Detailed Product Description
The Sunsong 3401587 power steering pressure line hose assembly is specifically designed to meet the hydraulic requirements of various GM vehicles, including Buick Century, Chevrolet Malibu, Oldsmobile Cutlass, and Pontiac Grand Prix models. The hose is made from CSM (chlorosulfonated polyethylene) material, known for its resistance to heat, oil, and abrasion, which helps maintain system integrity under demanding conditions.
This assembly features male inverted flare fittings on both ends—11/16 inch on one end and 5/8 inch on the other—ensuring a tight, leak-resistant seal with compatible power steering components. The hose length of 35.8 inches (909 mm) provides the correct routing and fitment for the specified vehicle applications. Notably, this part does not include a bracket or a power steering switch port, which simplifies installation in systems that do not require these features.
