Hey all, first post.

I recently just came back to school at virginia tech and had to get my
radiator replaced because the guys said it was "busted" and it had
indeed leaked all its antifreeze out.

Anyway, a couple weeks later a muffler hanger broke and i went to a
different place and ended up getting the whole exaust system replaced

So $700 later and a couple weeks after both these incidents when I
drive to classes and only while im accelerating (on hills and on flat
road), a metallic clanking noise occurs somewhere in the front of my
car (almost sounds like the outside of the front, but I cant tell).

It is very noticeable with the windows down and even when they are up
and the music if off. It almost sounds like a clock when im
accelerating at all, "clank.. clank.. clank.. clank", if i drive for
more than say 10 minutes it will shutup but it varies from soft clank
to loud clank.

The weird part is, when i shut off my car after coming back from class
or something (only like a 5 minute drive) it will periodically (every
30 seconds or so) make the ’clank’ several more times even though the
car isnt on or anything.

I went back to the exaust people once and they put a shield around
part of the exaust, thinking it was a vibration, but i told them it
wasnt, but hey, they failed that time, im gonna take it back soon. It
is a distinct clank, like hitting the metal part of a wrench to a
screw driver.

Any thoughts would be extremelly helpful! im no mechanic!
What in a car would be a part that still moved causing a clank after
the car is turned off? (and I don’t think the radiator fan has stayed
on or at least I don’t hear it).

Thanks in advance!
