Serpentine belt wrenches for Mini models equipped w/ N12, N14, N16 and N18 engines. Each set comes w/ a one large and one small 12-point wrench. If needed, you can use 1/2″ drive ratchet to help w/ indexing the wrench onto the tensioner and for compressing the tensioner back.

There is NO way to determine which tensioner came equipped on the vehicle without physically inspecting the car to see if you need the large or small wrench.
