Why am I better off with the 180? I'm not pulling heavy in the summer and my temps aren't that high anyway. Also, I've got little or no heat :{ , radiator completely covered and it barely hits 180-190 with 760lbs in bed and snowblade on the front running 65mph. Ya think my old t-stat is just bad?
I'm not opposed to running a 190 in the winter, and changing to a 180 in the summer, looks like a 10 minute job. Or do I even need to mess with it every year?
