Before you got the vehicle, what was removed and why was the serpentine belt off? Were they replacing a faulty component?

Make sure the crankshaft pulley was installed properly. They could have installed it backwards and can be easy to do. If it is just remove the crankshaft pulley nut, use a pry bar to pry off the pulley and turn it around. Let me know what you find.

I am having the same problem.I had the tensioner replaced. And have returned to the same shop three times for them to put it back on again. Please tell me what to do or check.
