Detailed Description

This Sunsong power steering pressure line hose assembly is built to replace the pressure side hose in select Buick Skylark, Oldsmobile Achieva, and Pontiac Grand Am models from 1992-1993. The hose uses male O-ring fittings at both ends, with 16 mm and 18 mm connection sizes, and measures 35.5 inches in length for a direct-fit replacement where specified by the application. Sunsong 3403027 is manufactured with high-grade steel tubing and zinc coating to resist rust, road salt, moisture, and grime, while the CSM hose material supports long-term fluid handling performance.

This part cross-references Gates 360480 and Dayco 71793 for the same application.

Common Steering Issues This Part May Address

• Power steering fluid leaks from a worn or damaged pressure hose
• Hard steering caused by pressure loss in the hydraulic line
• Noise or hesitation during steering input from restricted fluid flow
• Corrosion-related hose deterioration in high-humidity or salt-exposed environments
• Poor sealing at the hose connection points

Installation Notes and Tips

Confirm end fitting sizes and hose routing before installation.
