BMW Z4/E85 Water Pump Replacement DIY M54 Engine Belts & Pulleys Guide (part 2)

New parts and the correct belt tensioner arrive and I take the Z4 for a test drive. I'm replacing these components as preventative maintenance to avoid breakdowns and engine damage. Also, some interesting results weighing expansion tanks from different manufacturers.
