I was trying to replace the belt and I moticed my tentioner was acting up a little. I sprayed WD40 hoping and moved it back and forth, to get it to work properly. I ended up striping the Torx screw on the tentioner pulley.

Any suggestions hot to remove the torx screw? or a DIY to remove the tentioner pulley system. this is the alternator tentioner pulley. I could fine anything in the bentley manual and can't seem to find it here either. I jjust can't see enough to see which bolts to remove.
