Replacing the Gen3 starter motor can be tricky as you have to reach the upper engine side stud. There is limited space and you end up having to get the last nut by feel.
- 15mm open end wrench - engine studs
- 13mm open end wrench - electrical terminals
- 3/8 inch small ratchet
- 6 inch extension
- 6-point 15mm socket
Replacing the Starter Motor
Jack up the rear of the car using the quick jack followed by the floor jack.
Use jack stands and get enough height so you can get under the car to reach up under the motor. Ensure the jack stands are secure before climbing under the car.
Ensure the master switch is off and disconnect the battery.
Come up from bellow the engine to reach the starter motor. Loosen the nuts holding the starter motor on the engine studs using the the 15mm open end wrench.
The last stud which is in upper position closest to the engine block will be difficult to reach. The engine mounts and frame make it difficult to get through from the side and the intake makes it difficult to get through from the top.
Use the small ratchet with an extension and 15mm socket to remove. This can be difficult and will require working by feel.
With the 15mm nuts removed you should now be able to remove the starter motor and lower it down so you can see all the electrical terminals. Note the wire color and positions.
Remove the electrical terminals using a 13mm open end wrench.
Place the new state motor into position on the engine studs and tighten the nuts down with 15mm open end wrench. The difficult to reach stud will require the small ratchet.
Replace the electrical terminals in the correct locations and tighten with the 13mm open end wrench.
Be clear of the car and make sure it is in neutral.
Reconnect the battery, turn on the master and check the test to see the starter works. If the state doesn't work check your electrical connections again. Shut off the car.
Lower the car using the floor jack followed by the quick jack.
