What It Helps Address

• Power steering fluid leaks from a worn or damaged pressure line
• Loss of steering assist caused by hose failure
• Corrosion-related deterioration in the pressure hose assembly
• Incorrect fitment from a previous replacement hose
• Pressure-related steering system noise or performance issues

Installation Notes and Tips

Verify the end fittings before installation: 14 mm female bubble flare on one end and 16 mm male inverted flare on the other. Confirm hose length and routing against the original part, especially on 1996-1997 Mercedes-Benz C220 and 1997-2000 Mercedes-Benz C230 applications. Inspect mating components, seals, and hard lines for wear or contamination before installing the new hose.
