• 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
