Detailed Description

This Sunsong power steering return line hose assembly, part number 3404182, is engineered for the return side of the steering system where fluid is routed from the cooler back to the reservoir. It is built to exceed original equipment performance standards for low-pressure service and uses corrosion-resistant steel tubing with a zinc coating to help withstand humidity, road salt, water, and grime. For Cadillac STS and Cadillac SRX models in the listed years, 3404182 provides the correct cooler to reservoir configuration and OE-style fitment.

This part cross-references Dorman - HELP 80906 and Gates 352507 for the same application.

What This Part Helps Address

• Leaking or cracked power steering return hose sections
• Fluid seepage at the cooler-to-reservoir return path
• Corrosion on exposed steering hose tubing
• Restricted or deteriorated return-line routing
• Noise or steering performance issues caused by fluid loss

Installation Notes and Tips

Verify the vehicle year, model, and cooler to reservoir routing before installation. Inspect adjacent brackets, grommets, heat shields, bushings, and protective sleeves for wear and replace any damaged components as needed to restore proper hose routing and protection. Confirm all connections are clean and properly seated before refilling and bleeding the power steering system.
