Detailed Description

This Sunsong power steering return line hose assembly, part number 3403749, is made for Kia Rio applications from 2003 through 2005. It is built for the return side of the steering system, where fluid moves back under low pressure but can still see elevated temperatures and constant exposure to road contaminants. The steel tubing is zinc plated to help resist rust from humidity, road salt, water, and grime, while the hose construction supports dependable routing and sealing at the specified connection points. This part cross-references Honda-style OE application 57770FD092 for the same application.

Common Problems This Part Can Address

• Power steering fluid seepage at the return line
• Corrosion or rust on the original hose assembly
• Cracked, hardened, or deteriorated hose material
• Improper routing or fit from a worn steering return line
• Noise or steering performance issues caused by fluid loss

Installation Notes and Tips

Verify the end fittings before installation: 16 mm male O-ring on one end and 1/2 in beaded tube on the other. Confirm the hose length and routing match the original layout on the 2003-2005 Kia Rio, from gear, and inspect nearby brackets, bushings, and heat protection points for wear before final assembly. Clean the connection surfaces and check the system for leaks after installation.

Quality Assurance

Sunsong manufactures this return hose assembly to exceed original equipment performance standards for return-side steering service. The design uses corrosion-resistant materials and exact-fit engineering to restore the original hose path and connection geometry on the Kia Rio.
