🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the negative cable

• Use the 8mm socket and ratchet to loosen the negative battery terminal clamp.
• Lift the negative cable off the battery post and move it aside so it cannot spring back.
• Negative first, always.

Step 2: Loosen the positive cable

• Use the 8mm socket to loosen the positive terminal clamp.
• Remove the positive cable and keep it away from the battery.

Step 3: Remove the battery hold-down

• Use the 10mm socket, ratchet, and short extension to remove the battery hold-down clamp or bracket.
• Set the hardware aside in case you reuse it.
• Torque on reassembly: 9 Nm (80 in-lbs)

Step 4: Lift out the old battery

• Carefully lift the battery straight up and out of the tray. Batteries are heavy, so use both hands.
• If corrosion is present, neutralize it with the baking soda and water solution before cleaning.
• Keep the battery upright.

Step 5: Clean the tray and terminals

• Use the wire brush to clean corrosion from the terminals and cable ends.
• Wipe the battery tray clean and dry.
• Inspect the cables for cracks or swelling.

Step 6: Install the new battery

• Place the new battery in the tray with the terminals in the same orientation as the old one.
• Reinstall the hold-down bracket using the 10mm socket.
• Torque the hold-down to 9 Nm (80 in-lbs)

Step 7: Connect the positive cable

• Install the positive cable first and tighten the clamp with the 8mm socket.
• Torque the terminal clamp snugly to 5-6 Nm (44-53 in-lbs)

Step 8: Connect the negative cable

• Install the negative cable last and tighten it with the 8mm socket.
• Torque the terminal clamp snugly to 5-6 Nm (44-53 in-lbs)
• Spray a light coat of battery terminal protectant spray on both terminals if desired.
