I have a 2000 SE with 155,xxx miles on it. I noticed that my heat does not warm up unless I drive the car. Meaning, if I let the car run/idle for 10 mins or 30 mins it makes no difference as far as the warm air coming out of the vents...none does. Once I drive the car for 10 mins or so, it will warm up fine. I also notice a smell of anti-freeze once driving it. The temp gauge is about in the center which reads about 200 degrees. (Might be a little on the high side?) The car has stalled a couple times recently when shifting from park. Any and all thoughts are welcome.

Thanks!

FYI.....is now fixed. Was the heater core.
