1. Place an oil drain pan under the oil pan.
2. Remove the oil drain plug using a socket wrench (typically 17mm).
3. Allow all oil to drain completely into the pan.
Tools Required:
- Oil drain pan
- Socket wrench set

3. Replace Oil Filter

Sub-steps:
1. Locate the oil filter; it may require an oil filter wrench to remove.
2. Remove the old oil filter and inspect the O-ring for damage.
3. Apply a thin layer of new oil to the O-ring of the new filter.
4. Install the new oil filter, ensuring it is snug but not overly tight.
Tools Required:
- Oil filter wrench
- New oil filter

4. Inspect and Replace Gaskets/Seals

Sub-steps:
1. If the oil pan gasket or valve cover gasket is leaking, use a gasket scraper to remove old gaskets.
2. Clean the mating surfaces with a solvent to ensure a good seal.
3. Install new gaskets, ensuring they are aligned correctly.
4. Torque the valve cover bolts and oil pan bolts to manufacturer specifications (typically around 10-12 lb-ft).
Tools Required:
- Gasket scraper
- Torque wrench
- Solvent for cleaning

5. Refill Engine Oil

Sub-steps:
1. Replace the oil drain plug and tighten it securely.
2. Use a funnel to pour new engine oil into the fill cap (refer to owner's manual for the correct oil type and capacity).
3. Start the engine and let it idle for a few minutes, checking for leaks around the oil filter and drain plug.
Tools Required:
- Funnel
