Hydraulic Belt Tensioner for E9x M3 with S65 engine and E60 M5, E63 M6 with S85 engine. This oil-filled tensioner keeps the main drive belt in the proper tension. Over time, the seals wear, allowing fluid to leak out and the tensioner then becomes frozen or inoperable. Replacement is the best corrective action to take. This can be done during any belt or pulley service or anytime the fan is off the engine.
