Keep warm air flowing into the cabin with the Four Seasons hvac heater core 98048, an aluminum heater core that carries hot engine coolant through its core so the blower can warm the interior and help clear the glass. It fits many vehicles, among them the 1997-2005 Volkswagen Jetta, 1999-2006 Volkswagen Golf and 2011-2012 Audi Clasico, and installs as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list and engine details.
Four Seasons designs and tests its products with years of trouble-free operation as the goal, and it draws on more than 50 years of mobile A/C experience.
Signs a heater core may need replacing include weak or no cabin heat, a sweet coolant smell inside the vehicle, damp floor carpet, fogged windows, or coolant loss with no visible outside leak. If a leaking or clogged heater core is the cause, this unit replaces it.
