I was driving about an hour with the ac and noticed a rise in the thermostat but it went back down a few times. At one point it got to the danger zone but went down quickly. There I knew there was a problem. Again it went to the danger zone so I decided to stop but I waited for an exit; I would say I drove 1 maybe 1.5 miles before I took the exit on the freeway. The car had burned through the coolant and was making a bad noise where the reserve coolant tank is and shaking it slightly. I filled it with water and drove back, which was about 95 miles to get home and it went fine. I'm gonna get it checked before replacing with 50/50 coolant.
I'm worried that extra driving caused something serious. Yes I'm an idiot for not stopping immediately, I'm a young driver. Again, the car drove perfectly fine after filling with water for 95 miles.
