Dayco Accessory Drive Belt Idler Pulley P/N:89847
Dayco 89132 accessory drive belt idler pulley for the 2004-2011 Cadillac CTS and other vehicles guides the serpentine belt along its path. An idler pulley drives no accessory itself; it carries and routes the belt around the engine's accessory drive.
A chirp or squeal from the accessory belt, a wobbling pulley or uneven belt wear can mean the idler bearing is wearing out, though the belt or another pulley can make the same noise. With the engine off and cool, look over the belt and the pulley first to find the real cause before you replace anything.
It fits the 2004-2011 Cadillac CTS, the 2006-2009 Cadillac STS V6 3.6L and the 2009 Cadillac SRX V6 3.6L. These cars take one pulley each, and this listing is a single pulley.
