Extremely loud noise and overheating
Hello all! 2010 v6 mustang, bought it used a couple days ago and been loving it. however its currently sitting at the dealership overnight waiting for the morning. Was headed home and sitting at a traffic light with a/c on (yay georgia) when a massive noise started coming from roughly the air intake area. heavy vibrations, rising temperatures and i believe some loss of power but was coasting it to a parking lot at that point so could have been my imagination.
To clarify, not a high pitched whistling noise, or clicking thunking or pinging noise. More of a mini monster roar that could be heard multiple car lengths away. I figured out eventually I could start the car up with all air off and have no noise overheating and power loss, and was able to drive it to the highway and 4 or so exits up with no issue to the closest dealership. the moment a/c is on or started with any air, within 20 seconds its back. Also figured out the original dealership didnt have the air intake fully closed from the presale maintenance. but that was not the cause. No leaks I can see (And I have checked morning and night after each 40 or so minute commute because I don't trust dealerships). Since it was rapidly getting dark (past 730) and I was In a not so safe area (I daily open carry for work for a reason) I decided to not risk trying to repair it with no tools in a parking lot when I have no clue what it is.
My experience with cars ranges from 73 novas to early 2k bulls, This is not a noise I have heard before and i spent hours searching the internet and your forums for any answer before posting. would love any help with this as it's my new daily driver.
And for now Im delaying ordering a new cai and bama tune/exhaust conversion (and more importantly all weather mats) until I have a month of roughly smooth running with this, but it's hard fr me to not mess with cars once I have them.
