You said earlier that you changed the temp switch at the thermostat housing....are you sure your getting a good reading at the gauge? I see yours are not stock but what my gauge reads and what my temp gun reads at the back of the block (which is where that reading is coming from) are always different....just saying you could be chasing the wrong problem

My quandry still exists. The gauge does move as the jeep warms up. Sometimes the jeep will ramp up to 200 deg F on the gauge. As soon as the jeep moves it is back at 160 deg F. I wish there was a way I could confirm we were in open or closed loop. I wish it would flash a code or something.

Read the temp in the radiator like I said. It doesn't matter what the gauge reads. If you see the temp swing.

I put one of these in and it "fail safed" instantly while I was burping the air out of the system. Stuck open permanantly.
