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 electrical shorts.

2. Change Engine Oil and Filter

Sub-steps:
1. Locate and remove the engine oil drain plug using a socket wrench; allow oil to drain completely into a pan.
2. Replace the oil filter with a new one, ensuring the rubber O-ring is lubricated with new oil before installation.
3. Reinstall the drain plug and torque it to the manufacturer’s specifications (typically around 20-30 Nm).

3. Inspect and Replace Oil Pump (if necessary)

Sub-steps:
1. Remove any components obstructing access to the oil pump (e.g., front engine cover).
2. Disconnect the oil lines from the oil pump.
3. Remove the oil pump mounting bolts and take out the old oil pump.
4. Install the new oil pump, ensuring it is aligned properly, and torque the bolts to the manufacturer’s specifications.

4. Check Oil Pressure Sending Unit

Sub-steps:
1. Locate the oil pressure sending unit on the engine.
2. Disconnect the electrical connector and unscrew the unit.
3. Install a new oil pressure sending unit and reconnect the electrical connector.

5. Refill Engine Oil

Sub-steps:
1. Add the appropriate type and amount of engine oil (check the owner's manual for specifications).
2. Start the engine and let it idle for a few minutes while checking for leaks around the oil filter and drain plug.
