The Cummins 3684264 ISX Turbo Coolant Line is a critical component in the cooling system of Cummins ISX engines. This coolant line is specifically designed to transport engine coolant from the water pump to the turbocharger, helping to maintain optimal engine temperature and ensure efficient engine performance.
