🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Disconnect the negative cable

• Use a 10mm wrench to loosen the negative terminal clamp.
• Remove the negative cable from the battery and tuck it aside so it cannot spring back.
• Always disconnect negative first.

Step 2: Disconnect the positive cable

• Use a 10mm wrench to loosen the positive terminal clamp.
• Remove the positive cable and keep it away from metal surfaces.

Step 3: Remove the battery hold-down

• Use an 8mm socket and ratchet to remove the battery hold-down fastener.
• Lift off the hold-down bracket and set it aside.

Step 4: Remove the old battery

• Lift the battery straight up and out of the tray. Batteries are heavy, so use both hands.
• If the battery tray is dirty or corroded, clean it before installing the new battery.

Step 5: Clean the terminals and tray

• Use a battery terminal brush to clean corrosion from the cable ends.
• Wipe the tray clean and make sure the hold-down area is free of debris.
• A clean connection helps starting.

Step 6: Install the new battery

• Place the new battery in the tray with the terminals in the same orientation as the original.
• Reinstall the hold-down bracket and tighten the fastener with the 8mm socket.
• Torque to snug fit only; do not overtighten the battery hold-down.

Step 7: Reconnect the cables

• Install the positive cable first and tighten it with the 10mm wrench.
• Install the negative cable last and tighten it with the 10mm wrench.
• Make sure both clamps are fully seated and do not twist by hand.

Step 8: Protect the terminals

• Spray a light coat of battery terminal protector spray on both terminals if available.
• Close the hood and start the truck to verify normal cranking and operation.
