Installation Notes and Tips
Verify the end fitting sizes, hose length, and routing before installation on your Buick Century. Inspect mating surfaces, seals, and surrounding steering components for wear or contamination before connecting the new line. After installation, refill the system with the correct power steering fluid and check for leaks with the engine running and steering cycled through full lock-to-lock movement.
