I’ve got a 2003 Tahoe z71 that I’m in the middle of replacing my AC compressor that gave out. While I’m at it I’m also replacing my leaky evaporator in the rear unit. So after some research, I’m finding out it’s really worth replacing the condenser rather than just flushing. I’d like to get the best one out there. There are 2 different AC Delco ones out there. Both claim to be for tahoes with rear AC. One has 864.0 MM Core Width, the other not. The one with 864.0 MM core width is like a $100 more. Is it worth it?
