Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Allow the engine to cool down completely before beginning work.

2. Check Oil Level

Remove the dipstick, wipe it clean, reinsert it, and then remove it again to check the oil level.
If the oil is low, add the appropriate type and quantity of oil as specified in the owner’s manual.

3. Replace Oil Filter (if necessary)

Tools Required: Oil filter wrench, oil catch pan, socket set.
Place the oil catch pan under the oil filter.
Use the oil filter wrench to remove the old oil filter.
Apply a small amount of new oil to the rubber gasket of the new oil filter.
Install the new oil filter by hand, tightening it according to the manufacturer's specifications.

4. Replace Engine Oil

Tools Required: Socket set, oil catch pan, funnel.
Remove the oil drain plug using a socket set and allow old oil to fully drain into the catch pan.
Replace the drain plug and torque it to the manufacturer's specification.
Use a funnel to pour new oil into the engine, ensuring the correct oil type and quantity.

5. Test Oil Pressure

Tools Required: Mechanical oil pressure gauge.
Locate the oil pressure sending unit and remove it.
Install the mechanical oil pressure gauge in its place.
Start the engine and observe the pressure reading on the gauge. It should be within the manufacturer’s specified range.

6. Reassemble and Clean Up

If oil pressure is normal, reinstall the oil pressure sending unit.
Dispose of old oil and filter according to local regulations.
Close the hood and ensure all tools are removed from the engine bay.
