This high-capacity aluminum radiator is built to support the cooling demands of 2017–2019 Chevy and GMC 6.6L Duramax diesel engines.
The Mishimoto performance radiator is engineered for durability and efficiency, utilizing a full aluminum TIG-welded design with precision-machined components. Its increased core thickness and surface area enhance heat dissipation, helping to maintain optimal coolant temperatures even under heavy loads, towing, or performance tuning. Designed as a direct fit replacement for the factory radiator, it offers improved longevity and reliability without requiring custom modifications.
The fully brazed aluminum construction features a high-density core and robust end tanks, making it more resistant to failure under thermal stress than the stock unit. Ideal for daily use, towing, or off-road scenarios, it’s a practical solution for owners looking to enhance thermal performance and prevent overheating.
