There are two versions of starter motor the original is a 28100-0Y090 however I fitted the 28100-0Y091 as it appears to be a superseded part and is fitted to the newer models.
Tools required. Referring to head size rather than bolt thread size.
- 10mm spanner/socket.
- Flat blade screwdriver for the starter push connector.
- 14mm socket with extensions and universal joint for the 2 x starter retaining bolts.
- 12mm socket for the starter power cable nut.
- Some patience.
- I disconnected and removed the battery using 10mm socket for battery posts and battery clamps (negative first).
- This allows access to the upper bolt which is 14mm, required Universal Joint and short extension to get to it without having to remove the battery tray and cable harness. Had I in possession an electric ratchet the car battery would not require removal.
- In hindsight, should have just cracked loose the top bolt rather than remove completely. Better to remove this bolt last.
- Jack the car and support on axle stands - did not need to be too high but depends on your body type.
- From underneath remove the starter cable retaining bracket (mounted onto starter motor) held by a short 10mm bolt. Unclip the purple exciter cable (not sure if that is correct term) there is a little mound that requires pushing with screwdriver to release the clip. The red power cable has a cap of the top of the stud connection which in hinged to access the nut so try not to break it, undo nut using 12mm socket and push the cables out the way.
- The bottom retaining bolt is also 14mm easy enough to crack loose then using a stubby ratchet spent a long time removing it, the threads are frustratingly long for some reason.
- Remove the top bolt and the start motor should fall, then manoeuvre out behind the driveshaft.
- Refitting is reverse sequence however make sure the plastic shield in in place from the top of engine. Its like a half moon shape black plastic spacer. I inserted the bottom bolt in loosely and then ensured the sheild and top bolt were back in fully before spending an age getting the bottom bolt back in.
