A common issue observed in heavy equipment like the Cummins QSB6.7-powered Hyundai HL780-9 Wheel Loader is sudden engine overheating. The most frequent cause is a failed Water Pump Assembly or a blockage in the cooling system.
Detailed Solution: First, check the coolant level and look for external leaks. If levels are fine, inspect the thermostat for sticking. The most detailed action is testing the flow rate of the Water Pump. If the flow is weak, the impeller is likely corroded or broken, necessitating the installation of a high-quality replacement Water Pump Assembly to restore proper circulation and prevent catastrophic engine damage. Always use genuine-spec coolant for optimal heat transfer.
