On very cold mornings my car will make a grinding noise while I wait for it to warm up. I have a 2004 GT with no mods. I believe it’s coming from the right hand side of the engine bay. I don’t think it’s an engine issue and doesn’t happen at start up. I can make it happen if I rev the engine and hold it at 3k rpm’s on very cold mornings. This noise doesn’t happen once the car is warm and doesn’t happen any other time other then on cold mornings while I wait for the car to defrost. Any thoughts? I hope the video link works.
