⚠️ Safety & Precautions

• ⚠️ Let the engine cool 15–30 minutes to avoid burns from hot oil and exhaust.
• ⚠️ If you lift the truck, support it with jack stands on the frame—never rely on a floor jack alone.
• ⚠️ Keep oil off belts and exhaust parts to reduce smoke/odor after startup.
• ⚠️ No battery disconnect is required for this job.

📋 Before You Begin

• Park your Sierra 1500 on level ground and set the parking brake.
• Place wheel chocks behind the rear tires.
• Warm the engine for 2–3 minutes, then shut it off. Warm oil drains faster.
• If equipped with an underbody panel/air deflector that blocks access, plan to remove it with a 10mm socket.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and secure the front (if needed)

• If you have enough room to reach the drain plug and filter safely, you can skip lifting.
• If you need clearance, use a floor jack (rated 3-ton minimum) to lift the front at a safe jacking point, then support with jack stands (rated 3-ton minimum).
• Keep wheel chocks in place.

Step 2: Remove any splash shield/air deflector (if equipped)

• Use a 10mm socket and 3/8" drive ratchet to remove the bolts holding the panel.
• Set the bolts aside so they don’t get lost.

Step 3: Drain the engine oil

• Place the oil drain pan (10-quart minimum) under the oil pan drain plug.
• Use a 15mm socket and 3/8" drive ratchet to loosen and remove the drain plug.
• Let the oil drain until it slows to an occasional drip.
• Wipe the drain plug and sealing area with shop rags.

Step 4: Reinstall the drain plug

• Replace the oil drain plug gasket if your Sierra 1500 uses a separate seal.
• Thread the drain plug in by hand first (to avoid cross-threading).
• Use a torque wrench (10–50 ft-lbs range) and 15mm socket to tighten: Torque to 25 Nm (18 ft-lbs).

Step 5: Remove the oil filter

• Move the oil drain pan (10-quart minimum) under the oil filter area (some oil will spill).
• Use an oil filter wrench to loosen the oil filter, then spin it off by hand.
• Make sure the old rubber gasket came off with the filter (it can stick to the engine). Double-gasket causes major leaks.

Step 6: Install the new oil filter

• Put a light film of new oil on the new filter’s rubber gasket using a gloved finger.
• Spin the filter on by hand until the gasket touches, then tighten an additional 3/4 turn by hand.
• If you must use the oil filter wrench to snug it, use only gentle pressure—don’t crush the filter.

Step 7: Refill with new engine oil

• Open the hood and remove the oil fill cap.
• Insert a funnel and add Engine oil (0W-20 full synthetic, dexos1-approved)—start with about 7.5 quarts.
• Reinstall the oil fill cap.

Step 8: Start, check for leaks, and set the oil level

• Start the engine and let it idle 30–60 seconds.
• Shut the engine off and inspect the drain plug and oil filter area with safety glasses on for leaks.
• Wait 5 minutes, then check the dipstick, wipe with shop rags, reinsert, and re-check.
• Add oil as needed to reach the proper level (usually close to the full 8 quarts total with filter).

Step 9: Reinstall the splash shield (if removed) and lower the truck

• Reinstall the panel using the 10mm socket and 3/8" drive ratchet.
• Remove jack stands (rated 3-ton minimum) and lower with the floor jack (rated 3-ton minimum).

Step 10: Reset the Oil Life monitor

• Turn the key to ON (engine off) or put the truck in accessory mode.
• Use the steering wheel buttons to open the Driver Information Center oil screen, then reset.
• Menu path (common): Oil Life > Press and hold SET/CLR to reset

✅ After Repair

• Recheck for leaks after your first short drive and again the next morning.
• Verify the dipstick level is still correct on level ground.
• Dispose of used oil and the old filter at an oil recycling center or parts store—don’t dump it.
