Here is my latest research project. This rattle was intermittent all winter, gone for days or weeks at a time, but back pretty regularly now. I'm thinking possibly AC compressor issue of some sort as if I am at idle in a parking lot the AC will be pretty warm. Once I rev a bit, the AC cools right down or when driving it is fine.
But now with the AC off the rattle will appear every now and then, usually disappearing after 5-10 seconds. Also usually only on at start up. When driving I have not noticed it after leaving the driveway. Like if I run into a store and leave the family in the car, it is not there when I come back out.
Any thoughts?
Edit for confirmed solution: worn tensioner pulley and wrong size belt. Pulley was bottoming out against metallic stops.
