Hi there. When coolant gets hot, it expands. Which is why the overflow reservoir exists. If the vehicle tends to overheat during the hot summer season, it may be contributed to the air conditioning system. Anytime you turn the AC on, it’s puts more stress and load on the engine; which can create overheating issues if there is a small coolant leak or issue with cooling system components. Since it’s Winter, it might be a good idea to have a professional mechanic complete an overheating inspection; to ensure that your PT Cruiser does not have engine issues next year or in the near future.
