CARDONE Reman Power Steering Pump P/N:21-5257

Push the hydraulic pressure your steering system needs with the CARDONE Remanufactured Power Steering Pump 21-5257 (also written 215257). This engine-belt-driven pump pressurizes the power steering fluid that provides hydraulic assist to the steering gear, and it installs as a direct-fit replacement for the 2000-2005 Hyundai Sonata, 2001-2006 Kia Magentis, and 2001-2006 Kia Optima — see the Buyer's Guide tab for engine-level fitment.

• Built to O.E. performance: original designs are scrutinized and, where applicable, upgraded for a more durable part; all critical components are tested and every unit passes a hydraulic efficiency test.
• Triple-tested internals: critical components such as campacs and spool valves are triple-tested for reliability, and units ship with 100% tested and calibrated pressure relief valves.
• HNBR sealing: assembled with 100% new O-rings and premium-grade HNBR seals that resist breaking down at high temperatures, unlike conventional seal material.
• Precision shafts: shafts are surfaced to precise specifications to reduce premature seal wear and extend pump life.

Final pump assembly is computer-tested for pressure, bypass, fluid flow, valve operation, steering effort and noise. Whining or groaning while turning, heavy or stiff steering, and fluid weeping around the pump are common signs a power steering pump may need replacing; if a failing pump is the cause, this unit replaces it. The remanufacturing process reduces the energy and raw material of building new by 80%.
