82 245 gl 157,000 miles k-jet no AMM. Ok drove the car from work down to my local papa murpheys pizza place, the temp gauge stayed in its normal place just like usual. I went in and was out of the car for about 10 minutes, I got my pizza and came out and was on the phone so I just turned the key to the on position and finished my phone conversation when I looked at my dash the temp gauge was at about 3/4 of the way up the gauge (Note the car was not started). When I started the car the gauge came back down below the middle where it usually sits. What caused this I have never noticed this before but I never really sit there for to long with my key in the on position either. Is this just a sign that the gauge is working?
