⚠️ Safety & Precautions

• ⚠️ Disconnect the battery negative cable before touching starter wiring (prevents short circuits).
• ⚠️ Support the car with jack stands on solid, level ground; never rely on a jack alone.
• ⚠️ Let the exhaust cool completely; the starter sits near hot exhaust components.
• ⚠️ Keep the battery cable away from metal while disconnected (it can arc).

📋 Before You Begin

• Park on level ground, shift to Park, and set the parking brake.
• Place wheel chocks behind the rear tires.
• Open the hood and disconnect the battery: use a 10mm socket to remove the negative (–) cable first, then position it so it can’t spring back.
• Raise the front of the car with a floor jack and set it securely on jack stands.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the lower splash shield (if equipped)

• Use a 7mm socket or 10mm socket (varies by fastener) with a 3/8" ratchet to remove the fasteners.
• Use a flat trim tool to pop any plastic clips loose without breaking them.

Step 2: Locate the starter and identify the wires

• The starter is mounted low on the engine/transmission area, accessed from underneath.
• You’ll typically see: the big battery cable on the large stud, and a smaller “signal” wire on a smaller terminal.
• Take a quick photo before removal.

Step 3: Disconnect the starter wiring

• Use a 13mm socket (or 13mm wrench) to remove the nut on the large battery cable stud, then pull the cable off.
• Use a 10mm socket to remove the nut on the small signal wire terminal (or carefully release the connector if it’s a push-on style).
• Move the wiring aside so it can’t get pinched during removal/installation.

Step 4: Remove the starter mounting bolts

• Support the starter with one hand.
• Use a 15mm socket with a 3/8" ratchet and a 6" extension (add a swivel/universal joint if needed) to remove the mounting bolts.
• Lower the starter out carefully once the bolts are out.

Step 5: Install the new starter

• Position the new starter into place by hand.
• Thread the mounting bolts in by hand first (prevents cross-threading).
• Tighten the mounting bolts with a 15mm socket, then Torque to 50 Nm (37 ft-lbs) using a torque wrench.

Step 6: Reconnect the starter wiring

• Apply a light smear of dielectric grease to the electrical connections (helps prevent corrosion).
• Install the large battery cable on the starter stud and tighten the nut using a 13mm socket to Torque to 15 Nm (11 ft-lbs).
• Reconnect the small signal wire and tighten using a 10mm socket to Torque to 12 Nm (106 in-lbs).
• Confirm the cables are routed away from exhaust/rotating parts.

Step 7: Reinstall the splash shield and lower the car

• Reinstall the lower splash shield using a 7mm socket or 10mm socket.
• Raise slightly with the floor jack, remove the jack stands, and lower the car.

Step 8: Reconnect the battery

• Reconnect the battery negative (–) cable using a 10mm socket.
• Tighten securely (snug plus a little); don’t over-tighten the battery post.

✅ After Repair

• Start the engine and confirm it cranks strongly with no clicking/grinding.
• With the engine running, listen underneath for any abnormal rubbing noises.
• Recheck that the starter wiring is not touching the exhaust and that all fasteners are tight.
