Q: How to remove and install a solenoid on Jeep Wrangler?
A: The procedure applies to 1993 and earlier models only. On 1994 and later models, the solenoid is not serviceable; if it fails, the starter must be replaced. Disconnect the cable from the negative terminal of the battery. For all solenoids except Motorcraft, remove the Starter Motor. Disconnect the strap from the solenoid to the starter motor terminal. Before removing the solenoid from the starter motor, detach the starter motor terminal strap - Mitsubishi starter shown. Remove the screws which secure the solenoid to the starter motor. To detach the solenoid from the starter motor, remove the solenoid attaching screws from the front of the starter solenoid mount - Bosch starters only have one screw. On some models it may be necessary to twist the solenoid in a clockwise direction to disengage the flange from the starter body. Installation is the reverse of removal. For Motorcraft solenoid, locate the solenoid- it's mounted in the engine compartment near the battery. If you have a Motorcraft starter solenoid, it's located near the battery- to remove it, detach the wires and remove the mounting bracket bolts - be sure the battery is disconnected! Detach the electrical wires from the starter solenoid terminals. Label them to assure proper reassembly. Remove the solenoid mounting bracket bolts and detach the solenoid. Installation is the reverse of removal.
