2003 Chrysler PT Cruiser - 2.4L 4 Cylinder Turbo 90,000 mi,
The belt driving the AC & Power Steering has chirped/squeaked for a while. I thought it was the tensioner, so I replaced it with a new one, plus a new belt. Same noise. I then squirted conditioner lightly right at the AC pulley while running, and it went away. Of course within a day it was back. Not crazy loud, but definitely annoying.
