Anyone have any experience operating this engine without the AC unit?
Might a shorter rerouted serpentine belt that bypasses the AC unit allow normal engine operation?
Anyone have any other suggestions?

Thanks, Al alp00795
Thanks CorvairGeek for your suggestion about using the Skylark belt. My local Buick dealer no longer carries that belt. Went to my local parts supplier (CAPS) and they were able to come up with it. Cost all of $30. Just installed it this morning and it works great. No longer have that grinding scrapping noise now that the AC is out of the loop.
Saved me big $$$ and gets my Century (190,000 km) back on the road again.
Thanks also to CathedralClub for their suggestions and routing schematic.
Al.

Fortunately I didn't have to go that route. An earlier respondent suggested installing a Skylark 3.3 engine serpentine belt as that model doesn't have AC.. This was done and it worked. Cost me $30 and I was able to do it myself.
Cool, thanks for letting us know how it came out!
