Gary, seen it and fixed it. Sounds like your clutch is on it's way out. It's
also noisy when it's loose.
A lot of folks just take it off and put on an electric fan.
I replaced mine with a good used one.
Take off fan blades then take out water pump (after draining of course).
Drive pump out of clutch - I used a socket as a drift - puller may work too -
don't have one.
Keep little spring clip thing. Mine was like new.
New one is reverse order if you do it.
Also books say to remove radiator. If you get blades off, I found there was
just enough room to get pump/clutch out and in OK.
Don't forget to get a new pump gasket as that probably will need to be replaced
at the time.

Subject: viscous fan coupling
I have several questions about the viscous fan coupling on the later
1500's
What is it's purpose and how does it work?
How do you know if it's not working properly? Mine spins freely when
turned by hand yet I've seen others that would barely make a complete
revolution when hand-spun. Mine also has some lateral play - does this
mean that the tolerance ring is worn/bad? And finally, how do you get it
off there - 2 or 3 jaw puller?
Thanks in advance for the wisdom.
