When I bought my car the belt to the compressor was cut the guy I bought the car from said that it needed a new one because it was locked up. So the question is what do I need to replace to make the system work? I have a brand new compressor,dryer,belt, and I heard that when the lines are opened up im going to need some new seals is that it. Will i need to replace the condenser,expansion valve or the expansion valve seal and I looked at the condenser and it looked good.
