Product Description
The CARDONE 21-5371 Remanufactured Power Steering Pump is engineered to meet or exceed original equipment performance standards. CARDONE evaluates every OE pump design for improvement opportunities and incorporates upgrades to enhance durability, reliability, and long-term performance.
Each unit features triple-tested internal components—including cam packs and spool valves—to ensure consistent operation. Premium HNBR seals resist high-temperature breakdown, preventing leaks and extending service life. Precision-machined shafts eliminate premature seal wear, while fully calibrated pressure relief valves ensure proper hydraulic regulation.
Before leaving the facility, every pump undergoes computerized testing to verify pressure output, bypass control, fluid flow, steering effort, and noise levels. CARDONE’s eco-conscious remanufacturing process reduces material consumption by up to 80% compared to new production.
