Built for Return-Side Steering Service

This Sunsong power steering return line hose assembly is made to replace worn or leaking return hoses on Volkswagen Golf and Volkswagen Jetta models from 1985 through 1992. Part number 3402188 is designed around the original routing and connection points, helping restore proper fluid return from the steering system reservoir and reducing the risk of seepage at aged hose connections. The steel tubing is zinc-coated to better withstand humidity, road salt, water, and grime in everyday driving conditions.

This part cross-references Gates 358810 and Dayco 80170 for the same application.

Common Problems This Hose Can Address

• Power steering fluid seepage from an aged return line
• Cracked or hardened hose material from heat and age
• Corrosion on exposed steering line tubing
• Improper hose fit after previous repairs
• Steering system contamination from deteriorating hose material

Installation Notes and Tips

Verify the end connections before installation: 3/8 in. ID hose on one end and a 16 mm male O-ring fitting on the other. Confirm the hose length and routing match the vehicle before removal of the original line. Because this is a return line assembly, clean the surrounding area before disconnecting the old hose to help prevent debris from entering the steering system. Use the vehicle’s specified fluid and inspect adjacent seals, clamps, and fittings during service.

Sunsong manufactures this return hose assembly to exceed original equipment performance standards for low-pressure, high-temperature return applications.
