There is a wax-like substance inside the clutch assembly that makes the fan spin. There is no solid mechanical contact between the fan blade and the water pump, just the friction of the shaft spinning in this goo (official technical term). When the clutches get old, this substance leaks out the front of the clutch (rad side) and causes slow fan speeds, and overheat conditions at an idle.
Find the tightest one you can, as long as it isn't seized completely. It would be the best choice. Of course...your local NAPA, could probably find you a new one by proper application. ----------------------------------------------------- To Unsubscribe please visit www.chevelles.net/list.html To start a new topic, send mail to: [EMAIL PROTECTED]
