Solution

1. Preparation

Gather tools and parts required.
Disconnect the battery (negative terminal) to prevent electrical shorts.
Raise the front of the vehicle and secure it on jack stands.

2. Remove Components

Remove the engine cover if equipped.
Disconnect any components obstructing access to the timing belt (e.g., air intake duct, engine mount, or pulleys).
Remove the serpentine belt by releasing tension on the tensioner.

3. Access Timing Belt

Remove the timing belt cover by unscrewing the bolts.
Rotate the crankshaft to align the timing marks on the crankshaft and camshaft pulleys to ensure the engine is at Top Dead Center (TDC).

4. Remove the Old Timing Belt

Loosen the timing belt tensioner bolt and remove the tensioner.
Slide the old timing belt off the pulleys.

5. Install New Timing Belt

Position the new timing belt around the crankshaft and camshaft pulleys, ensuring it is snug but not overly tight.
Install the timing belt tensioner and set it to the specified tension.
Rotate the crankshaft two full revolutions to ensure proper alignment of timing marks.

6. Reassemble Components

Reinstall the timing belt cover and any components removed in reverse order.
Reattach the serpentine belt and tensioner.
Reconnect the battery.
