Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety while working.

2. Check and Add Oil

Remove the dipstick and wipe it clean.
Reinsert it fully, then remove it again to check the oil level.
If low, add the appropriate type and amount of oil (consult the owner’s manual for specifications).

3. Replace Oil Filter

Use an oil filter wrench to remove the old oil filter.
Lubricate the rubber O-ring of the new filter with fresh oil.
Install the new oil filter by hand until snug, then tighten it according to specifications.

4. Replace Engine Oil

Place a drain pan under the oil pan.
Remove the drain plug and allow the old oil to completely drain out.
Reinstall the drain plug and tighten it to the specified torque.
Pour in the new oil through the oil fill cap, using the correct type and amount.

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

Locate the oil pressure sending unit (usually near the oil filter).
Disconnect the electrical connector and remove the unit using a socket.
Install the new oil pressure sending unit and reconnect the electrical connector.

6. Final Checks

Reconnect the battery.
Start the engine and allow it to idle, checking for oil leaks.
Monitor the oil pressure gauge to ensure it is within normal range.
