What you'll need:
* New oil: Consult your owner's manual for the correct type and quantity (usually 4-5 quarts of 5W-30).
* New oil filter: Again, check your owner's manual for the correct filter. Auto parts stores can help you find the right one based on your vehicle's VIN or engine type.
* Oil filter wrench: The type depends on your car's filter; some are cap-type, others require a strap wrench.
* Wrench for the drain plug: Usually a 15mm socket wrench.
* Drain pan: A large enough container to hold at least 5 quarts of oil.
* Funnel: To make pouring new oil easier.
* Jack and jack stands (or ramps): Essential for safety; never work under a car supported only by a jack.
* Gloves: To keep your hands clean.
* Rags or paper towels: For cleanup.
* Torque wrench (optional but recommended): To tighten the drain plug to the correct specification (found in your owner's manual).
Steps:
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, though.
2. Prepare the car: Park on a level surface, engage the parking brake firmly, and chock the wheels (if using jack stands). Locate the oil drain plug underneath the engine (usually on the oil pan).
3. Raise the car: Carefully jack up the car and securely position it on jack stands. Ensure the car is stable before proceeding. If using ramps, drive the car onto them slowly and carefully.
4. Locate the drain plug and oil filter: The drain plug is usually located on the bottom of the oil pan. The oil filter is typically accessible from the bottom or the side of the engine.
5. Drain the old oil: Position the drain pan under the drain plug. Carefully loosen the drain plug using the appropriate wrench. Once loosened, unscrew it by hand (be careful; the oil will be hot). Let the oil drain completely – this may take 15-20 minutes.
6. Replace the oil filter: Using the oil filter wrench, carefully loosen and remove the old oil filter. Lightly lubricate the rubber gasket on the new oil filter with fresh oil. Screw on the new filter by hand until it's snug. Tighten it further according to the instructions on the filter's packaging (usually about ¾ to 1 full turn after the gasket contacts the engine).
7. Replace the drain plug: Once the oil has finished draining, carefully screw the drain plug back into the oil pan. Tighten it securely with your wrench, but don't overtighten. If using a torque wrench, tighten it to the manufacturer's specified torque (check your owner's manual).
8. Lower the car: Carefully lower the car using the jack.
9. Add new oil: Using the funnel, add the correct amount of new oil as specified in your owner's manual.
10. Check the oil level: Use the dipstick to check the oil level. Add more oil if necessary to reach the "full" mark.
11. Run the engine: Start the engine and let it run for a few minutes. Check for any leaks around the drain plug and oil filter.
12. Check the oil level again: After running the engine, turn it off and wait a few minutes for the oil to settle. Check the oil level again using the dipstick and add more if needed.
13. Dispose of the used oil properly: Take the used oil to a recycling center or auto parts store that accepts used oil.
Important Safety Notes:
* Always use jack stands: Never work under a car supported only by a jack.
* Wear safety glasses: Protect your eyes from splashing oil.
* Let the oil cool: Hot oil can cause serious burns.
* Consult your owner's manual: This guide provides general instructions. Always refer to your owner's manual for specific information about your 2005 Chevy Cavalier.
If you're uncomfortable performing this task yourself, take your car to a qualified mechanic. It's a relatively inexpensive service, and it's safer to have a professional handle it if you lack experience.
