Pump 21-5466. This hydraulic pump pressurizes the power steering fluid that helps turn the wheels, and it drops in as a direct-fit replacement for the 2005-2011 Cadillac STS (see the Buyer's Guide tab for engine-level applications). If a worn or leaking original pump is behind your whining, groaning, or hard steering, this remanufactured unit replaces it.

• Engineered to meet or exceed O.E. performance: original designs are scrutinized and, where applicable, upgraded for a more durable part; every unit undergoes a hydraulic efficiency test.
• Triple-tested critical components: campacs, spool valves, and other key parts are triple-tested for reliability.
• 100% new O-rings and premium-grade HNBR seals: HNBR resists breakdown at high temperatures, unlike conventional seal material, to help prevent leaks.
• Precisely surfaced shafts: machined to spec to reduce premature seal wear and extend pump life; supplied with a 100% tested and calibrated pressure relief valve.

Final assembly is computer-tested for pressure, bypass, fluid flow, valve operation, steering effort, and noise. The remanufacturing process is earth-friendly, cutting the energy and raw material of a new part by roughly 80%.
