Cummins 4089202 Cooling System Gasket Kit

The Cummins 4089202 cooling system gasket kit is engineered to seal critical interfaces within the charge air cooling and engine coolant circuits of QSK series heavy-duty diesel engines. The kit comprises multi-layer steel, graphite, and high-temperature elastomer (MP15) gaskets designed to withstand elevated boost pressures and thermal cycling inherent in mining, marine, and power generation applications. Component construction utilizes Interface Materials technology to ensure conformability on flange surfaces and long-term resistance to coolant additives and oxidation. The kit addresses the aftercooler core, water pump mounting, thermostat housing, intake manifold, and cylinder head coolant passages. It serves as a consolidated service package for overhaul or component replacement procedures. OEM cross-reference includes Cummins part numbers 4089200, 4089201, and 4086225 associated with the QSK60 platform. The kit is validated for Cummins QSK45, QSK60, QSK95, and QSK45 CM500 engine configurations. Net weight is approximately 2.5 kg. Package dimensions are 115 cm x 50 cm x 12 cm.
