I need help figuring out 2 different noises coming from under the hood.
1. When start, there is a squeal noise similar to when there is a bad belt or idler pully on old cars. After just a few seconds or if I rev it up a little the noise goes away. The alternator was replaced a few months ago. The belt looks fine, and honestly does not feel very tight. Should I tighten or loosen it?
2. There is a metallic (valve sounding) rattle during acceleration; it stops during cruise. I've noticed it getting a bit louder. The sound is like what I remember an engine doing when the timing was off (We're going back to 1970+. At that time manually adjusting the timing by turning the distributor cap would make that noise.
Thoughts?
