Factory Temp Gauge

Hi george I have had 3 outher 69 Darts in the past 1 had a 318 anouther 360 and 3rd had 273 all had some high performance added all with 2 row rad and 190 stat.they all went half way on the gague nothing to worry about.I have e friend in the heating bussiness who once had a probe that we used to see what it was running at and read 195 on my 360.You already know you could get a different gague with readings ,still half way is cool.What always freek me out was when i would shut it down for a few moments and restart it up and the neddel goes all the way to the right but came back once she ran.
