I have read through a lot of threads on this. I have an 02 and in the cold weather, started hearing a squeal. Sounds like a baby cat is stuck in the engine bay MEEEEOOWWWWING.
Using only ears, the sound seems to be loudest a the AC pulley/belt.
I need to know in simple terms how to tighten/quiet the belt. I don't use the AC and it's 15 degrees right now anyway, so AC function isn't paramount. I just don't want the cats in neighborhood chasing my car anymore.
