Detailed Description

This Sunsong power steering reservoir hose is made to replace the return-side hose on Subaru Impreza models from 2009 through 2012. The hose is sized with 16 mm ID hose connections at both ends and measures 25.2 inches long, helping support a proper routing and secure connection in the steering system. Sunsong 3403730 is built for low-pressure return flow where heat and fluid exposure are common.

According to the manufacturer, the hose assembly is engineered to meet or exceed original equipment performance standards and uses corrosion-resistant steel tubing with zinc plating where applicable. The design also accounts for wear items and vehicle-specific fitment details to restore the original hose layout on the Subaru Impreza. This part cross-references Subaru 34611AG220 for the same application.

Common Steering System Issues

• Power steering fluid seepage at the reservoir return line
• Cracked or hardened hose material from heat and age
• Corrosion on exposed hose routing components
• Loose or poor-fitting return hose connections
• Noise or inconsistent steering assist caused by fluid loss

Installation Notes and Tips

Verify hose routing, end size, and length against the original Subaru Impreza hose before installation. Inspect nearby brackets, grommets, and protective sleeves for wear, and replace any damaged related components during service. Confirm the system is filled and bled properly after installation to restore normal steering operation.

Quality Assurance

Sunsong 3403730 is manufactured to OE-style fit and performance expectations for the specified Subaru Impreza applications. The hose is built for return-line service with a 250 psi maximum working pressure rating and corrosion-resistant construction details intended for demanding underhood and road conditions.
