About This Video

Well, guys, we here. In this DIY video, I’m changing the engine oil of the 2nd gen Chevrolet Trailblazer (2011–2020/2021 models) with the 2.8L Duramax diesel. I walk you through the exact tools I use—ratchet with 15mm for the drain plug, 27mm for the oil filter cap, flathead screwdriver for the intake clamps, torque wrench (up to 25 Nm), drain pan, funnel, gloves, and shop towels—plus the correct oil and filter setup (cartridge type with O-rings). I start by removing the oil filler cap, then I pull the intake hose so I can access the oil filter housing. I show how the cartridge filter clips in, how many O-rings you need to replace (yes, there are multiple), and why I always coat the new O-ring with oil so it seals properly and is easier to remove next time. After hand-tightening the filter cap, I torque it to 25 Nm. Underneath, I locate the oil pan past the stock skid plate, remove the drain plug, let it drain smoothly, then reinstall with a new drain plug seal. The Trailblazer takes around 6 liters of 5W-30, but I fill while checking the dipstick so I don’t overfill. After running the engine, I recheck for leaks and recheck the dipstick again since the filter fills up—then I top up and you’re good to go.
