AC Condenser Replacement

I was looking for AC condenser replacement and didn't find a diy on how to do it. After performing this replacement, I realized that all I had to do was follow beberle's post on radiator replacement:

http://forum.e46fanatics.com/showthr...or+replacement

Prior to following beberle's diy have the refrigerant removed by an authorized servicer in your area (I found somebody to do it for free).

If you follow his procedure up to step 5 you'll be just about finished. It is not necessary to perform step 5 because there's enough room to pull the radiator towards th engine to access the condenser with this hose still connected.

The following steps after that are:

Pull the radiator forward to access the condenser.

Disconnect the AC lines from the condenser with a 6mm allen wrench.

Remove the fastener anchoring the condenser to the frame (located top side opposite end than that of the AC lines that were just disconnected).

Carefully pull upwards and out to remove the condenser from the bracket mounts.

Install in reverse order.

If you're thinking about replacing the ac condenser and either the radiator or the expansion tank go bad, this would be the ideal time to do it.

I don't see any other way of getting to the condeser without removing the expansion tank and pulling the radiator towards the engine to get it out.

Good luck!

What is about the following steps for removing condenser:
1) remove front bumper.
2) if auto transmission or M3: remove A/C aux pusher fan
3) disconnect the condenser
4) remove it through the front of the vehicle. No need to touch the radiator.

I need to replace my condenser also, is it realy possible to remove it through the front? It seems so unlikely when you look at this pic http://images53.fotki.com/v140/photo...MG_7554-vi.jpg

I don't know. I ended up with removal via radiator. Radiator should be removed first, I was unable to slide the condenser out w/o removal of radiator.

In for the info.

I would like to know as well, can the AC condenser be removed without touching the engine cooling system?
