• Description:

  This genuine Ford engine oil cooler assembly, LC3Z-6A642-C, is the OEM cooling module that keeps engine oil temperature in check on 2020-2022 Ford F-250, F-350, F-450, and F-550 Super Duty trucks equipped with the 6.7L Power Stroke diesel engine. Mounted in the engine's oil circuit, the cooler routes hot oil through a heat exchanger cooled by engine coolant, pulling heat out of the oil before it recirculates through the bearings, pistons, and turbocharger bearing housing. A failing cooler on this platform typically shows up as elevated oil temperature warnings on the dash, coolant contamination with an oily sheen or a milky appearance in the coolant reservoir, oil in the coolant system or coolant in the oil, external oil seepage at the cooler housing gaskets, or a persistent loss of coolant with no visible external leak. Internal core cracking from thermal cycling and corrosion are the most common causes of cross-contamination failures on high-mileage 6.7L Power Stroke trucks. Ford's catalog lists this part as the Oil Cooler Assembly, and it includes the housing, internal cooler core, and integrated filter mounting provisions used on this generation of Super Duty. Replacement calls for new gaskets and O-rings at every sealing surface, careful torque sequencing on the mounting fasteners, and a full engine coolant flush and refill to remove any contaminated coolant left in the system. Because oil and coolant cross-contamination can quickly damage bearings and the turbocharger if left unaddressed, prompt replacement at the first sign of these symptoms is recommended. This is a direct-fit replacement for the factory cooler on qualifying 6.7L diesel Super Duty applications.
