What you'll need:
* New oil: Refer to your owner's manual for the correct type and quantity. (Typically 4-5 quarts)
* New oil filter: Again, consult your owner's manual or check the filter at an auto parts store using your car's details.
* Oil filter wrench: The correct size will depend on your car; a cap-type wrench or strap wrench often works well.
* Wrench for the drain plug: Usually a 14mm or 15mm socket. Double-check your vehicle.
* Drain pan: Large enough to hold at least 5 quarts of oil.
* Funnel: To avoid spills when adding new oil.
* Jack and jack stands (or ramps): Essential for safe access to the drain plug. Never work under a car supported only by a jack.
* Gloves: To protect your hands.
* Rags or paper towels: To clean up spills.
* Torque wrench (optional but recommended): For tightening the drain plug to the manufacturer's specification (prevents leaks and damage).
Procedure:
1. Warm up the engine: Run the engine for 5-10 minutes to warm the oil, making it flow more easily. Don't let it get too hot to touch, though.
2. Secure the vehicle: Use a jack and jack stands (or ramps) to safely lift the car. Ensure it's stable and level.
3. Locate the oil drain plug: It's usually located on the bottom of the oil pan, towards the front of the engine.
4. Position the drain pan: Place the drain pan under the drain plug.
5. Remove the drain plug: Carefully loosen and remove the drain plug using the appropriate wrench. Let the oil drain completely; this may take 15-20 minutes. Be careful, the oil will be hot.
6. Locate the oil filter: It's typically located near the oil drain plug, but the exact location varies by engine.
7. Remove the old oil filter: Use the oil filter wrench to loosen and remove the old filter. Some oil will likely spill, so be prepared.
8. Lubricate the new oil filter's gasket: Lightly lubricate the rubber gasket of the new oil filter with fresh oil.
9. Install the new oil filter: Screw on the new oil filter by hand until it's snug. Then tighten it according to the instructions on the filter (usually about ¾ to 1 full turn after the gasket contacts the engine block).
10. Replace the drain plug: Once the oil has finished draining, carefully reinstall the drain plug and tighten it securely using your wrench. If you have a torque wrench, use it to tighten to the manufacturer's specified torque.
11. Lower the vehicle: Carefully lower the vehicle using the jack.
12. Add new oil: Remove the oil fill cap (usually located on top of the engine) and use a funnel to add the correct amount of new oil, as specified in your owner's manual.
13. Check the oil level: After adding the oil, check the oil level using the dipstick. Add more oil if needed to reach the "full" mark.
14. Run the engine: Run the engine for a few minutes.
15. Check for leaks: Carefully inspect the area around the drain plug and oil filter for any leaks.
16. Check the oil level again: After running the engine, turn it off and wait a few minutes. Then check the oil level again and add more if necessary.
Disposal: Dispose of the used oil and filter properly. Most auto parts stores accept used oil for recycling.
Remember to always consult your owner's manual for specific instructions and recommendations for your 2005 Chevy Malibu Classic. If you're uncomfortable performing this task yourself, it's best to take your car to a qualified mechanic.
