Four Seasons HVAC Heater Core P/N:90769
Bring heat back to the cabin with the FOUR SEASONS heater core (P/N 92378), a specific-fit replacement for the 2016-2019 Hyundai Sonata, the 2017-2020 Kia Cadenza, and the 2016-2020 Kia Optima, all engines. The heater core is a compact coolant-to-air heat exchanger: hot engine coolant circulates through its aluminum tubes while the blower pushes cabin air across the fins, warming the interior and helping clear the windshield during defrost.
If a leaking or clogged original heater core is the cause of weak cabin heat, a sweet coolant odor, or fogged glass, this Four Seasons hvac heater core replaces it. Backed by over 50 years of mobile A/C experience. Diagnose the cooling system before replacing to confirm the core is at fault.
