On the top of the box there is a nut and a slot in the top of the bolt, loosen the nut and turn the bolt w/ a screwdiver. Adjusting it is somewhat of a pita, being the radiator overflow tank sits right on top. I adjusted mine awhile back, it did help a little. Make sure you hold the screwdriver tight while tightening the nut. The nut locks your adjustment. I still have some play but it is not nearly as bad as it use to be.
