I noticed a weird sound comin from under the hood of my truck today
, Im not sure how to explain it but my buddys 1990 chevy blew a rod and about 6 months before, it was making a simalar sound and it got louder as it went un-fixed since this is my First and only vehicle im Really worried about this because i have no money for another Engine/Truck now im very unsure if its a rod or what... But upon further inspection, I did notice that the Pully that the fan is attatched to is moving back and forth about 1/4-1/2
of an inch.... is this supposed to happen?
and if not could this be the source of the noise?
Please help im concerned about my truck.....
i will try to get a video of the pully so you can see it
