🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the hood and locate the battery

• Check that the battery is secure and note how the hold-down is installed.

Step 2: Disconnect the negative cable

• Use a 10mm wrench to loosen the negative cable clamp.

• Negative first, always.

Step 3: Disconnect the positive cable

Step 4: Remove the battery hold-down

• Use a 13mm socket, ratchet, and extension to remove the battery hold-down clamp or bracket.
• Set the hardware aside in order so it goes back the same way.

Step 5: Remove the old battery

• Lift the battery straight up using both hands or a battery strap or lift handle.
• Place it on a level surface. Do not tip it.

Step 6: Clean the tray and terminals

• Inspect the battery tray for dirt, rust, or corrosion.
• If needed, clean the cable ends and tray area before installing the new battery.
• Install an anti-corrosion battery pad if you are using one.

Step 7: Install the new battery

• Set the new battery in the tray with the terminals in the same orientation as the old one.
• Make sure it sits flat and fully in the tray.

Step 8: Reinstall the hold-down

• Use a 13mm socket, ratchet, and extension to reinstall the battery hold-down.
• Torque to 8-10 Nm (71-89 in-lbs).
• The battery should not move when you push on it.

Step 9: Reconnect the positive cable

• Use a 10mm wrench to install the positive cable on the positive post.
• Tighten the clamp snugly. Do not overtighten.

Step 10: Reconnect the negative cable

• Use a 10mm wrench to install the negative cable on the negative post.
• Tighten the clamp snugly.
• Negative last prevents accidental shorting.

Step 11: Reset the battery monitor

• With the battery installed, start the engine and let it idle for a minute.
