Squeaking noise from engine compartment. Some 2005-08 Avalons, 2006-08 RAV4s, 2007-08 Camrys and Siennas and 2008 Highlanders (all with the 2GR-FE 3.5L V6) may emit an annoying squeaking sound from the engine bay when the engine is idling. One likely source of the noise, says Toyota, is a worn No. 2 idler pulley. Replacing it with a more rugged design (Part No. 16604-0P011) and adding an extra pulley cover plate (Part No. 16649-31020) should silence the noise in short order.
In the illustration at right, notice that there are two No. 2 idler pulleys shown. Avalon, Camry and Sienna models use both, so you’ll have to double up when you order the new-design pulley. RAV4 and Highlander models have electric power steering, so they use just one No. 2 idler pulley—the one on the lower right in the illustration.
