I've never seen a discussion about whether the fan should be balanced before it is installed in the car. I have a repro 2-blade aluminum fan, but the question is relevant to them all. It would seem that the fan, like all other spinning things (wheels, lawn mower blades, etc) should be balanced so that undo stress is not placed on the water pump. There's even a thread by Tom W over at that other Ford forum that discusses how to balance the distributor rotor. So some questions about this issue arise:
(1) Can we assume the blade is in balance as it comes from the manufacturer?
(2) How would one test the balance of a fan blade?
(3) If, after testing it is found to be out of balance, how would one go about getting it into balance?
My Dad used to have a saying about trivial things: "It ain't a piano ." So, is concern over a balanced fan blade a "piano", or ain't it??
