🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the battery

• Open the hood and find the battery in the engine bay.
• Remove any plastic cover if equipped. Use your hands first; if needed, use a trim tool carefully.

Step 2: Disconnect the negative terminal

• Use the 10mm wrench to loosen the negative cable clamp.
• Lift the negative cable off the battery post and move it aside so it cannot touch the battery.
• Remove the negative side first.

Step 3: Disconnect the positive terminal

• Use the 10mm wrench to loosen the positive cable clamp or terminal fastener.
• Remove the positive cable and keep it from touching metal.

Step 4: Remove the battery hold-down

• Take out the hold-down bracket and set the hardware aside.
• Torque for installation: tighten the hold-down to 15 Nm (11 ft-lbs).

Step 5: Lift out the old battery

Step 7: Install the new battery

• Set the new battery in the tray in the same orientation as the old one.
• Reinstall the hold-down bracket using the 13mm socket and ratchet.
• Torque the hold-down to 15 Nm (11 ft-lbs).

Step 8: Reconnect the positive terminal

• Use the 10mm wrench to tighten the clamp snugly.
• Torque to 6 Nm (53 in-lbs) if a torque spec is practical on your clamp style.

Step 9: Reconnect the negative terminal

• Install the negative cable last.
• Use the 10mm wrench to tighten the clamp snugly.
• Torque to 6 Nm (53 in-lbs) if applicable.
• Apply a light coat of battery terminal protector spray to help slow corrosion.
