I was wondering if I could get some help with a problem that I have. Here's my problem: I changed out the alternator on my Roommates 2.4 4 Cyl Stratus and I currently have the new one installed, and I have everything the way it was before I took the other one off, only now I have 2-3 inches of slack on the belt, Thanks in advance for any help that anyone can provide.

Did you route the belt properly? It could also be a bad tensioner.
