Re: Mechanical fan clutch ID

I just went back to a clutch fan as well. I used a couple different clutches new from auto zone and carquest. One was a hayden. None of them came on or off at the correct temperature. The hayden stayed locked up fully with the ac on the other I think was a duralast it was still engaged at 184. I got one from a junk yard. Work perfectly. On in town in traffic off on the freeway.
