If you don't have a drain plug. Remove both radiator hoses, thermostat housing & thermostat, and one heater hose. Open heater tap (If Vacuum remove both hoses) & with low pressure flush heater core till it runs clean. Flush block & radiator till they run clean, fit a new thermostat re fit hoses & replace coolant. Run up to temp with heater open, check for leaks. And if OK you are done.
