I have a temp gauge on the Ruby, definitely not essential but sometimes interesting. Certainly agree with above comments about cooling being perfectly satisfactory. A good radiator core and cleaned out block keep boiling far away. Sevens who joined us on the Cotswolds Tour during the Centenary Week may have has occasional challenges but in general boiling was unusual, although for certain Chummies, bonnet removal up on short but very steep hills was one response. Watching the temperature indicates what a small volume of coolant as the temperature changes rather frequently and quickly. So keep those passages clean and don’t worry!
