Question: 04 bmw x5 3.0 engine how does the alternator belt tensioner release ? YesA Shopper / Jan 26, 2021
Hi, This part is guaranteed to fit the 2004 BMW X5 3.0i 6 Cyl 3.0L 24 Valves, Manufacture Body Code Name: E39. To loosen an Alternator belt tensioner, loosen the main mounting bolt, usually on the engine, and the locking bolt, usually on a bracket or arm. If equipped with a tensioner screw, back off the tensioner screw. Then, push the alternator toward the other pulleys, loosening the belt.

There is a hex key bolt that you rotate to relieve belt tension.
