Detailed Description

This Sunsong power steering pressure line hose assembly, part number 3401995, is made for Cadillac Seville models from 1976 through 1979. It is built to replace the pressure side of the steering system with a hose assembly that matches the original routing and connection style, helping restore proper hydraulic flow and steering response. The use of zinc-coated steel tubing helps resist rust and corrosion from humidity, road salt, water, and grime, which is important for long-term service in exposed underhood and chassis locations. This part cross-references DENSO Auto Parts 5078 for the same application.

Common Problems This Part Can Address

• Power steering fluid leaks from a worn or damaged pressure hose
• Hard steering caused by pressure loss in the hydraulic system
• Noise or hesitation during steering assist operation
• Corrosion-related hose or tube deterioration on older Cadillac Seville vehicles
• Fitment issues when replacing an aging pressure line with the correct OE-style assembly

Installation Notes and Tips

Verify the end fitting sizes and inverted flare connections before installation. Inspect the steering pump, gear, and adjacent lines for wear or contamination so the new hose is not installed into a compromised system. Confirm routing clearance and secure the line to prevent contact with heat sources or moving components. This part number 3401995 is intended for 1976-1979 Cadillac Seville applications only.

Quality Assurance

Each hose is pressure tested before it leaves the factory to help ensure proper operation after installation. Sunsong builds this assembly to exceed original equipment performance standards, with materials and construction selected for durability and corrosion resistance.
