- š§° Support the truck with jack stands on the frame; never rely on a floor jack alone.
- š Donāt let your wrench bridge the starterās main power stud to metal; it can arc hard.

šØ Step-by-Step Instructions
Follow these steps in order:
Step 1: Remove the lower splash shield
- Use a trim clip remover and flat-blade screwdriver to remove the push-clips/screws holding the lower splash shield.
- Set the shield and fasteners aside in a tray so nothing gets lost.
Step 2: Locate the starter motor
- From underneath, use a flashlight to find the starter where it bolts to the transmission bellhousing (itās a small motor with a thicker battery cable attached).
- If itās oily, wipe it clean first.
Step 3: Disconnect the starter wiring
- Remove the small solenoid connector: press the tab and pull it off by hand (donāt yank the wires).
- Remove the main battery cable nut using a 13mm socket and 3/8" ratchet.
- Move the cable aside so it canāt touch the starter stud.
- When reinstalling the main cable nut, Torque to 12 Nm (106 in-lbs).
- Apply a thin film of dielectric grease to the connector seal before reconnecting.
Step 4: Remove the starter mounting bolts
- Support the starter with one hand.
- Use a 15mm socket, 3/8" ratchet, and a 6" extension (and swivel joint if needed) to remove the starter mounting bolts.
- Slide the starter straight out of the bellhousing and lower it out.
Step 5: Compare the old and new starter
- Check the new starter matches the old one: same mounting ears, same electrical stud locations, same connector style.
- Clean the mounting surface on the bellhousing with a dry rag so the starter seats flat.
Step 6: Install the new starter
- Position the new starter into place by hand.
- Start the mounting bolts by hand first (this prevents cross-threading, which means damaging the threads by starting crooked).
- Tighten the mounting bolts using a 15mm socket and torque wrench: Torque to 48 Nm (35 ft-lbs).
Step 7: Reconnect the wiring
- Install the main battery cable onto the starter stud and tighten with a 13mm socket and torque wrench: Torque to 12 Nm (106 in-lbs).
- Reconnect the small solenoid connector until it clicks.
- Double-check the cable routing is not rubbing on sharp edges or touching the exhaust.
Step 8: Reinstall the splash shield and lower the truck
- Reinstall the lower splash shield using the trim clip remover and flat-blade screwdriver.
- Raise slightly with the floor jack, remove the jack stands, and lower the truck.
Step 9: Reconnect the battery
- Reconnect the negative battery terminal using a 10mm wrench.
- Torque to 7 Nm (62 in-lbs).
ā After Repair
- Start your Ranger and confirm it cranks strongly with no clicking or grinding.
- With the engine running, check that no warning lights appear and thereās no burning smell near the starter area.
- Recheck under the truck for any loose wiring near the starter after your first short drive.
