Solution

1. Preparation

Gather tools and parts necessary for the repair.
Disconnect the negative battery terminal to prevent electrical shorts.
Raise the vehicle using a jack and secure it with jack stands.

2. Remove Engine Covers

Remove the plastic engine cover by unscrewing the bolts.
Take off the front engine cover using a socket set to access the timing belt.

3. Remove Accessory Components

Detach the serpentine belt using a belt tensioner tool.
Remove any components blocking access to the timing belt, such as the alternator or power steering pump, by loosening their mounting bolts.

4. Remove the Old Timing Belt

Align the timing marks on the crankshaft and camshaft.
Loosen the timing belt tensioner and remove the old timing belt from the pulleys.
Inspect the tensioner and idler pulleys for wear and replace if necessary.

5. Install New Timing Belt

Place the new timing belt onto the crankshaft and camshaft pulleys, ensuring it is properly aligned with the timing marks.
Reinstall the timing belt tensioner and adjust it to the correct tension according to the manufacturer’s specifications.

6. Reassemble Components

Reinstall any components removed earlier, such as the power steering pump and alternator.
Reattach the serpentine belt and ensure proper tension.
Replace the front engine cover and the plastic engine cover.

7. Final Checks

Reconnect the negative battery terminal.
Start the engine and listen for any abnormal noises.
Check for leaks around the timing cover and adjust if necessary.
