Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to avoid any electrical shorts.
Ensure the engine is cool before working on it.

2. Remove Engine Covers

Use a socket set to remove any plastic engine covers obstructing access to the timing belt.
Carefully set aside the covers ensuring no clips are lost.

3. Inspect and Replace Timing Belt

Inspect: Check the condition of the timing belt, tensioner, and idler pulleys.
Replace:
1. Remove the timing belt tensioner using a socket set.
  - Tools Required: Socket set, torque wrench.
2. Slide off the old timing belt from the camshaft and crankshaft pulleys.
3. Install the new timing belt, ensuring it is properly aligned with the timing marks on the pulleys.
4. Reinstall the tensioner and adjust it to the manufacturer's specified torque.
  - Torque specifications: Refer to the service manual for exact torque values.

4. Reassemble Engine Covers

Reinstall any engine covers removed in Step 2.
Ensure all bolts are tightened to the specified torque using a torque wrench.

5. Reconnect Battery and Test

Reconnect the battery terminals.
Start the engine and listen for any abnormal noises.
Allow the engine to reach operating temperature to check for belt function.
