Koyo 09-13 Nissan GT-R 3.8L (AT) Radiator

This Koyo radiator is built with a dual core design, featuring two rows of 48mm thick aluminum tubes. This construction significantly increases the surface area compared to the stock radiator, allowing for much more efficient heat dissipation. For a 2009-2019 Nissan GT-R, especially one that sees hard driving or track use, keeping engine temperatures in check is critical for performance and longevity. This radiator is designed to handle the increased heat load that comes with spirited driving, helping to prevent overheating and maintain consistent engine performance.

The all-aluminum construction means it's not only strong but also lighter than the factory unit, which can be a small but notable advantage. Koyo uses advanced brazing techniques to ensure a solid bond between the tubes and fins, creating a durable core that can withstand the vibrations and pressures of daily driving and track conditions. The direct-fit design means it bolts into the factory mounting locations, simplifying the installation process. This radiator is a solid option for GT-R owners looking to upgrade their cooling system to better manage engine heat.

When installing this radiator, you'll want to ensure you have fresh coolant on hand, as you'll be draining and refilling the system. It's also a good time to inspect your coolant hoses and thermostat for any signs of wear, as these components work together to keep your engine running at the optimal temperature. This Koyo radiator is a well-built upgrade for your GT-R's cooling system.
