The exchanger itself is unique in its design it uses two thermostats – one incorporated into each end tank – that direct the flow of the coolant as it flows among the numerous passages. Schematics of the secondary Ford 6.7 Radiator system (© Ford Motor Company) This system is similar to those found on most other vehicles. It incorporates a large radiator (the primary Ford 6.7 radiator) mounted forward of the engine, but behind the other heat exchangers (secondary Ford 6.7 radiator and AC condenser). The first, more conventional system cools the engine by sending coolant through passages in the block and to a heat exchanger up front, and also directs coolant to an oil cooler and the heater core. The factory cooling system on the 6.7L Ford Super Duty trucks is very elaborate, and it actually comprises two mostly independent cooling systems that use their own coolant pumps and are almost completely isolated from one another. Wait, the 6.7L has TWO cooling systems? What the… The front of the 6.7L The Secondary radiator is front and center, behind the AC Condenserīefore I go into too much detail on how we will be upgrading this system, let’s review the factory Super Duty radiator setup, so we can understand what’s going on under the hood of this truck to keep everything from getting too toasty. Many of you may know that we have already released a high-performance primary Ford 6.7 radiator, but I am excited to announce that we have been busy developing a Mishimoto Super Duty radiator for the secondary system as well. When we bought our Mustang GT, we didn’t stop there – we bought a turbo model, too. Our engineers at Mishimoto also see the value in the “two can be better than one” mindset. These trucks feature two systems that work in parallel to handle all of the cooling needs in your truck, and both are equally important. This was very much the school of thought that Ford’s engineers adopted when designing the cooling system on the 2011+ F-Series Super Duty trucks, including the F-350, F-450, and F-550. Whether we’re talking about turbochargers on an F-150 EcoBoost, V8 engines in an offshore powerboat, drummers in the Allman Brothers Band, or pieces of Carvel™ Ice Cream Cake for dessert on my birthday, sometimes two is a better option than one.
