🔧 Regal - Starter Motor Replacement
The starter motor spins the engine so it can start. If it’s failing, you may hear a single click, slow cranking, or no crank at all. On your Regal, the starter is bolted to the transmission bellhousing and is typically accessed from underneath.
Difficulty Level: Intermediate | Estimated Time: 1.5-3.0 hours
Assumption: Stock intake/undertray; access is from below.
⚠️ Safety & Precautions
- ⚠️ Disconnect the battery negative cable before touching the starter wiring (prevents shorts and burns).
- ⚠️ Support the car with jack stands on solid, level ground; never rely on a floor jack alone.
- ⚠️ Let the exhaust cool completely; the starter sits near hot exhaust parts.
- ⚠️ Keep the key fob away from the car while working so it can’t accidentally crank.

📋 Before You Begin
- 🅿️ Park on level ground, shift to Park, and set the parking brake.
- 🧱 Chock the rear wheels with wheel chocks.
- 🔋 Open the hood and disconnect the battery negative cable using a 10mm socket; move it aside so it can’t spring back.
- 💡 Set up a work light under the front of the car so you can clearly see the starter.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Raise and support the front of the car
- Use a floor jack to lift the front at the proper front jacking point.
- Place jack stands under the front support points and lower the car onto them.
- Give the car a gentle shake to confirm it’s stable before you get underneath.
Step 2: Remove the lower splash shield (undertray)
- Use a 10mm socket to remove the bolts.
- Use a flat trim tool to pop any plastic clips (a trim tool is a flat pry tool that helps remove clips without breaking them).
- Set all hardware aside in a tray so nothing gets lost.
Step 3: Locate the starter motor
- From underneath, look where the engine meets the transmission (the “bellhousing,” which is the housing where the transmission bolts to the engine).
- The starter is a small motor with a thicker battery cable going to it.
Step 4: Disconnect the starter wiring
- Remove the small connector (starter solenoid trigger wire) by releasing the lock tab using needle-nose pliers as needed, then pull straight off.
- Remove the nut holding the main battery cable to the starter using a 13mm socket.
- Pull the cable off and tuck it safely aside.
- Apply a tiny amount of dielectric grease to the small connector seal during reassembly. Helps prevent moisture problems.
Step 5: Remove the starter mounting bolts
- Support the starter with one hand while removing bolts with the other.
- Use a 15mm socket with a 6" extension and swivel socket adapter if access is tight.
- Remove the starter mounting bolts and keep them for reuse unless your new starter includes replacements.
Step 6: Remove the starter
- Carefully lower the starter out of the bellhousing area.
- If it hangs up, rotate it slowly to clear nearby brackets/lines—don’t force it.
Step 7: Prep the mounting surface
- Use a small wire brush to clean the starter mounting area on the transmission/engine.
- This helps the starter sit flat and helps grounding (the starter grounds through its mounting).
Step 8: Install the new starter
- Position the new starter in place by hand.
- Start the mounting bolts by hand first (prevents cross-threading).
- Tighten with a 15mm socket, then final-tighten with a torque wrench: Torque to 50 Nm (37 ft-lbs).
Step 9: Reconnect the starter wiring
- Install the main battery cable onto the starter terminal using a 13mm socket: Torque to 13 Nm (115 in-lbs).
- Reconnect the small solenoid connector until it clicks into place.
- Double-check both connections are fully seated and routed away from exhaust/rotating parts.
Step 10: Reinstall the undertray and lower the car
- Reinstall the splash shield using the 10mm socket and flat trim tool for clips.
- Lift slightly with the floor jack, remove jack stands, and lower the car.
Step 11: Reconnect the battery
- Reconnect the battery negative cable using a 10mm socket.
- Apply a light coat of battery terminal grease to reduce corrosion.
✅ After Repair
- 🔑 Start the engine and listen: cranking should be strong and smooth.
- 🔍 Check under the hood and underneath for any loose tools, dangling wires, or rubbing cables.
- 🛑 If you hear grinding or the starter stays engaged after starting, shut the engine off immediately and recheck mounting and wiring.
