coolant mist spewing from heater vents...

Car fogs up whenever I use the heater, and I mean fogs up to the point where I can't see anything.

It reeks of coolant whenever the heater is on as well.

Could it be the heater core? Or Temperature sensor? Or what?

I'm going to venture that your heater core is shot. Only way to know is pull everything out and inspect it.

you know its very simple to replace the core...mayb a 2 hour job...only car i know where the dash doesnt have to be removed is the camaro and firebird. i replaced mine with a 7mm socket, some extentions and a 7mm wrench. thers an article in the tech centre on how to do it simply by taking off the dashboard and the passenger side lower dash.
