Loud noise in the morning. Is this serious?

When I start my car in the morning there's a loud noise coming from under the hood. Only way I can describe the noise is like if you were to put a paper sheet in a fan. Only happens in the morning for a minute or so.

This is a newer Honda Civic with 70k miles. Only services done on car are oil/filter changes.

Added (1). Not a screech. More like chain rattling. Only happens in morning.

That's how your alternator starts alternating.

A screech? You have a loose belt. It might even be burnt. It needs to be inspected for burning (it's shiny). If it's burned then you should get it changed. If not get it adjusted and tightened.

It could be the water pump at the very beginning. Could be lifter(s) slow to fill up. (Change oil.) Rattling.\ Paper in fan sounds like something hanging near fan.

  • We have a 2006 Honda CBR. When you drive it, there's a loud whirring noise coming the back underneath side. What could cause that noise? The noise is situated around a CV boot on the left underneath side where the differential connects to the middle.
  • Honda Magna VF700C Loud Noise? I have been having this issue with my bike that i just can't get an answer to. I have taken the bike to the mechanic but they would fix the wrong things and could never find what the problem is. My bike makes a loud clanking/grinding noise when the engine is cold but the clanking noise goes away when engine is warm. I have posted a video on youtube to let you see and hear the noise. Please let me know. Thank you.
  • 4 stroke 50cc scooter makes loud buzzing noise at 55 KPH and won't go over 60KPH? I have a fairly new 4 stroke 50cc Honda scooter. I recently put in a new CDI hoping to increase performance. It helped a little bit, but when I go over 55 KPH I start to hear a high pitched buzzing sound and the bike won't go past 60. Even on a flat surface. I'm not sure what the problem is. Does my bike have some kind of limiter? Is it the pulley or muffler? Or is 60 kph the fastest my bike will go?
  • Is a squeaking noise when you let off the brake pedal in your car a serious problem? Whenever I let off the brake pedal in my Honda, I hear a squeak noise. Is this something that likely just needs to be lubricated/cleaned on the brake mechanism, or is it signs of a more serious problem? It is not the brake pads; those have been replaced recently. Is this something I need fixed As soon as possible, (possible brake failure) or is it something that just simple (not serious ) maintenance?
