🔧 Sierra 1500 - Engine Oil & Oil Filter Replacement

This service drains the old engine oil, replaces the oil filter, and refills the engine with the correct spec oil. Fresh oil protects the 5.3L V8 from wear, helps it run cooler, and keeps the oil life monitor accurate.

Difficulty Level: Beginner | Estimated Time: 1-1.5 hours


⚠️ Safety & Precautions

  • Let the engine cool before starting so you do not burn yourself on hot oil or exhaust parts.
  • Use jack stands if you raise the truck. Never rely on a jack alone.
  • Work on level ground and keep the parking brake set.
  • Used oil is hazardous. Keep it off the ground and out of drains.
  • No battery disconnect is required for this job.

🔧 Required Tools

You'll need the following tools for this repair:

  • 15mm socket
  • 3/8-inch ratchet
  • Oil filter wrench or cap wrench
  • Drain pan
  • Funnel
  • Floor jack (rated 3-ton minimum)
  • Jack stands (rated for truck weight)
  • Wheel chocks
  • Shop towels
  • Safety glasses
  • Nitrile gloves
  • Torque wrench

🔩 Required Parts

HowToo sells all the parts you need for this repair:

  • Engine oil (0W-20 full synthetic dexos1) - Qty: 8 quarts
  • Oil filter - Qty: 1
  • Oil drain plug gasket - Qty: 1

📋 Before You Begin

  • Park on level ground and set the parking brake.
  • Chock the rear wheels if you raise the front of the truck.
  • Warm the engine for 2-3 minutes only if the oil is very cold. Do not make it hot.
  • Turn the ignition off and remove the key or fob from the vehicle.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise and secure the truck

  • Use a floor jack to lift the front of the truck at the approved lift points.
  • Place jack stands under the frame and lower the truck onto them.
  • Shake the truck gently before crawling under it.

Step 2: Remove the oil fill cap and dipstick

  • Open the hood.
  • Remove the oil fill cap by hand and pull the dipstick up a few inches.
  • This helps the oil drain faster.

Step 3: Drain the engine oil

  • Position the drain pan under the oil pan drain plug.
  • Use a 15mm socket and 3/8-inch ratchet to remove the drain plug.
  • Let the oil drain fully.
  • Install the drain plug with a new gasket and tighten it to 25 Nm (18 ft-lbs).

Step 4: Remove the oil filter

  • Move the drain pan under the oil filter area.
  • Use an oil filter wrench or cap wrench to loosen the filter.
  • Spin the filter off by hand once it is loose.
  • Check that the old filter gasket came off with the filter.
  • Double-check for a stuck old gasket.

Step 5: Install the new oil filter

  • Wipe the filter mounting surface clean with a shop towel.
  • Lightly coat the new filter gasket with fresh oil.
  • Install the new filter by hand until the gasket touches, then tighten it an additional 3/4 turn by hand.
  • Do not overtighten.

Step 6: Refill with fresh oil

  • Lower the truck to level ground.
  • Use a funnel to add 7.5 to 8 quarts of 0W-20 full synthetic dexos1.
  • Install the oil cap.
  • Start the engine and let it run for 30-60 seconds.
  • Shut the engine off and wait 5 minutes.
  • Check the dipstick and top off as needed to reach the full mark.

Step 7: Check for leaks and reset oil life

  • Look under the truck for leaks at the drain plug and oil filter.
  • On the dash, use the driver information controls to reset the oil life monitor.
  • If equipped, follow the menu path shown in the cluster for oil life reset.

✅ After Repair

  • Recheck the oil level after a short drive and another 5-minute wait.
  • Inspect the drain plug and filter again for seepage.
  • Dispose of used oil and the old filter at a recycling center or parts store.
