Drain Oil:
- Place an oil drain pan under the oil pan.
- Remove the oil drain plug using a socket set and allow the old oil to drain completely.
Replace Oil Filter:
- Remove the old oil filter using an oil filter wrench.
- Apply a thin layer of new oil to the rubber gasket of the new filter and install it.
Fill with New Oil:
- Replace the drain plug and torque it to the manufacturer's specifications.
- Add the recommended type and amount of new engine oil through the oil filler cap.

3. Tighten or Replace Loose Components

Engine Components:
- Inspect all accessible bolts and screws on the engine for tightness.
- Tighten any loose hardware and replace any damaged components (e.g., engine mounts, heat shields).

4. Inspect and Replace Timing Chain/Belt (if necessary)

Remove the Timing Cover:
- Disconnect any components that obstruct access to the timing cover (e.g., serpentine belt).
- Remove the timing cover bolts and gently pry the cover off.
Examine Timing Chain/Belt:
- Check for wear, slack, or damage.
- If replacement is needed, remove the old chain/belt and install the new one, following the manufacturer’s timing marks and specifications.
