Treat your modern muscle car to a dose of reliability with the Mishimoto Pontiac GTO Performance Aluminum Radiator. This radiator is engineered specifically for the 2004 Pontiac GTO with efficient cooling in mind. For optimal heat dissipation and reliability, this radiator features an all-aluminum construction, including TIG-welded end tanks and a fully brazed 2-row core.

This large, efficient, and robust core provides an increase in capacity of 0.64 L and a reduction in coolant temperatures of 15+ degrees Fahrenheit, making it ideal for use on and off the track. This radiator features an in-tank transmission fluid cooler compatible with stock transmission cooler lines, making this a true bolt-in performance radiator.
