I work with a 150-5 Komatsu excavator. Had to replace the water pump and now I'm having issues with it getting hot. Have no flow through heater core and pulled bottom heater hose off radiator and have no flow. Any suggestions would be GREATLY appreciated as I'm at my wits end.

didn't by chance leave any plastic plugs or rags shoved in anything or if system was left undone waiting on parts did the critters build a nest in anything and did the unit run hot when the water pump went out the thermostat might have stuck

A little late to reply, but is the water pump air locked? Did you figure out the problem?
