• Overheating concerns during stop-and-go or high-load driving
• Fitment issues when replacing a right-side Porsche radiator

Installation Notes and Tips

Verify right-side placement before ordering and compare the core dimensions to the original unit. Confirm the vehicle year, model, and body configuration, especially for 2004-2005 Porsche 911 and Boxster applications with brazed cooling fins or 2005 Porsche 911 coupe and cabrio body code 997 notes. Inspect hoses, clamps, and coolant condition during radiator replacement, and bleed the cooling system according to Porsche service procedures after installation.
