  1. OK, I give up. I haven't been able to find a quiet mechanical replacement fan for my stock 5 blade Avanti fan. I've decided to go with an electric fan. Someone has surely installed an electric fan on a 63-64 Avanti, if so do you have a brand and part #. Only interested in a single fan puller type that will fit between the front hub and radiator. Thanks. Larry
  2. Thanks, appreciate that information. Larry
  3. Thanks, I saw that and that is why I was trying to confirm that was the correct part number.
  4. Should have clarified - "A/C" fan speed switch. Thanks
  5. What is the part number for 63 Avanti fan speed switch, thanks.
  6. Are you interested in selling the 7 blade #1560547, assuming it's for a 63-64 Avanti.
  7. I'm starting a new thread in my never ending quest for a quieter fan for my 63 Avanti. I was advised there was a H.D. 7 blade fan, #1560547 available. A quick search and I haven't been able to locate one. Does anybody now where I can get 7 blade #1560547 fan. Thanks.
  8. My original fan clutch checked out fine but I replaced it with a new one anyway and the noise was the same in both instances. I haven't tried another fan blade yet, haven't found one that will fit. The stock one has no cracks and checks out straight and true when I checked it on a metal lathe with a homemade adapter. I think the fan design is flawed from a noise standpoint, particularly with the other reports of fan noise with the stock five blade fan. This brings me back to my original question - has anyone found another fan choice that is quieter. I'm not at all familiar with a 7 blade
  9. Interesting thought but I have two Corvettes with clutch fans and do not experience that same roar I get in the Avanti, not even close. Perhaps a little measuring is in order, they don't eyeball as a fit, look larger. As I mentioned the kicker with the Avanti is the close fit between the front hub and the radiator. I guess I'm getting lazy in my old age and looking for an answer that will save me a lot of work. I've already tried a few different fan combinations that looked good but didn't work, the swapping around is getting old. There have been several reports that the HD six blade fan
  10. All the above information is interesting but I would still like to know specifics of anyone using a quieter fan blade on a 63-64 Studebaker Avanti. We have all owned old cars with clutch fans that were pretty quiet, sure would be nice to know of one of those fans that would fit. I just thought someone may have tried another fan that filled the bill. As a last resort I will go with an electric fan but hate to have to upgrade the alternator plus as a puller there are fitment issues here as well.
  11. Thanks for the heads up on the pulley. I do have the 2 row aluminum. I will pay more attention to the noise vs rpm. But since the noise seems to be there at most rpms once it kicks in I'm not sure that's the answer as the noise, albeit lower, remains at lower speeds. Before it kicks in there is virtually no discernible fan noise. Since lower rpms would accomplish the same thing as the standard pulley (lower the fan speed) I think it would be a marginal gain at best. I think for now I would like to pursue the flex fan route but as I mentioned the 17" Flex A Lite hits the lower hub so I co
  12. Thanks for info Jack. I tried fitting a flexible blade stainless steel fan only to find the curve in the blade was so severe it hit the front hub (17", 7 blade, Flex A Lite). I suppose I could try a 16" (I worry about a 16" cooling properly) or cut a notch in the 17" blades. Which brand and size blade did you use and was it quieter and did it cool ok.. My stock setup cools fine it's just NOISY. I'm trying to stay away from an electric setup, the old prestolite wouldn't cut it, particularly with the A/C on.
  13. I want to revisit this subject since it's been awhile since I've looked into this. The radiator fan noise on my 63 Avanti is very aggravating, when the temp approaches 180 the clutch starts kicking in and sounds like a dive bomber. It's not the clutch. Anyone know of an alternate fan choice that is quieter. In the past I've read of many other complaints about the same thing and thought somebody may have come up with a solution. Thanks, Larry
