Solution

1. Preparation

Tools Required: OBD-II scanner, mechanic's stethoscope, socket set, torque wrench, and safety glasses.
Safety Warnings: Disconnect the battery before working on electrical systems. Allow the engine to cool before performing inspections.

2. Change Engine Oil and Filter

Sub-steps:
1. Raise the vehicle securely on jack stands.
2. Place an oil catch pan underneath the oil pan, then remove the oil drain plug and drain the old oil.
3. Replace the oil filter using an oil filter wrench.
4. Reinstall the drain plug and tighten it to the manufacturer's torque specification (typically around 25-30 Nm).
5. Refill the engine with the appropriate type and quantity of oil (check the owner's manual, usually 5W-30 or 0W-30).
6. Start the engine and check for leaks around the drain plug and filter.

3. Replace Timing Chain/Belt Tensioner (if necessary)

Sub-steps:
1. Remove any components obstructing access to the timing cover (e.g., engine covers, accessory belts).
2. Remove the timing cover bolts and carefully take off the timing cover.
3. Inspect the timing chain/belt and tensioner for wear. Replace the tensioner if it is worn or not holding proper tension.
4. Reinstall the timing cover and torque bolts to the manufacturer's specification.
5. Reinstall any components removed in the previous step.
