Detailed Description

This Sunsong power steering pressure line hose assembly, part number 3401444, is built for direct replacement use on 1990-1995 Chevrolet Astro and 1990-1995 GMC Safari models. The hose assembly uses male O-ring connections at both ends and is sized for the listed fitment, helping maintain proper routing and sealing in the steering hydraulic circuit. Sunsong also subjects each hose to high-pressure testing before it leaves the factory to verify performance and installation readiness.

This part cross-references Dayco 71771 and Gates 359570 for the same application.

What It Is Used For

• Restoring steering assist when the original pressure hose is leaking
• Replacing a hose with cracked, swollen, or deteriorated CSM material
• Addressing fluid loss at worn male O-ring connections
• Correcting pressure-line issues on Chevrolet Astro and GMC Safari vans
• Replacing a corroded steel hose assembly exposed to road salt and moisture

Installation Notes and Tips

Verify end sizes, routing, and connection style before installation. Inspect the power steering system for contamination, damaged seals, or worn mating surfaces that could affect the new hose. Confirm the hose follows the original path and clears nearby components to avoid chafing or heat exposure.

Quality Assurance

Sunsong pressure hoses are manufactured to exceed original equipment performance standards, with corrosion-resistant steel tubing and factory pressure testing for consistent operation. The design focus on exact fit and high-pressure durability supports reliable service in the steering system.
