Built For Return-Line Service

This Sunsong power steering reservoir hose, part number 3402466, is made for the return side of the steering system where fluid moves at low pressure but can see elevated temperatures. The hose uses 5/8-inch inside diameter fittings at both ends and a 24-inch overall length, making it a practical replacement for molded reservoir hose applications on BMW 3 Series, 5 Series, Z3, X3, and X5 models. Sunsong specifies this hose for exact-fit replacement use, and the design supports restoration of the original hose path on the vehicle.

This part cross-references Dayco 80633 and Gates 352199 for the same application.

Installation Notes

Verify hose routing, end size, and molded application details before installation. This hose uses ID hose connections at both ends and is intended for return-line service, not high-pressure pump output. Inspect adjoining clamps, reservoir necks, and nearby steering components for wear before completing the repair. Confirm the vehicle-specific notes, including production-date callouts such as From 9/1 and From 4/1 where listed.

Quality Assurance

Sunsong builds this hose to exceed original equipment performance standards for return-hose service. The tubing is manufactured from high-grade steel with a zinc electroplated finish for added resistance to corrosion and rust from humidity, road salt, water, and grime. Part number 3402466 is engineered as an exact-fit replacement for the listed BMW applications.
