i have a wierd chirp noise from under my hood. i thinks its my belt tensioner, does any one no how to take this off and put a new one on. or is this cover under my warranty?

 

The tensioner is held on by one bolt so its pretty simple. There is a hole through which you can reach the tensioner in the passenger wheel well. It would be easiest to have another person help you, especially with re-installation. Its a bit awkward to push up on the tensioner and get the belt on by yourself.
