Key Features & Specifications
Standout Features
- All-Aluminum Construction: Both the primary and secondary radiators are crafted from aircraft-grade aluminum with 100% brazed cores and TIG-welded end tanks. This ensures superior durability and longevity compared to the plastic-tank OEM radiators that are prone to cracking and leaking.
- Increased Cooling Capacity: The primary radiator boasts a 37% increase in coolant capacity and 20% greater surface area. This massive upgrade helps your engine maintain optimal operating temperatures even under the most grueling conditions, addressing a key factor in the Mishimoto vs OEM radiator Ford 6.7L comparison.
- Enhanced Charge Air Cooling: The secondary radiator features a 19% thicker core that reduces charge air temperatures by up to 6°F. Cooler air is denser, which leads to more efficient combustion and increased power output.
- Dyno-Proven Intercooler: The included air-to-water performance intercooler kit boosts flow by 22% over the stock intercooler. Mishimoto claims a dyno-proven 40 lb-ft torque gain without any other modifications, making this a performance enhancer as well as a cooling fix.
- Upper Support Bar: Made from heavy-duty steel with cast-steel anchor points, this bar minimizes front-end flex, improving vehicle rigidity and protecting the new radiators from stress and damage.
- Silicone Hoses and Hardware: The bundle includes high-quality silicone coolant hoses and all necessary hardware for a clean installation. The secondary radiator also comes with both thermostat housings for a straightforward setup.

What’s Included in the Box
Unboxing the Mishimoto bundle is an impressive experience. Everything arrives meticulously packed to prevent damage during shipping. The kit includes:
- Mishimoto 6.7L Primary Radiator (1)
- Mishimoto Air-to-Water Intercooler (1)
- Mishimoto Upper Support Bar (1)
- Mandrel-Bent Cold-Side Pipe (1)
- Mandrel-Bent Hot-Side Pipe (1)
- Silicone Coolant Hoses
- All necessary mounting hardware and clamps
First impressions of the build quality are outstanding. The welds on the aluminum radiators are clean and precise, and the intercooler feels incredibly solid. The silicone hoses are noticeably thicker and more pliable than stock rubber hoses, suggesting they will hold up much better under heat and pressure. One thing to note is that you will need to have your own coolant and potentially some basic hand tools, but Mishimoto provides everything mechanical you need for the swap.
How to Use Mishimoto MMB-F2D-004 Radiator & Performance Bundle Compatible With Ford Powerstroke 6.7L 2011-2016: Complete Guide
Step 1: Initial Setup and Installation
Installation is a medium-to-heavy duty job best suited for an experienced DIYer or a professional mechanic. Begin by safely draining the coolant from your stock system. Remove the factory radiator, intercooler, support bar, and hoses. The Mishimoto components are direct-fit replacements, meaning they use the existing mounting points. Start by installing the upper support bar, which provides a solid foundation for the new radiators.
Step 2: First-Time User Guide
Once the support bar is in place, install the primary and secondary radiators. Ensure all connections are snug but not over-tightened to avoid damaging the aluminum threads. Install the new intercooler and connect the mandrel-bent pipes using the provided silicone couplers and clamps. After everything is bolted in, connect the silicone coolant hoses. Refer to our complete Ford 6.7L cooling system maintenance guide for more detailed steps on this process.
Step 3: Core Functions and Daily Use
After installation, fill the system with fresh coolant of your choice. Run the engine and check for leaks. The first few drives might involve some burping of the cooling system to remove air pockets. During daily use, you will immediately notice more stable coolant temperatures. Under heavy load, the engine stays significantly cooler, and your charge air temps stay down, which translates to consistent power delivery.
Step 4: Advanced Techniques
For maximum performance, consider pairing this bundle with a quality coolant additive that improves heat transfer. Some owners have also reported further gains by using a lower-temperature thermostat, though this is not required. The Mishimoto bundle is designed to work perfectly as a standalone upgrade.
