How hot am I actually running?

Well, I'm sort of at a quandary. I finally hooked up my autometer gauges, that I have had mounted in my jeep for over a year. But now I am wondering how hot I am actually running. My autometer gauge says I'm running around 150-160 degrees Fahrenheit , when my flexalite fans kick on. However, my Jeep's gauge, reads ~80-90 degree's Celsius. However, the factory gauge is reading off the autometer sending unit, so the calibration is probably not in synch.

Now, I don't think my Jeep is getting as hot as it used to. (mind you this is pretty much a toy, and gets driven maybe once a month) However, it still seems like it is pretty warm, possibly warmer then 150-160*F.

I am just wondering if anyone has run into a problem with the accuracy of an autometer gauge.

Are you taking the readings from the same place?

As Karl said, are your senders getting the same input? They cant be stacked in a tee fitting or something and get the same readings. Im not saying you did it wrong but I have seen senders too far away to be accurate. Apples and apples/oranges and oranges

They are both reading out of the stock location with a new sender.
