well comming home yesterday from up north i started to hear a whirring noise in the engine bay, i didnt really think of much because the extreme cold.
today it was much warmer (-1) anyways the whirring noise was back. it sounded like a turbo almost......... well i thought at first alternator bearing was going.
later tonight i got a puff of smoke and a buring rubber smell.......................well i open the hood, stuck a flashlight in and wham.. my belt tensioner had completly worn to the metal roller. (its usually plastic) ah man ive never seen this before. my belt could have broken at any moment.
lets just say im lucky.......
has anyone seen a serpentine belt tensioner ever quit?

thats not true, e36's have both spring type and hydraulic. mine was spring type i replaced the whole assemby and the upper idle pully today
I saw one last week at my shop, I pulled the underbelly panel off to inspect the car, and the idler pulley popped onto the ground. And all the car was there for was an oil change! I saved them a tow bill that day.
for sure, when i changed the idler it turned out it was my tension pully that was causing the problem, somehow fried the top idle pully and the tension pully was on its way.
so today i got to learn how to change the belt, tenison pully and idle pully.
