After I noted that the aux fan had been coming on, we opened up the hood up and he just grabbed the fan while it was running, felt for resistance, and made the diagnosis. As soon as I noted the aux fan was kicking in he said this happens when the rad fan is not cooling the engine sufficiently. I guess I will check it myself. The coolant temp needle never gets beyond 12 o'clock so it does not seem like this is a pressing issue, but if there are other things to check, let me know.

He didn't say exactly what the update would do. He wasn't pushing me to do it. He said sometimes it will fix small engine/performance issues, presumably like them one I am having.
