Radiator question

Spunk,
There are enough recommendations in this thread to get you started. Report back on your results. You don't need a professional. Get some citric acid powder and clean the whole system as you drive. If that causes leaks to spring, that is good. They were fixin to fail anyway. I haven't read that our engines trap air pockets, but wouldn't hurt to drive the front end up on ramps to help purge any, or try to find a good hill in Ohio.
