As mentioned in the thread title I have a M-Gator with a 3TNV70-XJUV Yanmar. I have been experiencing overheating issues while driving the machine. I cannot seem to get it to overheat while at an idle (No matter how long it sets at an idle). I have checked both radiators for any air flow obstructions, I have ruled out the thermostat by removing it, I have checked the coolant and the oil to make sure that the head gasket hasn't been compromised, I performed a coolant system pressure test to even further test the head gasket and I have used an infrared thermometer to test for "cold spots" throughout both radiators. Both cooling fans kick on and off perfectly and it is obvious that the temp. sensor are working correctly. I am afraid I have ran out of ideas/patience with this issue so I have turned to the Gator Community for some assistance. Any help and/or insight would be much appreciated. Thanks!!
