Detailed Description

This Sunsong power steering reservoir hose, part number 3401849, is built to replace worn or leaking return lines in GM full-size van and G-series steering systems. It is designed for the low-pressure return side of the power steering circuit and is suitable for high-temperature operation. The hose construction uses CPE material, while the tubing is made from high-grade steel with a zinc coating to help resist humidity, road salt, water, and grime. This part cross-references Dayco 80168 and Gates 360630 for the same application.

Installation Notes and Tips

Verify hose routing, end size, and length before installation. This hose uses 5/8 in. ID hose connections at both ends and does not include a bracket or PS switch port. Inspect adjacent steering components, clamps, and mounting points for wear before completing the repair. Confirm the vehicle application against the listed GM van and G-series fitment before ordering.
