[V8] Coolant Guage wackyness

[Kneale Brownson]

I don't recall specifics, but I seem to remember Keith providing a longish explanation of how the gauge gets the coolant temperature report from a couple different sensors in the coolant system.  Isn't there one on the radiator and another on the back of the passenger side head?  One or both supply the signal to the gauge in the instrument cluster?
