⚠️ Safety & Precautions

• ⚠️ Always disconnect the negative (-) cable first and reconnect it last.
• ⚠️ Keep metal tools away from the positive (+) terminal and body metal at the same time (that can short and spark).
• ⚠️ Wear eye protection—battery corrosion is acidic.
• ⚠️ If the battery is leaking, do not touch the liquid; neutralize with baking soda and water.
• 🔋 Battery disconnect is required for this repair.

📋 Before You Begin

• Park on level ground, shift to P, and turn the ignition fully OFF.
• Open the hood and let the engine bay cool if it’s hot.
• If you want to keep radio presets/settings, use a memory saver (a small device that keeps power while the battery is out). If you don’t have one, it’s okay—your truck will relearn.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the battery

• Locate the battery in the engine bay.
• If there’s a battery cover or intake snorkel in the way, remove the fasteners using a 8mm socket or 10mm socket as needed, then set the pieces aside.

Step 2: Disconnect the negative (-) cable

• Use a 10mm socket and 1/4" drive ratchet to loosen the negative terminal clamp nut.
• Twist and lift the clamp off the battery post, then tuck the cable to the side so it can’t spring back.
• Negative first prevents accidental shorting.

Step 3: Disconnect the positive (+) cable

• Use a 10mm socket to loosen the positive terminal clamp nut.
• Lift the clamp off and position it so it cannot touch metal.

Step 4: Remove the battery hold-down

• At the base of the battery, remove the hold-down bolt using a 10mm socket with a 6" extension and 1/4" drive ratchet.
• Lift the hold-down bracket out and set it aside.

Step 5: Remove the old battery

• Wearing nitrile gloves and safety glasses, lift the battery straight up and out.
• Set it on the ground upright (batteries are heavy—lift with your legs).

Step 6: Clean and prep the terminals

• Use a battery terminal brush to clean the inside of both cable clamps until the metal looks bright.
• Install battery terminal anti-corrosion pads on the new battery posts (one per post).

Step 7: Install the new battery

• Place the new battery into the tray in the same orientation as the old one.
• Reinstall the hold-down bracket and bolt using a 10mm socket, then Torque to 9 Nm (80 in-lb) with a torque wrench.

Step 8: Reconnect the positive (+) cable first

• Install the positive clamp onto the positive battery post.
• Tighten using a 10mm socket, then Torque to 5 Nm (44 in-lb) with a torque wrench.

Step 9: Reconnect the negative (-) cable last

• Install the negative clamp onto the negative battery post.
• Tighten using a 10mm socket, then Torque to 5 Nm (44 in-lb) with a torque wrench.

Step 10: Protect and reassemble

• Spray the terminals with battery terminal protectant spray.
• Reinstall any covers/snorkels you removed using the same 8mm socket or 10mm socket.

✅ After Repair

• Start the engine and confirm it cranks strongly.
• Check that the battery warning light is off.
• With the engine running, verify lights, wipers, and HVAC work normally.
• Expect a brief relearn: idle may be slightly high/low for a few minutes after reconnecting the battery.
