Belt Tensioner Pulley – 028 145 278E (Febi)

Description

Product Description

The 028145278E Belt Tensioner Pulley by Febi Bilstein is an OE‑quality replacement pulley designed to keep your serpentine/auxiliary drive belt running smoothly, quietly, and properly aligned. Installed on the belt tensioner assembly, the pulley provides a stable running surface and a sealed bearing that supports constant rotation—helping ensure dependable operation of belt‑driven accessories such as the alternator and A/C compressor (depending on vehicle configuration).

Over time, the pulley bearing can wear from heat, mileage, and contamination. A failing bearing can cause chirping or grinding noises, pulley wobble, and uneven belt wear. Replacing the worn pulley with this Febi 028145278E restores smooth rotation, correct belt tracking, and reliable accessory drive performance.
