Sub-steps:
1. Remove the engine cover (if applicable) using a socket set.
2. Visually inspect the timing chain for signs of wear, such as fraying or elongation.
3. Check the timing chain tensioner for proper function.

3. Replacement Procedure (if necessary)

Sub-steps:
1. Disconnect the battery to ensure safety.
2. Remove necessary components to access the timing chain, including the front engine cover.
