1997 Pontiac Grand Prix Removing idler pulley

If it is an idler pulley it should have a bolt in the center of it. The tensioner pulley , you will probably have to remove the entire tensioner. Is this a 3.1 or a 3.8 liter engine?

It is the idler pulley. There is a hole in the center. I can't make out whether it is a torx, alllen if anything. The engine is a 3.8 liter.

Thanks,

P.S. I'm not a complete novice. I've probably replaced 5 or 6 water pumps over the years. I've even replaced timing belts.

Has to bolt on somehow, most likely a Torx, GM doesnt use many Allen bolts. Might even have a plastic cover over the center of it.

Not much help. I'm back at square one.

Has to bolt on somehow............ No software will tell what kind of bolts are used or how to remove some parts off an engine, they just assume that some things are abvious, so they dont go into details on how to remove them

Ok from square one I looked it over again. I was wrong in my description. It's the power steering pump. How do I get it out of the way?

Removal of that pulley requires a special puller as well as an installer to get it back on. You should be able to access the mounting bolts for the pump through the holes in the pulley and just unbolt it and move it out of the way
