🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the battery and identify the terminals

• The battery is in the engine bay. The negative (-) terminal usually has a black cable; the positive (+) usually has a red cover.
• Use safety glasses and nitrile gloves.

Step 2: Disconnect the negative (-) battery cable

• Use a 10mm socket with a 3/8" ratchet to loosen the negative terminal clamp nut.
• Wiggle the clamp straight up and off the terminal.
• Tuck the cable aside so it can’t spring back.

Step 3: Disconnect the positive (+) battery cable

• If equipped, open the positive terminal cover by hand.
• Use a 10mm socket with a 3/8" ratchet to loosen the positive terminal clamp nut.
• Remove the clamp from the terminal and position it safely aside.

Step 4: Remove the battery hold-down

• The hold-down is the bracket that keeps the battery from moving.
• Use a 10mm socket, 3/8" ratchet, and 3" extension to remove the hold-down fasteners.
• Lift off the hold-down pieces and set them aside in order.

Step 5: Remove the old battery

• Lift the battery straight up and out. Batteries are heavy—use good lifting form.
• Set it on the ground upright (not on its side).

Step 6: Clean the terminals and tray

• Use a battery terminal brush to clean corrosion from the inside of both cable clamps.
• Use shop rags to wipe the battery tray clean and dry.
• Install battery terminal anti-corrosion pads onto the new battery posts.

Step 7: Install the new battery

• Place the new battery into the tray in the same orientation as the old one (positive and negative on the same sides).
• Reinstall the hold-down hardware using a 10mm socket, 3/8" ratchet, and 3" extension.
• Finish with a torque wrench (5-30 Nm range): Torque the hold-down fasteners to 9 Nm (80 in-lbs).

Step 8: Reconnect the positive (+) cable first

• Push the positive clamp fully down onto the positive post.
• Use a 10mm socket and then a torque wrench (5-30 Nm range): Torque the terminal clamp nut to 5 Nm (44 in-lbs).
• Close the positive terminal cover (if equipped).

Step 9: Reconnect the negative (-) cable last

• Push the negative clamp fully down onto the negative post.
• Use a 10mm socket and then a torque wrench (5-30 Nm range): Torque the terminal clamp nut to 5 Nm (44 in-lbs).
• Apply battery terminal protectant spray to both terminals (light coat).

• Check that the headlights, horn, and power locks work.
• Reset the clock and radio presets if needed.
• Look at the battery: it should not move when you push it by hand (hold-down secure).
