Had the same problems this week that you are having...don't waste your time on the temp sensor. That's only going to control the guage, not the heat in the car. Waters not circulating in there at all. When you pull that water pump off, you'll see the problem. It'll probably fall right out. Plastic impeller is gone in that little jewel. Don't drive the car until you get it fixed. A $70 WP will cost you big bucks if you fry that engine. Check NAPA or AutoZone. NAPA part # is Duropro 125-1910. Autozone is A125-1910. Pump has a metal impeller that you'll never have to worry about. Good luck.
