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. Check Oil Level and Condition

Remove the dipstick, wipe it clean, and reinsert it.
Check the oil level, ensuring it is between the minimum and maximum marks.
If oil is low, add the manufacturer-recommended oil type.

3. Replace Oil Filter

Use an oil filter wrench to remove the old oil filter.
Before installing the new filter, apply a thin layer of oil to the rubber O-ring on the new filter.
Install the new filter, tightening it according to the manufacturer's specifications (usually hand-tight plus 3/4 turn).

4. Change Engine Oil

Place an oil drain pan under the oil pan.
Remove the oil drain plug using a socket wrench and allow the old oil to drain completely.
Replace the drain plug and tighten it to the manufacturer's torque specifications (typically around 20-25 ft-lbs).
Refill the engine with the recommended oil type and quantity.

5. Replace Oil Pressure Sending Unit (if necessary)

Locate the oil pressure sending unit on the engine block.
Disconnect the electrical connector and remove the unit using a socket wrench.
Install the new oil pressure sending unit and reconnect the electrical connector.
