Had a squeaking from the front of the engine and fixed it with the help of the forum, thanks. This is quick supplement to help others:
Symptom:
1) squeak from front of engine, especially when cold
2) may go away on idle, but comes on when driving around 2000+ rpm
Troubleshoot:
1) belt, idlers (smooth). or tensioner pulley (8 line ribbed).
2) in my case it was the tensioner pulley. An easy fix for $25.
Autozone AC Delco idlers $17 ( I bought BilletFlow's for $54 ea.) Autozone tensioner pulley:$25.
FYI
The idlers and tensioner pulleys are bolt-on, not pressed.
