Follow these steps carefully
Let the engine cool completely before you touch anything. Pulling plugs out of a hot aluminum cylinder head risks stripping the threads, and the exhaust-side hardware stays hot enough to burn you for a long time after shutdown.
The 2.4L Ecotec wears a plastic sight shield over the top of the valve cover. Pull it straight up off its mounting studs and set it aside. You will see four ignition coils, one per cylinder.
Each ignition coil has its own electrical connector with a locking tab. Squeeze the release tab on all four connectors and pull them straight off the coils.
Each coil is held by a single small hold-down bolt. Remove all four bolts and keep them where they will not roll away.
Grip each ignition coil and pull it straight up out of its plug well. Twist gently if one resists; do not yank sideways. Lay them aside in order.
Use compressed air or a clean shop towel to clear dirt and debris out of each spark plug well BEFORE you loosen the plugs. Debris that drops into an open cylinder will damage the engine.
Using a 5/8-inch (16 mm) spark plug socket on a ratchet with an extension, loosen and remove the four old plugs. Note which cylinders show heavy black fouling; on the oil-burning 2.4L that points to oil consumption, not a bad plug design.
Confirm the new plugs are ACDelco 41-108 (GM 12620540) iridium, four of them. They ship pre-gapped at 0.035 in (0.9 mm) with a note not to change the gap. Verify with a gauge if you like, but do not adjust iridium plugs.
Thread each new plug in by hand several turns to make sure it is not cross-threading, then seat it with the ratchet. No factory torque figure for this engine could be verified, so no torque number is published here; seat each plug firmly without over-tightening in the aluminum head.
Smear a thin film of dielectric grease inside each coil boot, press the coils back down onto the plugs, reinstall the four hold-down bolts, reconnect each electrical connector until its tab clicks, and press the engine cover back onto its studs. Start the engine and confirm it idles smoothly.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
