2015 BMW 640i Gran Coupe Belt Tensioner Assemblies

This Litens belt tensioner is supplied by the original equipment (O.E.) tensioner supplier and meets all form, fit, and performance characteristics of the original equipment part. As with the original equipment part, this replacement tensioner is manufactured in Europe and produced for serpentine belt routing applications. This part fits both BMW cars and SUV’s.
