BMW X5 (E70) Drive Belt, Pulleys and Oil Filter housing Gasket replacement (100k miles maintenance)

This is the third video in the 100k mile maintenance series. This video starts with troubleshooting the source of noise from front end, which turned out to be tensioner pulley. Also took the opportunity to replace the gaskets and oil filter and coolant housing as these are prone to fail especially with high mileage and cause potential damage.
If you have the right tools, this is not a very difficult DIY project but you have to be patient and take your time. The hardest part for me was to get the the last air intake manifold nut, and off course the housing bolt that I completely rounded for the lack of ETORX wrench. Do yourself a favor and get the etorex (E10-12) wrench before starting the project. Apart from that, watch couple of other detailed videos on this topic on UA-cam and you should be good to go. Good luck!
