I have a 1989 LXi Coupe with almost 237,000 miles on it. Lately, the engine started making a metallic rattling/knocking sound, and I'm not sure what it could be. I've made a video in hopes you guys can help determine what the problem is.
See the video on youtube here.
Edit: I had my dad take a quick look at my car, and he determined that the pulley on the water pump is starting to fail.
