Main Drive Belt, OEM - F10, F06/F13, F02, G12, G15, E70, F15, F85, E71, F16, F86, G07

Main Drive Belt for N63/N63TU and S63/S63TU engines that drives the power steering, alternator, and water pump. It measures 7 ribs by 1,647mm (7PK1647).

The main drive belt runs the power steering pump, water pump, and alternator on F10 550i, G30 M550i, F06/F13 650i, F02 750i, G12 750i, G15 M850i, E70 X5, F15 X5, F85 X5M, E71 X6, F16 X6, F86 X6M, and G07 X7 models. It's very important not to neglect your drive belts as a failure will leave you stranded. They're easy to inspect during normal maintenance such as an oil change or refilling your washer tank. If there are cracks running across the ribs, sections missing, the edges are frayed, or the threads are visible on the belt surface, the belt should be replaced immediately.

If you can, inspect and test the pulley and tensioner before ordering your belt. Or plan to order new pulleys and tensioner with your belt. The pulleys are made of plastic and shatter with age, causing potentially expansive/expensive damage to your engine, radiator, etc.
