Q: Car overheated on freeway

Hello. If the car will only overheat on the freeway and not anywhere else, I suspect you may have a common civic issue, which is a failing head gasket. Head gasket repair is generally pretty expensive. But there are other components that may cause the same overheating concern, such as a bad water pump or thermostat. I suggest checking these first before taking the expensive repair route. If you need further assistance, I recommend you have a mechanic, like one from YourMechanic, inspect the overheating issue and make the necessary repairs.
