How to Replace a Starter on a Ford F150by Chris MooreUpdated July 05, 2023
The starter in your Ford F150 is a small but powerful motor with a solenoid connected to both the battery and engine that turns the engine over. A bad starter won't allow the engine to turn over when you turn the key. If you hear no cranking sound when turning the key and know that the battery/electrical system is good, the starter probably needs replacing. You must disconnect the starter from the battery to remove it from the engine and replace it.
Things You'll Need:
- Jack stands
- Hex wrench
- Stud wrench
- Starter motor
- Voltmeter/test light
1. Disconnect the cable from the truck battery's negative terminal
Disconnect the cable from the truck battery's negative terminal. Raise and secure the F150 on jack stands.
2. Disconnect the wiring from the starter motor solenoid
Disconnect the wiring from the starter motor solenoid. Remove the hex nut holding the cable to the B+ terminal and remove the cable. Do the same with the cable connected to the S terminal.
3. Disconnect the starter's ground cable from its lower mounting stud
Disconnect the starter's ground cable from its lower mounting stud by removing its bolt, then remove the mounting fasteners attaching the starter motor to the engine. The starter has two or three bolts depending on the engine, with the lower bolt being a stud bolt. Remove the starter motor.
4. Install the new starter motor and torque the mounting fasteners
Install the new starter motor and torque the mounting fasteners to 18 foot-pounds each. Reconnect the ground cable to the lower mounting stud, then reconnect the wiring to the S and B+ terminals on the solenoid.
5. Lower the F150, reconnect the negative battery cable
Lower the F150, reconnect the negative battery cable and test the starter with the ignition key. Connect a voltmeter or test light to the solenoid's S terminal, and make sure the starter receives voltage at that terminal when the ignition switch is in the on position.

Comments from this video:
- Thank you for your video. It saved me and made the job so much easier. I appreciate how you let us know exactly what ratchet extensions are best and how to reach the bolts. I was able to replace the starter myself. I am a handy person, with home repair, but not a mechanic. I was able to replace the starter on why f-150 with not too much difficulty. Using the 3/8 inch to break the bolts loose and then using the 1/4 inch to finish the job was a great suggestion. Thank you or the simple and realistic video. I have not subscribed to your page for future repairs!!
- Been watching your videos a lot lately. I'm a diesel tech of 15 years and I just wanted to say I have a lot of respect for you and your videos. Always professional and always informative.
