Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool down completely.

2. Remove Engine Covers

Remove any plastic engine covers using a socket set (typically 10mm).
Carefully set aside the covers for reinstallation later.

3. Access the Timing Belt

Remove the serpentine belt by loosening the tensioner using a ratchet and appropriate socket.
Remove the alternator and any components obstructing access to the timing belt (e.g., the crankshaft pulley).
Use a socket and ratchet to remove the timing belt cover bolts.

4. Replace Timing Belt

Align the timing marks on the crankshaft and camshaft sprockets to ensure proper timing.
Loosen the timing belt tensioner and remove the old timing belt.
Install the new timing belt, ensuring it is taut on the tensioner side and correctly seated on all pulleys.

5. Reassemble Components

Reinstall the timing belt cover and ensure it is securely fastened.
Reinstall the alternator and any other components removed during the process.
Reinstall the serpentine belt and adjust the tension.

6. Final Checks

Reconnect the negative battery terminal.
Start the engine and listen for unusual noises.
Check for any leaks around the timing cover area.
