Chris,
Radiator Flush used to be a canned product for this job. Nowadays
radiator shops have a "back flush" method of pulsing water backwards
through the entire system, and dislodging debris and deposits. It is a
large machine, not a garden hose fitting. See GOOD radiator shop. Do
NOT "rod" the radiator. In fine tube radiators, the cleaning probe
dislodges debris, but can pack the tube with de-scaled crud, and it will
not flow anymore.
