Re: How hot is too hot?
I had similar issues, and went to a 165 thermostat as a result. This spring I've been running right at that 165 mark (hwy and all), but once the summer hits, I know I'll be in the 180-200 ballpark again.
I think that 210 is OK, but starting to get out of the "comfort zone", especially if running long periods of time at that temp...if you hit 220, shut her down!
