Description

Keep the serpentine accessory belt tracking true and running quiet with the Four Seasons Accessory Drive Belt Idler Pulley 45919. This smooth back-side idler drops in on the 2005-2007 Cadillac CTS (V6-2.8L), 2004-2009 Cadillac CTS (V6-3.6L), 2009 Cadillac SRX (V6-3.6L), and 2005-2011 Cadillac STS (V6-3.6L), where it guides the belt across the power steering and air conditioning drive.

Steel and thermoplastic construction: built for longer life and improved dampening.
High-grade bearings: made to withstand higher operating temperatures.
Smooth (non-grooved) pulley face: 2.750 in / 69.85 mm outside diameter for a 1.125 in belt.
Mounting hardware included.

As a back-side idler, it rides on the flat back of the accessory belt to route it and help maintain proper tension; it does not drive an accessory itself. Signs the original may need replacing include bearing noise such as a whine or growl, belt squeal, or a visible wobble as the pulley spins. Diagnose the source of any noise before replacing, since a belt or another pulley can produce similar symptoms.
