1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety during repairs.

2. Change Engine Oil and Filter

Sub-steps:
1. Remove the oil drain plug using a socket set and allow old oil to drain completely.
2. Replace the oil filter with a new one.
3. Reinstall the oil drain plug and torque it to the specified value (typically around 30 ft-lbs).
4. Refill the engine with the recommended oil type (typically 0W-20 for the Corolla) until the proper level is reached.

3. Repair or Replace Noisy Components

Sub-steps:
1. If the noise is determined to be from the timing chain/belt, remove any covers to access it.
2. Inspect the timing chain tensioner and guides for wear. Replace any damaged components.
3. If the accessory belt is noisy, remove it and inspect for fraying; replace if necessary.
4. Tighten or replace any loose pulleys or mounts contributing to the noise.

4. Reassemble and Reconnect

Sub-steps:
1. Reinstall any components or covers that were removed during the inspection.
