    So first time posting on here, but I have a problem. So on my 04 Mini Cooper S I had a coolant leak. So I changed the water pump, water pump flange, o ring to crankshaft position sensor, o ring to oil dipstick tube, and also changed the oil in the supercharger, since I had it out. So I put everything back on and it went smooth until I went to put the belt on and when I release the tension on the belt tensioner it's not tightening the belt there's a whole lot of play in the belt, enough that I can remove it completely from the ac and alternator pulleys.

    So the question is what happened? Is there something I'm missing, also I made sure the hole was clear in the tensioner, the one that holds it in place. There were no issues before I took the supercharger off.

    It's maybe how you ran the belt around the pulley's . Double check it using the below screen shot.

    ^^^^ I keep a printed version in my glove box in case my O.L.D. kicks in. And an extra belt. It looks trivial until you get in a tight space and start that puzzle.

    Also you may want to change the tensioner and idler pulley if this has not been done.

    So it was late when I was working on it last night, so I will check the belt route again, but I'm pretty sure I had it right. Also, I just replaced the idler pulley, maybe 3 months ago.

    Just to verify, so there's no adjustment to the alternator and/or the ac correct? Because besides pulling the supercharger out and taking the bolt out of the tensioner that attaches to the supercharger I didn't mess with anything else belt related.

    When I get to work, after my coffee, if I'm still having issues I'll take a picture and post it so show the route and so y'all can see.

    Well I figured out the belt issue, but now that I have everything put back together, my idle is ridiculously high. Like bouncing between the 1500-2000 rpm range. Any ideas?

    What was the belt issue?

    Plugs, wires or coil.

    It's it out and run it for a little while and let it get warmed up.

    The belt issue was that I was tired/an idiot and was routing the belt the wrong way lol. So I let the car warm up to normal OT because I wanted to get the air out of the coolant hoses still the idle is high. And I didn't have this issue before so it has to be either a gasket or vacuum line. Just have to find which one.

    Yea make sure all the vacuumed lines are connected, also make sure all the electoral connectors are plugged in. I have missed a few a time or two. Last time it was the one on the front of the motor by the intercooler.

    ^ This. Either a sensor or a vacuum line is disconnected.
