Solution

1. Preparation

Tools Required: Socket set, OBD-II scanner, mechanic's stethoscope
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical shorts.

2. Check and Change Engine Oil

2. If oil is dirty or old, drain the engine oil using a socket set to remove the oil drain plug.
3. Replace the oil filter using an oil filter wrench.
4. Refill with fresh oil as per the manufacturer’s specifications (check owner's manual for oil type and capacity).

3. Inspect Belts and Pulleys

Sub-steps:
1. Visually inspect serpentine and timing belts for cracks or fraying.
2. Check tension on the belts; replace if loose or damaged.
3. Inspect pulleys for wear; replace any that show signs of damage.

4. Check Exhaust System

Sub-steps:
1. Inspect the exhaust manifold and pipes for leaks or loose connections.
2. Tighten any loose bolts or replace gaskets if necessary to eliminate noise.

5. Evaluate Starter Motor

Sub-steps:
1. Test the starter motor by checking for secure connections and proper operation.
2. Replace starter motor if it shows signs of wear or failure.
