Solution

1. Preparation

Gather tools and materials.
Tools Required:
- Socket set
- Torque wrench
- Stethoscope
- OBD-II scanner
- Engine oil (if necessary for reassembly)

2. Remove Engine Cover

Disconnect the negative battery terminal.
Remove all bolts securing the engine cover using the socket set.
Gently lift off the engine cover and set it aside.

3. Inspect Timing Chain

Visually examine the timing chain for any signs of wear, such as fraying or stretching.
Check the timing chain tensioner for proper operation; it should not be loose or overly tight.
Inspect the timing chain guides for cracks or excessive wear.

4. Rotate Engine and Check Timing Marks

Using a socket on the crankshaft pulley, rotate the engine clockwise until the timing marks on the crankshaft and camshaft align.
Ensure the marks align with the specified timing indicators as per the service manual.

5. Reassemble and Secure Components

If any issues were found during inspection, replace the timing chain and components as necessary.
Reinstall the engine cover and tighten all bolts to the manufacturer's specified torque.
Reconnect the negative battery terminal.
