6.7L Powerstroke

If you remove the body from your 2011-2019 Ford F-Series Super Duty, you'll be left with less of a truck chassis and more of a factory. This assembly line is spec'd out for one product, made to order torque shipments, and you're the primary customer. Like a non-truck-based factory, the process is a group effort, with every component depending on each other to create the final product. The 6R140 TorqShift transmission mated to the 6.7L Powerstroke is the torque factory's distribution wing, and we felt that it was time for an expansion.

It's no secret that Ford's Super Duty trucks are towering metal machines, which require massive amounts of cooling. The stock liquid-to-liquid transmission cooler provides adequate cooling in a compact package, but it has its limitations. Some Powerstrokes need extra cooling power, especially when it comes to towing or hauling a heavy payload. We already went over this concept in our last post, so let's dive into our final production-level transmission

No matter the size, shape, or purpose of your vehicle, keeping engine oil temperatures in check is vital. However, some vehicles, like the 6.7L Powerstroke, require a little more cooling power. The stock liquid-to-liquid cooler is adequate for most Ford F-series owners. Yet, these types of coolers have their faults and limitations, which we're already improving on.

When we last left off, we developed our prototype block-off plate to ensure a leak-free connection to our new oil cooler. Since our last post, our plate has received a makeover for an even better look.

With the block-off plate complete, our engineer set their focus

Many believe that the key to a great truck is a powerful engine when, in reality, the transmission can make or break a truck. Your 2011+ Ford F-Series equipped with the 6.7L Powerstroke was delivered with enough torque to spin the Earth off its axis. Still, without a sturdy transmission distributing that power, you're left with gear confetti in a transmission fluid stew. In short, maintaining proper temperatures in your Powerstroke is vital to keep it towing, pulling, and hauling to its full potential. It's about time the 6.7L was due for a cooling upgrade.

Before we can dive into the improvements, we need to understand the OEM system fully. In 2011, Ford upped the ante in the heavy-duty truck segment with the 6.7L Powerstroke, complete with all the technology to earn the Super Duty moniker, specifically the addition of an entire secondary cooling system. This system's focus is dissipating heat from the air-to-water intercooler and channels coolant through several of the vehicle's other

Cooling is one of the basic needs of any engine, and for a workhorse like the 2011-2019 Ford 6.7L Powerstroke, any failure in the cooling system can be disastrous.

The 6.7L Powerstroke's cooling system is divided into two parts. The primary cooling system cools the engine, engine oil, transmission, and EGR. It also supplies heat to the cabin via the heater core. The secondary cooling system focuses on performance, cooling the air-to-water intercooler and the fuel. Both systems have a common weak point, however: their respective degas tanks.

Like almost every manufacturer,

Attention to detail is key to keeping any hardworking truck healthy. In our quest to protect the lifeblood of the 2011-2019 Ford 6.7L Powerstroke, we've thought of those details. But before we look at our design, let's recap our last post on the stock oil cooler.

The stock 6.7L oil cooler is a simple stacked-plate design that uses the engine coolant to warm and cool the oil. The inside of the cooler is separated into two sets of fins. Oil flows through one set of fins while coolant flows through the other. Once the oil temp exceeds the coolant temp, the coolant helps pull excess heat from the oil and releases it through the radiator. This design is adequate for a stock truck, but with more power, or heavy towing, comes more heat.

To get started on our design, we removed the

The goal was simple: take what we learned from developing our 2008-2010 6.4L Powerstroke upper support bar and apply it to the next generation 2011-2016 6.7L Powerstroke.

A little over two years ago we dove headfirst into developing our 2008-2010 6.4L Powerstroke upper support bar. Since then, we've been developing more products for trucks and the Powerstroke platform. With every project, two points ring clear. First, Powerstroke owners need a truck that can be powerful and reliable above all else. Second, nothing destroys a heat exchanger faster than flex. We can add as many safeguards against core stress as we want,
