A clogged or leaking oil cooler is a classic 7.3L Powerstroke problem, and the Mishimoto MMOC-F2D-94 is a stock-style replacement for Ford's 7.3L Powerstroke from 1994 to 2003 (T444E). It covers F-Series, E-Series, Excursion and Super Duty applications, with exact years varying by model.
This liquid-to-liquid replacement is made to meet or exceed OEM specifications and ships with new gaskets and oil cooler O-rings, so you are not reusing tired seals. Mishimoto recommends flushing the coolant and fitting a coolant filter kit to help prevent a repeat clog.
Installation is rated medium, with a professional install highly recommended. Mishimoto backs it with a lifetime limited warranty for the original purchaser (receipt required). Order the Mishimoto MMOC-F2D-94 from Track Ready Products and keep your oil, and your engine, in its happy temperature range.
This is a replacement part, so the job is about careful removal and clean mating surfaces. Follow the factory service manual for your engine.
Flush the coolant and consider a coolant filter kit so debris does not clog the new cooler.
Refill with fresh oil and coolant, run the engine to temperature and check for leaks.
