The Hella Heater Core is a direct OE replacement for your vehicles stock heater core. A faulty or malfunctioning heater core can be easily diagnosed as a coolant leak when the system is cold (this leak will usually drip into the floor of your cabin) or simply by an inability to heat your car in the colder months. The Heater Core is a critical component in your vehicles HVAC system.
Note: A diagnostic scan of your vehicle is an effective way of discerning the cause of the fault in your HVAC system.
