Mishimoto Performance Aluminum Radiator for 2005-2006 Pontiac GTO MMRAD-GTO-05

Fits 2005-2006 Pontiac GTO Base models.

Keep your Pontiac GTO on the road and out of the shop by upgrading to the Mishimoto Performance Aluminum Radiator. Factory radiators utilize plastic end tanks prone to cracking and leaking after years of heat cycles. This Mishimoto upgrade is engineered for superior reliability, featuring 100% all-aluminum construction with TIG-welded end tanks for optimal heat dissipation and long-term durability.

At the heart of this radiator is a 2-row brazed aluminum core that increases fluid capacity by 0.64 L while providing a proven reduction in coolant temperatures of 15°F (6°C). For automatic and manual applications, it includes an integrated in-tank transmission fluid cooler compatible with stock lines, making this a true bolt-on performance solution. Each radiator comes equipped with a 1.3 Bar High-Pressure Radiator Cap to raise the boiling point and a Magnetic M12 x 1.5 drain plug to capture metallic debris within the cooling system.
