Product Description
The CARDONE 20-66989 Remanufactured Power Steering Pump restores smooth, consistent steering performance for Chevrolet, GMC, and Isuzu midsize pickup applications. Each pump is remanufactured to meet or exceed OEM performance, combining precision engineering with proven durability for long service life.
All internal components—including cam packs, spool valves, and pressure-relief valves—are triple-tested to ensure leak-free reliability and quiet operation. Every pump is built with 100% new premium-grade HNBR seals and O-rings, which maintain flexibility and prevent breakdown under high heat and pressure.
Each assembly undergoes a complete hydraulic efficiency test measuring pressure, bypass, flow, steering effort, and noise performance. The result is a pump that performs and fits like new while using 80% less energy and raw materials compared to manufacturing a new unit.
