Application Details

This Sunsong power steering return hose, part number 3602686, is made for the Cadillac Catera return path from the steering gear to the cooler.

This part cross-references Dayco 80316 and Gates 352670 for the same application.

Common Problems It Can Address

• Leaking return hose connections at the steering gear or cooler
• Cracked, hardened, or swollen hose material
• Corrosion on steel tubing from moisture and road exposure
• Restricted fluid return caused by aged hose internals
• Noise or steering performance issues related to fluid loss

Installation Notes

Verify the end fittings, length, and routing before installation. This assembly uses a 3/8 in. ID hose end and a 16 mm male O-ring end, so matching the original connection points on the Cadillac Catera is important. Inspect adjacent clamps, seals, and cooler connections for wear before completing the repair.

Quality Assurance

Sunsong manufactures this return hose assembly to exceed original equipment performance standards for return-side steering service. The steel tubing is zinc plated to improve resistance against corrosion and rust in demanding underbody conditions.
