bought my 90 hatch (d15b2) and the original owner cut all AC lines.but did not take out compressor.i know its possible to take the compressor out and just swap in a shorter alternator belt.anyone know the part number for the smaller belt?
or would i be better off going and getting everything im missing for AC to work properly and put it all back together? ive already got a list of stuff to do already (currently have head in shop,getting new valve seals and a clean up,replacing piston rings,and head gasket,rear struts and coilovers) so im not leaning towards getting the AC back together.

 

Uh...the EF has a separate belt for the AC & alternator. To take the compressor out:

- just loosen the AC belt tensioner (see image)
- remove the belt
- unbolt & remove the compressor
- unbolt & remove the compressor mount w/ tensioner on it

Here's how to loosen the tensioner. You can reach the adjusting bolt through the motor mount brace with a 1/4" rachet + extension + 10mm deep socket:
