Fault Example: Komatsu PC400-6 (6D125 Engine) Overheating Issue
Processing Solution: If the engine is overheating, inspect the Lower Water Pipe 208-03-61190 for internal collapse or external leaks, as this restricts coolant flow from the radiator. Also, check the radiator fins for blockage and verify the thermostat function. Immediate replacement of the hose is necessary if it shows signs of deterioration.
Preventative Maintenance Tip:
Routine Engine Oil Analysis for Cummins QSB6.7: Regularly collecting oil samples and analyzing them can detect the presence of metal wear particles, coolant (glycol), or fuel dilution early, preventing catastrophic component failures in the Cylinder Block or Engine Bearing before visible symptoms appear.
