overheated, keeps overheating

Many possibilities here. Make sure the engine fan is kicking on. You are also going to need to check for leaks so rent a pressure tester at a local auto parts store. Don't throw any parts at the car as you may be wasting money. A complete diagnosis is always best. Use this link to find a good shop near you. https://repairpal.com/repair-shops Alex

Until you get the cooling system fixed I don't recommend running you're car past it's normal operating temperature. Or at all if possible. In my case I had a bad water pump a brand new defective thermostat and enough eletrical problems to scare me out of having a battery connected with the car off.
