📋 Before You Begin

• Park on level ground, turn the ignition off, and remove the key from the vehicle.
• Open the trunk and keep it open while you work.
• If you have a radio preset/clock you care about, write them down now (they may reset).
• Let the car sit 3–5 minutes after key-off so modules go to sleep.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the battery

• Open the trunk and locate the battery cover panel on the trunk side area.
• Use a trim clip tool to carefully pop any retainers/clips and remove the cover.
• Use a flashlight to identify the negative (-) and positive (+) terminals before touching anything.

Step 2: Disconnect the negative cable (first)

• Use a 10mm socket with a 3/8" ratchet to loosen the negative terminal clamp nut.
• Lift the negative cable off the battery post and push it aside so it cannot spring back.
• Tip: Tuck it behind the cover edge.

Step 3: Disconnect the positive cable (second)

• Use a 10mm socket with a 3/8" ratchet to loosen the positive terminal clamp nut.
• Lift the positive cable off and position it so it cannot touch metal.

Step 4: Disconnect the battery vent tube (if equipped)

• Look for a small plastic/rubber tube attached to the side of the battery.
• Pull it straight out by hand; if tight, gently work it loose without tearing it.
• Tip: This tube vents battery gases outside.

Step 5: Remove the battery hold-down

• Locate the hold-down bracket/clamp at the base of the battery.
• Use a 13mm socket, 6" extension, and 3/8" ratchet to remove the hold-down bolt(s).
• Set the bracket and bolt(s) aside where they won’t get lost.

Step 6: Remove the old battery

• With nitrile gloves on, lift the battery straight up and out (keep it upright).
• Place it on the ground in a stable spot.
• Tip: Batteries are heavy—lift with legs.

Step 7: Install the new battery

• Lower the new battery into the tray in the same orientation as the old one.
• Reinstall the hold-down bracket using a 13mm socket and 3/8" ratchet.
• Tighten with a torque wrench: Torque to 15 Nm (11 ft-lbs).

Step 8: Reconnect the vent tube (if equipped)

• Push the vent tube back into the battery vent port until fully seated.

Step 9: Reconnect the positive cable (first)

• Install the positive terminal clamp onto the battery post.
• Use a 10mm socket and 3/8" ratchet to tighten the clamp.
• Tighten with a torque wrench: Torque to 10 Nm (89 in-lbs).
• Install battery terminal anti-corrosion pads if you’re using them.

Step 10: Reconnect the negative cable (last)

• Install the negative terminal clamp onto the battery post.
• Use a 10mm socket and 3/8" ratchet to tighten the clamp.
• Tighten with a torque wrench: Torque to 10 Nm (89 in-lbs).
• Lightly apply battery terminal protectant spray after connections are tight.

Step 11: Reinstall the battery cover

• Reinstall the trunk-side cover panel.
• Press clips back in place by hand (or guide them in with the trim clip tool).

✅ After Repair

• Start your Camaro and confirm it cranks strongly and idles normally.
• Check that no battery cables can move by hand (they should be snug).
• Reset the clock and radio presets if needed.
• If the auto-up/down windows don’t work right, cycle each window fully down, then fully up, and hold the switch up for 2 seconds to relearn.
• Recycle the old battery—most parts stores will take it and may refund a core charge.
