⚠️ Safety & Precautions

• ⚠️ Work on level ground and support the truck with jack stands—never rely on a jack alone.
• ⚠️ Hot oil can burn you; let the engine cool 10-20 minutes before draining.
• ⚠️ Keep oil off the exhaust and belts; wipe spills immediately.
• ⚠️ Wear gloves and safety glasses; used oil is a skin irritant.
• 🔋 Battery disconnect is not required for this service.

📋 Before You Begin

• Park your Sierra 1500 on level ground, set the parking brake, and place wheel chocks behind the rear tires.
• Warm the engine for 2-3 minutes, then shut it off and wait 10-20 minutes so the oil is warm (drains well) but not scalding.
• If you need more access, lift the front with a floor jack and support with jack stands under the frame.
• Have your drain pan (10-quart minimum) ready—your 5.3L holds a lot of oil.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the fill point (helps it drain)

• Open the hood and remove the oil fill cap by hand.
• Pull the dipstick out slightly by hand. This helps oil drain faster.

Step 2: Remove the lower splash shield (if equipped)

• If your Sierra 1500 has a lower shield under the front, use a 10mm socket with a ratchet to remove the bolts.
• Set the shield and hardware aside where you won’t lose them.

Step 3: Drain the old oil

• Slide the drain pan (10-quart minimum) under the oil pan drain plug.
• Use a 15mm socket with a ratchet to loosen the drain plug, then finish removing it by hand.
• Let the oil drain until it slows to an occasional drip (usually 5-10 minutes).

Step 4: Reinstall the drain plug

• Wipe the drain plug and the oil pan sealing surface with shop towels.
• Install a new drain plug gasket or replacement drain plug (if you’re replacing it).
• Thread the plug in by hand first (prevents cross-threading), then tighten with a 15mm socket.
• Torque to 25 Nm (18 ft-lbs) using a torque wrench (ft-lb).

Step 5: Remove the old oil filter

• Move the drain pan under the oil filter area—oil will spill when the filter comes off.
• Use an oil filter wrench to loosen the filter, then spin it off by hand.
• Check that the old rubber gasket came off with the filter (a stuck gasket can cause a leak).

Step 6: Install the new oil filter

• Put a light film of fresh oil on the new filter’s rubber gasket (use a gloved finger).
• Spin the new filter on by hand until the gasket touches, then tighten 3/4 turn by hand.
• If you are using a torque spec for your filter style: Torque to 25 Nm (18 ft-lbs) with an oil filter wrench and torque wrench (ft-lb) only if your wrench allows controlled torque.

Step 7: Reinstall the splash shield (if removed)

• Reposition the shield and start the bolts by hand.
• Tighten with a 10mm socket and ratchet until snug.

Step 8: Refill with new oil

• Place a funnel in the oil fill opening.
• Pour in 8 quarts of 5W-30 full synthetic, dexos1.
• Reinstall the oil fill cap by hand and fully seat the dipstick.

Step 9: Start, inspect, and set the level

• Start the engine and let it idle for 30-60 seconds.
• Shut it off and wait 3-5 minutes, then check the dipstick level and top off as needed using the funnel.
• Look underneath for leaks at the drain plug and oil filter using safety glasses.

Step 10: Reset the oil life monitor

• Key on (engine can be off).
• Use the steering wheel buttons to reach the Oil Life screen in the Driver Information Center.
• Press and hold SET/CLR until it resets to 100%.

✅ After Repair
