Hello gents, I've got to replace the AC compressor on the wife's '98 C280. The compressor seized (the shop tells us) so we got a new one. Shop wanted 1500 clams but parts (compressor and drier) were $500, and I'm looking to DIY. The job does not look difficult but there are accesss issues for my big hands. Three bolts on the compressor, two allen bolts holding the hoses. I have done all my BMW work, but those are older cars without the cramped quarters of the C280; also worked on older MB some with the neighbor.

Have done an hour-plus of searching but nothing seems to come up. With the issues this car has had, I don't think I'm alone.

First question: do I try to get a shop to recover the refrigerant first, rather than simply venting it? I know I'll have to get a shop to evacuate and recharge later.

Second question: not being familiar with this engine and the serpentine belt, where/how do I release tension to get that belt off?

Thanks!
