Solution

1. Preparation

Tools Required: OBD-II scanner, mechanic's stethoscope, socket set, torque wrench, engine oil, oil filter.
Park the vehicle on a level surface and ensure the engine is cool.

2. Check and Change Engine Oil

Sub-steps:
1. Locate the oil dipstick and check the oil level.
2. If low, add the recommended engine oil type (typically 5W-20 for this model).
3. If oil is dirty or due for a change, proceed to change the oil.
  - Place an oil pan under the oil pan and remove the drain plug using a socket wrench.
  - Allow the oil to completely drain, then replace the drain plug.
  - Remove the old oil filter using an oil filter wrench and install a new one, ensuring to lubricate the gasket with new oil.
  - Fill the engine with new oil through the oil filler cap.

3. Inspect and Adjust Valvetrain Components

Sub-steps:
1. Remove the engine cover to access the valvetrain.
2. Check for loose or damaged rocker arms, pushrods, or lifters.
3. If adjustments are required, refer to the service manual for specific torque values and procedures.
4. Reassemble the engine cover after inspection.

4. Inspect Exhaust and Accessory Components

Sub-steps:
1. Visually inspect the exhaust system for loose bolts, heat shields, or cracks.
2. Tighten any loose components and replace damaged parts as necessary.
3. Check accessory components for play or wear; replace as needed.
