Detailed Description

Sunsong 3402298 is a replacement power steering pressure hose designed for classic GM van platforms, including Chevrolet G10, G20, and G30 and GMC G15/G1500, G25/G2500, and G35/G3500 applications. It is built around the original routing and connection style used on flared-fitting systems, with a 39.5-inch length and male inverted flare ends sized 11/16 in. and 5/8 in. The part number 3402298 is a practical match for owners servicing steering leaks, pressure loss, or deteriorated hose assemblies on these vehicles.

This hose uses high-grade steel tubing with zinc plating to improve resistance to rust, road salt, water, grime, and humidity. Sunsong also subjects each hose to high-pressure testing before shipment to verify sealing and operation. This part cross-references Gates 355370 for the same application.

What This Hose Helps Address

• Power steering fluid leaks at the pressure line
• Loss of steering assist from a damaged hose
• Cracked, corroded, or worn original pressure tubing
• Improper hose routing or fitment from an incorrect replacement
• Pressure-line failure on aging Chevrolet G10/G20/G30 and GMC van steering systems

Fitment includes specific exclusions for hydroboost-equipped vehicles on several applications, so verify the steering system before installation.
