Solution

1. Preparation

Tools Required: OBD-II scanner, mechanic's stethoscope, socket set, torque wrench.
Safety Warnings: Disconnect the battery before starting any work on the engine.

2. Change Engine Oil

Sub-steps:
1. Raise the vehicle securely on jack stands.
2. Drain the old engine oil by removing the oil drain plug.
3. Replace the oil filter using an oil filter wrench.
4. Install the drain plug with the recommended torque specification (typically around 25 Nm).
5. Refill the engine with the manufacturer-recommended oil type and capacity.

3. Adjust Valve Clearance (if applicable)

Sub-steps:
1. Remove the valve cover using a socket set.
2. Rotate the engine to the specified position to access the cylinder you are adjusting.
3. Measure valve clearance using a feeler gauge.
4. If necessary, adjust the clearance by replacing shims or adjusting the rocker arms as per the service manual specifications.
5. Reinstall the valve cover with a new gasket, tightening to the specified torque.

4. Inspect and Replace Timing Components (if necessary)

Sub-steps:
1. Remove front engine covers to access the timing belt/chain.
2. Inspect for wear, cracks, or looseness in the belt/chain.
3. If damaged, replace the timing belt/chain following manufacturer specifications.
4. Reassemble all components and ensure proper alignment.
