Yo DennyW you did indeed! I felt in further posts the clutch was getting the short shrift and is tough to test. There is one failure mode that is very tough to test. As in my fan's case the failure was not a failure to engage.... It was a failure to engage fully. My fan always made the appropriate roar when expected. It just was slipping while engaged. So while your test will detect it engaging/disengaging it may not show engaged-slipping. That's why sans some complex dynamic test system it may be easier to just change out the dang thing. For that vehicle, guessin 69 Lincoln, your talking $40.
