Below are my messages from about 2 years ago.  I remember the TriFlow
never did quiet it and I did also try PB Blaster, and then I think
more TriFlow, then gave up.  Still always a bit of squeal and I
resigned myself that I would need to pull the thing apart
eventually.  This summer I thought I had lost the low speed of the
fan but #2 and #3 still worked.  I think what happened is that it
just suddenly got very quiet and I wasn't used to that!  Now that
it's cold I might actually want to use the thing so today I turned it
on low with the engine off and it is working!  It's so quiet I can't
hear it with the engine running.  We'll see how it does this winter
when coldER temps arrive.
