Original BMW N62N V8 Belt Tensioner Assembly with Pulley, BMW X5 E70 4.8i and xDrive48i (2007–2010)

Built for the E70 X5 with the N62N V8, this Original BMW belt tensioner keeps constant tension on the drive belt of the 2007–2010 X5 4.8i and xDrive48i, and it comes as an assembly with the pulley already in place. Correct tension stops the belt from slipping and keeps the accessories it drives turning at full speed. A belt tensioner uses a spring-loaded arm to press its pulley against the belt, taking up slack as the belt stretches and wears. This assembly weighs 264 g (0.6 lb) and is made in Slovakia.

Original BMW Parts carry a 24-month parts warranty.

BMW names this part simply a belt tensioner, number 11-28-7-546-163, in production since October 2006. BMW's parts data ties it to a single application, the E70 X5 4.8i with the N62N engine, which makes it easy to identify on an X5 V8. Because the pulley is part of the assembly, you do not need to buy a separate idler for the tensioner arm. Some parts houses describe it as an A/C belt tensioner, but BMW lists it as a belt tensioner for the X5 4.8i with the N62N engine.
