🔧 Starter Motor - Replacement

The starter motor on your Equinox is mounted low on the engine/transmission side, so this job is usually done from underneath. You’ll disconnect the battery first, remove the electrical connections, then unbolt and swap the starter.

Difficulty Level: Intermediate | Estimated Time: 2-3 hours

⚠️ Safety & Precautions

• Disconnect the negative battery cable before touching the starter. The starter has constant battery power.
• Use jack stands under the vehicle. Never rely on the jack alone.
• Keep hands clear of the engine bay and underbody until the battery is disconnected.
• The exhaust and nearby parts may be hot. Let the vehicle cool fully.
• If equipped with start/stop or battery monitoring, expect battery-related faults after reconnecting; these usually clear after a normal start cycle.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Disconnect the battery

• Use a 10mm wrench to remove the negative battery cable from the battery.
• Move the cable aside so it cannot spring back and touch the terminal.

Step 2: Raise and secure the vehicle

• Use a floor jack (rated 3-ton minimum) to raise the front of the vehicle.
• Set the vehicle on jack stands and chock the rear wheels.
• Make sure the vehicle is stable before going underneath.

Step 3: Locate the starter motor

• From underneath, find the starter mounted at the engine/transmission bellhousing area.
• Identify the battery cable and control wire attached to the starter.

Step 4: Remove the starter wiring

• Use a 13mm socket to remove the battery cable nut from the starter main terminal.
• Remove the smaller control wire fastener with the appropriate 13mm socket or terminal tool if equipped.
• Set the wires aside carefully so they do not hang by the connectors.

Step 5: Remove the starter mounting bolts

• Use a 15mm socket, ratchet, and short extension to remove the starter mounting bolts.
• Support the starter with one hand as you remove the last bolt.
• Lower the starter out through the opening.

Step 6: Install the new starter

• Position the new starter in place by hand.
• Install the mounting bolts finger-tight first.
• Use a 15mm socket and torque wrench to tighten the starter bolts to 50 Nm (37 ft-lbs).

Step 7: Reconnect the starter wiring

• Reattach the battery cable and control wire to the starter.
• Use a 13mm socket to tighten the fasteners snugly.
• Tighten the main terminal nut to 13 Nm (115 in-lbs).

Step 8: Reassemble and lower the vehicle

• Inspect the area to make sure no tools are left behind.
• Lower the vehicle carefully off the jack stands.
• Reconnect the negative battery cable with the 10mm wrench and tighten it snugly.

Step 9: Test the repair

• Start the engine and listen for smooth cranking.
• Check for warning lights and make sure the starter wiring stays secure.
• If the engine does not crank, recheck battery connections and starter wiring.
