Common Problems This Hose Can Address

• Coolant leaks from a cracked or aged hose
• Softening or swelling caused by heat exposure
• Rubber breakdown from ozone or electrochemical degradation
• Poor hose alignment from a non-molded replacement
• Cooling system service on a Porsche 911 with deteriorated original hose routing

Installation Notes and Tips

Verify the hose routing and end diameters before installation. Inspect adjoining tubes, clamps, and sealing surfaces for wear or corrosion, and replace any damaged components before refilling the cooling system. After installation, bleed the cooling system according to factory procedure and check for leaks at operating temperature.
