Sunsong 3405028 Power Steering Return Line Hose Assembly - Cooler To Reservoir

Power Steering Return Hose Overview

This Sunsong power steering return line hose assembly is built for low-pressure, high-temperature return flow and direct-fit service. It is engineered for the 2005-2008 Honda Pilot, cooler to reservoir, with fitment-specific construction that follows the original routing and connection style.

Key Features

• CSM hose material for durable fluid handling in steering return service.
• Designed for low-pressure operation with a 250 psi maximum working pressure.
• 9.6 mm ID hose fittings at both ends for matched connection sizing.
• Precision-engineered replacement for exact fit and original-style restoration.
• Corrosion-resistant steel tubing with zinc plating for added protection against rust and road exposure.

Detailed Description

Part number 3405028 is a Sunsong power steering return line hose assembly made for the 2005-2008 Honda Pilot, cooler to reservoir. It is intended for return-side steering fluid transfer where heat, moisture, and contamination resistance matter. The hose assembly uses CSM material and is paired with steel tubing that is zinc coated to help resist corrosion from humidity, water, grime, and road salt. Part number 3405028 is also engineered to restore the original fit and function of the return line path on the Honda Pilot.

This part cross-references Monroe Shocks & Struts (e.g., 53733S9VA02) and Rein (e.g., PSH0590) for the same application.

What It Is Used For

• Leaking or deteriorated power steering return hose sections.
• Restricted fluid return caused by age, heat, or contamination.
• Corrosion-related hose or tube damage in the steering return circuit.
• Improper fit or routing after prior repair work.

Installation Notes and Tips

Verify the cooler-to-reservoir routing before installation and compare the end fitting sizes to the removed part. Inspect nearby brackets, grommets, heat shields, bushings, and sleeves during service so the replacement follows the original path and support points. Confirm the hose is seated correctly at both ID hose connections before refilling and bleeding the steering system.

Quality Assurance

Sunsong return hoses are manufactured to exceed original equipment performance standards for return-side steering service. The zinc-coated steel tubing adds corrosion resistance for harsh underbody conditions, and the assembly is precision engineered for exact fit on the listed application.
