Solution

1. Preparation

Gather tools and replacement parts.
Disconnect the battery to ensure safety during the repair.
Allow the engine to cool down before starting the procedure.

2. Remove Engine Covers

Sub-steps:
- Use a socket set to remove any plastic engine covers or components obstructing access to the timing belt.
- Keep all fasteners organized for reinstallation.

3. Remove the Timing Belt

Sub-steps:
- Align the crankshaft and camshaft timing marks to ensure correct timing during reinstallation.
- Release tension from the timing belt tensioner using the appropriate tool.
- Carefully remove the timing belt from the pulleys, ensuring that no other components are damaged in the process.

4. Inspect Components

Sub-steps:
- Check the timing belt tensioner and idler pulleys for wear; replace if necessary.
- Inspect water pump for leaks or wear, as it is advisable to replace it along with the timing belt.

5. Install New Timing Belt

Sub-steps:
- Position the new timing belt over the pulleys, ensuring it is seated properly and following the manufacturer’s routing.
- Reapply tension to the tensioner according to specifications.
- Rotate the crankshaft manually a few times to ensure proper alignment of timing marks.

6. Reassemble Engine Components

Sub-steps:
- Reinstall any engine covers or components removed earlier.
- Reconnect the battery and ensure all tools are removed from the engine bay.
