    Rated 1 out of 5 by from Nice looking fan but didn't fit any clutch GM OER must have changed the tooling because no clutch would fit in the small diameter hole of the fan. I would suggest taking it off the shelf until it is fixed.

    Rated 1 out of 5 by from nothing fits I went to three parts stores and pulled the fan clutches for all of the listed applications and not a single one would fit this fan. The hole diameter is too small and when I machined my flange on my fan clutch to fit the hole in the fan, the four bolts did not line up and the blades hit the flange reinforcements. Tech suggested a fan clutch for an older impala which I special ordered and it did not work either!! Jegs is amazing but this product needs to be pulled!

    What is the diameter of the center hole and the bolt spacing? I need to verify it will fit the Hayden 2747 fan clutch. Last "OEM" repop I tried had a center hole smaller than the actual stock OEM fan so they fan clutch wouldn't fit.

    Here are the sizes; Center hole 2 3/8" diameter 3" center to center diagonally
