Preparing Your Truck

Follow these steps carefully. They will help you get ready to change your truck’s engine oil smoothly.

Warm Up The Engine

Start the engine and let it run for a few minutes. Warm oil flows out faster and drains more completely. Turn off the engine before you begin the oil change. Be careful; the engine and oil may be hot. Warm oil helps remove dirt and old particles easily.

Install The New Filter

Before installing, apply a thin layer of new oil on the filter’s rubber gasket. This helps create a good seal. Screw the new filter by hand until it fits snugly. Tighten it a little more, but do not over-tighten.

Pour New Oil Into Engine

Open the engine oil cap on top of the engine. Use a funnel to avoid spills. Pour the correct type and amount of oil recommended for your GMC Sierra 1500. Pour slowly to let the oil flow smoothly. Stop pouring when you reach the required level.

Check Oil Level

Wait a few minutes after pouring oil to let it settle. Pull out the dipstick and wipe it clean. Reinsert the dipstick fully, then pull it out again. Check the oil level on the dipstick marks. Add more oil if the level is too low. Do not overfill the engine with oil.

Post-change Checks

Recheck Oil Level

After the engine runs, turn it off and wait a few minutes. Pull out the oil dipstick and wipe it clean. Insert it back fully, then pull it out again to check the oil level. The oil should be between the “Min” and “Max” marks. Add more oil if needed, but do not overfill.
