Time to revive this thread.

Question regarding belt tensioners:

For anyone who has done either a full cooling system overhaul or the OFHG job, how do the belt tensioners work? Specifically, I know they have a little cap and that they are a TORX bit set, but I am wondering how much to tighten them when the job is done? I think that loosening them will be very straight forward but is there a "click" or another way to know when to stop tightening or do I need a Torque Wrench, etc

EDIT:

AHH It seems I finally found the information from an earlier post

Water pump tensioner pulley 8mm 10.9 class = 34Nm using 45 torx socket
Deflection pulley 8mm 8.8 bolt = 24Nm using 45 torx socket
