Re: Flex fan
My fan is one that is evenly spaced and I bought it new at O'Reilly's. I 've seen those odd spaced ones before and wondered what the deal was. Quiet is good, although I wouldn't say mine is loud really. When it comes to engine fans though I am leary of getting one with the potential of having a lot of miles on it in case it may be structurally compromised somehow. One thing I was able to do when I got a beefier radiator was to swap my heavy duty 2747 clutch for the standard duty one which did slow the fan a bit and helped the noise. The thing about a short pump 283 is that a single groove pully has a larger diameter than a double and when I had to go with a double, it spun the bleep outta the fan until I went with the standard clutch.
