What Does the BMW Serpentine Belt Do?
The accessory belt is responsible for transferring engine power from the crankshaft to belt-driven components. On the applicable X5 diesel configuration, the belt routing includes the crankshaft, tensioner, water pump, alternator, idler and power steering.
A properly functioning belt is essential for reliable operation of these accessories. A worn or damaged belt can slip, make noise or eventually break, potentially disabling belt-driven components.
Signs Your BMW Serpentine Belt Needs Replacement
Inspect your BMW accessory belt if you notice:
- Squealing or chirping from the engine bay
- Visible cracks or splitting
- Glazing or shiny areas on the belt
- Frayed or damaged belt edges
- Belt vibration or poor tracking
- Repeated belt slipping
- Accessory-drive noise
- A belt that has become excessively worn with age
When replacing the belt, it is also advisable to inspect the belt tensioner, deflection/idler pulleys and crankshaft pulley for wear.
