1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect and Replace Engine Oil

Sub-step 1: Remove the oil drain plug using a socket wrench and drain the old oil into a suitable container.

Sub-step 3: Reinstall the oil drain plug and torque it to the manufacturer's specification (typically around 25-30 lb-ft).
Sub-step 4: Refill the engine with the recommended type and amount of oil (typically 5W-30 or as specified in the manual).

3. Inspect Engine Components

Sub-step 1: Remove any covers or shields obstructing access to engine components.
Sub-step 2: Check the timing chain/belt for wear or looseness. If damaged, replace it according to the manufacturer’s specifications.
Sub-step 3: Inspect the serpentine belt for cracks or fraying. Replace if necessary.
Sub-step 4: Check motor mounts for wear or damage and replace if they are cracked or damaged.

4. Test Drive

Sub-step 1: Reconnect the negative battery terminal.
Sub-step 2: Start the engine and allow it to reach operating temperature while monitoring for noise.
Sub-step 3: Take the vehicle for a test drive to ensure the noise has been resolved and performance is restored.
