V-Belt Replacement

From BMW E34 Encyclopedia


V-Belts are critical for proper vehicle operation. You will want to replace the AC compressor belt and inspect your pulleys.


To get proper clearance to tighten the tensioner, put a 17mm socket on the plate followed by a long+flat wrench with a small extension (just enough to not to hit the fan, if you lack space take off the fan).

Put a spark plug socket on top of the wrench with an extension attached to give you more leverage.

From driver side, push the extension forward while using a smaller wrench to tighten up the bolt securing tensioner plate in place.

Torque Specs[edit]

Two 13mm bolts for adjusting pulley/tensioner: 22 Nm
