ok right now once the jeep is at operating temp it runs at 210 which from what I have seen is the norm for the 4.0 but it bugs me. Would like to find a 180 t-stat but the lowest I have found is a 195 from Staut. Was wondering if any knew of were I could pick up a 180 or 185 t-stat at? I have searched the web with no real luck.
