2. Loosen the tensioner bolt and remove the serpentine belt.
3. Inspect the tensioner; replace if faulty.
4. Install a new belt following the routing diagram in the engine compartment.
5. Reconnect the tensioner and tighten to manufacturer specifications.

4. Inspect and Replace Idler Pulley or Alternator

Sub-steps:
1. Disconnect the negative battery terminal.
2. Remove the serpentine belt to access the idler pulley or alternator.
3. Spin the idler pulley by hand; it should turn smoothly without noise.
4. If faulty, remove the idler pulley with a socket set and replace it with a new part.
5. Reinstall the belt and reconnect the battery.

5. Check Transmission Fluid

Sub-steps:
