When I got the Yellow Peril, my 73 145E, running at the end of the summer, I got
a lot of noise from the fan. Assuming it was the water pump (fairly low mileage) headed
south. So I replaced it with a new one that I had in my culch heap. Got the SAME noise.
The fan and clutch are aluminum. probably from a 240/B21. I have a couple other fans
and clutches around and conclude that to get rid of the rattling noise I should change
the fan clutch. Other than either installing it and running it (which involves draining
the coolant to pull the radiator) and feeling for slop, is there any easy way to tell
if a fan clutch will be noisy?
