The guy doing my radiator told me about Ultra Sonic cleaning. Usually the larger shops have the process. Its susposed to really loosen and clean out the crud better than anythig. Might be something to ask about for your M-37. I am going to have it done on a original Model A Radiator to be sure its open.
