Mishimoto Aluminum Radiator for Ford 6.0L Powerstroke 2003–2007 — Direct-Fit, Two-Row Core

The Mishimoto MMRAD-F2D-03 is a direct-fit, all-aluminum performance radiator built to improve cooling for 2003–2007 Ford 6.0L Powerstroke trucks without any cutting or modification.

If you drive or work with a Ford F-250, F-350, F-450, F-550 or Excursion powered by the 6.0L Powerstroke, this radiator is engineered to replace the factory unit with a more durable, higher-capacity solution. Mishimoto designed the unit to balance lightweight construction with reinforced tanks and precision brazing so it withstands heavy towing, repeated use, and higher under-hood temperatures.

How does this radiator help during heavy towing or hot weather?

The Mishimoto radiator increases heat rejection compared with the stock cooler by using a dense, two-row aluminum core and reinforced end tanks, which together reduce operating temperatures under load. Cooler running temps mean more consistent engine performance and less thermal stress on related components.

• Two-row brazed aluminum core for efficient heat transfer
• Strong TIG-welded aluminum end tanks for durability
• Trans cooler integrated with M18x1.5 fitting for reliable transmission cooling
• Magnetic drain plug for easier maintenance and debris capture

Is this radiator easy to install on my 2003–2007 Ford 6.0L?

Yes — Mishimoto engineered this radiator as a direct-fit replacement so installation is straightforward and uses factory mounting points. No cutting, trimming, or custom brackets are required, making it suitable for owners who prefer a bolt-in upgrade.

• Direct factory fit for 2003–2007 Ford 6.0L Powerstroke models
• Pre-sized inlet/outlet ports that match stock plumbing (1.77" inlet, 1.97" outlet)
• Compatible with stock and many modified setups without alteration
• Includes magnetic drain plug to simplify coolant changes

What are the physical and material specifications I should know?

The radiator uses a lightweight two-row core and aluminum end tanks for a strong yet low-mass assembly. Core and overall dimensions are provided so you can verify fitment against your truck’s mounting space and service clearances.

• Overall: approximately 34.5" high x 30.2" wide; core roughly 29" x 28.5"
• Core thickness about 1.45" with 2 rows for increased surface area
• Tank wall thickness near 0.09" and fully aluminum construction
• Transmission cooler port M18x1.5 for OEM-style hookup

Will this radiator work with modified engines or performance upgrades?

The Mishimoto MMRAD-F2D-03 is suitable for stock and many modified 6.0L Powerstrokes, especially when cooling becomes a limiting factor. For extreme power levels or heavily altered cooling circuits, check coolant flow and fan capacity to ensure optimum system balance.

• Designed to support higher thermal loads typical of towing and moderate performance upgrades
• Direct-fit simplifies swapping from OEM while improving thermal headroom
• Consider upgraded fans or coolant routing if you run extreme boost or heavy-duty tow packages
• Lifetime coverage from Mishimoto for long-term peace of mind

Who is this for: Drivers and fleet owners who need a reliable, long-lasting cooling upgrade for 2003–2007 Ford trucks with the 6.0L Powerstroke. It fits owners who tow or haul regularly, enthusiasts upgrading cooling performance, and anyone looking for an easier, durable replacement that installs without fabrication.
