I'm getting temps with my scangauge II. I could be wrong, but I was pretty sure the factory thermostat was a 190. Aside from the coolant boiling last year (hasn't this year, replaced the broken rad cap and not much high stress driving) and just higher than normal temps on an engine that never fluctuated much, there aren't any signs of overheating. I just want to get as many miles out of my 270k engine as possible.

I'll post some pics later tonight, but I'm pretty sure I figured out the culprit. I was looking things over and noticed my ac condenser had a lot of junk in it. About 2 years ago on a wheeling trip i went nose down in a mud pit, enough that water and mud got about 2 inches deep in my passenger side floorboard (and rising before I got tugged out). I'm sure just about the entire radiator was under. 15 mins with a garden hose and i had a nice little mud pit underneath my car. Cranked up the truck and within 2 mins it went from 216 to 190. I'll need to take her for a little longer drive, but I'm pretty sure this was my problem. Pretty pissed at myself for not noticing any sooner.
