The starter is mounted on the driver's side bottom of the engine.

1. Disconnect the negative battery cable.
   
2. Raise the vehicle and support it safely with jackstands.
   

1. Disconnect the heavy battery cable from the terminal marked B on the starter solenoid (or magnetic switch on later models).
   
2. Disconnect the thinner ignition switch wire from the terminal marked S on the solenoid/magnetic switch.
   
3. On vehicles with automatic transmissions, remove the front starter motor bracket bolts and the bracket. Remove the two starter attaching bolts and remove the starter.
   

1. Support the starter by and hand and position it onto the flywheel housing. Install the two mounting bolts. On 1986-89 RX-7s, torque the bolts to 24-33 ft. lbs. (33-45 Nm). Install the front starter bracket, if removed.
   
2. Connect the starter wiring to the appropriate solenoid or switch terminals. On 1986-89 models, torque the B terminal (battery cable) nut to 8 ft. lbs. (11 Nm).
   
3. Lower the vehicle.
   
4. Connect the negative battery cable.
