- Direct OEM Replacement: This drive belt tensioner pulley is a direct fit for BMW OEM part number 11281748131, 11281726343. It is the complete pulley assembly (including bearing and housing) designed to maintain proper serpentine belt tension and alignment.
- Eliminates Belt Noise & Wear: Solves common symptoms of a failing pulley, including high-pitched squealing, chirping, grinding, or whirring noises from the engine bay. Replacing a worn pulley prevents premature belt wear and potential failure of critical accessories like the alternator, water pump, and A/C compressor.
- Wide BMW Compatibility (1991-2008): Fits a broad range of BMW models with inline-6 (L6) engines, including: 3 Series (E36, E46): 325i/is, 328i/is, 330i/ci/xi, M3 5 Series (E34, E39): 525i, 528i, 530i X Series (E53): X5 3.0i, X3 2.5i/3.0i Z Series (E36/7, E85): Z3, Z4
- Hydraulic Tensioner Compatibility: Specifically designed for vehicles equipped with a hydraulic belt tensioner assembly. This is a replacement pulley only (not the entire tensioner arm). The reinforced plastic construction with steel inner sleeve ensures durability under high engine bay temperatures.
- Easy DIY Installation: Standard installation requires basic tools. The pulley is typically secured by a single bolt (commonly a 13mm or 16mm socket). It is highly recommended to replace the serpentine belt concurrently while the system is disassembled for optimal reliability.
