I had a cooling problem several years back that drove me crazy. I had no leaks, no air in the system, a properly working thermostat, and no head gasket problem. In a word or two, the system had all the apperances of being in excellent shape. I decided to pull the original radiator and discovered it to be about 75% blocked. The fins in the AC evaportaor are spaced quite a bit further apart than the original radiator. Junk; dirt, weeds, and even Montana grasshoppers can find their way through the evaporator and lodge in the radiator core. It's practicaly impossible to see this and just as impossible to hose the radiator core out with the evaporator covering the front and the fan shroud covering most of the back. As long as the work was done pulling the radiator I decided to get a three core metal tank radiator from Rob Grady. I remember Rob telling me I may have to make some adjustments in the mounting holes but it fit perfectly. The fins are spaced about the same as the evaporator so there's less chance of the radator core becoming clogged without you knowing it. This solved my cooling problems ever since.
