I had my dog in the car when the heater coil (or however you say it). He got a taste of the antifreeze into his mouth and had to be treated. It drained out all over my floorboard.

Monte Carlo SS 3.8L V6

I am back at the dealership again. this time my heater core actually exploded in my car (gross) and now it is being replaced. Remember just 3000 (3 months before) I was at the dealership because of a swooshing noise I swore was coming from my heater core. really upsetting because this could have been prevented!
