Fan clutch stuck? The tool I used to fix.

That is how it was acting, as if there was no signal telling it to disengage. I had more than enough pressure built in the system, well over 120 psi according to my gauges. As soon as the direct connect with my shop compressor reached over 90 psi, the clutch popped. All is good now, working as it should.

And that new remote ball valve I installed at the heater core has already paid for itself. I was running early this morning and ran right into a tropical monsoon here in Ohio, LOL. I needed heat to clear the glass, thank God I installed that valve. Right in the construction... It was not pretty.
