Allow the engine to cool down before working.
Disconnect the battery to prevent electrical shorts.

2. Check and Replace Engine Oil

Sub-steps:
1. Remove the oil filler cap and use a dipstick to check the oil level.
2. If low, drain the old oil using a wrench to remove the oil drain plug.
3. Replace the oil drain plug and tighten to the manufacturer's torque specification (typically around 25 Nm).
4. Replace with the appropriate grade of oil as specified in the owner's manual (e.g., 5W-30).
5. Replace the oil filler cap securely.

3. Inspect and Replace Oil Filter

Sub-steps:
1. Locate the oil filter and use an oil filter wrench to remove it.
2. Apply a thin layer of new oil to the rubber gasket of the new oil filter.
3. Install the new oil filter by hand, tightening it according to the manufacturer's specifications (usually 3/4 to 1 full turn after the gasket makes contact).

4. Test the Oil Pump

Sub-steps:
1. Remove the oil pump access cover if applicable.
2. Inspect the pump visually for damage or wear.
3. If necessary, replace the oil pump following the manufacturer's service manual instructions.

5. Reconnect Battery and Test

Sub-steps:
1. Reconnect the battery terminals.
2. Start the engine and allow it to idle for a few minutes.
