Detailed Product Overview

Built for pressure-side steering service, Sunsong 3402079 is a direct replacement hose assembly for the Ford Thunderbird and Mercury Cougar applications listed above. The hose is precision engineered to match the original routing and connection style, helping restore proper steering system function on vehicles equipped with Saginaw steering gear. This part cross-references Gates 354920 and Dayco 71059 for the same application.

Its pressure rating and tensile strength support long-term durability in demanding steering systems, while the OE-style fit helps reduce installation issues on the correct application.

Common Steering Problems This Hose Can Address

• Power steering fluid leaks at the pressure line
• Cracked, worn, or corroded original hose assemblies
• Loss of steering assist caused by pressure-side hose failure
• Noise or erratic steering operation related to fluid loss
• Replacement needs on aging Ford Thunderbird or Mercury Cougar steering systems

Installation Notes and Tips

Confirm the vehicle uses Saginaw steering gear before ordering. Match the end fittings, hose length, and routing to the original assembly on the vehicle. Inspect nearby steering components, seals, and fluid condition during replacement so the new hose can be installed on a clean, properly serviced system.
