Detailed Fitment and Construction

This Sunsong 3404845 hose assembly is made for the return side of the power steering system, where fluid moves back from the gear under lower pressure but elevated temperature. The steel tubing is zinc coated to help resist road salt, moisture, grime, and humidity, while the hose construction supports reliable service in the steering return circuit. It is a direct-fit option for 2008-2012 Chevrolet Malibu, from gear, includes cooler tube; 2007-2009 Pontiac G6, from gear, includes cooler tube; and 2007-2009 Saturn Aura, from gear, includes cooler tube. This part cross-references Dayco 85017 and Gates 365939 for the same application. Part number 3404845 is a practical replacement when restoring the steering return path on these vehicles.

Common Problems This Part Can Address

• Leaking or cracked power steering return hose
• Corrosion on the original steel line
• Fluid seepage at the return-side connection points
• Restricted or damaged hose routing from age and heat exposure
• Noise or steering performance issues caused by a compromised return line

Installation Notes and Tips

Verify the vehicles year, make, model, and return-line routing before installation. Confirm the 3/8 in. bubble flare connection and the from-gear configuration with cooler tube included in the application. Inspect adjacent steering components, hose clips, and mounting points for wear before transferring the new assembly into place. Part number 3404845 should be matched to the listed fitment only.

Quality Assurance

Sunsong manufactures this return hose assembly to exceed original equipment performance standards for return-side steering service.
