Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Allow the engine to cool if it has been running.

2. Check and Top Off Engine Oil

Remove the oil dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level.
If low, add the appropriate type of engine oil (refer to the owner’s manual for specifications).
Start the engine and let it idle for a few minutes, then recheck the oil level.

3. Replace Oil Filter (if necessary)

Gather tools: oil filter wrench, drain pan, and new oil filter.
Place the drain 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 filter.
Install the new filter, tightening it by hand until snug.

4. Replace Engine Oil (if necessary)

Use a socket set to remove the drain plug and allow the old oil to drain completely into the drain pan.
Replace the drain plug and tighten it to the manufacturer’s torque specification (typically around 25-30 ft-lbs).
Pour the new engine oil into the engine using a funnel, ensuring to use the correct oil type and quantity.

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

Disconnect the battery to ensure safety.
Locate the oil pressure sending unit, typically near the oil filter.
Disconnect the electrical connector and remove the sending unit using a socket wrench.
Install the new sending unit and reconnect the electrical connector.
Reconnect the battery.
