At first I would smell a very slight/faint coolant smell when I was driving around town. I figured that it was excess coolant burning off from when I did my heater hose relocation and spilled some inside the engine bay. Then it started getting worse and worse, to where I could smell it any time I messed with my defroster or heater. Then it got to the point where it was unbearable to turn the heat/defroster on inside the car. The entire cabin smelled like coolant, and I did some research and saw that a few members had their heater cores go out. Took it to the dealership this morning and they called me back within 3 hours to confirm it was the heater core.
