Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal.

2. Check Oil Level

Remove the dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level.
If low, add the correct type of oil (5W-20 recommended) until the proper level is reached.

3. Inspect for Oil Leaks

Visually inspect the oil pan, oil filter, and oil lines.
Clean any spilled oil for better visibility.
If leaks are found, proceed to replace the faulty component (e.g., oil filter, gasket).

4. Test Oil Pressure

Remove the oil pressure sending unit using a socket wrench.
Install a mechanical oil pressure gauge in its place.
Start the engine and observe the oil pressure reading; it should typically be between 25-65 psi at idle and higher when revved.

5. Replace Oil Pump (if necessary)

If oil pressure is low, drain the engine oil and remove the oil pan.
Remove the oil pump from the engine and inspect it for wear or damage.
Install a new oil pump, ensuring the oil pump drive is properly aligned.
Reinstall the oil pan with a new gasket, torquing bolts to manufacturer specifications.

6. Reinstall Oil Pressure Sending Unit

Reinstall the oil pressure sending unit and reconnect any electrical connections.
Reconnect the negative battery terminal.
