Product Description
The CARDONE 20-55994 Remanufactured Power Steering Pump delivers reliable, OEM-grade steering performance for 2006–2008 Buick Lucerne 3.8L models. Each unit is meticulously remanufactured to meet or exceed original equipment specifications, ensuring consistent steering assist, quiet operation, and long-term dependability.
Every pump undergoes comprehensive hydraulic efficiency testing to verify performance in flow, pressure, and bypass regulation. CARDONE’s triple-testing process of critical components—such as spool valves, cam packs, and shafts—ensures smooth steering response and durability under demanding conditions.
Constructed using premium HNBR seals and 100% new O-rings, this pump resists heat degradation and fluid breakdown. Precision-machined shafts prevent seal wear, while calibrated pressure relief valves maintain consistent steering feel. Each unit includes an integrated reservoir, providing a direct-fit replacement ready for installation.
As part of CARDONE’s eco-friendly remanufacturing process, this pump helps conserve up to 80% of raw materials and energy, combining sustainability with superior performance.
