Cabin blowing cold or windows fogging up? A vw Passat heater core replacement starts with the Four Seasons HVAC Heater Core 92186 — an aluminum heater core that circulates hot engine coolant so the blower can push warm air into the cabin and help clear the glass. It drops in as a direct-fit replacement across a wide range of Volkswagen models, including the 2006-2010 and 2012-2022 Passat, 2009-2012 Passat CC, 2010-2014 Golf and GTI, 2009-2017 Tiguan, 2012-2019 Beetle, 2009-2017 CC, 2009-2016 EOS and 2006-2009 Rabbit — see the Buyer's Guide tab for the full list.
- Aluminum construction for the core.
- Heavy-duty build for durability.
- O.E. fit, form and function from Four Seasons' quality engineering.
- Independently tested for proven quality and performance.
Signs the original core may need replacing include weak or no cabin heat, a sweet coolant odor inside, a greasy film or persistent fog on the windshield, or unexplained coolant loss. Because those symptoms can have other causes, diagnose the system first; if a failed heater core is the cause, this unit replaces it. Backed by Four Seasons' decades of mobile A/C experience.
