Had a 6 blade clutch fan off air conditioned '62 Galaxie 292 back in the day that fit and worked great but have not been able to find a clutch fan that was not to thick to clear the radiator properly.

It fits OK but I had to trim the fan to clear the shroud. Birds have a lot more "nose room" than the sedans. Will have to hunt for the Hayden part number - will post after I look it up. Hayden part number is 2797 .....got it off ebay (new) for $30 - this is as good as they've got today.... http://www.ebay.com/itm/Hayden-2797-Engine-Cooling-Fan-Clutch-/120894157200?hash=item1c25da7190&item=120894157200&pt=Motors_Car_Truck_Parts_Accessories&vxp=mtr Steve Metzger Tucson, Arizona

So this is as simple a swap as it sounds....bolt out and bolt in, and you're good to go? I'm really glad this thread was started....I've been thinking about doing this for a while, but especially recently with the kinda' abnormally hot weather we're having in Syracuse (94 today!) I've become more serious about it. Questions: 1) does so simply a change really make a decent difference? 2) why not the flex fans? Thanks guys!

I was planning a 190F stat and a 10 psi cap. What are you using and what does it take for your clutch to engage fully (or does it?)

But.....they don't publish a temp versus engagement curve. I'd like to see it anyway... I put the smaller diameter 289/302 sized pulley on my water pump - 180° high flow thermostat - and the fan noise went way up (had a six blade fixed pitch fan on there). The temperature did what I'd hoped - which was narrow the operating range - low end up to 180° and upper came down a bit. The smaller pulley was spinning the pump about 11% "overdrive" compared to stock. Finally decided that while the extra pump flow was good - I'd like to lower the fan rev's - and the clutch looked like the best way to go about it. The advertised "hot" 80%/90% drive speed got the fan back down to where it was before anyway. That was still using a six blade fan - when I found the seven blade, greed set in and I had to hang another piece of aluminum in there - what can I say. At hot idle it engages and whizes right along - fan is in the right spot in the shroud and all of those blades give good account of themselves. On the road - I don't know what happens - I'm pretty deef from all of the years in excavators, so any change in sound at speed is lost on me. The car seems to like it - but if it freed any power - the pump is probably using it! Steve Metzger Tucson, Arizona

Thanks for that! I have a clutch fan on my 6.5L diesel Suburban and it's disengaged most of the time. If I'm pulling my boat up a hill long enough to get it "hot", the fan engages and you can REALLY hear it! Similarly, when it disengages, it's just as obvious. I'm hoping that it'll work about the same. I was going to install a Flex-A-Lite dual fan 4600CFM system but I was a little worried about that because they have a GVW max for them. (They use the 6000CFM model for HD use, motor homes, 3/4T trucks ETC) The fan that I have has (2) more and larger blades than original and the radiator is a 4 row instead of the original 3 row so I don't expect it to be a problem but the clutch is sort of an unknown....... ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- 1955 F-600/272/E4OD// Disclaimer: No animals were injured while test driving my F-600 except the ones I ran over intentionally! --------------------- This post was created using OpenSuSE Linux x64 and Firefox
