2007 Dodge Caliber SXT w/2.0 liter engine. Recording was done in my garage with a cold engine.

0:00 — Engine just started.
0:00-0:28 — Moving mic around front and front-passenger side of car to hear noise from different angles.
0:28 — Opening the hood.
0:28-0:43 — Holding mic above passenger side of engine (where drive belts are).

At 0:43 I accidentally paused the recording, then unpaused it a few seconds later.

0:58 — Engine revs, chirping disappears at higher RPM.
