Around town (20-45 mph) I stay at about 80c (170F) still below my 195F thermostat, if I sit at lights for 10 minutes it will creep to 100c and the fans kick on and kick off at 97C. If I cruise down the freeway at 65 mph in 5th gear my smith temp gauge reads 65C with the 195 mr gasket balanced thermostat. In all honesty the difference between the 180F thermostat and 195F thermostat is negligible. The temp sending unit is in the manifold on the drive side of the thermostat housing the fan switch is in the radiator and designed to come on at 197F and off at 188F. It makes sense that I see 100 on my temp gauge when the fans kick on since it is engine coolant temp while the fans are radiator coolant temp. This gives me the impression the gauge is reading correct. maybe not.
