• Improper hose sealing at O-ring connections
• Noise or inconsistent steering feel caused by pressure loss

Installation Notes and Tips

Confirm the 16 mm male O-ring fittings and 80.8-inch length match the original hose before installation. Inspect mating surfaces, seals, and nearby steering components for wear or contamination before connecting the new line. After installation, bleed the power steering system according to the vehicle service procedure and check carefully for leaks under operating pressure.

Quality Assurance
