Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery terminals to ensure safety.
Raise the vehicle using a jack and secure it with jack stands.

2. Remove Components

Remove the engine covers and accessories obstructing access to the timing belt.
Detach the serpentine belt by releasing the tensioner.
Remove the front motor mount (if necessary) to gain access to the timing belt area.

3. Remove the Timing Belt

Align the engine at TDC (Top Dead Center) on the crankshaft.
Remove the timing belt cover bolts and take off the cover.
Loosen and remove the tensioner bolt and take off the tensioner.
Carefully slide the timing belt off the camshaft and crankshaft pulleys.

4. Install New Timing Belt

Position the new timing belt onto the crankshaft pulley, ensuring it is aligned with the timing marks.
Route the belt around the idler pulley and then the camshaft pulley.
Install the new tensioner and tighten it to the manufacturer's specifications.
Rotate the engine manually two full revolutions and re-check the alignment of timing marks.

5. Reassemble Components

Reinstall the timing belt cover and securely fasten it.
Reattach the front motor mount and any other components removed earlier.
Install the serpentine belt, ensuring the correct routing.
Reconnect the battery terminals.
