Built for Volvo Steering System Service

This pressure hose assembly is made to replace the original power steering pressure line on Volvo S80 and Volvo XC70 models listed above. The Sunsong 3405392 uses corrosion-resistant steel tubing and application-specific components such as brackets and protective pieces where required, helping restore the steering system to original operating condition. This part cross-references Gates 366311 and Edelmann 92857 for the same application.

Common Problems This Hose Can Address

• Power steering fluid leaks from a worn or damaged pressure line
• Loss of steering assist caused by pressure loss in the hose assembly
• Noise or stiffness in the steering system related to fluid flow issues
• Corrosion on the original steel line from road salt, moisture, or grime
• Fitment issues when replacing a deteriorated Volvo S80 or Volvo XC70 hose

Installation Notes and Tips

Verify the end fittings, bracket location, and hose routing against the original line before installation. Inspect nearby seals, clamps, and mounting points for wear so the replacement can be installed cleanly and aligned correctly. After installation, bleed the power steering system and check for leaks under operating pressure.

Quality Assurance

Each Sunsong pressure hose is pressure tested before it leaves the factory to support trouble-free installation and operation. The hose assembly is engineered to exceed original equipment performance standards for pressure capacity and durability.
