Better off doing it somewhere low imho
Fair point. I was thinking heat rising and all that so higher would be better. Probably doesn't make much difference in a closed pumped system though.
I have a sensor mounted in the thermostat housing, (on the engine circulation side of the thermostat), and have never seen the temperature go above 90 C. It only gets to 90 C after stopping on a warm day or crawling along in heavy traffic on a hot day. Rest of the time it just stays at close to 80 C.
