About Hyundai Heater Core
Since your engine produces so much heat that has to be expelled anyway, the engineers decided to send it through a Hyundai heater core to warm the passenger compartment instead of using an electric or gas-fired heater. But as your car ages, the heater core suffers from the same problems that your vehicle's radiator suffers from: corrosion and leaks. If you've changed your antifreeze religiously every two years or so, you may not have any crud built up in your heater core. Once your Hyundai heater core begins to leak, interior damage, foul odors, mold, and rust are close behind.
