Solution

1. Preparation

Tools Required: Socket set, torque wrench, timing belt kit, OBD-II scanner, flathead screwdriver, ratchet, and extension.
Disconnect the negative battery cable to prevent electrical shorts.
Allow the engine to cool down before starting work.

2. Remove Engine Covers

Use a socket set to remove the plastic engine cover and any other covers obstructing access to the timing belt.
Set aside screws and components in a labeled container to avoid misplacement.

3. Access Timing Belt

Remove the drive belts by loosening the tensioner and sliding belts off the pulleys.
Remove the crankshaft pulley bolt with a socket and ratchet. Use a breaker bar if necessary.
Take off the crankshaft pulley using a puller if needed.

4. Timing Belt Removal

Set the engine to Top Dead Center (TDC) by aligning the marks on the crankshaft and camshaft pulleys.
Remove any timing belt tensioner and idler pulleys.
Carefully slide the old timing belt off the pulleys.

5. Install New Timing Belt

Install the new timing belt onto the crankshaft first, ensuring proper alignment with the marked camshaft and crankshaft.
Replace the tensioner and idler pulleys, ensuring they are torqued to the manufacturer's specifications.
Adjust the tension on the timing belt according to the specifications.

6. Reassemble Components

Reinstall the crankshaft pulley and torque the bolt to the specified value.
Reinstall the drive belts and adjust the tension.
Replace any engine covers removed earlier and secure them with screws.

7. Final Checks

Reconnect the negative battery cable.
Start the engine and check for any abnormal noises or leaks.
