Anything that secured the tensioner arm to the block got 24 NM (23.96 on my stupid torque wrench). If it's an M8 going into the OFH securing the idler, 40 NM should work. If you feel that's too high start off at 33 and if that feels like you're moving too much metal leave it there.
cool, thanks. just for posterity, here's what's behind that link (and is the only reference i found to the tensioner or idler)
