Together, we're a team (alone we're nothing) ...
For the record, many people (including me at first) are confused whether to twist on the mechanical tensioner pulley centerbolt or to leverage on the raised knob (or sunken Torx in the 2003 E39) on the side of the tensioner.
To make matters worse, folks with the hydraulic pulleys often unintentionally mislead we mechanical tensioner people by talking about the pulley Torx centerbolt (which, unless you're replacing 'just' the pulley, which most of us do not do, then it buys you nothing to loosen the pulley centerbolt on the mechanical tensioner).
Anyway, the topic came up, again today, over here:
- Serpentine Belt Replacement
To which WagonTheDog posted a wonderfully succinct picture that I reproduce here for all to benefit:
