Show original supplier description
The Engineered Cooling Products (ECP) heavy-duty aluminum radiator is engineered as a direct replacement for the 2005-2013 Corvette C6 models equipped with the LS3 engine and an automatic transmission. It addresses the need for enhanced cooling with its robust construction and design. This radiator boasts an all-aluminum build, featuring a heavy-duty 2-row core that utilizes 1.0" tubes arranged with high density. This configuration offers superior cooling capacity, outperforming many other high-performance radiators. The construction is entirely TIG welded, providing a strong and reliable seal without the use of epoxy, which can degrade over time. For automatic transmission applications, a heavy-duty transmission cooler is integrated directly into the radiator assembly. Hose connections for both the upper and lower radiator hoses are standardized at 1-5/16". The overall external dimensions measure 29-1/4" wide by 18-3/4" tall, while the core itself is 23-1/4" wide by 18" high, ensuring a fit within the specified C6 Corvette engine bay. It is important to note that this radiator will not fit C6 Corvettes that feature an integrated engine oil cooler within the factory radiator. The radiator has a natural aluminum finish, which may appear as shown in product images after being cleaned with standard detailing products.
