Clutch fan possible?
I tried the Hayden 2947, after I moved the radiator forward. It didn’t engage, so I tried the Hayden 2765, it would engage either at 220*. So I put on a Derale dual fan set up, works awesome!
Now I might of gotten 2 bad clutches from the get go, but neither would do low speed or idle cooling necessary for my 470. Hopefully you have better luck and don’t forget to use a shroud.
