KOMATSU-4D95-6D95-THERMOSTAT

600-421-6120 is the thermostat for Komatsu's 4D95 and 6D95 engines, regulating coolant flow to keep the engine within its designed temperature band. These engines are widely used in Komatsu excavators and loaders across mining and construction sites, where dust ingress into the cooling system is a bigger long-term threat to thermostat function than the thermostat's own wear — worth checking the radiator and coolant condition alongside a thermostat replacement.
