🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the battery and remove any covers

• Open the hood and locate the battery in the engine bay.
• If your Equinox has a battery cover, remove it by hand (no tools) or use a 10mm socket if it’s bolted.

Step 2: Disconnect the negative (-) cable first

• Use a 10mm socket to loosen the negative terminal clamp nut.
• Twist and lift the clamp off the negative post, then tuck the cable aside so it cannot spring back.
• If the clamp is stuck, use a battery terminal puller (specialty) (a small puller that separates a stuck terminal safely).
• Torque to 17 Nm (13 ft-lbs) when reinstalling this clamp.

Step 3: Disconnect the positive (+) cable

• Use a 10mm socket to loosen the positive terminal clamp nut.
• Lift the clamp off the positive post and move it aside.
• Torque to 17 Nm (13 ft-lbs) when reinstalling this clamp.

Step 4: Remove the battery hold-down

• At the base of the battery, remove the hold-down bolt using a 13mm socket with a 6" extension and 3/8" ratchet.
• Remove the hold-down bracket and set it aside.
• Torque to 20 Nm (15 ft-lbs) when reinstalling the hold-down bolt.

Step 5: Lift out the old battery

• Wear protective gloves and safety glasses.
• Lift the battery straight up and out. Batteries are heavy—use good posture.
• Keep it level to prevent leaks.

Step 6: Clean the tray and terminals

• Inspect the battery tray for corrosion and debris; wipe it clean.
• Use a battery terminal brush to clean the inside of both cable clamps if there is white/green buildup.

Step 7: Install the new battery

• Place the new battery into the tray in the same orientation as the old one.
• Reinstall the hold-down bracket and tighten with a 13mm socket.
• Torque to 20 Nm (15 ft-lbs).

Step 8: Reconnect cables (positive first, negative last)

• Install anti-corrosion pads on the posts (if using).
• Reconnect the positive (+) clamp first and tighten using a 10mm socket.
• Torque to 17 Nm (13 ft-lbs).
• Reconnect the negative (-) clamp last and tighten using a 10mm socket.
• Torque to 17 Nm (13 ft-lbs).
• Apply battery terminal protectant spray after everything is tight.
