Carefully slide the old belt off the pulleys.
Route the new serpentine belt according to the diagram located on the engine bay.
Re-engage the tensioner to secure the new belt.

4. Check and Replace Tensioner (if necessary)

Tools Required: Socket set, torque wrench
Remove the tensioner from its mounting point using the socket set.
Install the new tensioner and torque it to the manufacturer’s specifications (usually around 30-40 Nm).
Make sure the tensioner is properly aligned.

5. Inspect Drive Pulleys

Tools Required: Wrench set
Examine each drive pulley for wear or damage.
Replace any worn or misaligned pulleys as necessary.

6. Reconnect Battery and Test
