Hi,

It sounds like the serpentine belt tensioner is jumping. Check that. Also, I attached your pic below. I circled an area where I see something moving, but I can't orient myself to its location. Let me know what that is.

Take care,

joe

Hello, thanks for the input. Would you know the labor costs for that? Approximately?

Hi,

Please understand that this is a guess based on what I hear. You would need to check it. As far as labor, the manual shows 0.9 hours. So, just under an hour. (See pic below).

Let me know what you find or if I can help.

Take care,

joe
