Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Safety warning: Allow the engine to cool before proceeding to avoid burns.

2. Check Oil Level

Remove the dipstick and wipe it clean.
Reinsert the dipstick and pull it out again to check the oil level.
If low, add the appropriate oil type (5W-20 or as specified in the owner’s manual) until the correct level is achieved.

3. Replace Oil Filter

Tools Required: Oil filter wrench, oil catch pan
Place the oil catch pan under the oil filter.
Use the oil filter wrench to remove the old oil filter.
Apply a thin layer of fresh oil to the rubber gasket of the new filter, then install it by hand until snug.

4. Change Engine Oil

Tools Required: Socket set, oil catch pan
Drain the old oil by removing the drain plug with a socket wrench and allowing it to flow into the catch pan.
Replace the drain plug and tighten to the specified torque (usually around 20-25 lb-ft).
Refill the engine with new oil using a funnel, ensuring to add the correct amount (usually around 6-8 quarts).

5. Replace Oil Pressure Sending Unit (if necessary)

Tools Required: Socket set, torque wrench
Disconnect the battery to ensure safety.
Locate the oil pressure sending unit (usually near the oil filter).
Remove the electrical connector and unscrew the sending unit with a socket.
Install the new sending unit and reconnect the electrical connector.
Reconnect the battery.

6. Test Oil Pressure

Tools Required: Mechanical oil pressure gauge
Remove the oil pressure sending unit and install the mechanical gauge in its place.
Start the engine and observe the pressure reading; it should be within the manufacturer’s specified range (usually 20-60 psi).
If pressure is low, further diagnostics may be necessary for oil pump issues.
