Steps to Change the Oil in a 2004 Silverado 5.3

Changing the oil yourself can save money and ensure it’s done correctly. Here’s how to do it:

1. Gather Supplies

6 quarts of SAE 5W-30 motor oil
New oil filter (such as ACDelco PF46 or equivalent)
Oil drain pan
Wrench or socket set
Oil filter wrench
Funnel
Rags or paper towels

2. Warm Up the Engine

Let the engine run for 5–10 minutes to warm up the oil, making it easier to drain.

3. Lift the Truck (if needed)

Use ramps or jack stands for better access to the oil pan.

4. Drain the Oil

Locate the oil drain plug underneath the engine.
Place the drain pan under the plug and use a wrench to remove it.
Let the oil fully drain (5–10 minutes).

5. Replace the Oil Filter

Use the filter wrench to remove the old filter.
Lightly oil the gasket on the new filter.
Install the new filter by hand—do not overtighten.

6. Add New Oil

Reinstall the drain plug.
Use a funnel to pour in 6 quarts of new oil through the oil cap.
Check the oil level using the dipstick and top off if necessary.

7. Run the Engine and Check for Leaks

Start the engine, run it for a few minutes, and check for leaks around the oil filter and drain plug.

8. Dispose of the Used Oil Properly. Take the used oil and filter to a recycling center or auto parts store that accepts them.
