Belt Tensioner Spanner Set 21mm 30mm for BMW Mini

A BMW and Mini belt tensioner spanner set for releasing tension on the auxiliary belt system during removal and installation. It includes 21mm and 30mm 12-point wrench sizes to suit the listed engine types and related tensioning arms.

Used when changing a serpentine belt, this set helps when access around the front of the engine is limited and a standard spanner may be awkward to position. It is suited to garage servicing, workshop repairs and home maintenance on BMW and Mini vehicles with EP3, EP6, N12, N14, N16 or N18 engines, especially when working on belt replacement or tensioner-related jobs.

The flat spanner pattern is intended for belt tensioning arms and gives a practical way to move the tensioner during fitting or removal work. With both 21mm and 30mm sizes included, it covers the specified applications without the need to improvise with unsuitable tools. The 12-point drive pattern helps with engagement on the fixing, which is useful when space is tight around the belt run and front-end components. It is also compatible with listed V-ribbed belt tensioning arms including Dayco APV2465, Febi 33136, Gates T39127, INA 534031810, Ruville 55999, SKF VKMA33400 and SNR GA350.67, along with OEM code 116210, helping buyers match the tool to common replacement parts.
