Thanks for the pic. I did successfully get the belt off and back on again, although the area is rather confined with MANY sharp edges as my arms can attest. lol Thanks again for the help. This site rocks!

I replaced the serpentine belt but it is extremely tight and I fear ruining something, is there an adjuster on the alternator or anywhere else?

The belt tensioner is solely responsible for holding the proper amount of tension on the belt. So this means I think you need to look at two things. First check the tension on the tensioner. Are you able to move the tensioner or is it so tight that there is no travel on the tensioner?

If not then you need to check the length of the belt. I attached the OEM part number just for you to cross reference the one that you have. I suspect it may be too short if it is in fact too tight.

Let me know if you have questions or what you find with this info. Thanks

After running it and shutting it down the new belt seemed to relax, I pulled it off and back on easily, the tensioner does have a bit of play just not as much as the old belt hence the reason to change it. It's all good now. I even called the store where I bought it just to check the product number which were correct so I'm good and thank you very much for your professional advice and quick response.

Awesome. Thanks for the update. I did forget to mention that the belt will relax after it heats up a couple times. Glad you brought that up. I am sure that info will help others that visit this site with this issue. Thanks again. Please come back to 2CarPros in the future.
