6G Celicas Forums

So today she is driving the Celica, turns on the heat to defrost the windows, and suddenly smoke pours out of the vents. Any ideas what this could be?. I just put the car back together again but didn't do really anything to the heating system minus a new radiator. Did move the dash a bit so I guess I could have dislodged something but I doubt it would be enough for it to catch fire.

That is very interesting. So this happened all of a sudden? Meaning that you have used the heater before in this car many of time? Or did you purchase it off someone and first time discovering this problem? Not that I would know, but I would wonder if maybe a recent oil change (Maybe some got spilt and is burning?) or if maybe coolant is leaking out from under the hood and it is coming out through there. I had a crack on my radiator and under my hood smoked like crazy. Anyways, I hope you trace the problem soon.
