Hi. I am looking at a 1978 240D. Appears to be in pretty good shape, though the owner, whose had it only for a year, claims to have never had a valve adjustment. I thought that was the first thing you do when you take on one of these?

Anyway, the main issue is the AC, which they claim works and blows ice cold. Or, I should say, worked, before "the belt broke." [Edit - they also have said the compressor "works great".] Is there anyway to confirm that the AC works, blow cold, etc, without a belt being installed?

I realize getting a belt on is an inexpensive job, but it would be at my expense to confirm the AC actually works. And of course, would be quite expensive to get the AC up and running if it has the usual servo problems.
