  • Suitable for low-pressure, high-temperature operation

Detailed Description

This Sunsong power steering return line hose assembly, part number 3404370, is made for the return circuit on the Honda Odyssey power steering system. It is engineered to OE dimensions for the 2005-2010 Honda Odyssey cooler tube application, helping maintain proper fluid return while withstanding heat, moisture, road salt, water, and grime exposure. This part cross-references Dayco 85049 for the same application.

Built with high-grade steel tubing and a zinc-coated finish, 3404370 is intended to replace worn or corroded return line hardware with a direct-fit assembly that follows the original routing and mounting points. The result is a cleaner repair for Honda Odyssey steering service where the return line has deteriorated or leaked.

What It Helps Fix

  • Power steering fluid seepage from a damaged return hose
  • Corrosion on the cooler tube or attached steel line
  • Noise or poor steering feel caused by restricted fluid return
  • Heat-related hose deterioration in the steering return circuit
  • Fitment issues from bent, rusted, or worn original tubing

Installation Notes and Tips

Fits 2005-2010 Honda Odyssey, cooler tube. Confirm the routing, mounting points, and connection style against the original line before installation. Inspect adjacent steering components, clamps, and seals for wear so the repair addresses the full return-side condition. Part number 3404370 should be matched to the vehicle’s cooler tube configuration during service.

Quality Assurance

Sunsong manufactures this return hose assembly to exceed original equipment performance standards for return-line service. The zinc-plated steel construction is specified to improve resistance to corrosion and rust in harsh underbody conditions.
