Thanks for the safety tip, now can we keep it on topic please.

Well you're wrong about the deployment, but I'll go somewhere else.

So ur saying to check the heater & if it blows hot then its the gauge that needs replacing?

Bingo.......or something related to the gauge, sending unit/sensor, electrical connection in the temp gauge circuit, etc.

Gotta make sure the motor has run long enough to reach operating temp to do the heater test. If the heater runs u out, odds r the stat is doing it's job and the gauge is lying to u, when pointing to the 1/4 mark.

Well there's no question that the heat works & works well!!

Put a new stat in anyways & it creeped up to running temp & stayed there so signs look good, but have yet to road test it.

Noticed something odd tho, after shutting the jeep off I saw the clutch fan still spinning. So when it stopped I was able to spin it by hand easily. Its not wobbly type of loose, it just spins freely. SO is this normal?????????????
