AC Compressor for 89 525/535

[Rodericb]

Quick question. Will the part numbers for an 89 AC compressor for a 525 and 535 the same? I guess the better question would be can I use the AC compressor off of an 89 535 on my 89 525?

check realoem.com to see if its the same part number for both models

BMW used a bunch of differant compressors. Behr, Bosch, Seiki etc. Some are indentical, and some have differances in mounts and manifolds.

The most important things to look for are the manifolds (straight or angled) the side switch if it has one, and the mounting flanges.
