Spectra Premium HVAC Heater Core P/N:98036
Bring warm air back to the cabin with the Spectra Premium HVAC Heater Core 98036. It installs as a direct-fit replacement for the 2007-2009 Mazda 3, the 2009 Mazda 3 Sport, and the 2006-2007 Mazda 5, restoring the coolant-to-air heat exchanger that feeds your climate system.
A heater core works like a small radiator: hot engine coolant flows through its tubes while the blower pushes cabin air across the fins, transferring that heat into the interior. When the core clogs, corrodes, or leaks, you may notice weak heat, fogged windows, a sweet coolant smell, or damp carpet — signs this part may need replacing. Diagnose the cause before swapping it.
