DaveB845,

Before pulling the radiator, I'd suggest a reverse flush using a power flushing tool similar to the following:http://www.tooltopia.com/otc-tools-6043.aspx?utm_source=google&utm_medium=cpc&utm_campaign=paid_search_google_pla&scid=scplp6824371&gclid=CIOsksSx_MUCFcQSHwod9akAew

This tool uses shop air along with water to loosen up deposits and rust. Forcing this water / air stream in the reverse direction as the cooling flow thru the radiator will help dislodge deposits.

A radiator cleaning solution would be my next suggestion, in addition to the reverse flush. Prestone has a decent one available at most Auto stores, or Oxalic acid can be used as long as you follow up with a neutralizing agent.

Finding someone who knows how to properly repair a honeycomb radiator is not easy. The Brassworks and Topsham Radiator are two that come to mind.

Hope this helps you out.

Dave
