Thank you. I hate to say it but you have the infamous engine that has a ton of cylinder head issues. I would do a block test before anything else. You can usually get a block test kit at most auto parts stores. It tests for combustion gas in the coolant. If it comes back positive then the engine will need to come apart. If not then you may have a restriction or cooling fan issue that I can help you diagnose.
