Grizzly GA304N New Replacement EGR Cooler for 2004.5-2007 Ford 6.0L Powerstroke (Square Cooler)

The Grizzly GA304N is a brand-new, direct-fit EGR cooler designed for 2004.5–2007 Ford 6.0L Powerstroke engines (square-style cooler) and compatible International VT365 applications. It restores proper exhaust gas recirculation cooling so your truck can run correctly again.

Stock 6.0L EGR coolers are a well-known failure point. Over time they crack, allowing coolant into the intake/exhaust or exhaust gas into the cooling system. This leads to coolant loss, white smoke, overheating, and potential further damage. The Grizzly GA304N is built as a high-quality replacement that meets or exceeds original equipment specifications. It is a true bolt-in unit that installs with the included gaskets for a clean, leak-free job—no core charge required.

Key Features

• Direct OE-style replacement (replaces 4C3Z-9P456-AJ, 1845145C97, and related numbers)
• New construction — not remanufactured
• Gaskets included for straightforward installation
• Designed to restore proper EGR system operation and cooling performance
• No core charge

Fitment: 2004.5–2007 Ford 6.0L Powerstroke (F-Series, Excursion, and E-Series with the square EGR cooler). Also fits corresponding late VT365 applications.

A failed EGR cooler is one of the most common (and expensive) problems on the 6.0L. Replacing it with a quality new unit like the Grizzly GA304N gets the emissions and cooling systems working as intended and helps protect the rest of the engine. Ideal for trucks still running the stock EGR system.
