ā ļø Safety & Precautions
- ā ļø Hot oil can burnālet the engine cool 20-30 minutes before draining.
- ā ļø If you lift your Sierra 1500, support it with jack stands on the frameānever rely on a floor jack alone.
- ā ļø Keep oil off the exhaust and belts; wipe spills immediately.
- ā ļø No battery disconnect is required for this job.

š© Required Parts
HowToo sells all the parts you need for this repair:
- Engine oil (SAE 5W-30, dexos1-approved) - Qty: 6 quarts
- Engine oil filter - Qty: 1
- Oil drain plug gasket/washer (if equipped) - Qty: 1
š Before You Begin
- Park your Sierra 1500 on level ground and set the parking brake.
- Chock the rear wheels with wheel chocks.
- Gather your oil drain pan, funnel, and rags so youāre not scrambling mid-drain.
- Warm oil drains faster than cold oil.
šØ Step-by-Step Instructions
Follow these steps in order:
Step 1: Safely access the underside
- If you need extra room, lift the front with a floor jack (rated 3-ton minimum) and support with jack stands (rated 3-ton minimum).
- Give the truck a firm shake test to confirm itās stable before you go underneath.
Step 2: Remove the oil fill cap and set up the drain pan
- Open the hood and remove the oil fill cap by hand. This helps the oil drain smoothly.
- Place the oil drain pan (at least 10-quart capacity) under the oil pan drain plug.
Step 3: Drain the engine oil
- Use a 15mm socket with a 3/8" drive ratchet to loosen the drain plug.
- Finish removing the plug by hand, then let the oil fully drain into the pan.
- Inspect the drain plug and the sealing surface. Replace the oil drain plug gasket/washer (if equipped) if it looks crushed, torn, or hardened.
Step 4: Reinstall and torque the drain plug
- Thread the drain plug in by hand first (this helps prevent cross-threading).
- Use a torque wrench (10-50 ft-lbs range) with a 15mm socket to tighten the drain plug: Torque to 25 Nm (18 ft-lbs).
Step 5: Remove the oil filter
- Move the oil drain pan (at least 10-quart capacity) under the oil filter area (some oil will spill).
- Use an oil filter wrench to loosen the filter, then spin it off by hand.
- Make sure the old rubber gasket came off with the old filter. If it sticks to the engine, peel it off with a rag. Double-gasket = big leak.
Step 6: Install the new oil filter
- Put a thin smear of new oil on the new filterās rubber gasket using a gloved finger (this helps it seal).
- Spin the new filter on by hand until the gasket touches, then tighten an additional 3/4 turn by hand.
- Do not use the oil filter wrench to tighten (itās mainly for removal).
Step 7: Refill with new oil
- Insert a funnel into the oil fill and add 6 quarts of SAE 5W-30 dexos1-approved oil.
- Reinstall the oil fill cap by hand.
Step 8: Start, check for leaks, and verify level
- Start the engine and let it idle for 30-60 seconds.
- Shut the engine off and wait 2-3 minutes, then check the dipstick level and top off if needed.
- Look underneath with safety glasses for leaks at the drain plug and oil filter area.
- Wipe any drips with shop rags.
Step 9: Reset the Oil Life Monitor
- Method A (most Sierra 1500 clusters with DIC buttons): Turn ignition to ON (engine off) and use the steering wheel buttons to display Oil Life, then press and hold SET/CLR until it resets to 100%.
- Method B (if your cluster uses the pedal reset): Turn ignition to ON (engine off), then press the accelerator pedal fully 3 times within 5 seconds. The oil life should reset.
ā After Repair
- Recheck the dipstick the next day (after a short drive and cool-down) and top off if needed.
- Pour used oil into a sealed container and take it (and the old filter) to an oil recycling drop-off.
- If you see any fresh drips, recheck filter tightness (hand-tight only) and verify the drain plug is torqued correctly.
