🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open hood and locate the battery

• Open the hood and find the battery in the engine bay.
• Identify the negative (-) terminal (usually black cable) and positive (+) terminal (usually under a red cover).

Step 2: Disconnect the negative (-) cable

• Use a 10mm socket with a 3/8" ratchet to loosen the negative terminal clamp nut.
• Twist and lift the clamp straight up off the post.
• Move the cable end aside so it cannot spring back onto the battery.
• Negative off first prevents accidental shorting.

Step 3: Disconnect the positive (+) cable

• If equipped, flip open the positive terminal cover.
• Use a 10mm socket to loosen the positive terminal clamp nut.
• Lift the clamp off the post and position it safely aside.

Step 4: Remove the battery hold-down

• Locate the hold-down at the base of the battery (it keeps the battery from moving).
• Use a 13mm socket, 6" extension, and 3/8" ratchet to remove the hold-down bolt.
• Remove the hold-down bracket/wedge and set it aside.

Step 5: Remove the old battery

• Lift the battery straight up and out. Use proper lifting form; it’s heavy.
• Place it on the ground upright.

Step 6: Clean the cable clamps and tray

• Use a battery terminal brush (specialty) to clean the inside of both cable clamps until the metal is bright.
• Wipe out any debris in the battery tray.
• A clean connection prevents no-start issues.

Step 7: Install the new battery and secure it

• Set the new battery into the tray in the same orientation as the old one (posts in the same positions).
• Reinstall the hold-down bracket/wedge.
• Use a 13mm socket and torque wrench to tighten the hold-down bolt: Torque to 25 Nm (18 ft-lbs).

Step 8: Reconnect the positive (+) cable first

• Install a battery terminal anti-corrosion pad on the positive post (felt ring).
• Push the positive clamp fully down onto the post.
• Use a 10mm socket and torque wrench to tighten: Torque to 5 Nm (44 in-lbs).
• Close the positive terminal cover (if equipped).

Step 9: Reconnect the negative (-) cable last

• Install a battery terminal anti-corrosion pad on the negative post.
• Push the negative clamp fully down onto the post.
• Use a 10mm socket and torque wrench to tighten: Torque to 5 Nm (44 in-lbs).

Step 10: Protect the terminals

• Lightly spray both terminals with battery terminal protectant spray.
• Do not soak the area; a light coat is enough.
