• Repairing a hose with abrasion wear near adjacent engine components
• Servicing cooling system leaks on Kia Optima and Hyundai Sonata models

Installation Notes and Tips

Verify the hose routing, end diameters, and lower-position fitment before installation. Inspect the mating necks, clamps, and surrounding cooling system components for wear or corrosion, and replace any damaged parts as needed. After installation, refill and bleed the cooling system according to the vehicle service procedure and check for leaks at operating temperature.
