🔧 Ignition Coils - Replacement

The ignition coils on your Equinox mount directly on top of the spark plugs and are straightforward to replace once the engine cover and intake plumbing are out of the way. Replacing a weak coil can fix misfires, rough idle, hesitation, and flashing check engine lights.

⚠️ Safety & Precautions

• Let the engine cool fully before starting. The turbo engine and nearby components can stay hot for a long time.
• Turn the ignition off and remove the key/fob from the vehicle.
• Disconnect the negative battery cable if you want the safest working condition. This helps prevent accidental shorts and false fault codes.
• Do not pull on the coil wire harness. Always release the connector lock first.
• Keep dirt out of the spark plug wells. Debris can damage the plugs and new coils.
