Belt Tensioner

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.

When doing any sort of repair or maintenance there is no replacement for genuine factory parts. Turner Motorsport carries the Genuine BMW brand with pride and has the parts you need to complete your next project with confidence.
