lack of care and maintenance in the radiator dept.....how about checking your radiator fluid? checking the radiator itself for leaks, and replacing your thermostat. if this does not work then the problem could be lack of changing the oil....or burning of your transmission check your oil and tranny fluid.....flush the transmission....also if you tow stuff with your tracker you could easily burn out your transmission and that could cause the vehicle to over heat as well.
