I tried a 120* but it wouldnt allow the choke to come off all the way.But then they went to electric chokes.Hmmm OK Brain is shortcircuiting-time for a nap

So you like to know "exactly" what caused the problem for future referance and problems-I like it !edit Oh and I knew you were joking -we could use more of that to keep some of the tension down.

Everyone I've talked to here at home(radiator shop owners,GM tech mechanic,Hayden tech) cautioned me re heavy duty/severe duty clutches versus fan type and fan pitch for those aftermarket clutches....
GM clutch application may just come down to the fan as well...?????

"Valve regulates flow of silicone into coupling (of clutch) from a RESERVE chamber".......blah blah...
This has to do with "torque" of fluid on clutch "coupling" up to rotate fan...I think...
Of course,I'm quoting something I read the other day on how these turkey's work....
