Detailed Product Overview

This Sunsong power steering return line hose assembly 3404233 is built to restore the return path between the power steering cooler and reservoir on Ford Edge and Lincoln MKX vehicles. The assembly is made for low-pressure return service and uses steel tubing with a zinc coating to resist rust and corrosion from humidity, road salt, water, and grime. The 3/8 in. ID hose ends and 34 in. overall length support a direct-fit replacement for the specified applications.

This part cross-references Dorman OE Solutions 979-2552 for the same application.

Common Problems This Part Addresses

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

Installation Notes and Tips

Verify the cooler-to-reservoir routing before installation and compare the original line length, end style, and mounting points to the replacement assembly. This hose assembly is intended for the return side of the system, not the high-pressure feed line. Inspect adjacent brackets, grommets, heat shields, bushings, and protective sleeves on the vehicle and replace worn components as needed to restore the original routing and protection.
