I finally decided to replace the squealing belt tensioner on my 200 (the same problem there was a TSB for where it squeals for a few minutes only when cold and then stops). It's more of an annoyance than a serious problem so I've put it off for a while but I'd still like to get it done. If you've taken a look at where the tensioner on the 3.6L engine is on this car it's very close to the frame rail so getting a normal socket on the bolt isn't possible with the limited clearance. Does anyone have any tips on how to remove the tensioner bolt? Maybe the right wrench could fit in there though with the bolt head recessed into the tensioner it would have to be on some kind of angle. Thanks for any suggestions you might have.
