Built for OE-Style Return Line Service

This Sunsong power steering return line hose assembly is made for the steering return circuit, where fluid moves back to the reservoir under lower pressure but can still see elevated temperatures and exposure to road contaminants. The 3404372 uses steel tubing with a zinc coating to help resist humidity, road salt, water, and grime. It is a direct-fit replacement for 1997-2001 Lexus ES300, 1997-2001 Toyota Camry, and 1999-2000 Toyota Solara, including pipe-to-reservoir routing. This part cross-references Four Seasons 55502 for the same application.
