Alright, so the other day I started my car early to warm up. Gave it maybe 15 minutes and when I came back outside my temp gauge was off the radar, car completely overheated. So I shut it off for awhile, and then crank her up again and start driving. Well when I am driving all temps are great, but as soon as I stop at a light or something it only takes about a minute for the car to over heat again. My thermostat is new, 170 degrees, bought it from summit a couple months back and haven't had any problems unit today. Should i replace it, or could it be from low coolant levels in the car?

Any ideas??
