Changing the oil on a Chevy equipped with an underbody oil drain system can be a straightforward process if you follow the right best practices. This system is designed to make oil changes cleaner and more efficient, but it requires specific steps to ensure proper maintenance and avoid damage.
Preparation Before the Oil Change
Before starting, gather all necessary tools and materials. You will need:
- New engine oil specified for your Chevy model
- New oil filter
- Wrench set
- Drain pan
- Safety gloves and glasses
- Rags or towels
Ensure the vehicle is parked on a level surface and the engine is cool to prevent burns. Engage the parking brake for safety.
Draining the Old Oil
Locate the underbody oil drain system, which typically features a drain plug or valve. Follow your vehicle’s manual for exact location. Carefully open the drain valve or remove the plug to allow the old oil to flow into the drain pan.
Be prepared for a sudden flow of oil. Keep the drain pan aligned properly to catch all the oil and prevent spills. Once the flow slows, close the drain valve securely.
Replacing the Oil Filter
Locate the oil filter, which is usually accessible from underneath or the engine bay. Use an oil filter wrench to remove the old filter. Be cautious as residual oil may still be inside.
Apply a light coat of new oil to the gasket of the new filter before installing it. Screw the new filter in by hand, then tighten it according to the manufacturer’s specifications.
Refilling with New Oil
Open the underbody drain valve or replace the drain plug if it was removed. Pour the new engine oil into the designated fill port. Use the amount specified in your vehicle’s manual.
After filling, start the engine and let it run for a few minutes. Check for leaks around the drain system and oil filter. Turn off the engine and wait a few minutes for the oil to settle.
Use the dipstick to verify the oil level. Add more oil if necessary to reach the recommended level.
Final Checks and Cleanup
Ensure the drain valve is securely closed and the oil cap is properly tightened. Clean any spilled oil and dispose of the used oil and filters at a proper recycling center.
Record the date and mileage of the oil change for future reference. Regular oil changes help maintain engine health and performance.
