Detailed Application and Fitment

This Sunsong power steering return line hose assembly 3401853 is made for the 1997 Ford F-150, gear to cooler routing. It is a direct-fit replacement for the return side of the steering system, where fluid moves under lower pressure but can still see elevated temperatures and constant exposure to road contaminants. The steel tubing is zinc plated to resist rust from humidity, road salt, water, and grime, while the hose assembly is built to match the original routing and connection style.

This part cross-references Gates 352010 and Dorman HELP 80253 for the same application.

What This Hose Helps Address

• Power steering fluid seepage at the return line
• Corrosion on the original steel tubing
• Cracked or hardened hose material from heat and age
• Restricted steering fluid return flow caused by damaged lines
• Noise or steering effort changes related to a failing return hose

Installation Notes and Tips

Verify the gear-to-cooler routing on the 1997 Ford F-150 before installation and compare the end fittings, length, and hose path to the original assembly. The return line uses a 3/8 in ID hose end and a 16 mm male O-ring end, so matching the connection style is important for proper sealing and routing. Inspect nearby brackets, sleeves, and grommets on the vehicle and replace any worn components as needed to maintain the original hose path.

Quality Assurance

Sunsong manufactures this return hose assembly to exceed original equipment performance standards for return-side steering service. The design uses high-grade steel tubing with zinc coating for added resistance to corrosion and rust, supporting long-term durability in demanding underbody conditions.
