AC noise

I just had my radiator and fan clutch replaced, and now when I'm at a drive thru I've noticed a rattling noise when the AC is engaged, engine runs smooth and quiet when it's turned off though.

Any suggestions?

Best

Rick

Check the belts and tensioners. Could be the issue.

I'll do that. Thanks for the advice on the last issue, you were correct they did more than just replace the radiator, as well as the rest of the post.

I don't have a trusted BMW mechanic in town but I do have experience and rapport with a mechanic that works on Japanese and American cars, think he could at least diagnose the problem?

I have also ordered the manual, is this something that I could look at myself? My knowledge and comfort level workin on a bmw is basic but I'm looking to expand it. I've worked on American vehicles, some solo and tougher tasks with assistance, like a brake job, is this a reasonable starting point or would this be outside of a oil change skill level.

thank you

Rick

Personally, i do all the work on my car myself. From oil changes, to shock replacing, to brake services. However, i dont mess around with the AC system. The compressor is under pressure and the refrigerant used is R134A, which is oxygen depleting. A massive leak in a confined area can kill you. Having worked in a room with computer servers with the fire supression system using oxyen depleting materials has kind of drilled it into my head not to mess around with that stuff.

However diagnosing a rattle shouldnt be that difficult. If the sound isnt their until you turn the AC on, start by checking the belts and tensioners. Try listening to the compressor when it turns on,
