Description

Keep your Pontiac GTO on the road and out of the shop by upgrading to the Mishimoto Pontiac GTO Performance Aluminum Radiator. Stock plastic radiators are prone to significant wear from constant temperature variation. Our radiator is constructed from high-quality aluminum for optimal heat dissipation and superior reliability. This radiator features a large, efficient, and robust 2-row brazed aluminum core which provides optimal coolant temperatures on the street and track. The Mishimoto Pontiac GTO Performance Aluminum Radiator features an in-tank transmission fluid cooler compatible with stock transmission cooler lines, making this a true bolt-on performance radiator. This radiator includes a Mishimoto Magnetic Oil Drain Plug M12 x 1.5 which removes any metal fragments from your coolant system. For further cooling system protection this radiator includes the Mishimoto 1.3 Bar High-Pressure Radiator Cap which effectively raises the boiling point of your coolant, providing a safer and more efficient system. This radiator also features an increase in capacity of 0.64 L of fluid and provides a proven reduction in coolant temperatures of 15 degrees Fahrenheit. Whether you are making a pull down the highway or cruising through the mountains, the Mishimoto Pontiac GTO Performance Aluminum Radiator will keep your GTO cool. As with all our products, this radiator includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
