I just changed the thermostat the other day and It turns out it was a 195... now I believe i have the 50/50 coolant in their and the car runs fine but then jolts up to 230 and then depending the car will run there for a while or bobble between 210 or so... I believe the thermosta is not opening because their is no pressure at time in the upper rad. hose and my overflow tank is full... any advice will help alot... I mean it is the dead of winter in NY and is cirrentyl about 10 deg out so it shouldnt be overheating... is the thermostat frozen stuck or what?!!?!
