I don't know if you saw my earlier thread on this subject, but my gauge was reading 120 until I moved the sender to the front (it was in the back) of the intake. Now it gets up to the correct temp, in fact the other night I forgot to turn on the fan when Don was having his transmission problems, and it went to 220 on the gauge.

I'm going to switch out thermostats on mine when I get back home from Billetproof, mine never gets over 150 going down the road, and the electric fan will cool it down from 180 to 150 at a light. Right now I don't want to tear in to it, but I know 150 is too cool.

Living in Florida, this is sort of a blessing, having a too efficient cooling system, but I know it needs to get around 180 for the sake of the motor and complete combustion.
