it locked up on me. Im lucky I had a spare one just sittin in my basement but it was old one from my other motor. This one is going bad though some days its louder than buses riding past and somedays you wouldnt even kmow it was messed up. I just need something for right now. Im not trying to put no more money on the motor because my other motor almost done with the rebuild,im just wai rting on heads and lim porting to be finished. Not tryin to pay for another ac compressor cost to much and I barely use my ac anyway
