Welcome to the forum, If I suspect an engine coolant issue, I check the coolant level, in radiator and overflow bottle, where applicable. Don't remove radiator cap from hot radiator. If the coolant flow is stopped somehow, the overflow bottle usually fills up in a hurry. The radiator fan should be running if engine is hot? On some make and models, if the ac is turned on, the fan turns on. If the coolant temp sensor is unplugged, the fan will run.
Check for trouble codes. How long since a tune-up?
