Thanks to all the good info here, I just replaced my belt tensioner in my 1990 300te. Well, almost done.

Can somebody please tell me ASAP the proper setup for the long nut that goes on the end of the adjustment rod?

DOES THE LARGE FLANGE COLLAR AT THE BOTTOM OF THE NUT GO ABOVE THE BRACKET OR BELOW IT?

The old was below the bracket (I think) but I want to get it right before I reassemble the rest of the engine.
