This direct-fit radiator is designed and specifically engineered to maximize the cooling efficiency of your 1999–2014 Silverado whether it's your daily driver or your everyday work truck.

Thanks to a 92% thicker core, the Mishimoto 1999–2014 Silverado 1500 V8 radiator boasts a 72% increase in coolant capacity over the stock radiator. Surface area is also increased by 69% over stock to make the most use of the air flowing through your Silverado's grille.

With that significant of a size increase, you would expect an equally significant performance increase; and the Mishimoto 1999–2014 Silverado 1500 V8 performance radiator delivers.

Under real-world conditions, this radiator reduced outlet temperatures by 46°F over the stock radiator. In the same testing, the Mishimoto radiator reduced transmission fluid temperatures by 25°F. Lower engine coolant and transmission fluid temps mean that your engine and transmission last longer and perform better.

As with all Mishimoto products, this radiator is backed by Mishimoto's Lifetime Warranty. So whether you're towing your weekend toys or ferrying the kids to school, you can rest easy knowing that your 1999–2014 Silverado 1500's engine and transmission are protected by Mishimoto.
