Product Description

The Mishimoto MMOC-F2D-94 is a direct-fit replacement oil cooler engineered for the 1994-2003 Ford 7.3L Powerstroke diesel engine across the F-250, F-350, F-450, E-350 Econoline, and Excursion platforms. The 7.3L Powerstroke uses a liquid-to-liquid oil cooler that transfers heat from the engine oil into the coolant circuit - a design that works well but is known to clog with debris and develop O-ring leaks as the truck ages. On the 7.3L specifically, maintaining proper oil temperature is doubly critical because the engine's HEUI injection system uses high-pressure oil to operate the injectors. A failing oil cooler puts both engine lubrication and fuel delivery at risk.

This Mishimoto replacement restores full oil cooling efficiency with an all-aluminum construction that meets or exceeds OEM Ford specifications, and it includes fresh gaskets and O-rings for a clean, leak-free installation. Factory-style fittings integrate directly with OEM hoses and sensors for a bolt-on swap. Mishimoto recommends flushing the coolant system and adding a coolant filter when performing this replacement to prevent future clogging. Professional installation is recommended. Backed by the Mishimoto Lifetime Warranty, the MMOC-F2D-94 is an essential reliability upgrade for any high-mileage 7.3L Powerstroke.
