Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Gather necessary tools and parts.
Disconnect the battery to prevent electrical hazards.

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 drain pan under the oil pan.
3. Remove the oil drain plug and allow the old oil to fully drain.
4. Replace the oil filter using an oil filter wrench.
5. Install a new oil drain plug with the correct torque (typically around 25 Nm).
6. Refill the engine with the correct type and amount of oil as specified in the owner’s manual (usually 5W-40 synthetic oil).

3. Inspect and Replace Oil Pump (if necessary)

Sub-steps:
1. Remove the engine cover and any components obstructing access to the oil pump.
2. Disconnect the oil lines from the pump.
3. Unbolt the oil pump and remove it from the engine.
4. Compare the new oil pump with the old one to ensure compatibility.
5. Install the new oil pump and connect the oil lines.
6. Reassemble any removed components and engine cover.

4. Final Checks

Sub-steps:
1. Reconnect the battery.
2. Start the engine and let it idle for a few minutes.
3. Check for leaks around the oil filter and drain plug.
4. Monitor the oil pressure gauge to ensure normal readings.
