Solution

1. Preparation

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

Tools Required:

OBD-II scanner
Oil pressure gauge
Socket set
Wrench set
Torque wrench
Oil filter wrench
Clean rags

2. Check and Change Oil

Step 1: Remove the oil drain plug using a socket wrench and allow the oil to drain completely into a pan.
Step 2: Replace the oil filter using an oil filter wrench; ensure the rubber O-ring is removed with the old filter.
Step 3: Reinstall the oil drain plug and torque it to the manufacturer's specifications (typically around 20-25 ft-lbs, check specific values for S650).
Step 4: Fill the engine with the appropriate type and amount of oil (5W-30 synthetic oil recommended for S650).

3. Replace Oil Pressure Sending Unit (if faulty)

Step 1: Locate the oil pressure sending unit, typically near the oil filter or at the engine's rear.
Step 2: Disconnect the electrical connector from the sending unit.
Step 3: Use a socket to remove the old sending unit and install the new one, tightening it to the manufacturer's specifications (generally around 15-20 ft-lbs).
Step 4: Reconnect the electrical connector securely.

4. Verify Oil Pressure

Step 1: Install an external oil pressure gauge by removing the oil pressure sending unit and threading the gauge into place.
Step 2: Start the engine and monitor the gauge readings; normal pressure is typically between 25-65 psi at idle and higher during acceleration.
Step 3: If pressure is low, confirm the oil pump is functioning correctly.
