Craig, Are you talking about the over flow tank in the engine compartment not the radiator. Normally if you get coolant that backed out of the over flow tank tube to the ground it's thermostat. If that hasn't been replaced in a long time then I would try it first and then move on to the radiator. I wouldn't waste my time or money in trying to clean out the original old one if you still have it. Be careful about some vendors trying to sell a rebuilt 25 year old 2 row rebuilt as new. They had brass end tanks put on them an call them new.
