Hi there,

Some radiators do not have drain plugs, to do a complete flush remove a heater hose, lower radiator hose at the radiator and the thermostat housing & thermostat, back flush the heater with low pressure water, then place water hose into heater hose that is connected to the block, flush here, also flush out radiator & flush with hose in thermostat housing, when water runs clean, you are done, replace thermostat and seal/ gasket with new, replace hoses and top up coolant, bleed air and run till normal temp is up, check heater is hot, check for any leaks.
