With the Febi thermostat in, temps are now usually about 180F, though jumping up to 190F at times (versus 190F-200F), and the max it occasionally will go is about 200F (rather than 203F). It's worth noting the Febi is stamped at 79C (although somehow still 180F) versus the 180F/82C that the Tridon/Motorad Thermostat is, and I've also drilled a 2mm bleed hole in the Febi which may have made it run ever so slightly cooler again.
Pros: runs cooler, stable temperatures
Vehicle:
