Detailed Product Description and Specifications

This power steering pressure line hose assembly from Sunsong features a robust CSM (chlorosulfonated polyethylene) hose material, known for its resistance to heat, oil, and abrasion. The hose measures 28.6 inches (726 mm) in length, providing an exact replacement for the original component in Cadillac DeVille, DTS, and Seville vehicles.

The absence of a bracket simplifies installation and reduces potential points of failure.

Common Applications and Problem Resolution

This power steering pressure line hose assembly is used to maintain proper hydraulic pressure in the power steering system. It addresses several common issues, including:

• Leaking or cracked power steering hoses causing fluid loss
• Reduced steering responsiveness due to pressure drops
• Noise or whining from the power steering pump caused by air entering the system
• Swollen or deteriorated hose material affecting fluid flow
• Replacement of worn or damaged original equipment hoses

When installing the Sunsong 3402551 hose assembly, ensure the fittings are clean and free of debris to prevent leaks. The male o-ring fittings require proper seating to maintain system pressure. Since this assembly does not include a bracket, verify that the hose is securely routed and supported to avoid contact with moving parts or excessive vibration.
