The PT Cruiser thermostat is easy to replace. If your car is overheating but you have plenty of coolant then this might be your problem. To change the thermostat all you have to do is unbolt the radiator fill cap and you have fast access. It is not the easiest thermostat to get to but it isnt bad. It could also be due to a bad head gasket which is what happened to mine. *If the video was helpful, remember to give it a "thumbs up" and consider subscribing.
