Detailed Description

This Sunsong power steering pressure line hose assembly is made for steering systems that require a durable, direct-fit replacement. The steel tubing is zinc-coated to resist rust and corrosion from humidity, road salt, water, and grime, while the CSM hose material supports long-term service in demanding underhood conditions. The 3401746 is a practical replacement choice for Chevrolet G10, G20, and G30 vans and GMC G1500, G2500, and G3500 vans within the listed years and equipment notes.

This part cross-references Dayco 71231 and Gates 354960 for the same application. The Sunsong 3401746 is also referenced by interchange numbers 36-354960, 979-2127, and 7841688.

What It Helps Resolve

• Power steering fluid leaks from a worn or damaged pressure hose
• Steering noise caused by pressure loss in the hydraulic line
• Hard steering from restricted or failing hose flow
• Corrosion-related hose deterioration on older GM vans
• Fitment issues from incorrect hose length or fitting size

Before installation, confirm the 16 mm and 18 mm male O-ring connections match the vehicle’s steering gear and pump ports. Verify hose routing, clearance, and bracket locations against the original line, and inspect related seals and fittings for wear before reassembly.

Quality Assurance

Each hose is pressure tested at the factory before shipment to support trouble-free installation and operation. Sunsong builds this pressure line to exceed original equipment performance standards for strength, corrosion resistance, and service life.
