Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent any electrical issues.

2. Change Engine Oil and Filter

Drain Old Oil:
- Place an oil catch pan under the oil pan.
- Remove the oil drain plug using a socket wrench and allow the oil to completely drain.
Replace Oil Filter:
- Locate the oil filter; use an oil filter wrench to remove it.
- Apply a small amount of new oil to the rubber seal of the new filter.
- Install the new oil filter and tighten it according to the manufacturer's specifications.
Add New Oil:
- Replace the oil drain plug and tighten it to the specified torque (usually around 25 Nm).
- Use a funnel to add the manufacturer-recommended oil type (e.g., 5W-30) through the oil filler cap.
- Check the oil level with the dipstick and add more oil if necessary.

3. Inspect and Replace Oil Pump (if necessary)

Remove Oil Pump:
- Drain the oil again if necessary.
- Remove any components obstructing access to the oil pump (e.g., timing cover).
- Unscrew the oil pump bolts and carefully remove the oil pump.
Inspect Oil Pump:
- Check for wear or damage on the pump gears.
- Replace the oil pump with a new unit if found defective.
Reassemble:
- Reinstall all removed components.
- Ensure all bolts are torqued to specifications.
