2010 Civic Noise Near Engine


New Member
I have this noise (grinding noise near engine) whenever it is cold morning. I went to a local mechanic a few times. They didn't know.
I have attached two videos took from front and one from inside. Could anybody help me what is the problem with my car?
(In the summer, I had belt tensioner replaced from the same mechanic I went for checking this noise)

Wouldn’t really say anything is grinding. Sounds like it’s coming around the alternator. Have you run any cleaners? Recommend Lucas engine cleaner could just be knocking from dirty pistons
