Detailed Product Description and Specifications

The Sunsong 3401612 power steering pressure line hose assembly is engineered with a 60.9-inch (1546 mm) length to fit the hydraulic routing requirements of select Cadillac models. Both ends feature male o-ring fittings, with the first end sized at 16 mm and the second at 18 mm, ensuring secure and leak-resistant connections. The hose is constructed from chlorosulfonated polyethylene (CSM), a material known for its resistance to heat, oil, and abrasion, which is critical for maintaining integrity under power steering system pressures.

This assembly includes a power steering (PS) switch port, allowing integration with the vehicle’s steering pressure sensor system. The absence of a bracket simplifies installation in the designated routing paths of the Cadillac Allante, DeVille, Eldorado, and Seville models. The part number 3401612 corresponds to this specific configuration, ensuring compatibility and performance.
