It might be your camera angle,but is that an incorrect thin stamped Alt. pulley you're running?..That or do you have a standout spacer behind your waterpump pulley?
The correct deepgroove W/P pulley is stamped #3976060 and should not have any spacer behind it.
The correct deepgroove machined Alt.pulley is #1970831 and won't have a number stamped on it but it does stand out 1/4" from the fan surface.
