Is it on the drivers side or passenger side on the bottom? What engine do you have? Could be a bad bearing in the alternator, ac unit, power steering pump, idler pulley because I don't know what you were touching. I've had alternators make a whining. Could even be a water pump going bad. Take it back to the shop and point the componet out to the tech and tell him it only does it cold. You might have to leave it over night so they can catch it making the noise. If nothing else, take it to autozone and have one of the desk guys come out and you can point to the componet. He will tell you what your looking at. If I was you, I'd buy a Chiltons or Haynes manual at the parts store and study up so you can talk the talk with the repair guy. Good luck.
What is this part called? (re: Engine Whining on Cold Start)

Where is the tensior on this car? 3.6 or 3.2. I have replaced the tensior pulley on every GM I hav ever owned to include My 03 Caddy and My 00 WS6...
By the way nice choice of cars!
IMO those timing belts are good for 80,000 to 100,000 miles, do you hammer on it?
In addition to that the timing belt/chain and all associated componets are under a cover.

The tensioner in this photo is on the passenger side of the motor just above the crank pulley on an arm and second one is right on the other side. Both are on an arm with a 1/2 or 3/8 square ratchet hole in them. This allows you to used a breaker bar to move it to change the belt.
I believe the 3.6 uses a timing chain while the 3.2 uses a belt. As a matter of fact I see no room for a timing belt in this picture. I bet it has chain.
In addition to that is your timing belt is running your altenator. Take it back GM screwed up, on some imports the timing belt will run the water pump.
