Cummins 3201150 Oil Cooler Assembly

The Cummins 3201150 oil cooler assembly is a critical component of the engine lubrication system for the KTA19 series marine diesel engines. It utilizes a robust plate-fin construction to transfer heat from the engine oil to the engine coolant circuit, maintaining oil viscosity within specified operating limits. This assembly is engineered to withstand the high thermal loads and vibration profiles inherent in continuous-rated marine propulsion applications, such as the KTA19-M4 rated at 522 kW (700 HP). It features precision-machined mounting flanges and sealed joints to prevent cross-contamination between oil and coolant pathways. Regular inspection and replacement per Cummins maintenance schedules are essential for engine longevity.
