Detailed Description

This Sunsong power steering pressure line hose assembly is built for direct replacement service on 1979 Buick Riviera, 1979 Oldsmobile Toronado, 1976-1977 Buick Skylark, 1977 Oldsmobile Cutlass, 1977 Oldsmobile Cutlass Salon, and 1977 Oldsmobile Cutlass Supreme. The hose is manufactured to exact fit dimensions, with 5/8 in. male inverted flare at one end and 11/16 in. male inverted flare at the other, and measures 33.6 in. (853 mm) in length. Sunsong 3402305 is intended to restore proper hydraulic flow in the steering system while maintaining the pressure capacity needed for reliable operation.

The construction uses high-grade steel tubing with a zinc coating to resist corrosion from humidity, road salt, water, and grime. The hose assembly is also subjected to high-pressure quality testing before leaving the factory. This makes 3402305 a practical replacement choice for owners servicing a Buick Riviera, Oldsmobile Toronado, or other listed GM models that require a pressure-side steering hose with the specified fittings and length.

This part cross-references Gates 355890 for the same application.

What It Helps Fix

• Power steering fluid leaks at the pressure line
• Loss of steering assist caused by hose failure
• Noise or erratic steering from pressure loss in the hydraulic circuit
• Corrosion-related deterioration of the original steel line
• Fitment issues when replacing an aging pressure hose on listed Buick and Oldsmobile models

Installation Notes and Tips

Verify the end fittings, hose length, and routing against the original line before installation. This assembly uses male inverted flare connections and does not list a bracket or power steering switch port. Inspect mating surfaces, flare seats, and adjacent steering components for wear or contamination before connecting the new hose.

Quality Assurance

Sunsong states that each hose is pressure tested before it leaves the factory. The pressure line is engineered to exceed original equipment performance standards, with published pressure and strength ratings that support dependable service in the steering system.
