So there is this squeaking/chirping sound coming from what seems to be under the engine by the firewall area. I've changed the belt and I've used a stethoscope and checked all the components on top area of the engine and no luck . I haven't checked under. Also the sound is there as long as the engine is running. The sound will change as I accelerate or deceleration. The sound stays constant when I'm at idle. If anyone has any idea what this could be please help. I've been dealing with this annoying sound since I got the car. It's gotten slightly louder over time but I'm starting to get worried. I have a sound clip that I tried uploading but I'm getting a message saying the file does not have an allowed extension. Can anyone help me upload a voice recording? Thanks !!
