Hey guys,
So it's time to replace the air conditioning in my '87 300e. I used an eBay compressor a few years ago that lasted two summers, shredded itself, and destroyed the system. When I pulled it off, there were metal shards everywhere throughout the hoses. I've been running with a shorter belt and no compressor for a while now. Lesson learned.
I'm going to give it another go with OEM parts. Everything from Aux fan and condenser, to hoses, to evaporator, to relay is going to be treated as junk and replaced.
Is there any reason to use later w124 parts? Should I upgrade to the two fan condenser system? Or just keep it simple and replace it back to factory 1987 spec? Not trying to start another r134a vs r12 refrigerant war

Just in regards to parts, is it worth it to upgrade anything?
Thanks!
Scott
