Gates 2017 Mercedes-Benz E300 4-Cyl. 2.0L Idler Belt Drive Pulley

Gates is well-known for making reliable engine components, and this idler belt drive pulley is no exception. If you're working on a 2014-2016 Mercedes-Benz E250, this part is designed to keep your accessory belt system running true. The idler pulley's main job is to guide the serpentine belt and maintain proper tension, which is crucial for all the components driven by that belt, like your alternator, power steering pump, and A/C compressor.

This pulley is built to handle the constant rotation and load it experiences. A worn or seized idler pulley can cause belt noise, premature belt wear, or even cause the belt to slip or break, leading to a loss of power steering or charging system failure. Replacing it with a well-built unit like this Gates pulley ensures your accessory drive system continues to function as intended, keeping those essential systems powered.
