Often sound echos around under the hood making it difficult to pin-point the source.

Marc Haibeck showed me a trick using a mechanic's stethoscope to find a the source of a squeal. He removed the diaphragm and steel probe section from the rubber tubing and just used the open tubing to poke around the various pulleys, etc.

In my case, it was the water pump. (The embarrassing part was that I earlier had convinced myself it was the power steering pump and had already replaced it...only to have the squeak return as before!)