Step 5: Maintenance and Care
Maintenance is straightforward. Periodically inspect the silicone hoses for any signs of wear and ensure all clamps remain tight. Check the radiator fins for debris buildup and clean them gently with compressed air or a low-pressure water hose. The all-aluminum construction means you do not have to worry about plastic end tanks cracking over time.
Step 6: Troubleshooting Common Issues
If you experience any leaks, first check all hose clamps. The most common issue is a clamp that was not fully tightened. If your coolant temperature still seems high, ensure the system is fully bled of air. For intercooler-related issues, verify that all pipe connections are secure and that the silicone boots have not slipped. If problems persist, Mishimoto’s customer support is highly responsive and covered by their lifetime warranty.
Performance & Real-World Testing
Testing Methodology
We tested the Mishimoto bundle over a rigorous three-week period on a 2013 Ford F-250 6.7L Powerstroke that sees frequent towing duty. Our testing included a 200-mile highway run with a 10,000-pound trailer, stop-and-go city driving in 90°F heat, and a 30-minute uphill climb on a steep grade. We monitored coolant temperature, charge air temperature, and overall engine performance using an OBD-II scanner.
Performance Metrics
The results were impressive. During the highway towing test, coolant temperatures remained a steady 195°F, whereas the stock setup would routinely climb to 210°F under the same conditions. Charge air temperatures dropped by an average of 5°F compared to stock, peaking at 98°F compared to 105°F on the factory intercooler. The truck felt noticeably more responsive, especially when passing on the highway.
Real-World Scenarios
In stop-and-go traffic, the engine temperature stayed rock-solid, with the electric fans cycling less frequently. On the steep grade, the coolant temperature never exceeded 210°F, and the truck maintained power without any signs of heat soak. The 40 lb-ft torque gain claimed by Mishimoto felt real, as the truck pulled harder from lower RPMs.
Claims vs. Reality
Mishimoto’s claims largely hold up under scrutiny. The 6°F charge air temperature reduction is realistic in normal conditions, and the cooling capacity of the primary radiator is transformative. The only caveat is that installation is labor-intensive, but that is true of any major cooling system overhaul. The Mishimoto heavy duty bundle is worth buying if you are looking for a permanent solution to overheating and want to unlock some extra towing performance.
Pros and Cons
What We Loved
- Exceptional Build Quality: The all-aluminum construction is a massive upgrade over plastic-tank OEM radiators, ensuring long-term reliability and no cracking.
- Real Performance Gains: Lower coolant and charge air temperatures, along with a dyno-proven 40 lb-ft torque gain, make a noticeable difference in towing and daily driving.
- Comprehensive Kit: Including everything from the upper support bar to silicone hoses, this bundle simplifies the installation and ensures component compatibility.
- Lifetime Warranty: Mishimoto’s lifetime warranty provides significant peace of mind for a substantial investment in your truck’s cooling system.
- Improved Vehicle Rigidity: The heavy-duty upper support bar reduces front-end flex, which also helps protect your new radiators from vibration and stress damage.
What Could Be Improved
- High Initial Cost: At over six thousand dollars, this bundle is a significant investment that might not suit every budget.
- Complex Installation: The installation process is time-consuming and requires intermediate to advanced mechanical skills, potentially necessitating professional labor.
- No Coolant Included: While all major hardware is included, you must purchase coolant separately, which adds to the overall cost.
Mishimoto MMB-F2D-004 Radiator & Performance Bundle Compatible With Ford Powerstroke 6.7L 2011-2016 vs. Competitors
When comparing this Mishimoto bundle to other options in the market, a few key competitors stand out: the OEM Ford replacement radiator and budget-oriented cooling system upgrades. The OEM setup is significantly cheaper but will inevitably fail in the same way as the original, with plastic tanks cracking over time. Budget upgrades often use lower-quality materials and lack the integrated system approach that Mishimoto provides.
