Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Change Engine Oil and Filter

Drain the old oil:
- Place an oil drain pan under the oil pan.
- Remove the drain plug and allow the oil to fully drain.
- Reinstall the drain plug and torque to manufacturer specifications (typically around 25-30 ft-lbs).
Replace the oil filter:
- Use an oil filter wrench to remove the old oil filter.
- Lubricate the rubber O-ring of the new oil filter with fresh oil.
- Install the new oil filter by hand until snug, then tighten according to the manufacturer's recommendation (usually 3/4 turn after the O-ring contacts the base).

3. Check and Replace Oil Pump (if necessary)

Remove the oil pan:
- Support the engine with a jack and remove the oil pan bolts.
- Carefully lower the oil pan and inspect the gasket for damage.
Replace the oil pump:
- Disconnect any necessary components (e.g., oil pickup tube).
- Remove the old oil pump and install the new one.
- Reinstall the oil pickup tube and ensure it is properly seated.
- Reinstall the oil pan with a new gasket and torque bolts to specification.

4. Refill Engine Oil

Refill the engine with the recommended oil type and viscosity (typically 0W-20 or as specified).
Start the engine and let it idle for a few minutes, checking for leaks.
