Mishimoto Aluminium Radiator for Ford 6.0L Powerstroke (2003–2007) — Direct-Fit, Two-Row Brazed Core

The Mishimoto MMRAD-F2D-03 is a direct-fit, all-aluminum performance radiator engineered to replace the factory unit in 2003–2007 Ford 6.0L Powerstroke trucks and Excursions.

Designed specifically for the 6.0L Powerstroke platform, this Mishimoto radiator swaps into F-250, F-350, F-450, F-550 and Excursion applications without cutting or modification. Its two-row brazed-aluminum core and TIG-welded end tanks improve heat transfer and durability over the stock radiator, making it a straightforward upgrade for everyday drivers and heavy-duty users alike.

How does this radiator improve cooling performance?

The Mishimoto unit uses a dense two-row brazed aluminum core and thicker tank construction to move heat away from the engine faster than many OEM units. Improved coolant flow and larger surface area lower operating temperatures under load.

• 29" x 28.5" brazed aluminum core for greater heat dissipation
• Two-row design balances airflow and coolant volume
• TIG-welded aluminum end tanks resist cracking and corrosion
• Magnetic drain plug helps capture debris and ferrous particles

Will it fit my 2003–2007 Powerstroke without modifications?

Yes — Mishimoto built this radiator as a direct factory replacement that installs in the stock mounting points. No cutting, trimming, or custom brackets are required when fitting compatible Ford models.

• Direct-fit for 2003–2007 Ford 6.0L Powerstroke applications
• Factory inlet/outlet locations preserved for plug-and-play installation
• Includes transmission cooler port: M18 x 1.5 thread
• Compatible with OEM hoses and clamps (sizes listed below)

What are the key dimensions and connection sizes?

The radiator’s overall and core dimensions are tuned to provide ample cooling without changing the truck’s mounting geometry. Connection sizes match common Powerstroke plumbing for straightforward hose installation.

• Overall size: 34.5" H x 30.2" W; core size: 29" H x 28.5" W
• Core thickness: 1.45" for efficient heat exchange
• Inlet: 1.77" (45 mm) — Outlet: 1.97" (50 mm)
• Tank wall thickness ~0.09" for stronger end-tank longevity

How durable is the Mishimoto radiator for towing and heavy use?

Constructed entirely from brazed aluminum with TIG-welded end tanks, this radiator is built to withstand the vibrations and thermal cycles common in towing and commercial use. The design reduces risk of tank failure and helps maintain consistent cooling under load.

• 100% brazed aluminum core resists core separation
• TIG-welded end tanks provide structural strength
• Magnetic drain plug improves serviceability and debris capture
• Backed by Mishimoto’s lifetime coverage for peace of mind

Who is this for? Owners of 2003–2007 Ford 6.0L Powerstroke trucks and Excursions who want a reliable, higher-capacity cooling solution without fabrication work will benefit most. Whether your truck is daily-driven, used for regular towing, or modified for performance, this direct-fit Mishimoto radiator offers a durable, easy-to-install upgrade to reduce overheating risk and improve thermal consistency under load.
