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 to prevent any electrical issues during repair.

2. Change Engine Oil and Filter

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Place an oil catch pan under the oil pan.
3. Remove the oil drain plug and allow the old oil to drain completely.
4. Replace the oil filter using an oil filter wrench; ensure the rubber O-ring is removed with the old filter.
5. Reinstall the drain plug with the appropriate torque (typically around 30 Nm).
6. Fill the engine with new oil of the correct specification (5W-40 or as per manufacturer’s recommendation), using a funnel.
7. Start the engine and let it run for a few minutes, then check for leaks around the oil filter and drain plug.

3. Inspect and Replace Oil Pump (if necessary)

Sub-steps:
1. Remove any necessary components to access the oil pump (e.g., timing cover).
2. Disconnect the oil pump from the engine block, noting the orientation and connection points.
3. Inspect the old oil pump for wear or damage.
4. Install the new oil pump, ensuring proper alignment and sealing.
5. Reassemble any components removed during the process.
