as I recall, mine CAN go on 2 ways, or so I was told.
Water pump may even spin backwards?
Might have all been an old timer joke since it was my uncle who told me that.
so as I was drawing a diagram on the inner fender with a magic marker,
I bumped my head near a sticker that shows it exactly.
Hopefully a nice big lever will get that spring loaded tensioner out of the way and the belt goes on withOUT your fingers or glove.
