I recently changed my ac/alternator, ps, and timing belts. I was getting squeaky noise before when I turn on AC or start moving from dead stop. Now it’s louder but only from cold start. I am thinking it’s the tension or oil on pulley. But since it’s only from cold start, I am thinking it’s the tension. If oil on belt(s) or pulley(s), I should get the damn noise all the time. What do you guys think? What else do you think it can be? Thanks!
