I appreciate the great responses, however, my question is still unanswered. I have the 216 dampner pulley, the 235 dampner pulley, water pump 216 and alternator. All are 3/8. That is not the concern.
I was wondering if because of the larger diameter of the 235 dampner it will spin the water pump faster, and in turn the fan.
I read hear somewhere that the fan could crack, but again, I'm using a more modern fan as listed above.
Will i ruin the fan, the pump, or cause any damage?
Or, is is better to pull the pulley off the 216 and pound it onto the 235. Thanks all, Phil
