Haven't been on here lately, but i still don't have this thing running cool. I sent my radiator back, and they said there was nothing wrong with it, but talked me into upgrading to a 4 core. Very little difference in temperature. Has anyone had any issues with a Cool Craft Radiator?? Just not sure i am getting a good radiator, thinking about taking it to a radiator shop and pulling the tanks to see if any of the flues were filled up when they built the core? Does that make any kind of sense??
