2012 Winnebago Tour 42QD - Overheating
We have been experiencing overheating issues, particularly on hills. We took the coach to a Freightliner service to diagnose the problem. First they said that the thermostat was stuck, preventing the fan from changing speeds. Then, they decided that the radiator needed a thorough pressure washing. When I picked the coach up, they said that it was still heating up and that when I got someplace where I could be without our summer home for a few days, I should have the radiator yanked and dipped. The suggestion was that while it was out, I should change the fan to Winnebago's latest fix. It seems that I am paying for their guessing. Can anyone clue me in on how I should tackle this ongoing issue?
