Detailed Description

The Sunsong 3401492 pressure hose is built to restore the hydraulic connection between the power steering pump and tee on supported vehicles. It is manufactured to exact fit standards and is designed around the original routing and connection style used on the application. Sunsong 3401492 also reflects the brand’s focus on pressure hose durability, corrosion resistance in the tubing, and factory-level quality testing before release.

This part cross-references Edelmann 70404 and Gates 357190 for the same application. It is a direct-fit option for vehicles such as the Chevrolet Caprice, Chevrolet Monte Carlo, Buick Regal, Oldsmobile Cutlass, Oldsmobile Cutlass Supreme, Pontiac Grand Prix, Pontiac Bonneville, and Pontiac Parisienne in the listed years and configurations.

What It Helps Fix

• Power steering fluid leaks at the pressure line
• Loss of steering assist from a damaged hose
• Cracked, worn, or pressure-fatigued hose sections
• Noise or erratic steering caused by restricted fluid flow
• Corrosion-related hose deterioration in older steering systems

Installation Notes and Tips

• Verify pump-to-tee routing before ordering; this hose is not for other steering line positions.
• Confirm 16 mm male O-ring fittings on both ends match the vehicle connection points.
• Check hose length and routing clearance against the original part before installation.
• Inspect related seals, clamps, and mounting points for wear during replacement.
• Follow the vehicle service procedure for bleeding the power steering system after installation.

Quality Assurance

Sunsong states that each pressure hose is pressure-tested before leaving the factory. The hose assembly is also built to exceed original equipment performance standards, with high-pressure capability and corrosion-resistant tubing construction for long service life.
