ok, so saturday i put on a used compressor i bought from a member here. before i put it in i put about 2oz of PAG oil in it, but have yet to get it recharged, i have put about 40 miles on it, and today on the way to the store i began getting a squeeking noise. i am thinking this noise is coming from the compressor, belt tensioner, or the line that is attached to a bolt either on the compressor or belt tensioner that i did not bolt in, because i could remember where it went. is it anyone's feeling that this is coming from the compressor because there is no pressure or any of the fluid that is put in at a charge (it currently has nothing in it)? or is the compressor bearing going out on it (it was used)? when i put the oil in it the thing spun perfect, and before i put anything in and spun fine as well. as soon as my car cools down i am going to take off the belt and go spin stuff, i was ust hoping someone would have an opinion

 

i fixed it, it was the bolt for the line that i did not clip in at all behind the lower comrpessor bolt.
