Solution

1. Preparation

Gather necessary tools and parts.
Tools Required:
- OBD-II scanner
- Socket set
- Torque wrench
- Screwdrivers
- Timing belt kit (belt, tensioner, idler pulley)
- Engine support bar (if necessary)
Disconnect the battery to ensure safety while working.

2. Remove Components

Remove the engine cover and any components obstructing access to the timing belt, such as the air intake duct, engine mount (if required), and accessory belts.
Sub-steps:
- Loosen and remove screws/bolts securing the engine cover.
- Detach the air intake duct by loosening clamps and removing screws.
- Support the engine if the engine mount needs to be removed, then take off the mount.

3. Access the Timing Belt

Remove the timing belt cover to expose the timing belt.
Sub-steps:
- Unscrew and remove the bolts holding the timing cover.
- Carefully remove the cover to prevent damage to the gasket.

4. Replace the Timing Belt

Align the timing marks on the crankshaft and camshaft to ensure proper timing.
Remove the old timing belt, tensioner, and idler pulley.
Install the new tensioner and idler pulley, ensuring they are torqued to specifications.
Install the new timing belt, ensuring it is properly aligned with timing marks.
Sub-steps:
- Rotate the tensioner to apply tension to the belt and secure it in place.
- Double-check the alignment of timing marks after installing the belt.

5. Reassemble Components

Reinstall the timing belt cover and any components that were removed.
Reattach the engine mount and other accessories that were taken off.
Sub-steps:
- Ensure all bolts are torqued to manufacturer specifications.
- Reinstall the air intake duct and engine cover.

6. Final Checks

Reconnect the battery and start the engine.
Check for abnormal noises and ensure the engine runs smoothly.
