This answer was rated:

I have a 2006 xc70 with 83000 miles, and when I start the car there is a noise that sounds like a squeeke. It goes away after the car starts, the belt is in great shape, the timing belt is also in great shape. Any ideas? The ac compressor is apparently seized due to rust. But it happens whether the ac is on or not.

wouldn't the tensioner squeak all the time? This is just at startup

No on that model it makes most noise when is cold at start up and as it heats up goes away

I agree but the noise goes away immediately after starting it not when its warm? Still thinking its the tensioner?

That is so to say most common for that noise you describe ! But make sure also is not the compressor for ac
