Detailed Description

Built as a power steering pressure line hose assembly, Sunsong 3403023 is intended for vehicles that require a direct OE-style hydraulic line with the correct fitting sizes and length. The steel tubing is zinc-coated to help resist road salt, moisture, grime, and humidity, while the hose assembly is engineered to restore the steering system’s original routing and function on classic Oldsmobile and Pontiac models.

With a 3/8 inch male inverted flare on one end, a 7/16 inch male inverted flare on the other, and a 32.25 inch length, this hose supports accurate replacement on 1968-1970 Oldsmobile 98, 1968-1970 Oldsmobile Delta 88, 1968-1970 Pontiac Bonneville, 1968-1970 Pontiac Catalina, and 1968 Pontiac Grand Prix. The Sunsong 3403023 is a practical choice when replacing a worn or leaking pressure line in these steering systems.

Common Problems This Part Can Address

• Power steering fluid leaks from a cracked or worn pressure hose
• Steering noise caused by pressure loss in the hydraulic line
• Hard or inconsistent steering effort from a failing hose assembly
• Corrosion-related damage to steel tubing and fittings
• Improper fit from a hose that does not match OE dimensions

Installation Notes and Tips

Verify the end fitting sizes, hose length, and routing before installation. Inspect related steering components, line brackets, and sealing surfaces for wear or damage, and replace any compromised parts before filling and bleeding the system. Confirm that the hose follows the original path to avoid contact with heat sources or moving components.

Quality Assurance

Each Sunsong 3403023 hose is pressure-tested before it leaves the factory to help ensure proper operation after installation. The manufacturer also specifies performance targets above original equipment standards, including working pressure, burst pressure, and tensile strength ratings.
