Summary
Service Update. Certain vehicles may have a condition in which ice or sludge can accumulate in the Charge Air Cooler (CAC) or Closed Crankcase Ventilation (CCV) system when driving in extremely cold weather conditions (-18°C (0°F) or less). Dealers will install a TCV thermal wrap and, if applicable, reprogram the Engine Control Module.
