Common Problems This Part Can Help Address

• Power steering fluid leaks from a worn pressure hose
• Hard or inconsistent steering assist caused by pressure loss
• Cracked, swollen, or deteriorated hose material
• Corrosion on steel line sections exposed to road debris and moisture
• Noise or steering performance issues related to restricted fluid flow

Installation Notes and Tips

Verify the end fitting sizes, hose routing, and overall length before installation. This assembly uses male O-ring connections and is intended for pressure-side steering service on the listed Buick Century and Oldsmobile Cutlass Ciera applications. Inspect mating seals, brackets, and surrounding steering components during replacement to confirm the system is clean and free of damage before refilling and bleeding the power steering system.
