If the outside temperature was about 20 degrees, you would be running

I have been running without a thermostat in my old 38 Plymouth. It gets up
to about 100 degree in cold weather, summer about 170. With the new
thermostat (180), I run at 180 summer, and winter.
Our XJs are designed to run with 195 stats. Running too cold or too hot
for very long will cause many problems later. Seems to me, your problems
are in the fans or fan switchs....good luck....
