Be sure and check that both fans are running. And check when and at what temp they come on. Make sure radiator is clean(wash it out)and no debris is caught in the shroud. I am assuming you dont have screens in shroud openings. And if you ride hard in TX heat and get stuck in traffic, you might get that light to come on at times.You need to get moving as soon as possible to get air flow. I have had this happen before on a certain expressway. I have found if the ground temp gets very hot, heat rises and guess where your radiator gets its air, and w/ the fans running drawing that hot air in also. I also had those screens, and removing them helped a lot. Dont rev engine rpms as much in traffic, let it pull in the tall gears as much as possible w/o lugging. You may need a thermostat MAYBE, I have a 2012 and thermostat is original at 85k. You should have a temp gauge installed.These engines get pretty hot. You may try a coolant additive ICE I believe its called. I put some in before. Cant say if it did anything or very little. I have not had the light come on anymore since I relocated. Good coolant and a clean air filter.And finally do you have an aftermarket tune piggyback module etc. Because it can also be a bad tune, if pipes are installed w/o a tune.
