Good point about gauges being off. The one on my 27 reads 20-30 degrees hotter than it really is, the one on Don's T reads about the same off. I shot both with our infared gun and they are running much cooler than the gauges read. I installed one of those Mr Gasket radiator caps on my 27 that has the thermometer in it and that reads in accordance with the infared gun, so I just ignore my dash gauge now as I know it is running cool.

Not sure why my dash gauge reads so far off. I've replaced it with a new one and also a new sender, both read the same amount off.
