Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Check and Top-Up Engine Oil

Remove the oil filler cap and check the oil level using the dipstick.
Add the appropriate oil (refer to owner's manual for specifications) if the level is low.
Replace the oil filler cap securely.

3. Replace Oil Filter

Prepare the area with an oil catch basin to collect any spilled oil.
Locate the oil filter (typically under the vehicle).
Use an oil filter wrench to remove the old oil filter.
Lubricate the rubber gasket on the new oil filter with a bit of fresh oil.
Install the new oil filter, tightening it by hand until snug.

4. Change Engine Oil

Locate the oil drain plug underneath the vehicle.
Use a socket set to remove the drain plug, allowing the old oil to drain completely.
Replace the drain plug and tighten it to the manufacturer's torque specifications.
Pour in new engine oil through the oil filler cap, using the manufacturer-recommended type and volume.

5. Inspect and Replace Oil Pressure Sending Unit (if necessary)

Locate the oil pressure sending unit, typically near the oil filter or on the engine block.
Disconnect the electrical connector from the sending unit.
Use a wrench to remove the sending unit.
Install the new sending unit and reconnect the electrical connector.
