Detailed Description

Sunsong 3402758 is a power steering pressure line hose assembly made for Cadillac CTS applications that require a direct replacement pressure hose. It is built with steel tubing protected by zinc plating to help resist moisture, road salt, grime, and other underbody exposure. The hose assembly is precision engineered to match the original routing and connection points, and the design includes the bracket needed for proper mounting. This part cross-references Four Seasons 75046 and Gates 365682 for the same application.

Common Problems This Part Can Address

• Power steering fluid leaks from a worn or damaged pressure hose
• Cracked, corroded, or fatigued hose tubing
• Loss of steering assist caused by pressure-side hose failure
• Noise or erratic steering operation related to fluid loss
• Fitment issues when replacing an aging Cadillac CTS steering line

Installation Notes and Tips

Verify the end fitting sizes and styles before installation: 11 mm male captive O-ring on one end and 16 mm male O-ring on the other. Confirm the vehicle application against the 2008-2014 Cadillac CTS and 2014 Cadillac CTS EPS listing, and inspect the mounting points, routing, and surrounding components before final tightening. Proper system bleeding after installation is important to restore normal steering operation.

Quality Assurance

Each hose is pressure tested before it leaves the factory. Sunsong states that this pressure line is engineered to exceed original equipment performance standards, with corrosion-resistant tubing and a fitment-focused design intended to restore worn wearable components to original condition.
