Since the first time my thermostat went out less than two years ago, my thermostat has had to be replaced seven times. We started noticing the O-ring that is in it is shrinking and stops sealing. They cost $130 at the nearby auto parts store. Luckily the part has a warranty so it has not cost me each time. This car is junk. They are made it so cheaply they do not last. I purchased this car brand new.
