Re: Temp Gauge Range
I think they are all different. I bought me a cheap laser thermometer and none of my trucks were exactly the same.

Re: Temp Gauge Range
These guages were never ment to measure temperatures with any accuracy. They are only a reference to show the driver that things are normal or going bad. They are resistance based so any change in voltage or conductivity in the circuit shows up on the gauge. They were designed first and formost to make GM money. Otherwise they would have been mechanical guages.

Mine was running very close the 'H' in traffic once so I pulled over and shot the lazer at the thermostat housing and head. 230. I put water in the rad and quit worrying about it. Checked it later when it close to the middle of the gauge and it was around 185 so at least I know middle and top end temps. O'Reilly $13 sending unit on stock gauge.
