My XC90 has a noticeably squeaky belt noted usually upon the inital start-up in the morning, especially noticeable with the a/c compressor on. It appears to be coming from the smaller accessory belt that notably was replaced a couple of months ago during a thermostat and timing belt repair by the dealership.
The tensioner by all appearances and feel seems to be holding good tension on the belt, i.e. the belt doesn't say very much when pushing on it with my thumb. However the squeal is getting worse. So my question is....
How do I remedy this issue? I am aware of the T60 torx driver trick to manipulate the tensioner without the special tool, but it doesn't seem to be "loose" or need to be rotated any at the tensioner.
Thanks in advance for your input and assistance!
