Product Description
The CARDONE 20-57888 Remanufactured Power Steering Pump restores smooth, reliable steering performance to a wide range of GM 3.1L and 3.4L applications (1995–2003). Each unit is precisely engineered and remanufactured to meet or exceed OEM standards, providing dependable hydraulic pressure, quiet operation, and long service life.
Every CARDONE remanufactured pump undergoes extensive hydraulic and efficiency testing, verifying pressure, bypass, and flow consistency. Triple testing of critical components—such as spool valves, shafts, and cam packs—ensures performance reliability and eliminates steering noise or leaks.
Built with 100% new O-rings and premium-grade HNBR seals, this pump offers superior resistance to high temperatures and fluid breakdown. Precision-machined shafts eliminate premature wear, and all units include calibrated pressure relief valves for consistent steering effort.
As an environmentally responsible remanufactured part, the 20-57888 helps reduce waste and conserve up to 80% of energy and raw materials compared to new production, delivering value, quality, and sustainability in one product.
