    theres a rediculous noise coming from the front passenger side of my motor, it sounds like the fan is hitting the fan shoud, but its not. im thinking it is coming from the a/c compressor, or maybee the thing under that (not sure what it is) anyone have a clue.

    Not sure if you have a serpentine setup of not, if not, you might be talking about the AIR pump, and if its a new one, Ive heard they make some noise till they break in.

    also check your harmonic balancer if your motor mounts are real bad the enging can sag enough to let it hit the engine crossmeber

    i just ran out to check out the harmonic balancer, and i noticed that there is a hole in the thing under the a/c compressor (i think its a vaccum pump?) is that supposed to be there, its a prety clean looking hole...
