Q: How to remove and install a solenoid in a starter motor for Pontiac Fiero?
A: The cable should be disconnected from the battery's negative terminal. The Starter motor should be removed. That strap has to be disconnected from the solenoid to the starting motor (M) terminal. The solenoid is then unscrewed from the starter motor using two screws. The solenoid should then be twisted clockwise to disengage its flange from the starter body (Solenoid housing removal is done by twisting it clockwise). Installation includes ensuring that the return spring is on the plunger, then inserting the solenoid body into starter housing and turning its flange so as to engage it in a counterclockwise manner. Last, but not least, put in place two solenoids' screws and connect them with a motor strap.
