⚠️ Safety & Precautions

• 🚨 Always support the truck with jack stands if you raise it; never rely only on a jack.
• 🔥 Engine oil and exhaust can get very hot; let the engine cool 15–30 minutes if recently driven.
• 🧯 Keep the area well-ventilated and away from open flames; used oil is flammable.
• 🧤 Wear gloves and safety glasses to protect your skin and eyes from hot oil.
• 🚗 Park on level ground and set the parking brake so the truck cannot roll.
• 🔌 Battery disconnection is not required for this job.
• 🌍 Dispose of used oil and the old filter at a recycling center or auto parts store; never dump it.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Safely raise and support the truck (if needed)

• If you want more room, use the floor jack (3-ton) to lift the front of the Sierra 1500 at the front crossmember.
• Place jack stands under the frame rails on both sides and gently lower the truck onto them with the floor jack.
• Make sure the truck is stable by gently pushing the body; it should not move.
• Truck is tall; some people skip jacking.

Step 2: Remove any skid plate or splash shield (if equipped)

• Slide under the front of the truck on a creeper or mat and locate the metal or plastic shield under the engine.
• Use a 13mm socket with the 3/8" ratchet to remove any bolts holding the skid plate.
• If there are plastic clips, gently pry them out with a plastic trim tool or flathead screwdriver.
• Lower the skid plate and set it aside so you can see the oil pan and filter.

Step 3: Position the drain pan

• Locate the oil pan at the bottom of the engine; the drain plug is a bolt at the lowest point, facing the rear or side.
• Place the drain pan under the drain plug, slightly toward the direction the oil will flow (usually rearward).
• Leave extra room; oil can shoot out.

Step 4: Remove the oil fill cap

• Open the hood and locate the oil fill cap on top of the engine cover.
• Twist the oil fill cap counterclockwise by hand and remove it; set it nearby.
• This helps the oil drain faster by letting air in.

Step 5: Drain the old engine oil

• Use a 13mm socket and 3/8" ratchet to loosen the oil drain plug.
• Finish removing the drain plug by hand while holding it firmly so it doesn’t fall into the pan.
• Let the oil drain completely into the drain pan; this can take 5–10 minutes.
• Inspect the drain plug and gasket; replace the drain plug gasket if it looks damaged or crushed.

Step 6: Reinstall and tighten the drain plug

• Once the oil is down to a slow drip, clean the area around the drain hole with a shop rag.
• Reinstall the drain plug by hand to avoid cross-threading.
• Use the 13mm socket and torque wrench to tighten the plug.
• Torque to 25 Nm (18 ft-lbs).
• Do not overtighten; oil pans crack easily.

Step 7: Remove the old oil filter

• Locate the oil filter (it’s a spin-on canister on the lower side of the engine block).
• Position the drain pan under the filter area; some oil will spill when you loosen it.
• Use the oil filter wrench to turn the filter counterclockwise until you can spin it off by hand.
• Carefully lower the filter into the drain pan and let it drain.
• Wipe the filter mounting surface on the engine with a shop rag and make sure the old rubber gasket is not stuck there.

Step 8: Prepare and install the new oil filter

• Take the new oil filter from its box.
• Dip a clean finger in fresh oil and lightly coat the rubber gasket on the new filter; this helps it seal and makes removal easier next time.
• Thread the new filter onto the engine by hand until the gasket first contacts the mounting surface.
• Once the gasket touches, tighten the filter an additional 3/4 turn by hand; use the oil filter wrench only if you cannot grip it well.
• Hand-tight is enough; don’t crush the gasket.

Step 9: Reinstall skid plate or splash shield (if removed)

• Lift the skid plate or shield back into position.
• Install the bolts by hand to avoid cross-threading, then tighten them with the 13mm socket and 3/8" ratchet.
• Reinstall any plastic clips using the plastic trim tool or flathead screwdriver.

Step 10: Lower the truck (if raised)

• Use the floor jack to lift the front of the Sierra 1500 slightly off the jack stands.
• Remove the jack stands from under the frame rails.
• Slowly lower the truck to the ground using the floor jack.

Step 11: Add new engine oil

• Place the funnel into the oil fill opening on top of the engine.
• Pour in about 7 quarts of 0W-20 full synthetic (dexos1 Gen 2) oil slowly.
• Wait a minute, then check the dipstick: pull it out, wipe it, reinsert fully, then pull it again to read the level.
• Add oil in small amounts until the oil level is at the “FULL” mark on the dipstick; total should be around 8 quarts with filter.
• Remove the funnel and reinstall the oil fill cap by hand.

Step 12: Start the engine and check for leaks

• Start the engine and let it idle for 1–2 minutes.
• Look underneath with a light at the drain plug and oil filter areas to make sure there are no leaks.
• Shut off the engine and wait 3–5 minutes for the oil to settle back into the pan.
• Recheck the oil level on the dipstick and top up if needed so it’s right at the “FULL” mark.

Step 13: Reset the oil life monitor

• Turn the ignition to ON (engine can be running or not).
• Use the steering wheel buttons to navigate the Driver Information Center.
• Follow this path: Home > Info > Oil Life.
• Press and hold the checkmark/OK button when “Oil Life” is displayed until it resets to 100%.
• Check your owner’s manual if menus look different.

Step 14: Clean up and dispose of used oil

• Pour the used oil from the drain pan into sealed containers using the funnel.
• Place the old oil filter in a plastic bag to prevent drips.
• Take the used oil and filter to a recycling center or auto parts store that accepts waste oil.
• Wipe any spilled oil from under the truck and the driveway with shop rags.

✅ After Repair

• 👂 Listen for any unusual noises from the engine; it should sound normal and smooth.
• 🧾 Check under the truck and around the oil filter and drain plug again after your first drive for any signs of leaks.
• 📅 Note your mileage and date so you know when the next oil change is due.
