2. Inspect and Replace Serpentine Belt

Tools Required: Socket set, belt tensioner tool
Remove the belt tensioner using the socket set.
Slide the serpentine belt off the pulleys and inspect for cracks or wear.
Replace the belt if damaged, ensuring it is routed correctly over the pulleys.
Reinstall the tensioner and tighten to manufacturer specifications.

3. Check and Replace Engine Mounts (if necessary)

Tools Required: Socket set, jack, and block of wood
Use a jack to support the engine slightly.
Remove the bolts securing the engine mount to the subframe and engine.
Replace with new engine mounts and tighten bolts to specifications.
Lower the engine and ensure the mounts are aligned correctly.
