Model Years Affected: 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010

Exhaust & Emissions Affected: 3.7L V6

Verified

The 3.7L V6 and 4.7L V8 in very cold climates (below freezing temperatures) moisture can collect in the Positive Crankcase Ventilation (PCV) system and freeze. This will cause various drivability problems and there are revised PCV system components to repair this concern.
