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.
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%.
