- Remove the belt using a serpentine belt tool or socket wrench on the tensioner.
- Inspect for wear, cracks, or fraying.
Sub-steps:
- If damaged, replace the belt with a new one.
- Inspect pulleys for smooth operation and replace any that are damaged or noisy.

4. Check and Replace Transmission Mounts

Mount Inspection:
- Raise the vehicle safely on jack stands.
- Inspect the transmission mounts for cracks or excessive wear.
Sub-steps:
- If necessary, remove the bolts securing the mounts and replace them with new mounts.
