What It Helps Address

• Power steering fluid leaks from a worn or damaged pressure line
• Steering noise caused by pressure loss in the hydraulic circuit
• Hard or inconsistent steering effort from restricted hose flow
• Corrosion-related hose deterioration on older Cadillac steering systems
• Fitment issues when replacing an original pressure hose assembly

Installation Notes and Tips

Verify the end fitting sizes before installation: 5/8 in. male inverted flare on one end and 11/16 in. male inverted flare on the other. Confirm hose routing matches the original layout on the vehicle and inspect adjacent steering components for wear before installing the new line. This hose assembly does not include a bracket or PS switch port.
