Does anyone know what the simpleFunction is for coolant temperature? "watertemp":{"simpleFunction":"watertemp", "off":"invis", "on":"decals_gauges"}, does not work.
Actually it should work and 'watertemp' is the correct name as you can see here (an excerpt from the electrics.lua): Please make sure that the first string must coincidence with the material you gave the corresponding mesh. Furthermore you need to have this material in your materials.cs file. Check out THIS and THIS wiki article for more information.
