300E serpentine belt/tensioner replacement
 

Hello, recently purchased a 92 300e and i just started getting a severe squeal from the serpentine belt, and it is so loose you can basically just slide it off. And now I believe the vehicle is losing charge as a result and needs to be jumped occasionally. I've read previous posts about tightening belt tensioner but I think mine may be maxed out, not exactly sure though. Anyone have a link to a tutorial on troubleshooting/replacing the tensioner and belt? I found one pdf. about it on here but the link was dead. Thanks in advance.

Awesome. Thank you so much. Should be tackling this in the next few days. I'll let you know how I make out.

Ok so I finally got around to attempting this today. got through 99% of it no problem. I go to tighten the tensioner adjustment rod and it didnt seem to be making the belt any tighter. also the yellow arrow didnt seem to be moving at all. So I continue to tighten it and it snaps at the bottom where it connects to the steel ring. I am pretty sure it was installed correctly (rod facing the radiator) so I'm not really sure at this point why it happened. I mite do it all over again tom and replace it with the original one. I don't know. kinda frustrating.
