Solution

1. Preparation

Gather all tools and materials required for the repair.
Ensure the engine is cool and parked on a level surface.
Disconnect the negative battery terminal for safety.

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 fully drain.
- Reinstall the drain plug and torque it to the manufacturer’s specifications (typically around 25 Nm).
Remove Oil Filter
- Use an oil filter wrench to remove the old oil filter. Ensure to lubricate the rubber gasket of the new filter with a small amount of fresh oil.
- Install the new oil filter, tightening it by hand until snug.
Add New Oil
- Refer to the owner's manual for the correct oil type and capacity (usually 5W-30 or 0W-40).
- Pour new oil into the engine through the oil fill cap.
- Check the oil level with the dipstick and add oil as necessary.

3. Check and Replace Oil Pressure Switch (if needed)

Locate the Oil Pressure Switch
- Identify the oil pressure switch on the engine, usually near the oil filter.
Remove Old Switch
- Disconnect the electrical connector from the oil pressure switch.
- Use a socket to remove the switch from the engine block.
Install New Switch
- Install the new oil pressure switch and torque it to the manufacturer's specifications.
- Reconnect the electrical connector.

4. Test Oil Pressure

Reconnect the negative battery terminal.
Start the engine and let it idle.
Use an oil pressure gauge to confirm that the oil pressure is within the normal operating range.
