Mishimoto 2010-2012 Dodge 6.7L Cummins Performance Aluminum Radiator, Part 3: Prototype Installation

Key takeaways

    • Performance aluminum radiator for the Dodge. All-aluminum construction with TIG-welded tanks replaces plastic-tank failures common in factory units under sustained thermal stress.
    • Substantial cooling capacity gains. Increases core volume and fluid capacity to reduce coolant temperature spikes during aggressive driving, towing, or track operation.
    • Vehicle-specific engineering eliminates fitment compromise. Direct-fit design mounts without cutting, drilling, or adapter hoses—preserving factory envelope and simplifying installation.
    • Designed and tested in the USA. Mishimoto validates every radiator against real-world thermal stress at its R&D facility and protects with the Lifetime Warranty.

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 do not come in contact with the radiator or shroud. We also checked fan-to-radiator core clearance to be sure we had ample space for engine movement.

Finally, we could attach the radiator hoses, fill the vehicle with coolant, and fire up the engine to bleed the air from the cooling system.

This test fit was successful in that all components fit together just like the factory radiator, and no adjustments of our product design were necessary. Check back with us next time for an evaluation of the physical benefits of our design and an explanation of our testing plans and process.
