Detailed Description

This Sunsong power steering return line hose assembly is made to match the original routing and connection style used on select Toyota Sienna models. It is designed around the return side of the steering system, where fluid moves back from the gear to the reservoir under lower pressure than the pressure line. The 34-inch hose assembly combines a 3/8-inch beaded tube fitting on one end with a 17 mm male O-ring fitting on the other for the specified application.

Built with high-grade steel tubing and zinc-coated protection, Sunsong 3402509 helps resist corrosion in harsh underbody conditions. This part cross-references Gates 352186 and Hayden 5050 for the same application. It is a practical replacement choice for Toyota Sienna owners looking for a direct-fit power steering return hose assembly.

Common Problems This Part Can Address

• Power steering fluid seepage at the return hose connection
• Cracked or hardened hose material from heat and age
• Corrosion on the original steel tubing
• Improper steering fluid return flow caused by a damaged hose assembly
• Noisy steering operation related to a worn return line
