pulley tensioner making noise, how I change this?

you could tighten it :p

ps pulley or alternator belt?

There are no tensioner pulleys on a G20. The alternator and PS pump act as the tensioner for those belts. What sort of noise do you have? A loud screech or a slight squeak. When does it happen? (on startup, cold engine, hot engine, under load, revving the engine, etc.)

I've got squealing at start up. Then again, it started after I had my GSpec crank pulley. Summer time not much of an issue, but cold & winter, yikes!

I guess ill have to make a video of it, and its basically all the damn time. I don't really know how to explain it honestly. It was just until it warmed up, not its a constant thing. If the car is under 2k rpm it doesn't make the noise once its warmed up though.

You need to check your belt tension. Also, how old are your belts? Did you ever replace them when you got the car? If they've been squealing this long, and you don't know there age, then I'd consider changing them. With all the squealing going on for this long, the belt surfaces could now be glazed over, and no matter if you properly tension the belt, it will just squeal again. Unfortunately belts are one thing people overlook as something that needs to be replaced as regular maintenance.
