For the record, a side discussion of which tensioners are adjustable went on today over here ...

When the 13mm bolt is loosened (it's the one that goes thru the slotted part that allows for movement to loosen or tighten) place a 17mm socket or wrench on the 17mm bolt (on the right) and turn/push it counter clocwise. This puts tension on the belt/pulley...while turning/pushing the wrench on this 17mm tighten the 13mm bolt preferably with a socket wrench.

This is how you put tension on the pulley for the V8. For those that have the it the same type of set-up?

(#8 = the 13mm bolt & #9 = the 17mm bolt in the image above)
