Genuine BMW Hydraulic Belt Tensioner - Water Pump/Alternator Belt - E9X M3, E6X M5 M6

Hydraulic Belt Tensioner for E9x M3 with S65 engine and E60 M5, E63 M6 with S85 engine. This is the oil-filled tensioner that keeps the main drive belt in the proper tension. Over time the piston seals inside allow fluid to leak out. The tensioner 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.
