Tired of constantly filling your 2011-2016 Ford 6.7L Powerstroke radiator with coolant because you have a leak? Or, maybe you?re tired of seeing that coolant puddle on your garage floor every morning. Either way, this Mishimoto Essentials Bundle for the 2011-2016 Ford 6.7L Powerstroke has you covered. This kit includes everything you need to fortify your 6.7L and ensure it runs cool in any situation. The first two components in this bundle are designed to keep your engine running cool and wIt'stand the rigors of a powerful work truck. The Mishimoto all-aluminum 6.7L primary and secondary radiators are constructed from high-quality, aircraft-grade aluminum with 100% brazed aluminum cores. The cores are then TIG-welded to aluminum end tanks for superior durability and longevity. Our primary radiator boasts a 37% increase in coolant capacity and 20% greater surface area than the stock radiator to keep your engine running cool. It also utilizes extruded tubes with internal struts for increased strength and pressure tolerance. To make sure the air going into your engine stays cool, our secondary radiator utilizes a 19% thicker core to reduce coolant temperatures by up to 7 F. The reduced coolant temperatures mean your charge air cooler can run up to 6 F cooler and keep your intake air cooler in turn. Our secondary radiator also includes both thermostat housings for a clean and simple installation. Couple these radiators with our upper support bar and silicone hoses, and you have a recipe for a cool, leak-free 6.7L. Engineered right here in Delaware, our upper support bar is constructed of heavy-duty steel and firmly secures to your truck with cast-steel anchor points. All that steel minimizes front end flex, improving the truck's rigidity, and saving your radiator. Of course, all of the components in this kit are backed by the Mishimoto Lifetime Warranty; so you'll never have to worry about leaks or poor performance ever again
