Loud buzzing after start up

[wendell]

As you may recall, I got in a little fender bender last fall and had the hood, radiator, etc. replaced. Since then, I've been getting a loud buzzing sound about 10 seconds after start up which lasts for about 2-3 seconds.

Since it never did before the accident I'm assuming it is a result of it but have been getting the run around from the shop and insurance.

Any of you experts know what could be causing it?

Not enough information, open up the hood, have someone start the car while you stand on the side (make sure the emergency brake is on) and you should be able to hear where the noise is coming from, this will get you a lot closer to finding out the source...
