Thanks everyone! We will check out the things suggested soon and I'll post our findings. I am really glad to have this resource here!

Take care,
Peace,

Jen, (great name by the way, been married to a "Jen" for 22 years now) I hate to be the bearer of bad news but it is far more likely that you have a harmonic balancer that is spun. The compressor was changed out fairly recently and the belt was probably right and tight then. The "one chirp in the a.m. when starting" is the classic slipping dampner. I hope it is just your belts but it is unlikely. I have sold a ton of dampners on red engines for complaints identical to yours. Volvo list price on that is around 195.00 and you can expect someone to charge you between 1-2 hours to diagnose and replace it. If the hubby has a timing light or access to one tell him to hook it up and shine it on the dampner with the engine running, the timing mark on the dampner for the #1 cylinder should be stationary and visible. If it has slipped the mark will either not be visible (because it is now in the wrong location) or if it is real loose you will see the mark as it goes by which means the inner ring is spinning at a different speed from the outer ring, not good.

Good Luck,
Mark

I agree with John. It sounds like a loose belt. What you do next depends on whether your air compressor work came with a guarantee. Check the receipt from 6 months ago. If covered, then take it back for an inspection of the repair work.

If not covered, then check the belt for tightness. I believe 1/4 to 1/2 inch of play is acceptable.

Best of luck,

Tony

Something with the belt sounds right. Spritz a bit of water on the belts while it is chirping. When it goes away you can tell him you agree with his diagnosis.
