Champion radiator - I cut her open

I have to agree on the Contour fans. I had tried everything I could think of to try to keep my 499" cool including mechanical and several electric fans even with water wetter. Nothing worked until I followed that link with the Contour fans and Dakota controller. I had to trim the shroud in between fans to clear water pump shaft but overheating problem is finally solved. Thanks to Goldduster 318 for sharing, Joe
