⚠️ Safety & Precautions

• ⚠️ Turn the truck OFF, remove the key, and keep it away from the vehicle.
• ⚠️ Do not let a tool touch both battery terminals (or terminal and metal) at the same time.
• ⚠️ Disconnect the negative (-) cable first and reconnect it last to reduce spark risk.
• ⚠️ Batteries are heavy and can leak acid—wear gloves and eye protection.
• ⚠️ No battery “registration” is required on your Silverado after replacement.

📋 Before You Begin

• Park on level ground, shift to Park, and set the parking brake.
• Pop the hood and let the engine bay cool if it’s hot.
• If you want to keep radio presets, you can use a “memory saver” (a small device that powers the truck through the OBD port while the battery is out). Optional for this job.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the battery

• Open the hood and locate the battery on the passenger side of the engine bay.
• If any plastic cover or air duct is in the way, remove it using the appropriate fasteners with a 10mm socket and 3/8" ratchet.

Step 2: Disconnect the negative (-) cable first

• Find the negative (-) battery terminal (usually marked “-” and/or has a black cable).
• Use a 10mm socket with a 3/8" ratchet to loosen the terminal clamp nut.
• Twist and lift the clamp straight up off the battery post.
• Tuck the cable end aside so it can’t spring back and touch the terminal.

Step 3: Disconnect the positive (+) cable

• Find the positive (+) terminal (usually marked “+” and/or has a red cover).
• Flip open/remove the red protective cover if equipped.
• Use a 10mm socket with a 3/8" ratchet to loosen the terminal clamp nut.
• Lift the clamp straight up off the post and move it aside so it can’t touch metal.

Step 4: Remove the battery hold-down

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

Step 5: Remove the old battery

• Lift the battery straight up and out. Batteries are heavy—use safe lifting posture.
• Set the old battery upright on the ground.

Step 6: Clean the terminals and battery tray

• If you see white/blue buildup, that’s corrosion.
• Use a battery terminal brush (specialty) to clean the inside of the cable clamps and the battery posts.
• Wipe the tray area clean (keep debris out of the engine bay).
• Install battery terminal anti-corrosion washers onto the new battery posts.
• Clean metal = better starting.

Step 7: Install the new battery and secure it

• Place the new battery into the tray in the same orientation as the old one.
• Reinstall the hold-down bracket and start the bolt by hand to avoid cross-threading.
• Tighten using a 13mm socket and 3/8" ratchet.
• Torque to 15 Nm (11 ft-lbs) using a torque wrench (foot-pound).

Step 8: Reconnect the positive (+) cable first

• Push the positive clamp fully down onto the positive post.
• Tighten the clamp using a 10mm socket and 3/8" ratchet.
• Torque to 10 Nm (89 in-lbs) using a torque wrench (inch-pound).
• Reinstall/close the red protective cover if equipped.

Step 9: Reconnect the negative (-) cable last

• Push the negative clamp fully down onto the negative post.
• Tighten the clamp using a 10mm socket and 3/8" ratchet.
• Torque to 10 Nm (89 in-lbs) using a torque wrench (inch-pound).

Step 10: Protect and recheck

• Lightly spray the terminals with battery terminal protectant spray.
• Grab each cable end and confirm it’s tight (it should not rotate by hand).
• Reinstall any covers/ducts removed earlier using a 10mm socket.

✅ After Repair

• Start the engine and confirm normal cranking speed.
• Check for warning lights; if any appear, shut off and recheck terminal tightness.
• Reset the clock and radio presets if they were lost.
• Dispose of the old battery properly—most parts stores give a core credit.
