Gates 09-12 Audi A4 4-Cyl. 2.0L Idler Belt Drive Pulley

This is the Gates idler belt drive pulley for your 2009-2012 Audi A4 with the 2.0L 4-cylinder engine. The idler pulley is a key part of your accessory drive system, guiding the serpentine belt and keeping it tensioned correctly. When it starts to wear out, you might notice noise from the front of the engine, or the belt might not track properly.

Gates makes this pulley to meet the original equipment specifications for your Audi. It's built with durable materials to handle the constant rotation and tension from the serpentine belt. A well-made idler pulley ensures your belt runs smoothly, which is important for keeping your alternator, power steering pump, and A/C compressor working as they should. Replacing a worn idler pulley is a straightforward job that can prevent premature belt wear and potential drive system failure.
