There a couple reasons, it is too close and the other is the center of the engine mounted fan would be right at the bottom of the radiator and only a little more than half would work. I could explore modifications of lowering the radiator and moving it forward to allow for an engine fan. I really think the engine has had a malfunction because it ran cool for the first few days. My best guess is a cracked head but I didn't see any evidence while I had it apart over the weekend. My plans are to remove the thermostat this evening and see if it will run cooler.
