Solution

1. Preparation

Tools Required: Socket set, torque wrench, timing belt tool kit, screwdrivers, jack and jack stands, oil catch pan, and a clean workspace.
Disconnect the negative battery terminal to prevent electrical shorts.
Raise the front of the vehicle using a jack and secure it with jack stands.
Remove any engine covers or components obstructing access to the timing belt.

2. Remove the Old Timing Belt

Sub-steps:
1. Remove the Serpentine Belt: Use a serpentine belt tool to relieve tension and remove the belt.
2. Remove the Timing Belt Covers: Unbolt and carefully remove the upper and lower timing belt covers.
3. Align Timing Marks: Rotate the crankshaft to align the timing marks on the crankshaft and camshaft gears.
4. Remove the Timing Belt Tensioner: Unbolt the tensioner and remove it.
5. Remove the Timing Belt: Slide the old timing belt off the camshaft and crankshaft gears.

3. Install the New Timing Belt

Sub-steps:
1. Inspect and Replace Components: Check the water pump, tensioner, and idler pulleys for wear. Replace if necessary.
2. Place New Timing Belt: Starting from the crankshaft, loop the new timing belt around the crankshaft, idler, and camshaft gears, ensuring that the timing marks remain aligned.
3. Install Tensioner: Reinstall the timing belt tensioner and tighten it according to the manufacturer's specifications.
4. Double-check Timing Marks: Ensure all timing marks are still aligned after the tensioner is installed.
5. Reinstall Timing Covers: Bolt the timing covers back on securely.

4. Reassemble and Test

Sub-steps:
1. Reinstall Serpentine Belt: Ensure the serpentine belt is properly routed and tensioned.
2. Reconnect Battery: Reconnect the negative battery terminal.
3. Start the Engine: Start the engine and listen for unusual noises, confirming smooth operation.
