Description
Description
BMW 11288580360 (also formatted as 11-28-8-580-360) is the OEM part number for a Genuine BMW Mechanical Accessory Drive Belt Tensioner Assembly. This spring-loaded pulley assembly maintains proper tension on a vehicle's serpentine belt to keep engine accessories running smoothly.
Superseded part number. This part directly replaces the older BMW part number 11288570439
Function and Purpose
-
Belt tension. The assembly uses an internal spring and roller pulley to press against the serpentine belt, preventing slack or slippage.
-
Accessory operation. Proper tension allows the belt to reliably drive critical components, including the alternator, water pump, and air conditioning compressor.
- Failure symptoms. A worn tensioner often causes belt squeaking, visible belt bounce, or pulley bearing noise. Replacing the tensioner is typically recommended every 40,000 to 60,000 miles or whenever replacing the drive belt.
