Alright, it is finally time to see how our engineering team did with the development of this product! First, we measured the physical properties of the Mishimoto radiator compared to the factory radiator. Our first chart highlights the most common selling feature of a performance radiator: core thickness.

Mishimoto vs. factory radiator core thickness

We squeezed out as much additional core thickness as possible without causing any fitment concerns with factory equipment. The factory core came in at just under 1.7" thick, while the Mishimoto radiator measures 1.95" thick, making the Mishimoto radiator 13% thicker than the factory radiator. This additional core thickness allows our product to provide a greater fluid capacity and promote improved efficiency, which is reflected in the following charts. Our second chart shows the improvements made in

Time to install our prototype radiator into a test vehicle to make sure that it fits perfectly. Luckily, we were able to check fitment on the same donor vehicle we used for our last round of testing. Once the truck rolled into the shop, we quickly installed our prototype radiator shown at the end of our last post. Check out a few shots taken during the installation process!

Once we confirmed that the primary radiator mounting points fit perfectly, we installed the shrouding for the top of the radiator as well as the mechanical fan and shroud. As with any test fit, we checked critical clearances to ensure that hoses and electrical components

Now that we had our project objectives outlined, we could bring in a vehicle to begin the first stage of product development. After checking with our local contacts, we were able to locate the 2010 6.7L you see below!

Once the truck was in our shop, we set to work removing the factory radiator. Our goal was to capture all critical dimensions on the radiator so we could use these data points to design our radiator. Additionally, we would be taking measurements on the vehicle to ensure any enlargements we made would not interfere with components on the truck. Check out a few images of the factory radiator

Many of you may be following our other write-up regarding the development of our intercooler for the 2010-2012 6.7L Cummins. Along with designing and testing an incredibly efficient intercooler, we also worked to improve the engine cooling efficiency by crafting a performance aluminum radiator. A typical enthusiast may be wondering, why would I want to upgrade my radiator? Couldn't I spend that money on modifications that make my truck faster, louder, and more fun? Possibly, but keep in mind the benefits of an aluminum radiator upgrade. First, the improvement in reliability is a huge factor for many of our consumers. The factory radiator is constructed from an aluminum core mated to plastic end tanks. The connection point uses a rubber gasket which is then crimped to the core to provide an appropriate seal.
