Hello everyone, last year I did swap on this engine in E30. This year I decided to fix the air conditioning. Could anyone have done it to share what parts he used to mount the compressor? I have the compressor stand on my BMW 39 with a M 52 engine, I mounted it, but it's in the bottom of the radiator hose. I tried to put the compressor from BMW 39 with a M 52 engine, but it literally breaks the bottom hose of the radiator. which are the appropriate stand, compressor and water hose that should be use? Thanks
