Difficulty Level: Intermediate | Estimated Time: 1.5-3.0 hours
⚠️ Safety & Precautions
- ⚠️ Disconnect the negative battery cable first to prevent an electrical short.
- ⚠️ Support the car on jack stands before working underneath; never rely on a jack.

- ⚠️ Keep the key/fob away from the vehicle while working.

📋 Before You Begin
- Park on a level surface, shift to Park, and set the parking brake.
- Place wheel chocks behind the rear tires.
- Open the hood and make sure all accessories are OFF.
- Disconnect the battery: use a 10mm socket to remove the negative terminal and tuck it aside so it can’t spring back.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Raise and support the front of the Soul
- Use a floor jack (rated 3-ton minimum) to lift the front at the center front jacking point.
- Set the car onto jack stands (rated 3-ton minimum) at the proper pinch-weld/support points.
- Give the car a gentle shake to confirm it’s stable. Stable first, tools second.
Step 2: Remove the lower engine cover (under-cover)
- Use a flat trim clip tool to pop out the plastic push-clips.
- Use a Phillips screwdriver #2 to remove any screws (some covers use a mix of clips/screws).
- Lower the cover and set it aside.
Step 3: Locate the starter and label the wires
- Use a flashlight and look up at the transmission/engine meeting point.
- You’ll see the starter body and two electrical connections: the large battery cable (B+) and the small control wire (signal).
- If helpful, take a quick photo before disconnecting anything. Photos prevent mix-ups later.
Step 4: Disconnect the starter electrical connections
- Remove the protective rubber boot from the large starter terminal by hand.
- Use a 12mm socket and 3/8" drive ratchet to remove the nut from the main battery cable (B+) terminal.
- Pull the cable off and move it aside so it can’t touch metal.
- For the small signal wire, use needle-nose pliers to release the connector tab (or pull straight off if it’s a push-on style).
Step 5: Remove the starter mounting bolts
- Use a 14mm socket, 3/8" drive ratchet, and a 6" extension.
- A “extension” is a straight bar that makes your ratchet reach farther into tight spaces.
- Remove the starter mounting bolts (typically 2 bolts). Support the starter with your free hand as the last bolt comes out.
Step 6: Remove the starter from the vehicle
- Wiggle the starter rearward to release it from the mounting surface.
- Angle it carefully and bring it down and out from underneath.
- Compare the old and new starters side-by-side (mounting ears, electrical studs, and nose length).
Step 7: Install the new starter
- Position the new starter into place by hand.
- Start the mounting bolts by hand first to avoid cross-threading.
- Tighten the starter mounting bolts using a 14mm socket and 3/8" drive torque wrench: Torque to 49 Nm (36 ft-lbs).
Step 8: Reconnect the starter wiring
- Install the main battery cable onto the B+ stud and thread the nut on by hand.
- Use a 12mm socket and 3/8" drive torque wrench: Torque to 12 Nm (9 ft-lbs).
- Reconnect the small signal wire until it clicks/fully seats (use needle-nose pliers only to guide it, not force it).
- Reinstall the rubber boot over the main terminal.
Step 9: Reinstall the under-cover and lower the vehicle
- Reinstall the under-cover using the Phillips screwdriver #2 and flat trim clip tool (replace broken clips as needed).
- Raise the car slightly with the floor jack (rated 3-ton minimum), remove the jack stands (rated 3-ton minimum), and lower the car.
Step 10: Reconnect the battery and verify operation
- Reconnect the negative battery terminal using a 10mm socket.
- Make sure tools are clear of the engine bay before starting.
✅ After Repair
- Start the engine and confirm it cranks strongly with no clicking or grinding noises.
- Check that no warning lights appear that weren’t there before.
- Do a quick recheck under the car for any dangling connectors or a loose under-cover.
- If you still have a no-crank, the next checks are battery condition and starter relay/fuse testing.
