Does anyone have a drawing\picture diagram of a 3.8L GM V6 engine? I think I'm missing some pulleys (water pump pulley is one of them) but I think I'm missing another pulley that goes underneath the alternator. I'm not sure what that pulley is used for (it seems to be a "idle" pulley according to crowley marine diagram but my bolt seems to be welded in. It would be so much simpler if the SELOC manual had an exploded view diagram of a 3.8L engine so I can tell what missing parts I have to replace. Would anyone happen to have one that they can post up? Or tell me what my "missing part is?

Motor model number is 384STMRCRJ.

Thanks!

it's the tensioner for the water pump belt on models that don't have power steering.
If you have p/s, the pump tensions the belt.

parts book with all drawings is online at epc.brp.com
