Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery for safety.

2. Change Engine Oil and Filter

Drain Old Oil:
- Place an oil drain pan under the oil pan.
- Remove the oil drain plug using a socket set and allow oil to fully drain.
- Reinstall the drain plug and torque it to the manufacturer's specifications (usually around 25 Nm).
Replace Oil Filter:
- Locate the oil filter and use an oil filter wrench to remove it.
- Lubricate the rubber O-ring on the new oil filter with fresh oil.
- Install the new oil filter by hand until snug, then tighten it an additional 3/4 turn.
Add New Oil:
- Pour the recommended type and amount of engine oil into the oil filler cap.
- Use a funnel to avoid spills, and check the oil level with the dipstick.

3. Inspect and Replace Oil Pump (if necessary)

Remove Engine Cover: Unscrew and take off the engine cover to access the oil pump.
Disconnect Oil Pump: Remove any hoses or connections to the oil pump.
Unbolt Oil Pump: Use a socket set to remove the bolts securing the oil pump to the engine block.
Install New Oil Pump: Position the new oil pump, secure it with bolts, and reconnect any hoses or connections.
