What is the coolant operating temperature

[BASS-TREBLE]

As mentioned in previous thread, I'm swapping the speedo unit to a digital one.
It has a digital temperature gauge so wandering what the operating temperature is and where the 'red' on the stock one begins?
C or F

160-180 is normal operating temp when it's this cold. Otherwise, the thermostat starts opening up at 172 or 173(the manual says, I can also see it when it does because the temp will shift back down to 160 or lower as the cooler liquid rushes in. The thermostat is at full blast around 208-210 or something, I forget what it says. So basically while cruising you should be between 160 and 185 ish at varying speeds. That's what my normal is, anyway. If I stop or go slow I could hit 200 or so, it doesn't take long, but then you start moving again.

Ohhh yeah, in the summer the fan definetly comes on.

My apologies, the search function didn't want to work when I used it last.
I have found it though, thank you, it's a great help.

Can someone tell me at which temperature the fan kicks in?
I have asked in that thread but someone here may know.
